Doug: Using the x87 benchmarks, K8 was 100% faster than P4. Intewl only showed selected benchmarks. Heck AMD did show a benchmark that got over 400% improvement (encryption). Remember that P4 didn't have 64 bit at that time. And using that same clock for clock comparisons you seem so fond of lately, a 1.8GHz Opteron took a 1.8GHz Northwood to the cleaners. The advantage was even bigger when you compare 2 socket, and in 4 socket, it just destroyed P4 Xeons. Your memory is faulty. Go on back and look it up. Use clock for clock IPC. Here is one test from Anandtech of a 2GHz Opteron versus a 3GHz Northwood and a dual 3.06GHz Xeon DP: anandtech.com Gaming is one area where our tests show Opteron at 2.0GHZ an amazing performer. When you find game benchmarks 10% to 20% higher, you are genuinely impressed. However, in some of the very latest DX9 benchmarks, Athlon64/Opteron was 40% to 50% faster. This will get the attention of the gaming community, which seems to have a genuine affection for anything AMD already. It is the kind of trend-setting performance that Athlon64 needed to get the attention of an influential market segment. 1.4*(3GHz/2GHz) = 2.1 or 110% faster! <September 2003> Here is a DBMS test where a 2S Opteron 240 (1.4GHz) outruns a dual Xeon 2.8GHz: anandtech.com On an IPC basis, Opteron 240 gets about 108% more IPC than 2.8GHz Xeon DP. Here is a web server test from the same article: anandtech.com Here Opteron 244 gets about 143% faster in wait per clock than 2.8 Xeon DP and 138% more pages served per clock than the Xeon DP. And these were with MBs at launch, not the better chipsets like Nforce3 that appeared later and/or the faster memory. And note none of these tests used 64 bit mode which the Northwood couldn't do. These are selected benchmarks of course, but that is no different than what has been released thus far wrt Conroe/Woodcrest/Merom. And I have seen non synthetic benchmarks where 2.4GHz A64 X2 939 beats 2.4GHz Conroe. Pete
