Comprehensive GPU performance list?

I would be confident they won't but would really recommend that you wait until someone with a 1660Ti reports their findings.  Hopefully, someone will respond - or one of the regulars might notice one as a `quorum partner' :-).

Sounds like a good option to me :-).

If max output for both purchase price and ongoing running costs is the main consideration driving your purchase decision, you should spend some time going through this thread.  There's a lot of reading but you'll get the full story, warts and all.

The author is a long time NVIDIA user who has made the transition to AMD.  He's a very careful and thorough person who was particularly keen on energy efficiency and good output for minimal/acceptable fan noise since the computers are in a 'living room' type environment.  He has documented his energy efficiency comparisons and he seems (on balance) quite pleased with the eventual outcome.  He's very clear thinking about what he wants and not at all a 'fan boy' of either brand.

His initial purchase was an RX 570, and he quickly followed up with a second one.  If they are still available at the 'post-crypto-mining-boom' low prices of around $US 140, one of those would make an excellent replacement for a 780Ti - 3x the output for less power.  He has documented his power consumption figures very thoroughly.  There's a lot to read and digest in his story, but it's worth it :-).

EDIT:  One other point I should mention.  All comments about GPU crunching at Einstein relate to the current long running (and stable) gamma-ray pulsar search app (FGRPB1G).  There is a new search on the horizon - a GPU search for continuous gravitational wave (GW) emissions from massive bodies like spinning neutron stars.  Up until now, GW searches have been 'CPU only'.  There is a new GPU app being tested and initial indications are that the performance will (initially) be rather poor when compared to that of the FGRPB1G app.  Performance should hopefully improve over time but it's quite unclear how long this might take and how different brands/models of GPUs might be affected.

The 'holy grail' for this project will be the first detection of continuous GW emissions so the non-credit die hard supporters amongst us will likely switch to the GW GPU search irrespective of credit reductions :-).   No doubt there will be a whole new round of discussions about the performance of the new GW app and which brands/models do best so you might like to think about that aspect as well :-).

Sure, and all the 'regulars' will understand that.  I get to approve profiles for new volunteers (or people returning after a lengthy absence) so I'm rather conscious of a significant group of people who might want to get a GPU once they see how much more productive that can be.  They are unlikely to fully understand just how project specific the performance can be.  They tend to be in a hurry and the beautifully and professionally laid out information at Seti is so compelling .... so why the hell bother with any further research of their own? :-).

I entirely agree for long term volunteers who keep up to date with what's happening at the various projects they support.  Apart from new/returning people who don't have that knowledge, the bulk of volunteers probably belong to the 'set and forget' group so these also won't necessarily understand the performance differences.  A short disclaimer is a polite way of reminding them they still should do their own research for any planned purchases.

In case you think otherwise, my post wasn't directed negatively at you at all, so I'm very sorry if it gave that impression.  I wasn't intending to 'lecture' you, although you may have thought I was.  It was really directed at people planning to jump on the GPU bandwagon without really understanding all the nuances.  After all, a thread entitled, "Comprehensive GPU Performance List" is bound to attract lots of inexperienced people wanting an instant fix :-).  I gave the examples for their benefit - not yours - since I know that you are fully competent to make your own judgements about these things.

I have 3 of that exact model, running since Nov 2017.  I also have others from Asus, Sapphire and Gigabyte and I haven't really noticed much difference in fan noise between any of them.  That's not really surprising since they all run in a room with forced ventilation driven by large (and noisy) industrial fans :-).  I've had no hardware issues with any of them.

Do a google search for 'nvidia coolbits' and you should find lots of hits.  I think there is even an ArchWiki entry describing how to set a number of things to do with frequency, voltage and fan control.  I don't use nvidia so I don't have specific information.  Some of the hits are bound to give you the details you need.

If you get no responses here, you could always try watching Shaggie's thread at Seti.  As a result of the new mention of the 1660Ti, you might find people announcing that they have or are getting one.  Maybe you might get lucky and find such a post where the owner might run it here as well.

I did a quick look and found one of these GPUs in this user's computer list.  Unfortunately it's Seti only.  As I was browsing, I think I saw a comment that the 1660Ti performs similarly to a 1070 (I think but I could be wrong).  If you browse enough posts, you may well be able to find such information.  If you look at how a 1070 performs at Einstein, you might get some basic idea of what a 1660Ti might do.  Of course, it would be much better to find one working here and to discuss it with the owner.

What Gary said.  Coolbits tweak is your friend.  Setting the xorg.conf file to have the coolbits option enables fan speed control, gpu core clock and memory clock speeds for Nvidia cards.  You then can use the Nvidia Settings application to control each card or run a script to set all your parameters before starting crunching for all cards.

sudo nvidia-xconfig --thermal-configuration-check --cool-bits=28 --enable-all-gpus

Thank you,

I'll read up a bit before I might burn the card.
