Y. - As long as were posting BBS content, here's a neat little blurb I caught from JC's regarding Coppermine's cache:

jc-news.com

The latency of the L2 cache is not known to me, though it will likely be in the teens. The Celeron's L2 latency is something like 11 cycles, the K6-3 is 13ish cycles, the Katmai/PIII is 27 cycles, the K7 is 24 cycles (the newer two speed grades may have a slightly higher latency, for obvious reasons), the Coppermine/PIII is 7 cycles (this is an amazing, commendable, nearly impossible achievement, and it explains 90% of the way why the PIII is able to attain parity with the Athlon). In my opinion (I am not an expert, but I pretend real well), Jedi's L2 latency will probably be along the lines of the K6-3's (that's just my WAG, though).
