Cache in Intel® Xeon® W-11000E Series Processors

This topic describes the cache for each processor, including Level 1 (L1) cache, Level 2 (L2) cache, and Level 3 (L3) cache (also referred to as last-level cache or LLC).
For L2 and L3 caches, the sizes of each cache and cache way are also shown. You may need this reference when using cache allocation tools.

Intel® Xeon® W-11865MRE Processor

The processor has eight cores and three levels of cache. Each core has a private L1 cache and a private L2 cache. All cores share the L3 cache.
Each L2 cache is 1,280 KiB and is divided into 20 equal cache ways of 64 KiB.
The L3 cache is 24 MiB and is divided into 12 equal cache ways of 2 MiB.

Intel® Xeon® W-11555MRE Processor

The processor has six cores and three levels of cache. Each core has a private L1 cache and a private L2 cache. All cores share the L3 cache.
Each L2 cache is 1,280 KiB and is divided into 20 equal cache ways of 64 KiB.
The L3 cache is 12 MiB and is divided into 8 equal cache ways of 1,536 KiB.

Intel® Xeon® W-11155MRE Processor

The processor has four cores and three levels of cache. Each core has a private L1 cache and a private L2 cache. All cores share the L3 cache.
Each L2 cache is 1,280 KiB and is divided into 20 equal cache ways of 64 KiB.
The L3 cache is 8 MiB and is divided into 8 equal cache ways of 1 MiB.

Intel® Xeon® W-11865MLE Processor

The processor has eight cores and three levels of cache. Each core has a private L1 cache and a private L2 cache. All cores share the L3 cache.
