Samsung has announced during CES its Exynos 5 Octa SoC featuring four ARM Cortex A7s and four ARM Cortex A15s. Unusually absent from the announcement was any mention of the Exynos 5 Octa’s GPU configuration. Given that the Exynos 5 Dual featured an ARM Mali-T604 GPU, we only assumed that the 4/8-core version would do the same. Based on multiple sources, we’re now fairly confident in reporting that the with the Exynos 5 Octa Samsung included a PowerVR SGX 544MP3 GPU running at up to 533MHz.
The PowerVR SGX 544 is a lot like the 543 used in Apple’s A5/A5X, however with the addition of DirectX 10 class texturing hardware and 2x faster triangle setup. There are no changes to the unified shader ALU count. Taking into account the very aggressive max GPU frequency, peak graphics performance of the Exynos 5 Octa should be between Apple’s A5X and the A6X (assuming Samsung’s memory interface is just as efficient as Apple’s) :
It’s good to see continued focus on GPU performance by the major SoC vendors, although I’d like to see a device ship with something faster than Apple’s highest end iPad. At the show we heard that we might see this happen in the form of an announcement in 2013, with a shipping device in 2014.
At the 2012 Embedded Technology Conference and Exhibition (ET), Imagination has announced its latest member of the Series6 “Rogue” family of GPUs – the PowerVR G6630.
The G6630 features one core containing six shading clusters, which according to Imagination delivers “blisteringly fast GPU compute capabilities”. It also supports some major APIs including OpenGL ES 3.0, OpenCL 1.x and even full WHQL-compliant DirectX 10.
Imagination points out that the PowerVR G6630 GPU achieves better linear compute scalability compared to its multi-core GPU rivals as it sports an unified shader array architecture. It all sounds fine and dandy, but I’d like to see Imagination put money where their mouth is and release it as soon as possible so that we can pit it against the Adreno 320.
That, however, will take at least a good six months or more in order for chip manufacturers like ST-Ericsson and Texas Instruments to release their latest SoCs.
Ever since the iPhone 5 announcement, it’s been a mystery what exactly makes the new A6 processor innovative. We’ve already seen its impressive performance benchmarked, but now we get to take a closer look at the architecture itself.
A new microscopic examination of the chip not only shows the custom dual ARM cores side-by-side, but also lets us see the unique triple-GPU layout.
What does this mean? Simply put, Apple have invested in customizing their own chipset, which results in an optimized architecture capable of producing better results without having to rely on higher clock speeds.
This extra customization process in the face of off-the-shelf solutions like the Cortex-A15 shows some great innovation from the Cupertino-based tech giant
