Intel · Xeon 5600 · 2011 · LGA1366
The Intel Xeon L5645 is a server processor with 6 cores, released in 2011. It is part of the Xeon 5600 lineup, using the Xeon 5600 platform, and fits the LGA1366 socket. Internally, it is built on the "Westmere-EP" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 12 threads for improved parallelism. The Xeon L5645 has a base clock of 2.4 GHz and can boost up to 2.933 GHz depending on workload and thermal headroom. Intel manufactures the "Westmere-EP" silicon on a 32nm process node. This processor supports DDR3 memory across 3 channels, up to 192GB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 36 lanes of PCIe 2.0 available for storage, networking and accelerators. With a TDP of 60W, the Xeon L5645 is an efficient chip suitable for modest cooling solutions. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 12MB of L3 cache.
