Xeon Gold 6126F is a 64-bit dodeca-core x86 multi-socket high performance server microprocessor introduced by Intel in mid-2017. This chip supports up to 4-way multiprocessing. The Gold 6126F, which is based on the server configuration of the Skylake microarchitecture and is manufactured on a 14 nm+ process, sports 2 AVX-512 FMA units as well as three Ultra Path Interconnect links. This microprocessor, which operates at 2.6 GHz with a TDP of 135 W and a turbo boost frequency of up to 3.7 GHz, supports up 768 GiB of hexa-channel DDR4-2666 ECC memory.

This specific model incorporates the Omni-Path Host Fabric Interface (HFI) die in the same package as the processor.

The 135 W of TDP for this microprocessor consists of 127 W for the CPU and 8 W for the fabric.

Cache[edit]

Main article: Skylake § Cache

The Xeon Gold 6126F features a considerably larger non-default 19.25 MiB of L3, a size that would normally be found on a 14-core part.

[Edit/Modify Cache Info]

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
