Thankfully the content is actually provided by us without any sponsorship! We ran into a memory bandwidth problem on one of these devices, wrote some small tests for it and ran it on the other devices as well. Indeed tho, the AMD gpus do seem to have extremely linear cache performance.

Full disclosure: I do run the company behind Evolve.

Thanks for this article. Let me know if you want some CDNA / MI300x to play with. Happy to donate compute time to see what you can come up with.
