Well enough, really. The PS3 will have - from what I've read - up to 8 Cell processors, and while you need to have more to really get the reported exponential gains in power, that's still going to put out an impressive amount of oomph. While this doesn't quite scale to the number reported for the PS3, it's said that 64 Cell cores (individual CPUs, working together) will perform on a level with 2200 G5s, or 2000 Athlon 64s, so you can imagine the results.

Sony and IBM announced that they'd created a workstation based on the Cell processor tech yesterday, actually...earlier news said they wanted to be selling them in time for Christmas.
