I might have to build an intel system to justify not selling my vapo now...
Not sure I want to mention this but... AMD chips were actually designed and optimized for lower voltages at the mainstream frequencies [for such uarch/fabrication] right since the early beginning. Hence it won't be odd to find they love voltage only in a low range and do not scale past it unless process tweaked. As Execs at AMD have explained, critical path delays were increased for this but need decreasing for higher clocks.

Also, AMD now has the 2.5GHz Barcelona 2360 SE retailing at 105W TDP: http://www.amd.com/us-en/Corporate/V...l?redir=CPPR01

So they now [finally] have 1.7G, 1.8G, 1.9G, 2.0G, 2.1G, 2.2G, 2.3G, 2.4G and 2.5G retailing in that segment - all of which were set to release by December '07 had there not been this TLB bug and a reason why they lost much profit over increased costs.


Any details on nV 780a?
