Other characteristics of V100 that may be interesting to people buying GPUs for data centers:
- higher capacity GPU memory. 1080 has 8 GB, V100 has 16 or 32 GB.
- higher bandwidth GPU memory. V100 has HBM2 with a peak of 900 GB/s, 1080 has G5X with a peak of ~300 GB/s.
- ECC support.
- data center certification + warranty
(The geforce warranty covers normal consumer usage, like gaming, and does not cover datacenter use)
- availability of enterprise support contracts.
(If you are buying a ton of GPUs to put in a datacenter, you probably don't want to end up on the normal consumer support line when something goes wrong)
- fast fp64
There are probably others
Apart from one being a gaming product and the other being designed for computational tasks, they're a generation apart and have various small differences that may be quite relevant for individual tasks (such as V100 allowing twice the shared memory - 96 KiB - per thread block)
Took me quite a while to get my hands on a 3080.
I used this[2] site to keep an eye open for stock, as you can see it's pretty much empty now but I just checked every day and finally found one.

Wait what? Is it the only thing?
That sounds hard to believe: if true, using the open driver (Nouveau) instead of Nvidia's proprietary one would be a massive money saver for datacenters operators (and even if Nouveau doesn't support the features you'd want already, supporting their development would be much cheaper for a company like Amazon than paying a premium on every GPU they buy)
