Revision as of 18:40, 18 October 2018
The CPU in the Xbox was a custom Pentium III running at 733MHz. The 'custom' part of this was that that the Pentium III in the Xbox was that it had only 128KB L2 cache instead of the usual 256KB. This allowed Microsoft to buy them at a bit of a discount and Intel to shift a few more CPUs[citation needed].
