Are all E8400's created equal?

Nope, Penryn CPUs are the mobile 45nm Core 2 Duos, Wolfdale are the desktop 45nm dual cores, and Yorkfield are the desktop 45nm quad cores

So I was half right. Thanks for the correction

If you notice with the codenames, all dual-cores end in "dale" whilst all quads end in "field", so we have Wolfdale & Yorkfield with the current Penryn Core2 processors and "Bloomfield" with the new i7s. Going into the future we'll have Havendale/Lynnfield and Auburndale/Clarksfield.

This seemed to start with the original Conroe quad, which was called Kentsfield, as the original dual-core simply inherited the Conroe name.
