Intel® Smart Cache Technology
The Intel® Smart Cache Technology is a shared Last Level Cache (LLC).
- The LLC is non-inclusive.
- The LLC may also be referred to as a 3rd level cache.
- The LLC is shared between all IA cores as well as the Processor Graphics.
- For P Cores The 1st and 2nd level caches are not shared between physical cores and each physical core has a separate set of caches.
- For E Cores The 1st level cache is not shared between physical cores and each physical core has a separate set of caches.
- For E Cores The 2nd level cache is shared between 4 physical cores.
- The size of the LLC is SKU specific with a maximum of 3MB per P physical core or 4 E cores and is a 12-way associative cache.
