Samsung Galaxy S4 GPU specs: PowerVR and Adreno Ahoy

Depending on where you buy the Samsung Galaxy S4, you will either get an Imagination PowerVR SGX544MP3 GPU solution (clocked at 533MHz and capable of reaching 51.2GFLOPS) found in the international version of the handset (as part of the Exynos 5410 SoC) or the Adreno 320 in the US (inside the Qualcomm Snapdragon 600).

The latter is found in the S4 Pro and S4 Prime series and according to Qualcomm, is four times faster than the Adreno 225 which is found in all the high-end Windows Phone 8 smartphones and in the Blackberry Z10. The Adreno 320 supports DirectX 9.0 L3, OpenGL ES 3.0, 2.1 and 1.1 plus OpenCL 1.2.

As for the PowerVR solution, it has the same level of API support as the 320. It is used in a number of smartphones like the Lenovo K900 (based on the Clovertrail+ Atom Z2580), the Samsung Galaxy Premier and tablets like the Amazon Kindle Fire HD.

It is interesting to note that previous Exynos SoC, bar the original Exynos 3 Single (otherwise known as the S5PC110, a chip which powered the original Samsung Galaxy S) used ARM’s T-400 GPU solutions at various clock speeds. Even the Exynos 5 Dual which is used in the Nexus 10 is powered by the ARM Mali-T604, a quad core solution which provides with a whopping 72.5GFLOPS of processing power.

So why would Samsung swap ARM for PowerVR? There's no doubt that Imagination Technologies has been working extremely hard to woe Samsung way from ARM and the fact that Korean company mentions that the graphics performance of the Exynos 5 Octa is more than twice that of the Exynos 4 series is a tribute to the PowerVR family. When it comes to raw performance though as measured in GFLOPS, both ARM's Midgard and the SGX544MP3 seem to be quite similar so it is likely that power consumption (and perhaps costs) is what appears to be the defining factor.
