Looks like there's not much on the Penitum M front through 2005, although I'm hoping Yonah will make it out, even if in limited quantities.

Why is this a bright spot? Enter Alviso, the new PM chipset debuting in a January. This offers dual channel DDR2-533 support and a 533MHz FSB, along with other goodies like PCI-Express. How well does it do? Try 1685/1304 at 2133MHz.

For a comparison, and Athlon 64 FX-53 at 2.4GHz scores 1623/1595 and a P4EE at 3.4GHz hits 1667/1578.
