The Intel Xeon E5503 is a server processor with 2 cores, released in 2010. It is part of the Xeon 5500 lineup, using the Xeon 5500 platform, and fits the LGA1366 socket. Internally, it is built on the "Gainestown" architecture. It operates at a fixed 2 GHz. Intel manufactures the "Gainestown" silicon on a 45nm process node. This processor supports DDR3 memory across 3 channels, up to 144GB 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 E5503 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.
Xeon 5500 series — the first Nehalem-based Xeon, introducing an integrated memory controller and QuickPath Interconnect.
