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…

Intel 11th Gen Core RocketLake AVX512 Performance Improvement vs AVX2/FMA3

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…

AVX512-IFMA(52) Improvement for IceLake and TigerLake

CPU Multi-Media Vectorised SIMD

What is Sandra’s Multi-Media benchmark? The “multi-media” benchmark in Sandra was introduced way back with Intel’s MMX instruction set (and thus Pentium MMX) to show the difference vectorisation brings to common algorithms, in this case (Mandelbrot) fractal generation. While MMX did not have floating-point support – we can emulate them … Read more…

AVX512 Improvement for Icelake Mobile (i7-1065G7 ULV)

Intel Ice Lake

What is AVX512? AVX512 (Advanced Vector eXtensions) is the 512-bit SIMD instruction set that follows from previous 256-bit AVX2/FMA/AVX instruction set. Originally introduced by Intel with its “Xeon Phi” GPGPU accelerators, it was next introduced on the HEDT platform with Skylake-X (SKL-X/EX/EP) but until now it was not avaible on … Read more…

Intel Core i9 10980X (Cascade Lake) Review & Benchmarks – CPU 18-core/36-thread AVX512 Performance

Intel Skylake-X Core i9

What is “Cascade Lake (CSL-X)”? It is one of the 10th generation Core X-Series arch (CSL-X) from Intel – the latest revision of the “Skylake-X” (SKL-X) arch; it succeeds the older 9900 and 7900 X-Series for HEDT platform. Again, as on the desktop/mobile – it is not the “real” 10th … Read more…
