Intel · Xeon (Harpertown) · 2008 · Socket 771
The Intel Xeon L5408 is a server processor with 4 cores, released in 2008. It is part of the Xeon (Harpertown) lineup, using the Xeon (Harpertown) platform, and fits the Socket 771 socket. Internally, it is built on the "Harpertown" architecture. It operates at a fixed 2.133 GHz. Intel manufactures the "Harpertown" silicon on a 45nm 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 40W, the Xeon L5408 is an efficient chip suitable for modest cooling solutions. The cache hierarchy consists of no dedicated of L1 and no dedicated of L2 cache. There is no L3 cache on this processor.
45nm quad-core Xeon DP on Penryn architecture, a major efficiency improvement over Clovertown.
