Intel's 13th Gen Core Raptor Lake-S desktop processor has 68 MB of L2 and L3 on-die caches. Raptor Lake-S" is a 24-core/32-thread processor with eight Raptor Cove performance cores and sixteen "Gracemont" efficiency cores.

As the screenshot will confirm, Each Raptor Cove P performance core has 2 MB of dedicated L2 cache, up from 1.25 MB on Alder Lake-S Gracemont has 16 E-cores in 4 clusters, while "Alder Lake-S" has 8 in 2 clusters. Each cluster's four cores share L2 cache. Intel quadrupled "Alder Lake" L2 cache from 2 MB to 4 MB. The chip's shared L3 cache is now 36 MB. Eight 2 MB P-cores and four 4 MB E-core clusters total 32 MB L2 cache. L2+L3 cache is 68 MB. Intel is expected to release Raptor Lake in 2022 with the 700-series chipset and 600-series backward compatibility. Intel Mainstream Desktop CPU Generations Comparison:

More cache the better i guess intel going amd route.

At 24/32, that to me suggests it will top out at 8 P-cores and 16 E-cores.
For desktop CPUs, I think that's fine, but I know people are going to gripe about this a lot.

The Intel approach seemed to deliver quite a decent level of performance, but strangely enough the power consumption wasn't that good in heavy multithreading work, even though the CPUs are loaded with the so called efficiency cores. It remains to be seen if that is something Intel is interested in changing in future gens.
