Core: Prescott Frequency: 3.6GHz Socket: LGA775 Process: 90nm Cores: One Instructions: MMX, SSE, SSE2, SSE3, EM64T Multiplier: 18x External bus: 200MHz Effective FSB speed: 800MHz Level 1 cache: 16KB Level 2 cache: 2,048KB The Pentium 4 600 series was Intel's first processor range
We tested processors from the top and bottom ends of the 600 series. The Pentium 4 640 runs at 3.2GHz and the 660 at 3.6GHz, and these are available for £160 and £275 respectively. This makes them only slightly more expensive than their equivalents in the Pentium 4 500 series. The 640 and 660's extra cache made little difference in PCMark04 and the Shopper application benchmarks. The 640 and 660's scores of 4,889 and 5,466 were only just ahead of the Pentium 4 540 and 560, and the 660 performed slightly worse than the 560 in the overall Shopper benchmark with a score of 128. The processors did manage an extra couple of frames in Far Cry, but their performance advantage will only become apparent in applications that take advantage of the 64-bit instruction set.
