The NVIDIA GeForce GTX 1660 Review, Feat. EVGA XC GAMING: Turing Stakes Its Claim at $219
by Ryan Smith & Nate Oh on March 14, 2019 9:01 AM ESTPower, Temperature, and Noise
As always, we'll take a look at power, temperature, and noise of the GTX 1660, though after having seen the GTX 1660 Ti in a similar if not identical design, we aren't expecting anything out of the ordinary. As mentioned earlier, we've seen the XC Black board with the GTX 1660 Ti not too long ago.
Using the same TU116 GPU as the GTX 1660 Ti, the voltages are unsurprisingly the same.
| NVIDIA GeForce Video Card Voltages | ||
| Model | Boost | Idle |
| GeForce GTX 1660 | 1.037V | 0.656V |
| GeForce GTX 1660 Ti | 1.037V | 0.656V |
| GeForce RTX 2060 | 1.025v | 0.725v |
| GeForce GTX 1060 6GB | 1.043v | 0.625v |
As for clockspeeds, the same broad points from the GTX 1660 Ti review apply. Clocks at +10W TDP and at reference 120W TDP are only slightly altered, and the trend of NVIDIA's conservative boost estimates continues.

Compared to the official average boost clock of the GTX 1660 Ti, the differences are also minor.
Power Consumption
Meanwhile when it comes to idle power consumption, the GTX 1660 falls in line with everything else at 83W. With contemporary desktop cards, idle power has reached the point where nothing short of low-level testing can expose what these cards are drawing.
All told, NVIDIA has very good and very consistent power control here. and it remains one of their key advantages over AMD, and key strengths in keeping their OEM customers happy.
Temperature
Noise
Turning again to EVGA's card, despite being a custom open air design, the GTX 1660 XC Black doesn't come with 0db idle capabilties and features a single smaller but higher-RPM fan. The default fan curve puts the minimum at 33%, which is indicative that EVGA has tuned the card for cooling over acoustics. But the curve is a little more forgiving at higher temperatures, and doesn't ramp up as much, reducing their noise levels significantly from the Ti XC Black.

1660 Ti power usage: more for GPU, less for GDDR6. 1660: less for GPU (due to 2 fewer SMs), but more for GDDR5. Hence why overall power usage for both is the same. What I still don't understand is why all of these cards, despite being rated to draw under 150W, come with 8-pin power connectors; 6-pin would make far more sense and would make them compatible with many older systems.Alistair - Friday, March 15, 2019 - link
They are still holding back. This would have been an incredible 7nm card. That's still what I want. Not interested.backpackbrady - Saturday, March 16, 2019 - link
amazing post ryan / nate!@# hoping you could answer a question beyond my knowledge for me. would the 1660 hardware-based encoder nvenc be at a disadvantage with the TU116 and GDDR5 changes? im not sure what effects the encoders performance. thank you very much for your time and knowledge. bradyHrel - Tuesday, March 19, 2019 - link
Suddenly Nvidia's pricing seems completely fair.Supercell99 - Thursday, March 28, 2019 - link
Chinese are done dumping after market GFX cards. Used market is drying upHrel - Saturday, March 30, 2019 - link
This is looking like one hell of a good card for the money and the market. Faster than the RX 580 and RX 590, priced like a cheap 590 or average 580, less power draw, runs cooler, includes Nvidias (frankly) superior software and drivers. So right now either the GTX1070 used, or the GTX 1660 new, 1070 should be about the same price even used. Only cheaper ones I found were crypto mining cards and F that noise.There are some technology differences but idk, you guys don't seem to go into great detail about the differences between GTX 1070 and GTX 1660 excluding game performance. Are there any notable DX features included in the newer card or is it just straight performance improvement?

I think a year or so from now I'll pick one of these up, either 1660 or ti, will depend on then current pricing.
