Well you have peak flops, then peak single or double precision flops. You can also add what the GPU can achieve. I guess the Wired figure is Cell + RSX single-precision peak flops + marketing BS. The Terrasoft figure looks conservative: one SPU can do 4 macs per cycles, which translates into 8 flops. At 3.2 GHz, each SPU can achieve 25 Gflops. So 7 SPUs can reach >170 Gflops, plus what the PPU can do, which would probably give around 200 Gflops.
