Intel · Xeon Gold · 2020 · LGA3647
The Intel Xeon Gold 6226R is a server processor with 16 cores, released in 2020 at an MSRP of $1,300. It is part of the Xeon Gold lineup, using the Xeon Scalable platform, and fits the LGA3647 socket. Internally, it is built on the "Cascade Lake" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 32 threads for improved parallelism. The Xeon Gold 6226R has a base clock of 2.9 GHz and can boost up to 3.9 GHz depending on workload and thermal headroom. Intel manufactures the "Cascade Lake" silicon on a 14nm process node. This processor supports DDR4 memory across 6 channels, up to 1TB 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 150W, the Xeon Gold 6226R runs hot and requires a capable cooling setup. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 22MB of L3 cache.
A Cascade Lake Refresh part (the 'R' suffix denotes the second-wave Cascade Lake refresh with revised clocks) supporting standard 2-socket configurations, unlike the single-socket-restricted 6208U it happens to share core specs with.
