'''Xeon Platinum 8260Y''' is a {{arch|64}} [[24-core]] [[x86]] high-performance server microprocessor introduced by [[Intel]] in early [[2019]]. The Platinum 8260Y is based on the {{intel|Cascade Lake|l=arch}} microarchitecture and is manufactured on a [[14 nm process]]. This chip supports 8-way multiprocessing, sports 2 {{x86|AVX-512}} [[FMA]] units as well as three {{intel|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 {{intel|turbo boost}} frequency of up to 3.9 GHz.

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


== Cache ==
{{main|intel/microarchitectures/cascade lake#Memory_Hierarchy|l1=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.
