A9X in 9.7-Inch iPad Pro is Underclocked Compared to 12.9-inch iPad Pro

The new 9.7-inch iPad Pro adopts the same powerful dual-core 64-bit A9X chip that was first introduced in the 12.9-inch iPad Pro, but the two tablets are not on par when it comes to performance. Based on information on Apple's website, it appears the A9X in the 9.7-inch iPad Pro is slightly underclocked compared to the A9X in the 12.9-inch iPad Pro (via AppleInsider). On its iPad comparison page, Apple lists the specs of the A9X in both of the iPad Pros, comparing them to the A7 chip in the iPad Air, iPad mini 2/3, and iPhone 5s. The 12.9-inch iPad Pro lists a 2.5x faster CPU and 5x faster graphics, while the 9.7-inch iPad Pro lists a 2.4x faster CPU and 4.3x faster graphics. Apple has a history of underclocking the chips used in smaller devices. The iPad mini 2 and the iPad Air both used the same A7 chip, but while the iPad Air clocked in at 1.4GHz, the iPad mini 2 ran at 1.3GHz. It's likely Apple is underclocking the A9X chip in the 9.7-inch iPad Pro due to its smaller body, which may be unable to dissipate heat as well as the larger 12.9-inch iPad Pro, The performance difference between the two tablets is likely to be unnoticeable in real world conditions, and even underclocked, the 9.7-inch iPad Pro is offering some significant performance improvements over the 9.7-inch iPad Air 2. Aside from the slightly lower clock speed, the 9.7-inch iPad Pro has several features that set it above the 12.9-inch iPad Pro, including a 12-megapixel camera with a rear flash and a new True Tone display feature that adjusts the screen's temperature based on ambient lighting.

iPad Pro Tidbits: A9X Outperforms MacBook, Apple Pencil is Weighted, T-Mobile Financing and More

Apple released the iPad Pro on the Apple Online Store and at select Apple Retail Stores and resellers earlier today, and we have rounded up some interesting facts and news announcements surrounding the 12.9-inch tablet. iPad Pro Delivers Notebook-Level Performance Geekbench results show that the iPad Pro's A9X processor is a dual-core chip running at about 2.25 GHz, as reported by Ars Technica. The A9X chip had a 3,233 single-core score and 5,498 multi-score score in browser-based CPU tests, outperforming the iPad Air 2 and other recent iPhones and iPads by a significant margin. iPad Pro also outperformed the 12-inch Retina MacBook, equipped with an Intel Core M dual-core processor clocked at 1.1 to 1.2 GHz, but the A9X chip's CPU performance falls short of devices like the 2015 MacBook Air and Surface Pro 4 with Intel's latest Broadwell or Skylake U-series processors. Ars Technica also shared iPad Pro CPU performance results The iPad Pro's GPU performance is much more impressive, with GFXBench OpenGL test results showing the A9X chip outperformed the 2015 15" Retina MacBook Pro with Intel Iris 5200 integrated graphics, in addition to the 12-inch MacBook, 2015 MacBook Air, 2015 13" Retina MacBook Pro, Surface Pro 4 and all recent iPads.We’re looking at MacBook Air-class CPU performance and MacBook Pro-class GPU performance, so the iPad Pro ought to be able to handle more multitasking features with aplomb as Apple sees fit to add them. Professional 3D apps like AutoCAD and the Complete Anatomy app Apple showed off in September all seem to run just fine, too.A

iPad Pro Features Improved Storage Controller for Desktop-Class Performance

Apple's new iPad Pro is powered by a 64-bit A9X processor that delivers up to 1.6 times faster performance over the iPad Air 2, with up to twice as fast graphics. Apple also says the tablet is faster than 80% of portable PCs shipped in the last 12 months. Apple's website notes the underlying technology behind the iPad Pro's desktop-class performance is a new storage controller that increases read and write speeds so that large files, such as 4K videos or RAW photos imported from an HD camera, can be opened much quicker (via AppleInsider).The A9X chip is capable of processing data so quickly, it demanded a new memory architecture. iPad Pro features a revamped storage controller that helps deliver performance better than some desktop computers. This increases read and write speeds, so you can quickly open even the largest files. Like the big 4K movie you just edited or all the RAW images you imported from your HD camera.iPad Pro launches in November in Silver, Space Gray and Gold, starting at $799 for a 32GB Wi-Fi only model. A 128GB Wi-Fi only model will cost $949 and a Wi-Fi + LTE 128GB model will cost $1,079. A new Apple Pencil and Smart Keyboard will launch alongside the tablet for $99 and $169
