Ref < All I know is that it doesn't take that much more silicon to add another thread to the pipeline. Of course, the real trouble is debugging the processor design. >

My take is that Willamette and Northwood chips already have the transistors needed for the Jackson technology. Intel is awaiting verification before enabling the multi threading capability, and it will gradually ramp the percentage of chips shipped with Jackson technology enabled.

I think that Jackson technology will be a winner. Large amount of Application Software which fully utilizes this will be slow to appear, because of the difficulty in verification. However a large body of software already exists already written with multi threading in mind. All operating systems have been written for multi processor systems, and these will need a minor tweak for Jackson Technology. All server software will also benefit immediately. All operating system have a minimum of two threads:
(a) One for at least one application,
and (b) One for operating system housekeeping.
For example the application can be processing data, while the operating system is updating the display,caused by changes in the user output. Thus the applications will indeed run faster, even though there been no change in source code. The improvement may not be the 40% number bandied around, but there will be a tangible improvement in speed. I hope that Windows XP has Jackson Technology already in mind.

Another question about L3. The Intel slides show an L3. I presume that some Northwood versions will incorporate a cache controller for the OFF CHIP L3. I hope that SSE will now support L3 cache control instructions.
