The "24 GFLOPS" in RP come from the GPU (Videocore IV, 32-bit precision) [1].
The PS3 does more than 230 GFLOPS, just with the Cell processor (1 dual threaded CPU and 7 vector units -CPUs with wide SIMD, working in 256KB local scratchpad RAM-) [2]. In addition to that, the PS3 GPU does 400 GFLOPS [3]. So the PS3 is "600 GFLOPS" (32-bit precision).

- rektide 10y agoOh my goodness how right you are. I'm very sorry! I should have checked this far better. Again, super sorry. I believe I was unintentionally citing that a single Cell SPE is 25.6 GFLOPS: https://en.wikipedia.org/wiki/Cell_(microprocessor)#Synergistic_Processing_Elements_.28SPE.29 https://en.wikipedia.org/wiki/Cell_(microprocessor)#Synergis...
