I just noticed that the bars appear to be wider than the last graph. Any idea what might be the cause of it? Perhaps because more tasks have been crunched since the last plot?

Believe the bars show variance. So larger sample size.

New scan includes early results for the GTX 1660 Ti -- only 14 hosts so there's more variance but it's looking very good.

Nice graphs,
Thanks.

The top #2 is doing about 6000 cr/hour per each one RTX2080Ti.
I just wish those easy to calculate numbers would be plotted with red X on the chart too. My own (#3) mix of 2 GTX1080, one 1080Ti and a TITAN V is a hard one to plot so I'm not asking to do that.

I know that plotting bigger numbers to the graph would need a huge readjustment of the horizontal axis.

Thanks anyway.

I'd really like blue/green/gold bars to show NV special app performance per hour and per advertised watt for each GPU type that have any data in the DB. That way people could decide what to buy for Windows and what to buy when planning to build a (compute only?) Linux rig.

I think Shaggy can't automate recognition of the CUDA special sauce.

I would be willing to create a text file of system ids of "all" or at least a lot of the special sauce users. Surely we have enough running them to get a good baseline. Then the trick would be to clone/create a new script that extracted only the systems on "the list".

Basically on par with the GTX 1080, and the RTX 2060 is on par with the GTX 1080Ti. Very good indeed.

I haven't looked. Is the price of a Gtx 1660 Ti at or lower than the price of a used gtx 1080 Ti? I am ignoring operational cost.

Based on a quick perusal of used eBay prices of the 1080 Ti, the 1660 TI is half the price.

there's too much variance with the stock apps due to all the different settings people run.

i've compared several models manually by watching the performance of many hosts with various cards with the special app, which has MUCH less variance since there's really only one switch you can play with (the nobs argument).

hierarchy is roughly this:
Titan V
2080ti
2080
2070 ~ 1080ti
2060 ~ 1080
1660ti ~ 1070ti
1660 likely to be around a 1070, but i haven't looked.

I'm in the process of swapping my 1080ti's to 2070s to save on some power. they are almost identical in speed.

As a programmer I'm sure that you're familiar with Amdahl's law; making the app 3x faster for a dozen users is insignificant compared with making the app faster for the 90,000 other active users volunteering for the project. Please stop asking me to show how much faster your code is on my graphs until it's an official app that everyone can use.

I was one of those who ask, it's your app & your choice, we all need to respect that of course, just was unaware of that. Will not ask again in the future. Please forgive me.
Just not understand the second part, there are some misunderstanding, the Linux apps are available in the same site as the Lunatics are, so anyone could use.

New this scan: NVIDIA GeForce RTX 2060's with excellent credit/watt and excellent performance.

There were some GTX 1660 Ti's in the scan but not quiet enough to qualify. I'll re-scan in a few weeks and maybe there'll be enough by then.



I keep running across (gamer) reviews that claim a Gtx 1070 is so close to being a Gtx 1070Ti that you should buy the Gtx 1070. I know, on the used market at least, that there is $70- difference in price. Anyone have an opinion?

I am always disappointed that my 1070Ti's performance is closer to the 1070 than it is to my 1080's.

Even though it only has one less SM compared to the 1080 and 4 more SM's than my 1070's

The price of a gtx 1070 (used) vs. gtx 1070Ti on eBay is $80-$100 less. Are there any other markets where I can reliably get one (or more) cheaper?

Just found some used gtx 1070's on eBay for $88, with a brand name (if they don't offer a brand beyond Nvidia, it is usually a scam offer), offered from the US. So I ordered 2.

New this scan, Radeon RX 590, GeForce GTX 1660 Ti, and GeForce RTX 2060: the 1660 Ti looks to be a new leader in performance/watt and the 2060 looks like an excellent economy option!

Thanks for the updated charts and stats, Shaggie76. I have my sights set on the 2070 as the best compromise to replace the 1070's.
