The PowerVR G6430 from Imagination Technologies is a fast mobile graphics solution that is used in ARM SoCs like the Apple A7 (iPhone 5S). The chip is available since Q3/2013 and is one of the fastest solutions of its class at the time of the introduction.
Architecture and Performance
The GPU is based on the series 6 (Rogue) and integrates four clusters with two TMUs each and a scalar Unified Shader architecture. The chip does offer more than twice of the performance compared to the SGX543MP3 from the Apple A6, while maintaining the same clocks. The exact clock is not yet confirmed unequivocally, but it should be north of 400 MHz (results in more than 100 GFLOPS). A comparison with other mobile graphics solutions shows that the G6430 is just slightly behind the tablet version of the Adreno 330 and it is therefore the fastest GPU of its class at the time of the introduction. Even very demanding mobile games can be played without problems (as of 2013). Among others, the GPU supports OpenGL 3.x/4.x, OpenGL ES 3.0 as well as DirectX 10.
The manufacturer designed the PowerVR G6430 as a comparatively "wide" chip to achieve a high performance and a high energy efficiency at the same time. As a result, SoCs with the G6430 can also be used in smaller smartphones like the iPhone 5S. However, it does occupy a comparatively large area on the chip in return.
