Intel Announces 8th-Generation Whiskey Lake and Amber Lake Processors Suitable for MacBook and MacBook Air

Intel this afternoon officially debuted its new eighth-generation U-series "Whiskey Lake" and Y-series "Amber Lake" chips, which are designed for use in thin, light notebooks like the MacBook and the MacBook Air. The new "Amber Lake" Y-series processors, which include the i7-8500Y, i5-8200Y, and the m3-8100Y, are successors to the current chips that Apple uses in the 12-inch MacBook lineup. Apple is working on updated 12-inch MacBook models set to come out this fall that could use the new Amber Lake processors. Intel's new 15W U-series "Whiskey Lake" chips, which include the i7-8565U, i5-8265U, and i3-8145U, would be appropriate for a refreshed MacBook Air, and rumors have suggested that such a machine is perhaps in the works. While details haven't been entirely clear, Apple is working on a followup to the MacBook Air that features a 13-inch Retina display, and if this machine uses chips similar to the chips that MacBook Air models have used for years, the new Whiskey Lake chips are suitable. According to Intel, its new Whiskey Lake and Amber Lake chips "raise the bar for connectivity, performance, entertainment, and productivity." The U-series chips introduce support for integrated Gigabit Wi-Fi for up to 12-times faster connectivity speeds, support for USB 3.1 Gen 2 transfer speeds, and built-in support for voice services like Alexa and Cortana. Intel says that compared to a 5-year-old PC, the new U-series processors offer two times better performance and double-digit gains in office productivity for everyday web browsing and content creation over

Throttling in New i9 MacBook Pros Appears to be Due to Power Delivery Chip

A user posting on reddit and in the MacRumors forums has given a detailed account of their findings and attempts to circumvent the throttling previously discovered on the new MacBook Pro 15" models featuring the six-core i9 Intel CPUs. The user goes on to explain that one of the internal power limits set for the device may not be appropriate for the power draw of the CPU and identical to previous MacBook Pro models, causing the power delivery chip (known as a voltage regulation module, or VRM) to report an over power condition that forces the clock of the CPU down to scale back power. This sets up the same conditions to allow throttling to occur once again. These conditions may be presenting themselves due to the new six-core design of the i9 CPU featured here. While Intel increased the core count of the CPU, they did not increase the thermal design power (TDP), or the amount of dissipated power manufacturers should plan to have to cool for a proper CPU design. This is an issue because this number usually reflects normal usage, and does not account for turbo modes. It's also likely it can exceed the draw of previous four core CPUs given the similarity of clock speeds and process nodes they are featured on. A method for tuning this limit is provided in the post, but it requires executing a command manually or via script each time the computer boots, and would likely void the warranty if Apple technicians discovered it. Still, the user posts results of benchmarks showing successive runs with no throttling. Manufacturers will always quote likely reduced component

Intel Reportedly Halts Development of 5G Modem After Losing Orders for 2020 iPhones

Apple has informed Intel that it will not use the chipmaker's 5G mobile modem in its 2020 iPhones, according to a new report. Israeli website CTech by Calcalist reported on Wednesday that it had reviewed internal communications from Intel and spoken to "people familiar with the matter", leading it to conclude that Intel will not provide the 5G modems for Apple's 2020 mobile devices. Apple has notified Intel it will not use a mobile modem developed by the chipmaker in its next-generation mobile device, Intel executives said in the communications. Further development of the modem component internally called "Sunny Peak" is halted and Intel's team working on the product will be redirected to other efforts, the executives said.Calcalist said the communications it had seen described Apple as the "key mobile customer" and the "main volume driver" for the "Sunny Peak" 5G mobile modem, underlining the impact the loss of business would have on the chipmaker. Apple was also said to be facing a "massive effort" to launch 5G in its mobile products, with Intel executives blaming the company's decision not to use its modems on "many factors", including the introduction of a faster WiGig (802.11ad) Wi-Fi standard, which brought "new and unanticipated challenges". In a response to Calcalist's request for comment, an Intel spokesman said the company does not comment on matters relating to its customers. The news follows one analyst's prediction last week that Apple could choose to use modems manufactured by MediaTek instead of Intel in future iPhones. Northland analyst

