From what I have seen, AMD generally has the performance edge until you step into the dual market. Then you have to be very careful as several AMD tests posted here by others (not by me as I have no AMD boxes here at all) suggest that the AMD duals have a memory bottleneck that limits performance. However, it is also likely that there are both good and bad chipsets for supporting duals. Intel has a "workstation" class dual xeon chipset and a "server" class chipset. The server class chipset has better memory performance. It it were _my_ money, I would benchmark the program(s) I want to run on the box before making the decision. As I said, there are certainly bad AMD chipsets for duals. There are _also_ bad Intel chipsets for duals. Common sense says "benchmark" or get data directly from someone that has the _specific_ chipset you are looking at. All duals are not created equal. Hyper-threading is yet another issue. Remember that you have to run two threads to take full advantage of one physical CPU. On AMD this is not true. Hyper-threading speeds things up significantly. But that second thread also has a cost, particularly if you don't have a second thread to run. :)
