Cell Processor performance - upto 100x Intel Xeon in certain operations

These are a lot of slides, but this is a normalized comparision between an
Intel Xeon processor (pumped up Pentium 4) to Cell in what's known as a
Fourier Fast Transform. At a 256 point FFT each SPE is slightly more
powerful than an entire Xeon making Cell as a whole greater than 7x faster
than the Intel chip. Under the circumstances of the 16 million point FFT,
there's no competition. 100x faster. Xeon ran out of bandwidth and
computational resources. Cell kept on going.

Idiot.

Idiot.

While your _Newsflash_-statement stands undisputed, there is no need to
go ad hominem. At least not as long TOP500 is published on a
Linpack-score. :-)

Hmm, I wonder if Cell could keep up against an Opteron running TPC-C?
