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…
