Intel has done 6 core processors in the recent past, and there are currently 3 memory controllers on Nehalem cpus. The point of a 6 core processor is that's all that fits, plus there isn't enough memory bandwidth to support 8 cores with many workloads. The point of 3 core processors was selling at a lower price point, and being able to sell defective chips as good. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