Intel May Lose Apple Modem Business to MediaTek

Apple may choose to use modems manufactured by MediaTek instead of modems from Intel in future iPhones, according to an investor's note from Northland analyst Gus Richard that was shared by Bloomberg. Little detail was included in the note, but Richard believes Apple could be planning to shift its modem business away from Intel. The accuracy of that prediction is questionable, however, and there's no clear timeline on when Apple might be planning to make the shift. Presumably this would impact 2019 iPhones, as deals for 2018 iPhones are established. For many years, Apple relied solely on Qualcomm chips, but added Intel as a manufacturer a couple years ago. Current iPhones use LTE chips from both Qualcomm and Intel, but Apple is embroiled in a lawsuit with Qualcomm and is rumored to be aiming to ditch Qualcomm chips, too. Given the sheer number of iPhones Apple produces each year, it's not clear if Apple could rely on MediaTek as sole supplier for its LTE chips, so the conflicting rumors of Apple cutting ties with both Intel and Qualcomm are somewhat confusing. Apple is developing its own modem chips to reduce its reliance on both Intel and Qualcomm, but it will need to continue to use third-party chips until its in-house solution is ready to be deployed in iOS devices. Current rumors suggest Intel will supply approximately 70 percent of LTE chips set to be used in the 2018 lineup, with the rest of the chips continuing to come from Qualcomm. Apple is also moving away from Intel chips in its Mac lineup, with rumors suggesting the company is developing its

Intel Discloses New 'Variant 4' Spectre-Like Vulnerability

Intel, Google, and Microsoft today disclosed a new variant of the Spectre design flaw and security vulnerability that impacts millions of computers and mobile devices from a range of manufacturers. Called Variant 4, or the Speculative Store Bypass, the vulnerability is similar to Spectre, taking advantage of the speculative execution mechanism of a CPU to allow hackers to gain access to sensitive information. Variant 4 was demonstrated by researchers in a language-based runtime environment. CVE-2018-3639 - Speculative Store Bypass (SSB) - also known as Variant 4 Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.According to Intel, the new vulnerability has a "moderate" severity rating because many of the exploits that it uses have already been addressed through mitigations that were first introduced by software makers and OEMs in January for Meltdown and Spectre. Intel is, however, releasing a full mitigation option that will "prevent this method from being used in other ways." This additional mitigation for Variant 4 has been delivered in beta form to OEM system manufacturers and system software vendors, and Intel is leaving it up to its partners to decide whether or not to implement the extra measures. Intel plans to leave the mitigation set to off by default because of the potential for performance issues.This mitigation will be set to

Intel Foundries Continue to Face Issues and Another Spectre-Like Vulnerability Disclosure May Be Looming

Despite positive first quarter results for 2018, Intel faces continuing issues with its foundries, both with the oft-delayed 10nm, as well as its own modem production in 14nm. Intel revealed in the earnings conference call that volume 10nm manufacturing had been delayed to 2019, without specifying which part of the year. The debut of Intel's 10nm process has been a particular sore spot, with the forthcoming Whiskey Lake set to be the fifth new architecture debut in the 14nm process. Prior to 14nm, Intel had maintained a two architecture, "tick-tock" strategy for its processors, where a new foundry node denoted a small architecture update over the previous processor as a "tick," and a more significant architectural evolution as a "tock" on a matured process. We first reported on the demise of the tick-tock strategy in 2016. Things have only grown worse for Intel since then as 10nm has faced further delays. To put this delay in perspective, Intel's original roadmaps had 10nm technology debuting in 2015. There are several reasons for the delay, but Intel CEO Brian Krzanich explained that some features in Intel's 10nm process require up to five or six multi-pattern steps, whereas other competing foundries are known for up to four steps in 10nm or 7nm processes. This development has consequences for Intel, its customers, and its competitors. First, Intel has lost the technology advantage it once held over the rest of the semiconductor industry. While you cannot compare the dimension in the node name directly across foundries, competitors such as TSMC, Samsung, and

