Dempsey
From TPU Reference
ronococoa monbasbocca Dempsey is the first Socket 771 Xeon released. Unlike its successors it is not based on the Core 2 architecture. Instead it is basically a Pentium D with Hyper-Threading enabled. This allows a single processor to process 4 threads, a dual processor setup even acts like 8 processors. Even though it is quite strong on paper it has the same issues as it's Pentium D (EE) brethren. It doesn't perform that great and it runs quite hot.
