Is there any point in actually damning FP64 this hard anymore? There is no reason, imo, for a modern GPU to get worse than 1/3rd performance on FP64 over FP32.

Side note: Non-Quadro/Tesla "professional" GeForces have FP64 performance specifically locked out, and AMD has started also doing this with GCN-era chips.

My focus was on mobile, not desktop GPUs. However, I've noticed that energy and area efficiency are starting to become more relevant in desktop too.

At the end of the day, I guess it's all about finding the right balance for your target application.
