Xeon Platinum 8260Y is a 64-bit 24-core x86 high-performance server microprocessor introduced by Intel in early 2019. The Platinum 8260Y is based on the Cascade Lake microarchitecture and is manufactured on a 14 nm process. This chip supports 8-way multiprocessing, sports 2 AVX-512 FMA units as well as three Ultra Path Interconnect links. This microprocessor supports up 1 TiB of hexa-channel DDR4-2933 memory, operates at 2.4 GHz with a TDP of 165 W and features a turbo boost frequency of up to 3.9 GHz.

As indicated by the "Y" suffix, this model features Speed Select Technology (SST). It can be configured at 3 different core counts and frequencies - 24 cores, 20 cores, and 16 cores.


Cache

Main article: Cascade Lake § Cache

The Xeon Platinum 8260Y features a larger non-default 35.75 MiB of L3, a size that would normally be found on a 26-core part.

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.
