A smartly engineered processor, but for today’s applications it’s lacking in bang per buck.

We've put AMD and Intel’s new processors to the test, and there's one clear winner.

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

We test AMD’s first quad-core processor for both speed and power efficiency

Impressive technology, but increasing cores doesn’t necessarily increase performance.

Performance per watt has taken a backward step, but it’s very fast with the right apps.
