| No, that's not the only thing. 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)
