We are told that the NDA goes up on the QX6800 Monday, the samples floating everywhere now are 2.93GHz on a 1066FSB, basically matching the current X6800 clock for clock.
Q2 production will be in the low thousands ... the parts are going to be closer to 150W ...
The real QX6800s will come out in Q3 with a new stepping of the core Core number core numeral 2. This new stepping will drop power we are told 'substantially', and pave the way for volume QX6800 production. It also bodes well for a dual core speed bump, but that may not be in the marketing cards.