Intel's New Core i9 and Coffee Lake Chips Pave Way for Quad-Core 13" MacBook Pro, Mac Mini Refresh, and More

Intel today introduced a range of new eighth-generation Core processors [PDF] appropriate for future MacBook Pro, Mac mini, and iMac models. The most notable new chip is the first-ever Core i9 processor for notebooks. With six cores and 12 threads, Intel says the Core i9 is the highest-performance notebook processor it has ever designed. The H-series processor has a 2.9GHz base clock speed with a Turbo Boost frequency of up to 4.8GHz. Given the Core i9 is a 45W chip, it is appropriate for the high-end 15-inch MacBook Pro and could be included in a refreshed version of the notebook as early as this year. Apple last updated the MacBook Pro lineup with Kaby Lake processors at WWDC in June 2017, so a Core i9 model could debut at WWDC 2018. Of note, while the Core i9 processor allows for systems with up to 32GB of RAM, this is unlikely to apply to the next MacBook Pro, since low-power DDR4 RAM is still not supported. Back in 2016, Apple's marketing chief Phil Schiller said 32GB of standard DDR4 RAM would compromise battery life. The eighth-generation Core processor family also includes new quad-core Core i5 and Core i7 processors with base clock speeds between 2.3GHz and 2.7GHz and integrated Iris Plus graphics. These 28W chips, part of the U-series, are suitable for future 13-inch MacBook Pro and Mac mini models. Intel says the new Core i9, i7, and i5 processors for notebooks are based on its Coffee Lake platform and leverage its 14nm++ manufacturing process, enabling the chips to deliver up to 41 percent more frames per second in gameplay or edit 4K video up

Intel's 8th-Gen Xeon and Core Processors Feature Redesigned Hardware to Address Spectre and Meltdown Vulnerabilities

Intel CEO Brian Krzanich today announced that its next-generation Xeon Scalable (Cascade Lake) processors and its 8th-generation Intel Core processors will feature redesigned components to protect against the Spectre and Meltdown vulnerabilities that affect all modern processors. Spectre variant 1 of the vulnerabilities will continue to be addressed in software, while Intel is implementing hardware-based design changes to offer future protection against Spectre variant 2 and Meltdown variant 3. We have redesigned parts of the processor to introduce new levels of protection through partitioning that will protect against both Variants 2 and 3. Think of this partitioning as additional "protective walls" between applications and user privilege levels to create an obstacle for bad actors.Intel's new Xeon Scalable processors and its 8th-generation Intel Core processors are expected to start shipping out to manufacturers in the second half of 2018. Ahead of the hardware changes, Intel says that software-based microcode updates have now been issued for 100 percent of Intel products launched in the past five years, and all customers should make sure to continue to keep their systems up-to-date with software updates. Krzanich also reaffirmed Intel's commitment to customer-first urgency, transparent and timely communications, and ongoing security reassurance. Apple began addressing the Meltdown and Spectre vulnerabilities back in early January with the release of iOS 11.2, macOS 10.13.2, and tvOS 11.2, which introduced mitigations for Meltdown. Subsequent iOS 11.2.2

KGI Expects Intel to Be Exclusive Supplier of Modems in 2018 iPhones

Intel could be the exclusive supplier of LTE modems for all new iPhones launched in 2018, according to KGI Securities analyst Ming-Chi Kuo. The key takeaway of the research note, obtained by MacRumors:We expect Intel to be the exclusive supplier of baseband chip for 2H18 new iPhone models, while Qualcomm may not have a share of the orders at all.Kuo previously expected Intel to supply 70 percent of the modems, with Qualcomm providing the remaining 30 percent of orders, but he now believes Intel will be the sole supplier given several competitive advantages. First and foremost, Intel's latest XMM 7560 modem [PDF] supports both GSM and CDMA, meaning that Apple could release a single iPhone model that works across AT&T, Verizon, T-Mobile, and Sprint. Intel modems previously lacked CDMA, meaning Apple could never fully ditch Qualcomm for all iPhone models. Apple is also embroiled in a major lawsuit with Qualcomm over anticompetitive licensing practices, and Kuo believes the iPhone maker switching to Intel as its exclusive modem supplier will place added pressure on Qualcomm. Kuo added that it's too early to tell if Intel will be able to maintain its position of exclusivity in the future, as Apple typically prefers to diversify its supply chain. He adds that Apple may give orders to Qualcomm again in exchange for concessions in the ongoing lawsuit between the two companies. Qualcomm was Apple's exclusive supplier of baseband chips until the iPhone 7 and iPhone 7 Plus, when Intel began to share some of the orders. In order to make up for the lost iPhone

