Overclocking: Core i7 Vs. Phenom II

Tom's Hardware: "This match-up needs no introduction-but I'm going to throw one down anyway.

It's no secret that Intel has dominated our performance tests over the past year. First, its Core 2 Duos at 45 nm gave enthusiasts a great platform for aggressive, yet relatively safe overclocking. The company's Core 2 Quads cost quite a bit more, but they managed to deliver smoking speeds in the applications optimized for multi-threaded execution.

The recent Core i7 launch further cemented Intel's position as the performance champion. Its Core i7 965 Extreme, clocked at 3.2 GHz, demonstrated gains straight across the board versus its outgoing flagship, the Core 2 Extreme QX9770. And the Core i7 920, Intel's sub-$300 entry-level model running at 2.66 GHz, seems to have little trouble reaching up to 4 GHz on air cooling.

There was once a time when Intel didn't handle its technology shifts as smoothly. As recently as the Pentium 4 Prescott core (OK, that was a while back), Intel struggled to maintain an advantage against AMD's Athlon 64. But now, with the marketing of its "tick-tock" approach to rolling out lithography advancements and micro-architecture tweaks, things have certainly turned around. How is AMD expected to compete?"
