Intel · Xeon 5600 · 2011 · LGA1366
The Intel Xeon E5603 is a server processor with 4 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. It operates at a fixed 1.6 GHz. 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 80W, the Xeon E5603 sits in a typical power envelope for a modern desktop CPU. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 4MB of L3 cache.
