Imagination's PowerVR GX6650: Competition for Mobile Keplerby Anand Lal Shimpi on February 24, 2014 3:27 AM EST
Ryan 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|
|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.
