Andy, re:"P7. Can you clarify this"

Sure, no problem...

In fact their is no "P7" at Intel. They have moved away from ordinal names due to the confusion caused by imitators.

Intel instead uses the term "Intel Architecture - 32 bit" and the term "Intel Architecture - 64 bit". It shortens this to merely IA-32 or IA-64.

IA-64 is for servers and workstations. Merced chip project will be the first processor, but their will be many variants for years to come.

IA-32 serves the whole market now, but I believe will move more exclusively to the desktop. Look for Katmai to introduce MMX2 followed later by Willamette.

The press is asleep! - Willamette is the great processor for us from Intel, not Merced. Willamette will be phenominal and cost effective, a true gigahertz processor. It will dominate the desktop. However it has been ignored by the press so far. This is just fine with me. Let the press chew on Merced and leave Willamette alone!

IA-64 will require new software infrastructure before it fully flowers. This fact will slow its ramp to perhaps ten years duration.

Basically, Intel has moved away from the "Px" designations. They've been creating so many new variations of their processors that it no longer suits their purposes.

Originally:

P5 - Pentium
P6 - Pentium Pro
P7 - Merced

Of course, then they came out with Pentium MMX, which is a variation on P5. And Pentium II, which they are marketing as a new product, is basically an MMXed version of P6, with the new slot architecture. Celeron will also be a variation on P6. So will Willamette.

Basically what's changed is that the processor offerings no longer move in a "linear" direction which favors the old numbering scheme. Rather the same base architecture can support a variety of "flavors".

These days they refer to everything in the old P5/P6 branch as "IA-32" and the old P7 branch as "IA-64". There are internal designations and project names for each individual variation.
