GPU achieves 800GFLOPS (FP32) or 1.6TFLOPS (FP16)
At last year’s Mobile World Congress, Imagination Technologies unveiled PowerVR GX6650, a high-end Series6XT GPU for flagship devices. Today, focus has shifted to PowerVR GT7900, the highest performing GPU from ImgTec's Series7XT family. PowerVR GT7900 is a GPU designed for ultimate performance in embedded applications; this design takes everything from its predecessor and turns the dial to 11.
Including 512 ALU cores, the GPU delivers up to 800GFLOPS (FP32) or 1.6TFLOPS (FP16) graphics and compute performance at 800MHz (16nm FinFET+). As an idea of how it stacks up against the competition, a Kepler-based GeForce GT 730M from NVIDIA delivers about 550 GFLOPS (FP32) at a comparable frequency.
Unique advantages of PowerVR GT7900 include a superior FP16 ALU and fillrate performance for low power computing at high resolution, support for OpenGL ES 3.1 + AEP (Android Extension Pack), including hardware tessellation (some competitors offer software-only support) and ASTC LDR and HDR texture compression standards, multi-domain hardware virtualisation at the GPU + CPU level (all competing solutions are CPU-only) supporting multiple operating systems running in parallel on a single platform.
Superior performance efficiency is complemented by PowerGearing: a mechanism that defines power islands which can be dynamically controlled to reduce thermal throttling.
