You haven’t said what are you comparing the `AMD 3900x` to.

But generally speaking, it will be faster than any Intel CPU with less cores which doesn’t have `AVX512` for Multi Threaded Linear Algebra.

It will be also a decent CPU for single threaded operations yet Intel has higher frequency CPU’s which will beat it on those tasks (Probably in the 3-10% range).

If you use it with MKL, remember to use the [Acceleration of Intel MKL on AMD Ryzen CPU’s](https://discourse.julialang.org/t/31287) trick. Then you’ll get the best BLAS performance out there for non `AVX512` 12 cores CPU.
