Intel · Xeon E5 · 2016 · LGA2011-3
The Intel Xeon E5-4667 v4 is a server processor with 18 cores, released in 2016. It is part of the Xeon E5 lineup, using the Xeon E5 platform, and fits the LGA2011-3 socket. Internally, it is built on the "Broadwell-EP" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 36 threads for improved parallelism. The Xeon E5-4667 v4 has a base clock of 2.2 GHz and can boost up to 3 GHz depending on workload and thermal headroom. Intel manufactures the "Broadwell-EP" silicon on a 14nm process node. This processor supports DDR4 memory across 4 channels, up to 1.5TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 40 lanes of PCIe 3.0 available for storage, networking and accelerators. With a TDP of 135W, the Xeon E5-4667 v4 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 45MB of L3 cache.
Xeon E5 v4 — final generation on the LGA2011-3 platform before the Skylake-SP architectural overhaul.
