Imagination's PowerVR GX6650: Competition for Mobile Kepler
by Anand Lal Shimpi on February 24, 2014 3:27 AM ESTRyan touched on this in his excellent deep dive on Imagination's PowerVR Series 6XT GPU architecture earlier today, but I wanted to specifically call out the new high-end from IMG that was announced back in January. Pictured above is a high-level block diagram of the new PowerVR GX6650, this is IMG's answer to NVIDIA's mobile Kepler/Tegra K1.
Below I've included a modified version of Ryan's comparison table from his architecture piece:
GPU Specification Comparison | |||||||
NVIDIA K1 | Imagination PowerVR GX6650 | Imagination PowerVR G6430 | Imagination PowerVR G6230 | ||||
FP32 ALUs | 192 | 192 | 128 | 64 | |||
FP32 FLOPs | 384 | 384 | 256 | 128 | |||
Pixels/Clock (ROPs) | 4 | 12 | 8 | 4 | |||
Texels/Clock | 8 | 12 | 8 | 4 | |||
GFLOPS @ 300MHz | 115.2 GFLOPS | 115.2 GFLOPS | 76.8 GFLOPS | 38.4 GFLOPS | |||
Architecture | Kepler | Rogue (Series 6XT) | Rogue (Series 6) | Rogue (Series 6) |
I tossed in the Series 6 PowerVR G6430 as a comparison point. The G6430 is the GPU in the iPad Air/iPad mini with Retina Display/iPhone 5s. If Apple decides to go all out with a GPU upgrade on its next-generation iPad Air (A8/A8X silicon perhaps?), the GX6650 would likely be the IP to use.
