Jim, Re: "get to McKinley and somehow castrate Foster" How do you know that Intel has to castrate their IA-32 line to make their IA-64 line look better? How do you know that McKinley doesn't outperform of its own accord? wanna_bmw

Jim, It's beyond me why Intel would what to put 512k on a mainstreaam desktop chip when it's already outscaling the competition by 600 Mhz. Basically, 2 reasons: a) they can, meaning Northwood with 512K L2 is a reasonable size, and actually since there are redundancies in L2 silicon, even the large silicon area doesn't reduce the yields as much as logic could b) I think there is an important feature of the L2 that has been only briefly touched on and that is multiplier. With multiplier of 20, each L2 miss will stall the CPU for 20 x the RAM latency CPU cycles, which in case of 10 bus cycle latency would be 200 CPU cycles. As the multiplier increases, so does the damaging effect of an L2 miss on the overall performance of the CPU. Joe
