You really can't directly compare a PowerPC XBox/PS3 processor to a PC x86 processor, because they're two entirely different architectures. A basic comparison of # of cores and clock rate is meaningless. The only way to compare hardware performance is to get deep into the architectures. It's not something where you can do a quick side-by-side comparison to determine.
That is a very good point, indeed! I do not have in-depth knowledge about the xbox architecture, but I DO know the ps3 very well, having programmed it at low level for high preformance scientific simulations for the past 4 years.
The ps3 has a 3.2GHz Cell/BE processor, which consist of 8+1 cores. The "main" core is a PowerPC core, but the real kick comes from the 8 SPUs, which are synergetic vector processors, each capable of executing 8 floating point operations per cycle, so a total of 65 floating operations can happen parallel, giving a peak performance equivalent to 65 cores.
I do not think there are too many 65 core gaming PCs around even today -- so not bad from a 5-year-old junk
