Intel · Xeon Gold · 2017 · LGA3647
The Intel Xeon Gold 6145 is a server processor with 20 cores, released in 2017. It is part of the Xeon Gold lineup, using the Xeon Scalable platform, and fits the LGA3647 socket. Internally, it is built on the "Skylake-SP" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 40 threads for improved parallelism. The Xeon Gold 6145 has a base clock of 2 GHz and can boost up to 3.7 GHz depending on workload and thermal headroom. Intel manufactures the "Skylake-SP" silicon on a 14nm process node. This processor supports DDR4 memory across 6 channels, up to 768GB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 48 lanes of PCIe 3.0 available for storage, networking and accelerators. With a TDP of 145W, the Xeon Gold 6145 sits in a typical power envelope for a modern desktop CPU. The cache hierarchy consists of 64KB/core of L1, 1MB/core of L2, and 27.5MB of L3 cache.
1st-generation Xeon Scalable (Skylake-SP) Gold part with 20 cores at 2.0GHz base / 3.7GHz turbo and 27.5MB L3 in a 145W envelope, launched 2017. Gold 6100-series parts get two AVX-512 FMA units per core, DDR4-2666 support and three UPI links for four-socket systems.
