"AS to the Intel rep, ask him for his druggist's name. Then ask him how many DARPA HPC awards for computer technology Intel received at SuperComputing '06 last November in Tampa despite having 30 core 2 Duo and 1 Quad core entries. The answer is 0. Then ask him how many AMD got and for which chip. The answer is 4 for the 939/940. IBM got the other 8. Ask him where Intel finished in DARPA's Petascale contract competition. Answer is last IBM split honors with AMD/Cray and IBM has agreed to make the P7 interchangable with the AM3+. Sun's Rock was 3rd. Intel's wonderful technology has shut them out of the HPC market through the end of 2010."
Intel systems can't scale due to the FSB bottleneck.
