The rumour mill is indicating there are two, possibly three variants of the Nvidia GTX 1660. These will supposedly be officially announced on the 22nd of February.

The top of the line Ti model has 1536 CUDA cores, 1.5GHz base clock boosting to 1.77GHz and 6Gb of GDDR6 memory with a 192 bit interface. There seem to be some benchmarks floating around for it putting it very close to a 1070.

The second model is the non-Ti variant with 1280 CUDA cores, 1.55GHz base clock boosting to 1.785GHz and 6Gb of GDDR5 memory with a 192 bit interface.

The possible 3rd model is a 3Gb version of the non-Ti but not much is known about it.

The Ti variant has been spotted in retail packaging from EVGA using a 2.75 slot width cooler with a single fan. Palit has one with a 2 slot width cooler also single fan. There was also a Galax branded one. All seem to be short cards.

Saw them on Newegg today, several flavors around the $300 price point. The specs area is still missing a lot of detail on the one I looked at.

Interesting that it’s got an 8 pin power connector but the GTX 1060 had a 6 pin one. They’re both rated at 120 watts. Judging by the 3 slot cooler EVGA put on theirs I expect they get rather hot, or maybe they overclocked it a bit too much.

There doesn’t seem to be any mention of the non-Ti card, I expect they will come out later.

AMD meanwhile has dropped the price of the Vega 56 to compete, so if you’re in the market for Vega 56 cards now is the time to get them.

This is annoying, my main rig has a 1060 3Gb, which while fine for SETI, is not quite enough for my gaming.

So recently I was thinking of upgrading to a 1060 6Gb, then I see this!

https://www.amazon.co.uk/gp/offer-listing/B07NXVKDLW/ref=dp_olp_new?ie=UTF8&condition=new

Just really out of my price range but very tempting!!!

I gave in and ordered a Gigabyte GeForce GTX 1660 Ti 6GB Boost Graphics Card for £278.60 ($363.67 - €320.65) from a firm in Bradford, seemed like a good price.

Due here Tuesday.

I saw 2 benchmark reviews of the GTX 1660Ti and the Vega 56 and the 1660Ti beat the Vega hands down. Also, if I remember correctly, the Vega 56 gets really hot and crashed in 2 benchmarks. The RTX 2060 was the only card to beat the GTX 1660Ti. I believe the GTX 1060 (Ti maybe) was the 4th card used. The Vega 56 beat it once, then was 4th in all other benchmarks, except the 2 that it crashed.

Have a great day! :)

The articles I have read seem to think a gtx 1070 would be competitive (in performance) with the Gtx 1660.

I also thought I read a benchmark article that said that some of it's benchmarking results were inconsistent with other results (spike in performance).

Yes, more or less, a 1660ti is on par with a 1070 for games performance.

The EVGA 1660TI card tested was running stock reference clocks. It is however rated at 130W TDP budget which is 10W more than reference by having a higher power limit. The 3 slot cooler is the just the outcome for producing a short form card for mini cases. It has the same surface area as the standard 2 slot, two fan cards.

It seems EVGA will have three versions of the 1660Ti according to their website.

The XC and XC Black have the 3 slot cooler with a single fan. XC Black boosts to 1770 MHz and the XC boosts to 1845 MHz. Both have 6 power phases.

The XC Ultra is longer with a dual slot cooler and dual fans. The XC Ultra boosts to 1860 MHz and has 8 power phases.

People at GPUGRID tell me their application can't make use of Turing and Volta processors. But what is Volta? I knew only Maxwell, Pascal, and Turing.

I believe that was the Titan V
Quote from Wikipedia

The first graphics card to use it was the datacentre Tesla V100,... It has also been used in the Quadro GV100 and Titan V. There were no mainstream GeForce graphics cards based on Volta. Volta was succeeded by the Turing architecture.

I wanted to try a benchmark program but cant find a new one yet.

GPUZ is to old as well



PS Won't be crunching much till later as I am about to take it for a test drive in post apocalyptic Appalachia in Fallout 76

It's a feature of the CUDA SDK. Older versions always report the memory as 32bit integer. OpenCL will report the memory size correctly.

GPU-Z should be update pretty shortly to recognize the GTX 1660 Ti. They are always pretty quick with updates. You might want to try Geekbench 4 Compute tests.
https://www.geekbench.com/

There are already test results filed for the GTX 1660 Ti.
https://browser.geekbench.com/opencl-benchmarks
and is it landing between the GTX Titan Xp and the Radeon Vega Frontier Edition.

Well it has been crunching OK overnight, thought I would do a quick "non scientific" look at the figures.

The 1660 replaced a 1060 and the 970 is in my other machine.

I have done a quick average of the last 20 tasks done by my three cards (not including AP or shorties) and these are the times:

GTX-970 - 6.4 minutes/task

GTX -1060 - 7.3 minutes/task

GTX-1660 - 4.5 minutes/task

Also here is a comparison of GPU-Z on the 1660 and the 970 while crunching (the 1060 is currently homeless)



Both are as they came no tweeks or O/C by me though the 1660 is apparently factory O/C

The interesting thing is the power consumption, 92 watts verses 125 watts.

As for gaming it is superb, my current game is online and I have had problems with low fps in busy places, last night I saw a solid 60 fps most of the time with just a few places dropping to the mid 40's.

I am hoping to put the spare 1060 into the same machine as the 970, as it has the bigger PSU. It will be on a riser as there is no room. I will see how it goes.
