At CES, Samsung announced 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):

Mobile SoC GPU Comparison
  PowerVR SGX 543MP2 PowerVR SGX 543MP4 PowerVR SGX 544MP3 PowerVR SGX 554MP4
Used In A5 A5X Exynos 5 Octa A6X
SIMD Name USSE2 USSE2 USSE2 USSE2
# of SIMDs 8 16 12 32
MADs per SIMD 4 4 4 4
Total MADs 32 64 48 128
GFLOPS @ Shipping Frequency 16.0 GFLOPS 32.0 GFLOPS 51.1 GFLOPS 71.6 GFLOPS

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.

    Here is my calculation, what is wrong?
    533x10^6 * 4 cores * 4 SIMD/core * 4 ALU/SIMD * 2 Flops/ALU = 68.2 GFLOPS

    Exynos 5 Octa does not support OpenGL ES 3.0 , Is it matter or not? Reply

    the gpu of this phone has twice the graphic performance of the Iphone 5, which the gpu runs at 267MHz, then the gpu of the Galaxy S4 I9500 running at 533MHz, already that one core of the SGX544 gpu, at 200MHz has 7.2 GFLOPS of compute performance, 3 cores of SGX544 at 533MHz have 57.6 GFLOPS, not 51.1 GFLOPS, like the specialists of tech site Anandtech wrote.
