Elmer, <they don't know the performance boost Intel will enjoy with larger on-die L2 cache> Intel will "enjoy" at most 3% "boost" as usual. It is well known to everyone "skilled in the field" The reason is in the Intergraph "Clipper" patents on cache coherency support and bus snooping protocols. Due to this and 4-way-associative cache designs (I wonder where Intel stole those), the cache system is already so effective that almost no improvements could buy you any performance. This is called "Amdahl law" if you are not familiar with basic engineering. You seem to never learn from your old and failed expectations: remember FX-LX-BX performance "breakthroughs"? Remember P-II-to-Xeon at the same clock rate? <they are not comparing performance to Coppermine and it's Camino chipset.> Ha-ha-ha. See above.

EP: How could they when they don't know the performance boost Intel will enjoy with larger on-die L2 cache. They could know, if they used their brains. Or at the very least get a very good estimate. Intel has released plenty of benchmarks (everything from Winstone to SPEC) on the Dixon. Comparing those to PII scores should give a very good indication of the performance increase that we can expect (in non-SSE stuff) from the CuMine. With regards to the first reply to your msg: The increase is significantly above 3%. It's on the order of 10%. --fyodor
