Intel · Xeon E3 · 2013 · LGA1150
The Intel Xeon E3-1265L v3 is a server processor with 4 cores, released in 2013. It is part of the Xeon E3 lineup, using the Xeon E3 platform, and fits the LGA1150 socket. Internally, it is built on the "Haswell-WS" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 8 threads for improved parallelism. The Xeon E3-1265L v3 has a base clock of 2.5 GHz and can boost up to 3.7 GHz depending on workload and thermal headroom. Intel manufactures the "Haswell-WS" silicon on a 22nm process node. This processor supports DDR3 memory across 2 channels, up to 32GB total, with ECC support standard for data integrity in server workloads. It supports single-socket (1P) configurations, with 16 lanes of PCIe 3.0 available for storage, networking and accelerators. With a TDP of 45W, the Xeon E3-1265L v3 is an efficient chip suitable for modest cooling solutions. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 8MB of L3 cache.
Entry Xeon E3 v3 on the mainstream Haswell desktop platform, targeting small business workstations and servers.