Intel CEO Pledges Commitment to Security Following Meltdown and Spectre Vulnerabilities

Intel CEO Brian Krzanich today wrote an open letter to Intel customers following the "Meltdown" and "Spectre" hardware-based vulnerabilities that impact its processors. In the letter, Krzanich says that by January 15, updates will have been issued for at least 90 percent of Intel CPUs introduced in the past five years, with updates for the remainder coming at the end of January. For Apple customers, macOS and iOS devices have been patched with protection against Spectre and Meltdown. Meltdown was addressed in macOS High Sierra 10.13.2 and iOS 11.2, while Spectre mitigations were introduced in a macOS 10.13.2 supplemental update and iOS 11.2.2, both of which were released this week. The vulnerabilities have also been addressed in older versions of macOS and OS X. According to Krzanich, going forward, Intel promises to offer timely and transparent communications, with details on patch progress and performance data. Because Spectre and Meltdown are hardware-based vulnerabilities, they must be addressed through software workarounds. In some cases, these software patches cause machines to perform more slowly. Apple users do not need to worry about performance impacts. According to Apple, Meltdown had no measurable reduction in performance on devices running macOS and iOS across several benchmarks. Spectre, fixed through a Safari mitigation, had no measurable impact on most tests, but did impact performance by less than 2.5% on the JetStream benchmark. Apple says it plans to continue to refine its mitigations going further. In addition to remaining transparent

Intel Says New Software Updates Make Computers 'Immune' to Meltdown and Spectre Vulnerabilities

Intel today announced that the firmware updates and software patches that are being released for its CPUs render Intel-based computer systems "immune" to both the Spectre and Meltdown exploits that were widely publicized this week.Intel has developed and is rapidly issuing updates for all types of Intel-based computer systems -- including personal computers and servers -- that render those systems immune from both exploits (referred to as "Spectre" and "Meltdown") reported by Google Project Zero. Intel and its partners have made significant progress in deploying updates as both software patches and firmware updates.Intel says updates have been issued for the majority of Intel processor products introduced within the past five years, and by the end of next week, more than 90 percent of processor products from the last five years will be patched. For Mac users, Apple has already addressed some of the vulnerabilities in the macOS High Sierra 10.13.2 update, and further updates will come in macOS High Sierra 10.13.3. To make sure you're protected as a Mac user, install all of the latest operating system updates and firmware patches. As always, it's also worth avoiding suspicious programs, websites, and links. Intel today also reiterated that the updates that are being released for Mac, PC, and Linux machines should not significantly impact day to day usage and should, for the most part, be unnoticeable. That seems to be true of the macOS High Sierra 10.13.2 update, as there have been no reports of slowdowns from Mac users.Intel continues to believe that the performance

Intel Claims Security Flaw Also Impacts Non-Intel Chips, Exploits Can't Corrupt, Modify or Delete Data [Updated]

