The Sony PS3 uses the Cell processor provided by IBM, which is essentially a PowerPC CPU + 8 SPE cores. It's worth noting that Apple's PowerMac G5 also used a Power processor. So, let's do a comparison test. Even though they come from different eras — one is a game console still in production while the other has already been discontinued — comparing them does feel a bit like pitting Guan Yu against Qin Qiong (a battle across time). However, since there are so few computers that use IBM's CPUs, this is why we can only compare Sony's PS3 with the PowerMac G5.
