Xeon Gold 6246

Xeon Gold 6246R is a 64-bit 16-core x86 high performance server microprocessor introduced by Intel in early 2020. The Gold 6246R is based on the Cascade Lake microarchitecture and is manufactured on a 14 nm process. This chip supports 2-way multiprocessing, sports 2 AVX-512 FMA units as well as two Ultra Path Interconnect links. This microprocessor supports up 1 TiB of hexa-channel DDR4-2933 memory, operates at 3.4 GHz with a TDP of 205 W and features a turbo boost frequency of up to 4.1 GHz.

Cache[edit]

Main article: Cascade Lake § Cache

The Xeon Gold 6246R features a larger non-default 35.75 MiB of L3, a size that would normally be found on a 26-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.