Intel this afternoon addressed reports of a serious design flaw and security vulnerability in its CPUs, shedding additional light on the issue that was uncovered yesterday and has since received extensive media coverage. In a statement on its website, Intel says that it planned to disclose the vulnerability next week when additional software patches were available, but was forced to make a statement today due to "inaccurate media reports." According to Intel, the issue is not limited to Intel chips and the exploits in question do not have the potential to corrupt, modify, or delete data. Despite Intel's statement, Intel chips are more heavily impacted, and it's worth noting that Intel makes no mention of reading kernel level data.Intel and other technology companies have been made aware of new security research describing software analysis methods that, when used for malicious purposes, have the potential to improperly gather sensitive data from computing devices that are operating as designed. Intel believes these exploits do not have the potential to corrupt, modify or delete data. Recent reports that these exploits are caused by a "bug" or a "flaw" and are unique to Intel products are incorrect. Based on the analysis to date, many types of computing devices -- with many different vendors' processors and operating systems -- are susceptible to these exploits.Intel says it is working with several other technology companies including AMD, ARM, and operating system vendors to "develop an industry-wide approach" to resolve the problem "promptly and constructively."

Intel Memory Access Design Flaw Already Addressed by Apple in macOS 10.13.2

A serious design flaw and security vulnerability discovered in Intel CPUs has reportedly already been partially addressed by Apple in the recent macOS 10.13.2 update, which was released to the public on December 6. According to developer Alex Ionescu, Apple introduced a fix in macOS 10.13.2, with additional tweaks set to be introduced in macOS 10.13.3, currently in beta testing. AppleInsider also says that it has heard from "multiple sources within Apple" that updates made in macOS 10.13.2 have mitigated "most" security concerns associated with the KPTI vulnerability. The question on everyone's minds: Does MacOS fix the Intel #KPTI Issue? Why yes, yes it does. Say hello to the "Double Map" since 10.13.2 -- and with some surprises in 10.13.3 (under Developer NDA so can't talk/show you). cc @i0n1c @s1guza @patrickwardle pic.twitter.com/S1YJ9tMS63— Alex Ionescu (@aionescu) January 3, 2018 Publicized yesterday, the design flaw in Intel chips allows normal user programs to see some of the contents of the protected kernel memory, potentially giving hackers and malicious programs access to sensitive information like passwords, login keys, and more. Full details on the vulnerability continue to be unavailable and under embargo, so it's not yet clear just how serious it is, but fixing it involves isolating the kernel's memory from user processes using Kernel Page Table Isolation at the OS level. Implementing Kernel Page Table Isolation could cause a performance hit on some machines. According to The Register, which first shared details on the vulnerability, Windows

Intel Chips Have Memory Access Design Flaw and Fix Could Lead to Performance Drop

A serious design flaw and security vulnerability has been discovered in Intel's CPUs that will require an update at the operating system level to fix, reports The Register. All modern computers with Intel chips from the last 10 years appear to be affected, including those running Windows, Linux, and macOS. Similar operating systems, such as Apple's 64-bit macOS, will also need to be updated - the flaw is in the Intel x86 hardware, and it appears a microcode update can't address it. It has to be fixed in software at the OS level, or go buy a new processor without the design blunder.Full details on the vulnerability aren't yet known as the information is currently under embargo until later in the month. The Register has unearthed some data, however, and it seems the bug allows normal user programs to see some of the contents of the protected kernel memory. This means malicious programs can potentially, in a worst case scenario, read the contents of the kernel memory, which can include information like passwords, login keys, and more. It's not yet clear how severe the bug is, but The Register speculates that it's significant given the rapid changes being made to Windows and Linux.At worst, the hole could be abused by programs and logged-in users to read the contents of the kernel's memory. Suffice to say, this is not great. The kernel's memory space is hidden from user processes and programs because it may contain all sorts of secrets, such as passwords, login keys, files cached from disk, and so on. Imagine a piece of JavaScript running in a browser, or malicious

iPhone X Models With Qualcomm Modem Still Have Faster LTE Speeds Than Those With Intel Modems

