In the README, it says:

> Important! Please don’t expect peak performance without fine-tuning the hyperparameters, such as the number of threads, kernel and block sizes, unless you are running it on a Ryzen 7700(X). More on this in the tutorial.

I think I'll need a TL;DR on what to change all these values to.

I have a Ryzen 7950X and as a first test I tried to only change NTHREADS to 32 in benchmark.c, but matmul.c performed worse than NumPy on my machine.

So I took a look at the other values present in the benchmark.c, but MC and NC are already calculated via the amount of threads (so these are probably already 'fine-tuned'?), and I couldn't really understand how KC = 1000 fits for the 7700(X) (the author's CPU) and how I'd need to adjust it for the 7950X (with the informations from the article).
