[QUOTE="Prometheus, post: 73656"] yeah you just about got it there. Your "tubes" are processor pipeline stages. The G4 has far fewer pipelines than the P4. So although in theory the P4 can crunch more data, it has to go through more pipelines. Also most processes reliy on the data that has already been processed, so while the G4 has completed its calculations, and the next step can be performed, the P4 has to wait till its gone through all of its stages. Its this reason why the two processors cannot be directly compared, as in some situations, the G4 is much faster, and others the P4 is faster. It also means that you cannot compare processors on Ghz alone. [/QUOTE]
