Apple A6 investigation shows highly customized dual-core, triple-GPU layout

Apple A6 teardown confirms highly customized dualcore, tripleGPU layout

There’s been a significant mystery lingering around the A6 processor found in the iPhone 5, even as it became clearer that Apple was veering further than usual from the basic ARM formula. A microscope-level inspection by Chipworks and iFixit is at last identifying the key elements of the 32nm, Samsung-assembled chip and revealing just how far it strays from the beaten path. The examination confirms earlier suspicions of a dual-core design with triple-core graphics — it’s how that design is shaped that makes the difference. Apple chose to lay out the two processor cores by hand rather than let a computer do the work, as most ARM partners do. The procedure is expensive and slow, but also gives the A6 a better-optimized design; it explains why the chip is noticeably faster than much of its competition without needing the brute force approaches of higher clock speeds or extra cores. Some mysteries remain, such as the exact PowerVR graphics that are at work, but it’s evident Apple now has the design talent and resources to speed up mobile devices on its own terms rather than wait for off-the-shelf layouts like the Cortex-A15.

Globalfoundries unveils 14nm-XM chip architecture, vows up to a 60 percent jump in battery life

Globalfoundries unveils14nmXM chip architecture, vows as much as 60 percent more battery life

Globalfoundries wants to show that it can play the 3D transistor game as well as Intel. Its newly unveiled 14nm-XM (Extreme Mobility) modular architecture uses the inherently low-voltage, low-leak nature of the foundry’s FinFET layout, along with a few traces of its still-in-development 20nm process, to build a 14-nanometer chip with all the size and power savings that usually come from a die shrink. Compared to the larger processors with flat transistors that we’re used to, the new technique is poised to offer between 40 to 60 percent better battery life, all else being equal — a huge help when even those devices built on a 28nm Snapdragon S4 can struggle to make it through a full day on a charge. To no one’s shock, Globalfoundries is focusing its energy on getting 14nm-XM into the ARM-based processors that could use the energy savings the most. It will be some time before you find that extra-dimensional technology sitting in your phone or tablet, though. Just as Intel doesn’t expect to reach those miniscule sizes until 2013, Globalfoundries expects its first working 14nm silicon to arrive the same year. That could leave a long wait between test production runs and having a finished product in your hands.

Samsung Exynos 5 Dual white paper confirms new high marks for mobile graphics, memory performance

Our SIGGRAPH demo of the ARM Mali-T604 GPU gave a brief preview of Samsung’s upcoming Exynos 5 Dual CPU, but now all the details of the company’s next great processor are ready for us to view. Other than that GPU which includes support for up to WQXGA (2,560 x 1,600) resolutions — perfect for the 11.8-inch P10 mentioned in court filings — and much more, the white paper uncovered by Android Authority also mentions support for features like Wi-Fi Display, high bandwidth LPDDR3 RAM running at up to 800MHz with a bandwidth of 12.8GBps, USB 3.0 and SATA III. It also claims the horsepower to decode 1080p video at 60fps in pretty much any codec, stereoscopic 3D plus handle graphics APIs like OpenGL ES 3.0 and OpenCL 1.1. All of this is comes courtesy of a dual-core 1.7GHz ARM Cortex-A15 CPU built on the company’s 32nm High-K Metal Gate process and Panel Self Refresh technology that avoids changing pixels unnecessarily to reduce power consumption. There’s plenty of other buzzwords and benchmarks floating around in the PDF, you can check them out in the PDF linked below or just sit back and see what tablets and phones arrive with one of these — or the competition from Qualcomm’s S4 and NVIDIA’s Tegra — inside starting later this year.
