Intel · Xeon E3 · 2015 · LGA1151
The Intel Xeon E3-1280 v5 is a server processor with 4 cores, released in 2015. It is part of the Xeon E3 lineup, using the Xeon E3 platform, and fits the LGA1151 socket. Internally, it is built on the "Skylake-DT" 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 E3-1280 v5 has a base clock of 3.7 GHz and can boost up to 4 GHz depending on workload and thermal headroom. Intel manufactures the "Skylake-DT" silicon on a 14nm process node. This processor supports DDR4 memory across 2 channels, up to 64GB 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 80W, the Xeon E3-1280 v5 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 8MB of L3 cache.
