The Xbox CPU was basically a Celeron. They called it a Pentium but the cache said differently. The Gamecube essentially had a Power PC G3.

 

As someone not too familiar with CPUs, how does this make them fare aginst each other power wise, wth the Gamecube's CPU clocked at 485MHz and the Xbox one at 733MHz?

 

Those are indeed the clock rates but what most peopel don't understand is that different processors handle different amounts of work per clock cycle.   Think of it like what I am going to show you below.   The numbers are purely for example and do not perfectly reflect their actual capabilites.

Xbox @ 733 Mhz * 2 operations per clock cycle = 1.466 billion operations per second.

GC @ 485 Mhz * 4 operations per clokc cycle = 1.940 billion operations per second.

As you can see, even though the GC has a lower clock rate, it could still do more work in a given time interval.


The Xbox was 1 operation per cycle. The GC was 3. Test between the P3 and the PowerPC process showed that a 200mhz powerpc processor got an average of 3 times the performance over a 300mhz Pentium 3. So, it was 3 times faster at a lower clock rate.

Of course the processer in the Xbox isn't even a Pentium 3. Its a Pentium 3 based Celeron(low budget Pentium 3 with less features) so it doesn't get as high performance as the real thing.
