Cobalt is based on Arm CSS model, so it's Neoverse series probably N2 (based on 128 core count). AWS Graviton 2/3 is N1/V1, and Nvidia Grace is V2. Ampere Altra is N1 and the new Ampere One is publicly unknown.
Several Chinese companies also develop chips based on N2, like Alibaba T-head and ZTE Sanechips. I worked on software tunings for both of them. It's good to see more and more Arm chips.
