I’m always very confused when it comes to comparing GPUs in different SoCs, and I could not really find comparisons on the web, so I’m going to give it a try even though, as you’re going to find out, it’s actually quite a challenge.
There are mainly 4 companies that provide GPUs: ARM, Imagination Technologies, Vivante and Nvidia. Each company offers many different versions and flavors of their GPU as summarized below.
For each company the GPU are sorted by increasing processing power (e.g. Mali-T604 faster than Mali-400 MP, SGX535 faster than SGX531 etc…), and I did not include some older generations. As you can see there are many choices already, but you also need to take into account different number of cores (e.g. Mali-400 can have 1, 2 or 4 cores), process technology, and different operating frequencies chosen by SoC manufacturers for a given GPU, so that makes it even more complicated. That’s why I’m going to focus on one core for each GPU based on commonly used SoC: Rockchip RK3066 (Mali-400 MP4), Freescale i.MX6 (GC2000), AllWinner A31/ OMAP 5430 (SGX544 MP2), and Tegra 3 T30 (ULP Geforce).
Vivante has a product brief with a nice comparison table for their GPUs.
I’m going to use part for this table as base for performance comparison. For other GPUs, I’ll need to dig into the companies’ website:
|Mali-400 MP4||PowerVR SGX544MP2||GC2000||Tegra 3 GPU|
|Frequency||240 MHz to 400 MHz||532 MHz||528MHz (600 MHz shader)||520 MHz|
|44M Tri/s for 1 core @ 400 MHz
(Total: 172M Tri/s @ 400 MHz)
|35 M Tri/s per core @ 200 MHz
(Total: 744.8M Tri/s @ 532 MHz)
|100 M Tri/s (Freescale claims 200 M Tri/s in i.MX6, i.MX6 Reference Manual: 88 Mtri/s,… go figure)||–|
|1.6G Pix/s for 1 core @ 400 MHz||1 G Pix/s per core @ 200 MHz||1.25 G Pix/s (i.MX6 RM: 1.066G pixels/sec)||–|
|7.2 GFLOPS @ 200 MHz||136 GFLOPS||24 GFLOPS (21.6 GFLOPS
|7.2 GFLOPS @ 300MHz|
