Mythical Intel 12th Gen Core AlderLake 10C/20T big/P Cores (i11-12999X) – AVX512 Extrapolated Performance

CPU Neural Networks Benchmark

What is this “AlderLake-X”? ADL has now been launched – with AVX512 disabled: but, for the moment, it is possible to enable AVX512 on some boards; at least until the next microcode update. Some users have managed to benchmark ADL with AVX512 enabled (only big/P Cores enabled, LITTLE/E Atom cores … Read more…

big/Performance Core Performance Analysis (Intel 12th Gen Core AlderLake (i9-12900K))

What is “AlderLake”? It is the “next-generation” (12th) Core architecture – replacing the short-lived “RocketLake” (RKL) that finally replaced the many, many “Skylake” (SKL) derivative architectures (6th-10th). It is the 1st mainstream “hybrid” arch – i.e. combining big/P(erformant) “Core” cores with LITTLE/E(fficient) “Atom” cores in a single package. While in … Read more…
