I don't think any of our many subsidiaries are even considering IA-64 as viable technology. While its slightly too early to tell, I think McKinley will have a decent shot of landing heavy-duty scientific calculation contracts. Merced was "ok", reaching around 700 in SPECfp (compared to almost 800 for 2.2GHz P4, with the latest UltraSPARC slightly higher and Alpha21264C & Power4 significantly ahead), but likely significantly hampered by the slow FSB (100MHz, IIRC). All scores here are single CPU results. Consider what McKinley might accomplish with significantly higher operating frequency, higher memory bandwidth, significantly higher FSB (4x, if my 100MHz is correct) and likely more L3 cache (Merced is equipped with 4MB L3 (off chip), which isn't a heck of a lot for this class of CPU). And that's discounting other architectural improvements and the almost certainly significant compiler gains. I assume McKinley system costs will be on roughly par with the top Sun systems and significantly below Power4 (this might depend on how heavily IBM chooses to push Power4 in the lower price-ranges (right now, the cheapest Power4 system will run a cool quarter million USD). IBM seems to have left Power3 to handle the mid-range and unless this changes by the time McKinley comes out, Intel would seem to have a pretty good shot at decent sales of McKinley. Remember, most of these FP scientific computing applications can be recompiled relatively easily and most companies / departments (in my experience, anyway) don't run a lot of different applications, so any porting work would be manageable. -fyo
