The single page also shows that it may be the fourth quarter before Barton is launched, while it shows a Thoroughbred 2400+ at 1.93GHz slated for the third quarter, which as everyone knows starts at the end of June.
The Clawhammer appears to run at 2GHz or above, and is dubbed the 3400+.
But a further iteration of the Clawhammer chip, slated for the first half of next year has an M4000+ on the roadmap, while this will up to the M4400+ by the second half of 2003.
AMD will also introduce its Sledgehammer dual chips at M4000+ and they're now slated for the second half of 2003, if this roadmap is genuine.
