[citation][nom]wiyosaya[/nom]FWIW - 2070 run BOINC WUs slower than a GTX 460.If you look at the poster's world BOINC position, he is the number 1 overall BOINC contributor in the world. Unfortunately, his computer stats do not give the details on which machines run what GPGPU. Since he has experience running various hardware in a virtual HPC environment, I tend to think that his opinion holds some weight.Personally, I think the argument here is similar to that of using a Quadro in a CAD environment as opposed to a consumer card. While I am sure there are scenarios where the pro cards excel as they do in large CAD models, I would not be surprised if those HPC scenarios are presently a small number of all possible scenarios as they are in CAD.Coming from a "pro" imaging software background, the software the company I worked for delivered to all users is the same - various users pay a premium to enable certain features - which is gravy to the manufacturer. As stated above, the silicon is the same; whether the "special treatment" given to the pro market is worth the extra cost is, ultimately, up to the end-user and their requirements.From the 2090 spec sheet, it has a passive cooler. Many GTX 590 boards offer active cooling which lessens the need for airflow management for a 590 solution.I am not sure how many of either one can run in a single box - and I am assuming that one would not run the 590s in SLI for a HPC scenario as SLI gives no advantage in an HPC scenario, AFAIK, for doing so.In my opinion, pro cards are not worth the extra expense. However, if you have the budget and your use case scenarios are such that Teslas give a proven advantage that justifies the extra expense, then Teslas would, of course, be the better choice.[/citation]
You're forgetting the already-mentioned double-precision performance – on consumer cards, it is far lower than on professional cards, and it is far more important than single-precision.
Also consider that the extra cost of professional cards is probably minimal compared to other expenses.
