If it's a first gen Titan card that you have (Kepler) then the Executable won't even work in Linux either.
Maxwell gen works! Kepler is earlier than Maxwell..

It is. His completed WUs list CC 3.5. Looks like the first Titan on Maxwell was the Titan X

I think he can run zi3v though.

Yes he can run TBar's CUDA60 zi3v special app on that CC3.5 capability card.

How is the speed on z3iv compared to those releases these days?

Have anyone tried it?

Regarding zi3v application performance...
I've done benchmarks in the past, whenever I made an upgrade to the appclications, so digging back a few months here are the figures I was able to find with regard to "zi3v" vs. other apps.
I will switch to -code- format to make the column alignment better...
workunit type                                        10jn08ad.        22dc08ab.         blc13.            blc14.
     times in seconds
app type
x41p_zi3v...cuda90                                  164                    84                   207                 212
opencl_nvidia_SoG                                    372                  219                  453                 463
x41p_V0.97b2...cuda91                               154                     69                  129                  132
opencl_nvidia_sah                                   383                  224                  515                   526

(...Oh, well... still didn't get nice columns like I wanted.)
Your mileage may/will vary. The workunits were chosen more or less at random with some intent to get different run times but to avoid overflow and noise bomb instances. The relative ranking among apps is consistent. (These were benchmarked on GTX-1060, one task at a time, with all other CPU activity kept to just OS required jobs. Linux 4.13 kernel. Ryzen 1700.)

I ran a scan over night and there aren't enough SUPER cards in circulation to qualify yet so the results are more or less the same as before. I'll do another scan in a week or two.

The Seti servers themselves think there are enough Super cards already if you look at the GPU models list. The Windows and Linux lists have Supers at the top.

But most of them are probably running Lunatics or the Special Application, from memory Shaggie's scans are of stock results only.

If I start shopping for Nvidia video cards to upgrade my gtx 1060 3gb/gtx 1070 mix what would give me "more production", cost less money to run AND be the cheapest to buy?

This could be a Black Friday/Cyber Monday or Christmas wish list.

More output means more powerful, cheaper means less powerful.
You need to decide just how much you can spend, look at how the present models compare for power consumption to your existing ones, and then see what falls in to that power usage/price limit range.


The present price/performance/power requirements king would probably be the just released GTX 1660 Super (not as good as a GTX 1660Ti for gaming, but just as good/maybe better in some cases for compute work).
The RTX 2060 Super has almost twice (about 1.8x) the performance of the GTX 1070, doesn't use a whole lot of power as far as video cards go, and it's reasonably priced compared to the models around it, for what it can do.

If I am reading it right, the Gtx 1660 Super would a very reasonable replacement for gtx 1060 3gb? (use less power, just as good or better performance?).

And the RTX 2060 would be your probable solution to replace gtx 1070's?

Less power and a step up in performance over a 1060.

It uses about 5W more, performance would probably be getting close to double for compute work.


And the RTX 2060 would be your probable solution to replace gtx 1070's?
RTX 2060 Super, about 20W extra for 1.8 times the performance. (The RTX 2060 only uses around 10W more than the GTX 1070. But it doesn't perform nearly as well as the RTX 2060 Super, and the super models are selling at pretty good prices compared to the non super ones, for their performance).
As you're prepared to play around with things, you could always limit them to the max power usage of the previous model, and still get a lot more work out of them than the models they are replacing.

Thank you Grant. That makes it easier to decide what I might get myself for Black Friday (if discounted enough) or for Christmas (if my power bill stabilizes like it is supposed to (I hope).

The RTX 2060 and 2070 SUPERs are included now -- some excellent performance for both of them depending on what you're looking for.

Also some Radeon Pro RX 500X series which don't seem particularly exciting.

This graph is getting too long -- maybe I should start culling the R7, R9, GTX 400 and GTX 500 cards?

Seems reasonable to me. Anything much below the equivalent performance of a gtx 750Ti is probably not going to used very much. I suppose you could use the gpu list from the website to slice things down too. If its not on the list, not very many are using it.

For the operating budget minded it really looks like that 1660Ti would be a great buy.
