Interesting, would be nice to expand this to other cpus, and more features of a view into the cores. I know my current amd has 2 ccds, and 1 ccd is a tad slower according to amd ryzen master learning. But theres no fancy graphs.

For other platforms there is already https://github.com/nviennot/core-to-core-latency

This project works around a limitation in MacOS, namely lack of thread pinning, and makes it possible to do it without Asahi Linux, and without using custom MacOS kernel extensions and disabling security features.
