Are there any compatibility problems with Ryzen CPUs?
Mathematica 14.3 system requirements does not mention any CPU related limitations for Windows
THank you. That’s reassuring. I’m shopping for a refurbished laptop and ones with Ryzen processors seem to perform faster than those with Intel Core chips in the same price range.
Mathematica uses Intel’s Math Kernel Library (MKL). Intel puts a lot of work into optimizing the MKL for Intel processors. It’s unclear whether it puts in the same effort for rival CPUs. Years ago, it seemed clear that it didn’t. Here’s a recent blog post reporting some plusses and minuses:
Unfortunately, I am not an expert on such low-level computing issues, and I have little confidence in judging whether a source is reliable. There is also the issue of which version of MKL Wolfram uses. I don’t know the differences between versions of MKL, so I cannot comment further.
