I'd love to see a description of a Samsung 64-bit ARM SoC, a new mobile graphics benchmark and a paper from an Apple engineer this fall.
I’d also like to see a paper describing a benchmark that can clearly compare the performance per watt of the various mobile graphics chips running the just as varied array of today’s mobile graphics APIs.
Imagination Tech holds sway in the market here, but ARM’s Mali is gaining traction. Nvidia and Qualcomm have strong positions as do a couple other merchant providers.
The architectures are so diverse experts warn you cannot just count cores to determine who is best. But it’s the APIs that really muddy the water here.
There’s OpenCL from Khronos, Cuda from Nvidia, AMP from Microsoft, River Trail from Intel, Aparapi from AMD, Renderscript from Google and OpenACC a variant of OpenMP. Too many ports in a storm for me!
Along a similar line, I’d love to see a paper that provides metrics for different approaches to dynamic voltage and frequency scaling. Intel CPUs have been doing this forever. Nvidia was first to show it in the ARM camp with its Tegra 3. More recently, ARM rolled out its big.little approach for doing it across multiple chips.
I’d love to see a paper compare the MHz per joule of Samsung Octa to Tegra 3 to say, Intel’s upcoming 22nm Bay Trail SoC with the Silvermont Atom core. That would indeed be a cutting edge analysis.