iPhone X models equipped with Qualcomm's Snapdragon X16 modem get consistently better LTE speeds than versions with Intel's XMM7480 modem, according to wireless signal testing firm Cellular Insights. For context, Cellular Insights used professional measurement equipment equipped with four Vivaldi antennas to simulate LTE performance at different distances from a cellular tower with the Qualcomm and Intel models. Cellular Insights started with a LTE signal from a strong -85dBm, and gradually reduced the power level to simulate moving away from a cellular tower where signal is weaker, until the modems lost their cellular connectivity. The testing, shared with PC Magazine, was based on performance on LTE Band 4, which is used by every major carrier in the United States except Sprint, as well as in Canada and parts of Latin America. The results reveal that with only limited attenuation, or signal reduction in simple terms, the iPhone X with an Intel modem started to experience lower LTE download speeds than the iPhone X with a Qualcomm modem.While both modems started out with 195Mbps of download throughput on a 20MHz carrier, the Qualcomm difference appeared quickly, as the Intel modem dropped to 169Mbps at -87dBm. The Qualcomm modem took an additional -6dBm of attenuation to get to that speed.Cellular Insights said the difference is most noticeable in very weak signal conditions, in which the iPhone X with a Qualcomm modem experienced 67 percent faster LTE download speeds on average compared to the Intel model.At very weak signal strength, below -120dBm, the

Apple Working With Intel on 5G Hardware for Future iPhones

Apple is "leaning heavily" towards choosing Intel's 5G modems for its future iPhones, according to Fast Company. Apple engineers are said to be already working with Intel on upcoming 5G technology. Apple's discussions with Qualcomm about 5G modems, meanwhile, have been described as "limited." Citing a source with knowledge of Apple's plans, Fast Company says that while Qualcomm 5G modems will offer more specialized carrier features, many of those features will not be adopted by carriers, leading Apple to believe Intel's hardware will be sufficient for future devices.The end game, multiple sources have said, is to build the Intel modem onto an integrated system-on-a-chip (SoC) that would also contain the CPU, GPU, and other iPhone components. The SoC would be co-designed by Intel and Apple and would be fabricated at an Intel facility.Intel reportedly has "multiple thousands" of people working on 5G technology in an effort to catch up with Qualcomm and win the contract from Apple. Intel this morning said that it had made "substantial advances" in its wireless product roadmap to accelerate the adoption of 5G. According to Intel, an end-to-end 5G call based on early 5G silicon has been completed successfully, which Intel says is a "key milestone in its development." Intel expects its first 5G chips to roll out in 2019, ahead of the wide rollout of 5G networks. T-Mobile just today said that it is planning to roll out its fifth-generation network across the United States by 2020, and most of the carriers in the United States are already experimenting with limited

Intel Teams Up With AMD for New 8th-Generation Processors With AMD GPUs

Longtime rivals Intel and AMD are joining forces to produce new 8th-Generation H-Series Intel mobile processors paired with stacked second-generation High Bandwidth Memory and custom-built discrete graphics from AMD, Intel announced today. For the new H-Series chips, which feature all of the above listed components in a single processor package, Intel says is using its Embedded Multi-Die Interconnect Bridge (EMIB), a power-sharing framework that reduces the standard silicon footprint to less than half that of standard discrete components on a motherboard.At the heart of this new design is EMIB, a small intelligent bridge that allows heterogeneous silicon to quickly pass information in extremely close proximity. EMIB eliminates height impact as well as manufacturing and design complexities, enabling faster, more powerful and more efficient products in smaller sizes. This is the first consumer product that takes advantage of EMIB.Intel has also developed unique software drivers and interfaces for the discrete GPU to coordinate information among all package elements, managing temperature and power delivery along with allowing system designers to optimize the power sharing between processor and graphics for specific tasks like performance gaming. Through this collaboration, Intel and AMD are aiming to create a chip that will enable thinner, lighter, more powerful mobile devices through a better combination of performance-level processors and discrete graphics in a smaller form factor. The end goal is to create laptops that are thin and portable, but still powerful

