Intel 14th Gen Core RaptorLake-Refresh (i7 14700K(F)) Review & Benchmarks – Hybrid Top-End Performance

What is “RaptorLake-Refresh”? It is the “next-generation” (14th gen) Core architecture, refreshing the current “RaptorLake” (13th gen) and thus the 4th generation “hybrid” (aka “big.LITTLE”) arch that Intel has released. As before, it combines big/P(erformant) “Core” cores with LITTLE/E(fficient) “Atom” cores in a single package and covers everything from desktops, … Read more…

AVX10: A big improvement for x64 vectorisation but it’s not ARM SVE

Intel Logo

What is AVX10? It is a unification of current AVX (Advanced Vector eXtension) instruction sets (ISA) into a new version-based standard that is width-independent (i.e. applies to any width from 128, 256 and 512-bit). This allows different CPU cores (e.g. Atom, Core, Xeon, etc.) to use the same instruction set … Read more…

APX (Advanced Performance eXtensions): Talk in a decade or so

Intel Logo

What is APX? It is a future update to the x64 (EM64T/AMD64) architecture (ISA) by Intel called “Advanced Performance eXtensions” that proposes: 32 vs. 16 64-bit general purpose registers (GPP) [aka 2x current] 3-operand instruction format conditional (aka predicated) instructions optimised register save/restore instructions As it is a somewhat fundamental … Read more…

What Intel needs is SVE-like variable width SIMD-AVX to solve hybrid problem

Intel Logo

What are AVX, AVX512? AVX or “Advanced Vector eXtensions” is a family of SIMD instructions on x86/x64 that have expanded the old SSE/2 (Streaming SIMD Extensions) that themselves have extended/expanded the original SIMD x86 instruction set: MMX (Multi-Media eXtensions). AVX2 increases the width to 256-bit while AVX512 increases the width … Read more…

big/LITTLE cores Performance Analysis – AlderLake to RaptorLake and beyond

What are “AlderLake”, “RaptorLake”? It is the current (12th gen) Core architecture – soon to be replaced by “RaptorLake” (RPL 13th gen) – that replaced the short-lived “RocketLake” (RKL “real” 10th gen aka ICL) that finally replaced the many, many “Skylake” (SKL) derivative architectures (6th-10th “fake” gen).
