fyo, for the latest on McKinley, check out Paul Demone's recent report (2/18) covering the ISSCC. He also laments the demise of EV8 (as do we all).

realworldtech.com

From his conclusion:

In contrast to the EV8’s cold grave, the McKinley seems to have a bright future ahead of it. Unlike the execrable Merced, the second generation IA64 processor is a well designed chip with an incredibly capable on-chip cache hierarchy. That cache hierarchy, combined with many other measures to minimize instruction latency as well as increase the clock rate, should help McKinley overcome the burden of an ill-conceived and misguided instruction set architecture to yield respectable integer and floating point performance levels. By offering decent high end performance at relatively low costs (from its chip merchant business and potential economies of scale), Intel and its business partners will likely see strong customer acceptance when it officially releases McKinley later this year. Perhaps enough to turn the corner and start paying a return on the billions invested in IA64 over the past eight years.

I'm not sure about the 'low cost' conjecture, 300mm notwithstanding. This chip is huge.

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.


theinquirer.net

This was a IBM server road map published last year. Seems like they (this year) plan to extend the Power4 architecture all the way down to one way systems.

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).


I think I read somewhere that it would have less L3 cache. 3 or 3.5 MB. But it would be on chip and faster, and probably McKinley would have a bigger L2 as well.
