Wanna: I compared the 1.73GHz Athlon XP with the 1.7GHz Willamette. To estimate Northwood, I multiply the result by the percentage that the 2.0A beats the 2.0 in each app, and I also include the percentage that the 2.4B beats the 2.4A in each app. The parenthesis represent negative IPC gains. I think you may be overanalyzing (cough). Many of the benchmarks you cite are extremely memory bandwidth-sensitive. Others are extremely cache-sensitive. In both these cases, it is not unreasonable to assume that a Clawhammer will do very well (compared to an Athlon, given the higher bandwidth to memory, much lower latency to memory and larger L2 cache). Sledgehammer, with its 128bit memory controller will do extremely well. (I'll hold off on any claims of 1MB L2 cache until I see them - it occurs to me that we've heard that "chip-with-larger-L2-cache" a little too often). -fyo
