Latency, bandwidth, and HEXUS.PiFast
| ScienceMark 2 memory latency | |
|---|---|
| AMD Athlon II X4 620 (2.6GHz, 2MB L2) | Intel Core 2 Quad Q8200 (2.33GHz, 4MB L2) |

Both CPUs interface with dual-channel RAM, but the long-in-the-tooth FSB system adopted by Intel's LGA775 chips exhibits limitations with respect to pure memory bandwidth.
| HEXUS.PiFast - calculation to 10m places | |
|---|---|
| AMD Athlon II X4 620 (2.6GHz, 2MB L2) | Intel Core 2 Quad Q8200 (2.33GHz, 4MB L2) |

AMD's 266MHz clock-speed advantage isn't quite enough to beat out the Core 2 Quad Q8200 in the math-based HEXUS.PiFast test.
