Value verdict

▸ Should you buy/upgrade?

H200 SXM5 adds 61 GB VRAM for +$34000 (309% premium). The real question is whether your workflow needs models that A100 80GBcan't run.

If yes — you want to run DeepSeek Chat V2.5 or similar — then the 61 GB is load-bearing, not luxury.

$ recommend → If you own a A100 80GB: wait. Prices drop, refresh cycles continue. If buying new: get the H200 SXM5 IF your budget allows AND you need the unlocked models.
