Mobile SoCs claimed numbers are hard to take at face value. For one, I'm 98% sure that's FP16 flops. For another, basically all SoCs in shipping devices throttle under load, so efficiency is hard to determine from unrelated peak performance and max power draw numbers.
Anyway, Cortex-A15 is capable of 8 flops per cycle per core which puts it pretty good in theoretical efficiency for its likely power draw at current clocks.
- sklogic 12y agoNo, these are fair 32bit GFLOPs. No, VC4 do not throttle, power figures are given for the real max load. And I never managed to get close to 8 ins per cycle on A15, but, for example, an FFT implementation on VC4 is pretty close to a theoretical performance limit. And a fully loaded 4-core A15 will draw far above 500mW anyway.
