PROCESSOR

The 400 MHz system bus is really a quad pumped (QDR)100 MHz FSB. Meaning this, for every clock cycle it sends 4 pieces of data to the CPU delivering an incredible 3.2GB/s worth of bandwidth. That's about three times more bandwidth then what a Pentium 3 would get with a (1.06GB/s) 133 MHz FSB.

Along side the introduction of the Pentium4, Intel stated the heart of the Pentium4 is powered by its NetBurst Micro architecture. What that incorporates is pictured below.

When Intel released their Pentium 4 about 1-1/2 years ago, it was met with mixed emotions. While boasting an incredible of 1.5 GHz (which was a lot back then) it's performance was close to that of their Pentium 3 1.0 GHz CPU, even though it had a 500 MHz advantage the P4 1.5GHz is hardly cheap, but it is quite inexpensive compared to the top of the line Pentium4 models.
