Nearly four years have passed since AMD launched their EPYC Milan-X processors with 3D V-Cache. When recently rearranging some servers in the lab and realizing the four year anniversary was coming up in March, curiosity got the best of me in wondering where the Linux performance and energy efficiency on Milan-X is now with the latest Linux software stack compared to the numbers when Milan-X launched back in March 2022.
