quote: On a multicore chip, I can't see HT doing very much for performance until CSI and Nehalem is released in 2008/9 (remember that the bottleneck nere is the FSB).
quote: Backup what you are saying.
quote: State how much bandwidth cache coherency traffic takes up on the FSB.
quote: Ummmm....This is K8L we're talking about, not some fanciful chip that's always five years away
quote: where in the article is empirical evidence that the FSB has become saturated or is a bottleneck?
Answer: There isn't any, it's all conjecture
quote: Yeah, prove a negative, that will work
quote: Please point me to this scientific evidence you speak about.
quote: Even though I'm not the one making the statements (you are)
quote: Using Intel analysis tools, running business applications, I see FSB utilization in the 15% percent area on a dual core HP system. Running the same on a quad bumps the utilization to 18%-20%. Business applications run out of cpu long before then run out of FSB bandwidth.
