Apple Considering Adopting AMD Processors for Upcoming Macs?

Friday April 16, 2010 10:12 am PDT by Eric Slivka

AppleInsider reports that Apple and AMD are in "advanced discussions" to bring the chipmaker's processors to upcoming Macs, potentially breaking the exclusive relationship Apple has held with Intel since moving away from PowerPC processors in 2006.

Representatives for the Sunnyvale, Calif.-based AMD have recently been seen on Apple's Commuter Coach buses, and executives for the chipmaker have been spotted on their way out of meetings with members of Apple's top brass, according to people familiar with the matter.

The meetings have reportedly included briefings by AMD that have since enabled Apple to begin working with AMD processors in its labs as part of an initiative to position the chips inside some of the company's forthcoming products.

According to the report, Apple is looking at using AMD's chips in its Mac lines, seeking to increase its flexibility for sourcing chips going forward. In particular, recent shortages of new notebook chips from Intel that reportedly led to a delay in the release of new MacBook Pros and licensing issues that have hindered graphics chipmaker NVIDIA's ability to work with Intel's processors have reportedly caused Apple to adopt a growing sense of dissatisfaction with Intel.

AMD's chip offerings are currently considered subpar when compared to those from Intel, but the report suggests that lower pricing and the ability to bundle AMD processors with ATI graphics chips (ATI is owned by AMD) as possible reasons for bringing a switch under consideration. In addition, Apple may have inside knowledge of forthcoming offerings from AMD that could make the chipmaker more competitive with Intel, or AMD might be more willing to offer custom solutions for Apple than Intel currently is. Finally, the report concedes that the talks could simply be a leveraging tool to assist Apple in its dealings with Intel.

Apple in advanced discussions to adopt AMD chips

Intel has served as Apple's sole source for the microprocessors used in its notebook and desktop personal computers since the company began its transition away from PowerPC in 2006, but that may soon change given the company's recent talks with Intel's chief CPU rival Advanced Micro Devices.

Representatives for the Sunnyvale, Calif.-based AMD have recently been seen on Apple's Commuter Coach buses, and executives for the chipmaker have been spotted on their way out of meetings with members of Apple's top brass, according to people familiar with the matter.

The meetings have reportedly included briefings by AMD that have since enabled Apple to begin working with AMD processors in its labs as part of an initiative to position the chips inside some of the company's forthcoming products. While AMD offers a variety of embedded processors, Apple is believed to be investigating the chipmaker's workstation and notebook class CPUs.

It is believed that Apple is working with AMD to expand its potential sources for CPUs in order to increase its flexibility and broaden its competitive options, but also likely in response to problems it has encountered with Intel. These issues include limited availability of new processors (which is rumored to have slowed Apple's notebook refreshes) as well as new chipset designs imposed by Intel that have blocked the Mac maker's plans to continue a partnership with NVidia to deliver a standardized chipset for use with its Intel processors across all of its consumer computer offerings.

Intel has fought against Nvidia to close the market for alternative chipsets for use with its CPUs, which resulted this week in Apple being forced to use Intel's own limited integrated graphics chips inside its new MacBook Pros instead of using more capable parts from Nvidia.

Why Apple hasn't used AMD CPUs before

When Apple first announced its plans to migrate to Intel CPUs back in 2005, many observers questioned why the company wasn't also using AMD's compatible processors as a secondary option. AMD's chips at the time were considered more powerful and often cheaper than Intel's flagship offerings, including the Pentium IV. However, Apple was privy to information about Intel's roadmap, and was primarily interested in the company's new Core line of fast, yet energy efficient designs suitable for use in its notebooks.

AMD's edge in CPUs in the first half of the 2000 was blown away by Intel's new Core family, which came to market just as Apple was making its transition. AMD currently offers few advantages in terms of performance or efficiency, but does offer significantly lower component pricing than Intel. AMD also owns ATI, which produces graphics chips Apple continues to use in some of its models.. This suggests the possibility that Apple could deliver an integrated package of AMD and ATI components that delivered respectable performance and great graphics performance at a lower price than Intel's.

Having multiple sources of CPUs would enable Apple to use the best parts available from each supplier, similar to how the company has worked with both ATI and NVidia to offer competing options in Mac graphics adapters. With the dramatic growth Apple has experienced in its Mac sales over the past half decade, it may now make sense for the company to offer a wider array of competitive CPU options to target a broader range of price points and performance needs.

Reasons for new interest in AMD

Given word of the ongoing discussions and briefings, Apple may also now have access to new information about competitive products AMD has in the pipeline. The company may also have original design specifications that AMD may be more willing to adopt than Intel just to obtain Apple's high profile business. Similar to how Apple optimized the A4 ARM SoC used by iPad, Apple may be planning to develop customized x64 CPUs for its Macs that AMD could be interested in building specifically for use by Apple.

The talks with AMD could also be part of a competitive leveraging strategy to keep Intel interested in retaining Apple's core business, similar to how the company has been rumored to be discussing plans to use Microsoft's Bing search engine in preference to Google's on the iPhone.

At the same time, while AMD has historically trailed Intel's performance and efficiency in CPUs, particularly in the mobile computing space, the company's acquisition of ATI gives it far more powerful GPU technology than Intel currently has.

Both companies are rushing to fuse CPU and GPU cores into a SoC-style part for notebooks (similar to the design used by ARM SoCs in embedded applications such as the iPhone and iPad), as Intel has already done in the latest generation of MacBook Pros, pairing its integrated graphics with the Arrandale Core i5 or i7 processor.

AMD could offer very competitive options for Apple's future notebooks, particularly given the Mac maker's focus on graphics performance and its related GPU technologies, including Grand Central Dispatch and OpenCL.

If AMD can deliver 80% of the CPU performance of Intel at 60% of the cost, and add significantly better GPU performance and sophistication, it would not be surprising to see Apple working to adopt the company's parts broadly across its Mac lineup within the next year or two.
