Intel Raptor Lake-S Cache Sizes Confirmed in Blurry CPU-Z Screenshot: 68MB L2+L3
Back in January, we heard the first reports of Intel significantly increasing the on-die cache sizes on its 13th Gen Core "Raptor Lake-S" desktop processor, with the sum total of L2 and L3 caches on the silicon being 68 MB. A CPU-Z screenshot from the same source as the January story, confirmed the cache sizes. The "Raptor Lake-S" die in its full configuration features eight "Raptor Cove" performance cores (P-cores), and sixteen "Gracemont" efficiency cores (E-cores), making it a 24-core/32-thread chip.
Each "Raptor Cove" P-core features 2 MB of dedicated L2 cache even in its client variant, as previously reported, which is an increase from the 1.25 MB L2 cache of the "Golden Cove" P-cores on "Alder Lake-S." The sixteen "Gracemont" E-cores are spread across four E-core clusters, just like the eight E-cores of "Alder Lake-S" are spread across two such clusters. The four cores in each cluster share an L2 cache. Intel has doubled the size of this L2 cache from 2 MB on "Alder Lake" chips, up to 4 MB. The shared L3 cache on the silicon has increased in size to 36 MB. Eight P-cores with 2 MB each, and four E-core clusters with 4 MB, each, total 32 MB of L2 cache. Add this to 36 MB of L3 cache, and you get 68 MB of L2+L3 cache. Intel is expected to debut "Raptor Lake" in the second half of 2022 alongside the 700-series chipset, and backwards compatibility with 600-series chipset. It could go down as Intel's last client processor built on a monolithic silicon.

But the competition has 100MB cache on a 8core CPU, and maybe 200MB on a 16 core
Good luck going that route
14th gen, however...EMIB has a lot of promise to live up to. Can't be as bad as just running traces across the substrate though ;)
Amusingly, the glue remark only really fits intel's own tech, so calling substrate Fabric links "glue" both shoots themselves and also gives AMD more credit than it deserves......way too many counterproductive PR choices from intel in 9th-10th gen years
In 2022-2023? Probably not.
This shit should be marked as a low value post
That being said: AMD's 96MBL3 for a single thread is still far more than all of this L3 combined. On the other hand, AMD's default chips only have 32MB L3 cache, so Intel very possibly has a value-argument, depending on how cheap this chip here is manufactured.
My comment is valid, go look in most Intel threads and see the low brow childish crap. Maybe I should do the same in AMD threads. Guess what would happen, some double standards here for sure.
The glue comment was crap as mussels pointed out when a monolith has no glue, so was the usual childish shit thrown in most Intel threads.
Whatever. I don't see intel users posting shit in every AMD thread. Just wait till Intel is back in front. TPU will be a different place.
I can do 32GB kit 4800MHz already on my old tech DDR4 kit under RKL!
The way the world's economy is going atm, I'm not optimistic.
