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 ... Intel raptor Lake Caches Confirmed through leaked CPU-Z screenshot
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.
Think i'll wait for Meteor Lake before I upgrade next. At least then it'd be a more substantial upgrade and on a new node too.
This is not Intel copying AMD cache, this has been in the pipe for a year or so and is just a regular step on the ladder. The only reason the number is high on this chip is because of the amount of E-cores. All those 24 cores are barely matching a 5950x for cache and a 5950 3D would be around 200mb cache.
I think it is. AFAIK, the K6 III was the first x86 CPU with L3 cache https://en.wikipedia.org/wiki/AMD_K6-III I remember the P4EE which used the same trick. L3 cache is what happens when CPU manufacturers have run out of usual ways to make their products faster!
at the moment there is little to no difference if you get decent DDR4 and nothing even really used PCIE4 fully. The one thing that's proven to give an increase in FPS (more cache) is purely an AMD thing
If you look at it that way, the 5800 3d could be considered a copy of Intel broadwell instead, because the cache is added on the side as extra compared to the previous design. The cache increase of the P cores of the raptor lake CPU is just a small step, it will take them multiple generations to reach AMD with that pace, if it was a copy they would have been much more agressive with the cache sizes. The E cores are the ones carrying a lot of the cache boost and AMD does not have E-cores.
the k6-3 had no on-chip l3. the K6-3 included its own L2 cache and repurposed the cache on the motherboard as L3, this cache was used as L2 on the K6-2. the P4EE was the first cpu with L3.
