nvidia doesn’t need x86, they’re moving forward on aarch64 and won’t look back. For example, one of the headlines from CUDA 13 is that sbsa can be targeted from all toolkits, not as a separate download, which is important for making it easy to target grace. They have c2c silicon on grace for native host side nvlink. They’re not looking back.

They're clearly looking back though, investing in Intel and announcing quite substantial partnerships. Maybe they're not looking back for technical reasons, but they are looking back.
