Depending on the algorithm, it can also matter how much cache(L1/L2/L3) the GPU has. VRAM is generally only important for knowing how many hashes you can load in 1 shot and the different VRAM types and configurations will be more algorithm specific like cache and not so easy to compare. Depending on the generation, you also care about architectural differences such as added/missing instructions and changes to the computing pipelines. So really, there is no simple answer to "what matters most to hashcat" and it is highly dependent on what algorithm you are running and what attack.

To cover some other topics that have come up briefly in this thread:
Yes, the 2080Ti is probably the best overall performance per dollar with it's current USED market price.
If you are buying new GPUs, the 4090 is _by far_ the best GPU you can buy AND is also the best _deal_ as well. The 4090 offers the best overall performance, the best performance per watt, and even the best performance per dollar of any new GPU, assuming you can get one down near the base MSRP. Obviously purchasing at MSRP has been a problem, so it may not be the best performance per dollar in the "real world" but it remains so on paper. It may seem unreasonably priced to some, but it should really only take 1 look at the actual performance to change that view.
