GR1EVER,
The 128-bit label can be a bit deceiving unless you know what you are comparing. The PS2 CPU is actually inferior to modern video cards which have GPU's that can operate at 256-bit. In a PC, the job is split up between the CPU and GPU, with the GPU doing most of the work. The Xbox uses a similar setup and actually has 128-bit access to memory.
In terms of graphics, GPU's are far more advanced than CPU's. That is because they're more specialized. A CPU, on the other hand, is running on a 32-bit OS and normally only processes code at 16 or 32-bit. It is an apples-to-oranges comparison to pit a GPU against a CPU. Besides, that same PS2 processor is only running at 300MHz, far slower than what you would expect to buy on the PC today.
