A > Quad uses 95 watts, a dual uses 65 watts. where do you think the extra 35W is going to? is it duplicate circuitry, more circuitry( maybe larger cache )? Where the same technologies used for the two comparison power usage numbers or does the quad use a denser technology? it seems pretty obvious that inter CPU buses will be faster in a quad core compared to a dual CPU configuration but isn't that only going to help much in a heavily threaded application? And having dual dual-cores, how much, if any, of the multi-threading is going to get handed outside of one dual-core to the other dual-core? definately an interesting subject and I wonder if it still holds true that a dual cpu setup is cheaper than a multi-core setup. When dual cores first came out, they were quite expensive and multi CPU systems were a bit less expensive to put together. Now, multi-cores are all over the place so I don't know if the financial differences stil hold true. Doug -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
