2022 Mac Studio (20-core M1 Ultra) Review
Above, we’re looking at parallel performance of the NASA USM3D CFD solver as it computes flow over a classic NACA 0012 airfoil section at low speed conditions.If this solver relies on matrix multiplication and uses the macOS Accelerate framework, you are seeing this speedup because M1 Macs have AMX matrix multiplication co-processors. In single precision GEMM, the M1 is faster than an 8 core Ryzen 3700X and a bit slower than a 12 core Ryzen 5900X. The M1 Pro doubles the GFLOPS of the M1 (due to having AMX co-processors for both performance core clusters). And the M1 Ultra again doubles the GFLOPs (4 performance core clusters, each with an AMX unit).Single-precision matrix multiplication benchmark results for the Ryzen 3700X/3900X and Apple M1/M1 Pro/M1 Ultra are here:https://twitter.com/danieldekok/status/1511348597215961093?s...
