MediaTek unveils quad-core MT8125 processor for budget tablets

Posted on by

MediaTek processor

MediaTek told us to only expect its tablet-focused SoC in the summer, but it's clearly something of a keener: we're already looking at the part today. The new MT8125 builds on the familiar formula of a quad-core Cortex-A7 processor and PowerVR Series5XT graphics, with most of the improvement coming from a higher 1.5GHz clock speed. That extra grunt helps the chip handle up to a 1,920 x 1,200 display on top of earlier support for 13MP cameras and 1080p videos. Focusing on tablets gives MediaTek some freedom in configurations, too -- it can offer the SoC with basic EDGE cellular data, full HSPA+ or WiFi alone. Customers won't have to wait long to try the MT8125 when tablets like Lenovo's IdeaTab S6000 series should be using it now, although there's no word on how much of that hardware will reach the US.

Samsung’s next-gen Exynos 5 Octa rumored to have only current-gen PowerVR graphics

Samsung Exynos Octa chip rumored to use lastgen PowerVR graphics

There's nothing we can concretely do or say about the Exynos 5 Octa until it's in a device and in our hands. It's all just educated guesswork in the meantime, but that happens to be something AnandTech is rather good at. That site has reached the conclusion, based on "numerous sources," that the Octa probably uses a PowerVR 544MP3 GPU clocked at 533MHz. If true, this implies that the ARM Mali T-604 used in Exynos Dual devices like the Sammy Chromebook somehow couldn't meet Octa's needs, and that the higher-specced T-658 perhaps wasn't ready. It also suggests that Octa's graphical and GPU compute performance might lie somewhere between that of the third-gen iPad (A5X) and the fourth-gen (A6X). Frankly, a newer GPU would have been more exciting, especially given the appearance of PowerVR Series6 at CES, but big.LITTLE should still give us plenty to talk about when the new eight-core chip finally arrives.

Imagination Technologies’ PowerVR Series 6 mobile GPU debuts at CES, we go eyes-on

Imagination Technologies' PowerVR Series 6 mobile GPU debuts at CES, we go eyeson

Last week, Imagination Technologies gave us a glimpse of its next-gen PowerVR Series 6 mobile GPU and its prowess with OpenGL ES 3.0. That demo didn't showcase Series 6's full potential, as the company could only let us see a test chip on an FPGA board that could deliver only 1 GB/s of bandwidth -- one tenth of the GPUs performance capability. Now that Imagination Technologies' first Series 6 partner, LG, has given the go ahead, the time has come to see what Series 6 can really do on an optimized board destined for an HDTV.

In addition to the Series 6, the company also demoed an older Series 5XT GPU that's been upgraded with some recently released API extensions. Those APIs are meant to breathe new life into Imagination Technologies' older GPUs and give them some of the rendering features found in the Series 6. Interest piqued? You can see the GPUs do their thing in our demo video after the break.

OpenCL mod for the Kindle Fire HD reveals untapped graphics potential (hands-on video)

Posted on by

If a Kindle Fire HD could run OpenCL accelerated graphics, it'd look like this handson video

As neat as the Kindle Fire HD already is, just a few dinky tweaks could turn it into so much more -- a platform for true physics-based gaming, for example, or even for surprisingly fast photo manipulation. How come? Because both the 8.9-inch and 7-inch versions of the Android-based slate come with a graphics engine that can handle OpenCL acceleration. It certainly won't work out of the box, but Amazon has been working quietly with Imagination Technologies -- the folks behind the tablet's PowerVR GPU -- to try it out. The demo after the break is subtle, perhaps, but it's fluid, detailed and goes far beyond anything that a stock device can achieve. It also proves that, in certain circumstances, OpenCL has the power to boost frame rates by 50 percent while simultaneously lowering power consumption by the same proportion. Read on for more.

