The numbers look amazing.
Can you comment on how difficult it was to achieve this, and what the relative advantages b/w cards ? AFAIR, AMD cards were not not deemed competitive with Nvidia in DL space largely because of the amazing job Nvidia pulled off with CUDNN and its conv. kernels.
LLMs etc. OTOH doesn't really depend on convolutions (atleast the pure transformer bits), and instead depends a lot more on plain old GEMM + low-bit float/int compute.
