2022 Mac Studio (20-core M1 Ultra) Review
<i>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.</i><p>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).<p>Single-precision matrix multiplication benchmark results for the Ryzen 3700X/3900X and Apple M1/M1 Pro/M1 Ultra are here:<p><a href="https://twitter.com/danieldekok/status/1511348597215961093?s=21&t=2v6pZmDWSYGtShH61THtPA" rel="nofollow">https://twitter.com/danieldekok/status/1511348597215961093?s...</a>