PowerVR Series6 mobile GPUs are almost here, we go eyes-on with a test chip (video)

PowerVR Series 6 mobile GPUs are almost here, we go handson with a test chip video

Imagination Technologies is on a high right now. Throughout 2012, the company's PowerVR graphics processors continued to monopolize the iPhone and iPad as well as appearing in (late 2011) Android flagships, the PlayStation Vita and even the first Clover Trail-powered Windows 8 tablets. But you know what? That's old news, because all those devices run current-gen PowerVR Series5 silicon. Most new top-end devices in 2013 and 2014 will either contain the latest Mali GPUs from rival ARM, or they'll pack PowerVR Series6, aka Rogue. This latter chip is currently being developed by at least eight different smartphone and tablet manufacturers and is expected to make a good bit of noise at CES next week.

But who's going to wait that long if they don't absolutely have to? To get a fuller understanding of what awaits us in the coming weeks and months, we scoped out a Rogue test chip at Imagination's sparkly new HQ just outside of London, UK. The test silicon doesn't represent the true power of Series6 because it's running on an FPGA board that severely limits its bandwidth, but it's still able to show off one crucial advantage: namely the ability to run OpenGL ES 3.0 games and apps. This API is all about improving mobile graphics through making smarter use of GPU compute, without annoying the battery, and the three demos after the break show just how it pulls that off.

Allwinner throws A20 dual-core and A31-quad-core processors into ARM fray

Allwinner throws A20 dualcore and A31quadcore processors into ARM fray

Whimsically monikered Chinese chip-maker Allwinner has added a pair of ARM Cortex-A7 processors to its lineup supporting Android 4.2 or higher systems. The A20 is a dual-core design with 512KB L2 cache, dual-core Mali 400 graphics and 2160p HD video playback support, while the quad-core A31 packs a 1MB cache, PowerVR SGX 544 graphics and UHDTV (4k) video decoding talents. The A20 is pin compatible with its Linux-hobbyist favorite sibling, the A10 -- meaning devices such as the MK802 mini-PC using that chip could likely be upgraded by manufacturers on the cheap. However, the more powerful A31 seems destined for higher-end Android or Windows RT devices only, considering its beefier PowerVR graphics. On top of the extra zip, licensor Imagination Technologies keeps its source code cards close to the chest -- likely ruling out Linux for that chip.

Imagination Technologies snaps up CPU designer MIPS in an attempt to wrestle ARM

Imagination Technologies snaps up CPU designer MIPS in an attempt to wrestle ARM

Looks like we can kiss goodbye to any lingering politeness in the rivalry between these two UK chip houses, because the smaller one has just embarked on a cheeky expansion. Having been known mainly for its PowerVR graphics processors, not least in many Apple products, Imagination Tech could potentially push into the CPU arena too, through its $60 million acquisition of MIPS Technologies. Just Like ARM, MIPS designs low-power RISC processors for consumer electronics, but it has generally focused on smaller chips for devices like routers and TVs rather than smartphones and tablets. In addition to a portfolio of 82 exclusive patents, a squad of 160 MIPS engineers will now be transplanted to Imagination, where they'll no doubt be debriefed and reassigned to conquering the world. Meanwhile, in some sort of flanking move, ARM has paid a far higher sum of $170 million to gain access to a number of other MIPS patents.

Late 2012 iPad carries new PowerVR SGX 554MP4 graphics, muscles ahead in video speed

iPad 4thgeneration found carrying new PowerVR SGX 554MP4 graphics, muscles ahead of all comers

It's well established that the A6X chip in the fourth-generation iPad is about twice as fast as its predecessor in pure number crunching, but how about those reportedly doubled graphics amid some increasingly fierce competition? Thanks to some help from Kishonti, AnandTech has learned that Apple may still have an ace up its sleeve. The new tablet carries a new, quad-core PowerVR SGX554MP4 with twice the raw potential as the already quick 543MP4 graphics in the A5X. While that doesn't always lead to a literal doubling of 3D performance, it unambiguously puts the new new iPad on top in GLBenchmark, with even the imminent Nexus 10's new Mali-T604 video left in the middle of a large pack. We're somewhat surprised when the Samsung-made Nexus is using a brand new chip architecture that many had thought would represent a fundamental leap in speed. Visuals aren't the only factors in buying tablets, so take the results with the appropriate grains of salt; if gaming or sheer responsiveness matters most, however, there's now a clear frontrunner.

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.
