E.g. for single precision complex 1024x1024 2D FFT:
Cell (8 SPE):
38 GFLOPS
40W 0.95 GFLOP/watt
S870 (Tesla) GPU: 50 GFLOPS
170W 0.07 GFLOP/watt
x86 core:
3 GFLOPS
25W 0.12 GFLOP/watt
CSX700:
20 GFLOPS
7W 2.86 GFLOP/watt
• Next generation processor “Carnac” in design now
– Focusing on 1- and 2D FFT performance
– Design goal is 100 GFLOPS/watt sustained on 2D FFTs
