The number of cores matters less. Addressable threads matter more in many workloads. 16C/32T 7950X is as good in MT workloads as 24C/32T 13900K is, and Ryzen uses less power in those workloads.I wonder why AMD doesn't make the CPU as 8 Zen5 VCache cores + 16 Zen5c/4c cores.
Why not compete with Intel that way? They can still offer 16 full zen5 core CPUs and it would greatly differentiate the VCache variants from the regular.
7700X is 8C/16T. It competes against 13600K with 14C/20T. It has 6 cores less, but it is only 5% slower in MT workloads. 6 cores less for 5% less! Do you get the vibe?
Big cores+c cores+V cache is more complex combination that they are testing in labs. You will need to be patient for that.But that is also my point though, instead they should mix big zen vcache cores with little C cores so that the windows scheduler can more easily separate them just like they already do with Intel.
Once AMD first releases vanilla big cores+c cores, Windows scheduler will not have any problems, as c cores have the same instructions and HT, just less L1/L2/L3 memory. Those are simply smaller cores, but different than Intel's little cores. AMD's big and c cores both support HT and AVX512. So, 8+8 SKU will have 32 threads, unlike Intel's 24 threads on 8+8 cores. AMD did not want to go Intel's way with c cores and make them single-threaded because this creates more problems with execution of instructions. That's why Intel cancelled AVX512 on consumer big-little CPUs. AMD's version of efficient c-cores will be far more capable in MT workloads than little cores
Which two generations? Nonsense. The first SKU with c-cores will be Bergamo with 128 c cores, to be released this summer. The CPU is already in test systems of hyperscalers. It's the first ever product with 16-core chiplets, each with 8 core CCX.Sure but AMD is sitting on this "c" type core technology since 2 gens now and is not doing anything on the client segment with it. Intel is about to bring 8+32 cores to the market and AMD will remain with just 16 big cores which won't win either the single or the multi threaded benches. It will just be more energy efficient. I would like to see a 8 + 16 from AMD at some point.
Most advanced and complex technologies usually come to server space that needs it, and later trickle down consumer segment.
