Hang on, lets at least normalise that table...
GPU Alternative Performance..2.3 PFlop/s............... 2.3 PFlop/s
Cores................................. 250,000 CPU cores.. 2,300 Fermi GPUs
Size........................................ 284 cabinets............. 23 cabinets
Power draw.............................. 7-10 MW.................. 1.15 MW
Cost..................................... $50-$100 million ...... $11.5-$23 million
That's better (the marketing spin was getting to me). It shows cost differences isn't so great.
Anyway I'm all for GPUs (and any other solution) as Intel CPU performance over the past few years seems to be running out of steam so to speak, as its really not moving forward as fast as I had hoped. Even the available amounts of ram per motherboard are not getting much bigger. in fact many motherboards are going over to 2 memory slots not more slots :( ... Its all starting to feel like Intel CPUs are stuck with small incremental improvements. We do need a new way forward for all sizes of computers if Intel can't provide.
