otherwise their
next year pIII-1.13GHz processor would be faster than p4-1.5GHz


Albert,

Several members of the thread (myself included) speculated back some time that this was in fact the reason Intel delayed the 1.13Ghz.

albert, the 10-20% slower IPC is for legacy code. I expect they can make up that amount using SSE2 for certain aps, like the benchmarks they preload onto the hard disks of the systems sent to reviewers.

In fact, they will probably preload so many Intel benchmarks that there is only 1% free space left!

Albert, I think the leaked Billybob spec numbers still look like the best estimate. 502 specint2k, 525 specfp2k, compared to best numbers of 438/327 for 1ghz piii/OR840 or 461/320 for the late, lamented 1.13ghz / VC820. These numbers are not directly comparable with AMD because of the compiler factor, but I think the 14 % increase vs. the 1ghz cumine on Specint is a reasonable estimate for non-fp stuff. The big jump in FP is heavily dependent on both the compiler and SSE2 optimization, but that's what will look best; x87 FP stuff will likely look worse than integer results.

Chees, Dan.
