Intel · Xeon Gold · 2017 · LGA3647
The Intel Xeon Gold 5122 is a server processor with 4 cores, released in 2017 at an MSRP of $1,221. 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 8 threads for improved parallelism. The Xeon Gold 5122 has a base clock of 3.6 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 105W, the Xeon Gold 5122 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 16.5MB of L3 cache.
1st-generation Xeon Scalable (Skylake-SP) Gold part with 4 cores at 3.6GHz base / 3.7GHz turbo and 16.5MB L3 in a 105W envelope, launched 2017. Unusually for a Gold 5100-series part, the 5122 gets two AVX-512 FMA units per core and DDR4-2666 support, trading core count for clock speed.
