> Nvidia GB200 does not refer to a single gpu, Nvidia’s naming scheme is very confusing. Considering past gpus were called H100, H200 etc, I thought GB200 would just be a newer GPU, but it does actually refer to their 30+ gpu rack scale systems.

It's even more confusing than that :)

    GB200 = 1 CPU + 2 B200 GPUs (packaged together)

    NV72 = A rack of 72 B200 GPUs (or 32 GB200 superchips)

Think of GB200 as something like Apple's 'Ultra' chip. Not exactly, but similar. They fuse the chips together with a very fast interconnect (connection).