Qualcomm Accuses Apple of Helping Intel Using Qualcomm Software

Qualcomm on Wednesday filed yet another lawsuit against Apple, this time accusing the company of breaching software licensing terms and using Qualcomm code to help Intel, reports Bloomberg. According to Qualcomm, Apple breached a contract that dictates the use of software that's designed to make Qualcomm chips work with other iPhone components. Qualcomm also believes Apple may have used its access to that software to help Intel with its own modem chip development. Since 2016, Apple has been using LTE chips from both Intel and Qualcomm in an effort to diversify its supply chain and move some production away from Qualcomm. The iPhone 7, 7 Plus, 8, and 8 Plus all use a mix of Qualcomm and Intel chips. In light of the ongoing legal battle with Qualcomm, Apple is said to be considering eliminating Qualcomm chips from its devices all together, instead adopting chips from Intel and possibly MediaTek. Rumors suggest Qualcomm has been withholding software from Apple that Apple needs to test prototype devices for next year, forcing Apple's hand. Qualcomm and Apple have been involved in an escalating legal fight since the beginning of the year after Apple sued Qualcomm for $1 billion. Apple has accused Qualcomm of charging unfair royalties for "technologies they have nothing to do with" and failing to pay for quarterly rebates. Apple has since stopped paying royalties to Qualcomm until new licensing fees have been worked out, as have Apple suppliers, significantly impacting Qualcomm's profits. Qualcomm has since levied several lawsuits against Apple, accusing the

iMac Pros With Custom Xeon Chips Possibly Appear on Geekbench Ahead of December Launch

While the iMac Pro doesn't launch for another six weeks or so, possible benchmarks for the computer may have already surfaced on Geekbench. The results provide us with an early look at just how powerful Apple's $4,999-and-up desktop workstation will be when it is released in December. Interestingly, the iMac Pro models benchmarked appear to have custom, downclocked Xeon chips that Intel hasn't publicly announced yet. There is a benchmark result for a model with a 3.2GHz 8-core Xeon W-2140B processor, while a third listing exists for a model with a 3.0GHz 10-core Xeon W-2150B chip. All of the models are identified as "AAPJ1371,1," and unlike other Xeon chips, the processors have a "B" suffix. A few of the benchmark results are from late August, while the rest are from October. MacRumors spoke with Geekbench founder John Poole, who speculated that the iMac Pro may require chips with lower thermal design power, and thus lower frequencies, due to its all-in-one form factor. He noted that the other chips in the Xeon Processor W family have relatively high TDPs of up to 140W. The multi-core Geekbench score for the 8-core model averages out to 23,536, which is the highest performance of any iMac ever. It's nearly 22 percent faster than the latest 5K iMac equipped with a maxed-out 4.2GHz quad-core Core i7 processor, which has an average multi-core score of 19,336. The higher-end 10-core iMac Pro has a multi-core score of 35,917, which is roughly 41 percent faster than the latest Mac Pro maxed out with a 2.7GHz 12-core Xeon E5 processor. Even its single-core

iPhone 8 Shows Modest Improvements in Cellular Network Bandwidth Tests

With a number of iPhone 8 and 8 Plus devices now in the hands of users, Ookla's network benchmarking suite Speedtest.net has been able to gather data on how the latest iPhones are performing compared to previous-generation models and has shared details with PCMag. Based on data collected by Ookla, improvements appear to be around the 10 percent mark for most users, but users in Australia could expect up to nearly 25 percent faster speeds thanks to their network structure. Those users can expect up to the full 80 MHz carrier aggregation bandwidth in the phone due to Telestra's use of the appropriate bands. iPhone 8 download speeds compared to previous generations Beyond speed comparisons to previous-generation iPhones, PCMag also compares the iPhone 8's cellular architecture to competing phones, such as the Galaxy S8.The iPhone 8 is missing one of the components needed for gigabit LTE, or LTE category 16, in the US. The Qualcomm X16 modem can do Category 16, as we've seen on the Galaxy S8 and Moto Z2 Force. The phone supports 256QAM encoding and 4x carrier aggregation to 80MHz of spectrum, but not 4x4 MIMO antennas, which would improve both speed and signal strength. In theory, that would make this an 800Mbps phone, also known as LTE category 15.The lack of 4x4 MIMO antennas is something we touched on at MacRumors on Tuesday. While the Qualcomm and Intel modems in the new iPhones are likely more power efficient, the cellular front-end and back-end supporting them are largely unchanged in structure from the iPhone 7 models. The article goes on to point out can that
