Cinebench Release 10, Superpi and WprimeNeck to neck race here, with the smallest advantage for the E8600. Cache seems to have zilch effect in this benchmark, neither does a higher FSB.
SuperPi works in a similar way as 3dmark2001. Tight latencies and cache...all seem to help to nibble of them precious thousands of a second. It's nice to see this benchmark scale with increased CPU speeds. The gap closes between the 2 cpu's when we increase total CPU speed, so the extra cache loses some of its effectiveness.
Wprime32 is a brute CPU powerhog test. Like with Cinebench there's not much that differentiates these 2 CPU's. Total CPU speed rules cache for sure...
The latter findings are also nicely reflected in Wprime 1024 :
The E8600 starts strong at 2.66Ghz with over 8 secs advantage over it's little brother. However once we crank up the CPU speed it's so extremely close that we cannot hand over the victory to the E8600.
