Hi,
I love TPU reviews on GPUs but I've been thinking recently that there's one particular testing mode which is worth reporting on (I've never seen other reviewers doing it).
Let me describe it:
Take a not very recent game (WoW: Mists of Pandaria), which has a high frame rate even on mid level GPUs (> 100FPS @FullHD resolution), cap the game to 60 frames per second (e.g. using VSync), then check how much energy 1) the GPU consumes 2) the whole PC (barring the display) consumes.
This test will reveal how power efficient different GPUs are.
The rationale behind this request is that many people often overlook one very important consideration: when you replace a slower GPU with a faster GPU (more power hungry), not only your new GPU consumes more energy, your whole system starts to consume more energy because the CPU has to calculate more data (more FPS = more physics, AI, etc.)
Thank you.
