What is “Raspberry Pi 4B”? It is the 4th generation of the Raspberry Pi series of single-board computers (SBC) that can be consider to have single-handedly restarted the enthusiast computer revolution of the 1980s. Selling millions of units per year, it is the best selling UK computer and used far … Read more…

What is this “AlderLake-E”? After considering whether the recently released AlderLake (ADL) would have been better with 10 big/P(erformance) Cores and AVX512 rather than hybrid – someone asked why not the other way round? Why not just use LITTLE/E(fficient) Atom cores and no big/P cores? Note that Intel had such … Read more…
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…
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…

We are pleased to release R2x (version 31.25) update for Sandra 20/21 with the following changes: Sandra 20/21 Press Release Benchmark Support, Updates & Fixes CPU Scientific Benchmark: greatly improved AVX512 GEMM (SGEMM, … Read more…
What is “RocketLake”? It is the desktop/workstation version of the true “next generation” Core (gen 10+) architecture – finally replacing the ageing “Skylake (SKL)” arch and its many derivatives that are still with us (“CometLake (CML)”, etc.). It is a combination of the “IceLake (ICL)” CPU cores launched about a … Read more…
What is AVX512? AVX512 (Advanced Vector eXtensions) is the 512-bit SIMD instruction set that follows from previous 256-bit AVX2/FMA3/AVX instruction set. Originally introduced by Intel with its “Xeon Phi” GPGPU accelerators – albeit in a somewhat different form – it has finally made it to its desktop CPU lines with … Read more…
