There are reports that LinpackXtreme 1.1.5 does not work on Ryzen 9000 chips (e.g. here and here).
As Linpack was never intended to be run on AMD processors, it has to be manually... convinced to do so, and the binary included in LinpackXtreme 1.1.5 (

There are multiple Linpack versions in CoreCycler. The 2018.0.3.1 version has the same version number as the one that is used for LinpackXtreme's Intel binary, but the actual version for the AMD version is not being displayed in the file properties, so it's not entirely clear if that's a one to one replacement for AMD as well.
The other version could work as well, although at some time after the 2019 version, Intel has changed which parameters are accepted for the binary, so it may produce different results (I think 2021+ only uses AVX2 instructions, whereas LinpackXtreme is set up to try to activate only AVX).
