At least it seems so to me. My last 1 and 2 core systems had a TDP of 65 
and 105W. Now it's 130W, the next gen have 12 cores and 130W TDP.

So I currently have 8 CPU cores and 480 GPU cores. Unfortunately many 
open source applications don't use the GPU (maybe OpenGL 1.0 but usually 
software rendering. The gpu accelerated desktops are still buggy and 
crash prone) and are single threaded. Even some heavier tasks like video 
encoding uses cores very inefficiently. Would MPI help?
