Intel · Xeon (Dempsey) · 2006 · Socket 771
The Intel Xeon 5020 is a server processor with 2 cores, released in 2006. It is part of the Xeon (Dempsey) lineup, using the Xeon (Dempsey) platform, and fits the Socket 771 socket. Internally, it is built on the "Dempsey" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 4 threads for improved parallelism. It operates at a fixed 2.5 GHz. Intel manufactures the "Dempsey" silicon on a 65nm process node. This processor supports FB-DIMM DDR2 memory across 2 channels, up to 32GB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 24 lanes of PCIe 1.0 available for storage, networking and accelerators. With a TDP of 95W, the Xeon 5020 sits in a typical power envelope for a modern desktop CPU. The cache hierarchy consists of no dedicated of L1 and no dedicated of L2 cache. There is no L3 cache on this processor.
Dual-core NetBurst-based Xeon on the new Socket 771 'Bensley' platform, a transitional chip ahead of the Core-based Woodcrest.
