A lightweight and cost efficient power supply.

Highly efficient PSU keeps things cool and quiet.

Quiet PSU with good efficiency.

A Power supply built with a little too much power and too little warranty.

A world first on the desktop, Phenom is good but a long way from outstanding.

This first of a new generation is only a little faster than the old, but its potential is clearly huge

When Intel announced the production of 90nm products over a year ago, the most obvious change was the move to double the existing 512KB L2 cache to a full 1MB of on die memory. This simple transition added more performance than some of the minor clockspeed increases to date, and made the Prescott a household name.

Synonymous with cost effective CPUs, Intel's Celeron has carved a market for itself by producing products which are reliable and boast something many others cannot – interoperability. This has been achievable by producing products that work with the same socket 478 pin configuration found across the entire range of processors.

In the performance stakes the 3200+ came up trumps, finishing middle to top of the pack and clearly cementing itself as a solid performing processor for home, office or pure entertainment.

The latest iteration of the Pentium 4, code named Prescott, is an interesting development for a few reasons. First off, it represents Intel's entry to the world of 90nm (90 nanometre, or 0.09 micron) fabrication for processors. For the uninitiated, all this means is the size of individual components on the processor core have been shrunk to even smaller levels. It's a natural part of processor evolution to shrink the size of components, as it allows more transistors to be packed into a smaller space, reduces heat and resistance, and this all leads to faster CPUs.
