One interesting thing from the Hopper announcement is that, according to
the Hopper white paper, Hopper supports CUDA compute capability 9.0. This isn't particularly surprising in itself, as A100 supported 8.0, and gaming Ampere chips support CUDA compute capability 8.6. What is interesting, though, is that Ada is launching after Hopper, and the leak suggests that Ada's compute capability version is 8.9 (ie SM89), which would be the first time that compute capability hasn't strictly increased with each new launch. For example V100 was 7.0, Xavier was 7.2, and Turing cards were 7.5, then A100 was 8.0, Ampere gaming cards are 8.6, and apparently Orin and Drake are 8.8 (although I can't find any public confirmation from Nvidia for Orin). This does further suggest that Ada is largely an enhanced version of Ampere on a new node, rather than a gaming twin of Hopper.
This isn't necessarily a bad thing for Ada, as the additional capabilities of 9.0 introduced in Hopper probably aren't of much use to gaming applications, but it is interesting in that it represents an increased level of separation between Nvidia's HPC and gaming architectures.
