We compare three and four core AMD Phenom X CPUs, along with a large number of Athlon 64 X2 and Intel Core 2 two and four core models.

While you were reading all those great Tom's Hardware reviews, we'll bet you missed some really interesting hardware news stories. Here are the hottest ones from over the past two weeks.

After a 1 year+ delay, AMD has released its first quad-core CPU, the Phenom, along with a new platform, Spyder. We ran all 3 Phenom models through our extensive benchmark suite. Check it out.

Four cores, 45 nm structures and overclocking up to 4 GHz make Intel's Penryn Core 2 CPUs faster and more efficient. How bad does it look for AMD?

Exciting news about AMD's new unlocked X2 5000+ Black Edition. Complete with test results and comparisons

With our solar-powered PC and supporting components up and running, we present a variety of relevant data in near real-time.

In the second article in this series, we focus on the hardware required to run a desktop PC, including monitor, with solar cells 24/7. The PC consumes a world-record low of only 61 Watts!

The new L2 stepping of Intel's Core 2 Duo processors requires less power. But are AMD's EE-CPUs more energy efficient?

Tuned and tweaked to the max, the Intel 3.68 GHz processor faces off against AMD's 3.06 GHz all-purpose threat. Is the race over yet? Hasn't Intel won already? Let's see...

One month ahead of the Core 2 Duo launch, we take a look at the 2.66 GHz version and run benchmarks. Will Conroe really be Intel's Athlon 64 killer?

The AMD generation grows up. To introduce you to the new AM2 socket, we bring you a comprehensive analysis of the platform, processors and memory, along with benchmarks and purchase recommendations.

We gradually push memory modules to their limits, live and on two systems simultaneously. Review samples are pit against memory that we purchased.

We tested DDR2 modules from 16 vendors and gauged latency, overclocking capabilities and other features. Bottom line: tread carefully because there are big differences in performance.

THG looks at six dual Xeon mobos and their cooling solutions. For as little as $250, boards from Asus, Intel, MSI and Tyan have much to offer.

Gigabyte has taken another stab at making a viable CPU cooler and this time it's made of copper. Does Gigabyte's second cooling attempt deliver?
