A few links on the Merom chip.
Some interesting links regarding Intel's Merom - the chip scheduled to replace Yohah. Multiple cores and 4 MB of L2 cache. As opposed to PPC, it's nice to "see the future" a bit with Intel. These are slated, apparently for later '06 introduction.
http://www.theinquirer.net/?article=23055 - details the 64 bit dual cores for desktop and notebooks and the 4-core Xeon member of the family.
"There are three chips. Merom, the mobile part, Conroe, the desktop, and Woodcrest, the Xeon. They will be followed by Whitefield, essentially a four core follow on to Woodcrest. All of them, except Whitefield, will be dual core from the start.
All of these parts will be completely new from the ground up. The talk of them being Pentium M based is complete bull because these are next generation "brains of the computer". They have all of the features of the current chips, all the *Ts (Socket Ts), and a few more, and of course are 64 bit. The most surprising bit is that they will not have on die memory controllers on Merom and Conroe. Woodcrest will be FBD (fully buffered DIMM) enabled, so look for the potential to have stupidly large amounts of RAM on it."

" If you are wondering about the rather anaemic 65 nanometre Pentium 4 based dual core offerings, wonder no more. This is all because all the engineers were pulled off the projects to make Merom a smashing success. The PRs were gagged. The early word is all thumbs up and ahead of schedule. The 65 nanometre process, it appears, is well beyond healthy, and has some surprises lurking.
The chips will be "out" starting in late 2006 with Merom, followed by Conroe, then Woodcrest. We expect them to be publicly shown at the next Spring IDF, and perhaps Chipzilla will lift the veil and show off a couple of early early samples at Fall IDF, if there is one. Nut Intel may not have functional silicon by then."
