The one between three and three.
holy shit this dude has no fuckin idea about the shit he's talking about!
Talmbout only recently were the XBox and PS similar to PC's when the original XBox was essentially a PC. It ran a 733MHz Pentium 3 processor with an Nvidia Geforce 3 derived GPU, 64MB of RAM, Nvidia SoundStorm audio (same thing integrated into nVidia nForce PC chipsets), and a hard drive. When it came out in '01, PC's were already on the Pentium 4 and faster Geforce 3 Titanium GPU's with the Geforce 4 dropping only a few months later so technically it was already behind the PC in terms of power.
Now, it's true that the PS2 was quite different from your normal PC. Everything in that box is completely custom.
XBox 360 is closer to a PowerMac than a PC considering they use the same type of processor: A PowerPC but one somewhere between a G4 and G5 PPC. The GPU is basically the same as a Radeon X1800XT but with a handful of features that wouldn't be seen until Terrascale (Radeon HD2000+).
He got one thing right: The XBox One as well as the PS4 uses another PC processor and it's built-in GPU: and AMD APU from the Kabini architechture.
