AMD's Bobcat and Bulldozer

[terrace215]

The guy left AMD when the core was half-canceled .
The 50% figure is just AMD being careful ,that's all.Nobody will criticize them if the over deliver,but not vice versa.

Did you stop to think about how Alsup's comments on comp.arch echo AMD's slide bullet point....

Alsup: 5% loss due to u-arch trimming to meet higher frequencies
AMD: "without significant loss in single-thread performance"


So... yeah, it's about the changes in the integer side of the "module" from K10.5 to BD. They hope for higher frequencies to get back to gains, but the net is 15-20% for single/low-threaded work. Not nearly enough to catch SB.

SB-EX for consumers?That's,IIRC, not even on the 2011 server roadmap.

It's down for Q4 2011.
