Which CPU does the XBox have?

At first everything seemed as clear as day. According to Intel and Microsoft, it should be a Pentium III 733Mhz. But shortly after the console was released, some hobbyists had doubts. The processor of the XBox has only 128KB cache, a typical feature of the Celeron.

However, the front side bus of 133Mhz used speaks of the 'big brother' PIII. In response to several inquiries, Microsoft and Intel have now announced that the CPU is an in-house development for the XBox. Although it is based on the Pentium III, it has undergone a number of modifications. According to Intel spokesman Christian Anderka, it is so to speak 'an embedded processor based on the Pentium III'.
