Power, Temperature, and Noise

As always, we'll take a look at power, temperature, and noise of the GTX 1660 Ti, though as a pure custom launch we aren't expecting anything out of the ordinary. As mentioned earlier, the XC Black board has already revealed itself in its RTX 2060 guise.

As this is a new GPU, we will quickly review the GeForce GTX 1660 Ti's stock voltages and clockspeeds as well.

NVIDIA GeForce Video Card Voltages
Model Boost Idle
GeForce GTX 1660 Ti 1.037V 0.656V
GeForce RTX 2060 1.025v 0.725v
GeForce GTX 1060 6GB 1.043v 0.625v

The voltages are naturally similar to the 16nm GTX 1060, and in comparison to pre-FinFET generations, these voltages are exceptionally lower because of the FinFET process used, something we went over in detail in our GTX 1080 and 1070 Founders Edition review. As we said then, the 16nm FinFET process requires said low voltages as opposed to previous planar nodes, so this can be limiting in scenarios where a lot of power and voltage are needed, i.e. high clockspeeds and overclocking. For Turing (along with Volta, Xavier, and NVSwitch), NVIDIA moved to 12nm "FFN" rather than 16nm, and capping the voltage at 1.063v.

GeForce Video Card Average Clockspeeds
Game GTX 1660 Ti EVGA
GTX 1660 Ti XC
RTX 2060 GTX 1060 6GB
Max Boost Clock
Boost Clock 1770MHz 1770MHz 1680MHz 1708MHz
Battlefield 1 1888MHz 1901MHz 1877MHz 1855MHz
Far Cry 5 1903MHz 1912MHz 1878MHz 1855MHz
Ashes: Escalation 1871MHz 1880MHz 1848MHz 1837MHz
Wolfenstein II 1825MHz 1861MHz 1796MHz 1835MHz
Final Fantasy XV 1855MHz 1882MHz 1843MHz 1850MHz
GTA V 1901MHz 1903MHz 1898MHz 1872MHz
Shadow of War 1860MHz 1880MHz 1832MHz 1861MHz
F1 2018 1877MHz 1884MHz 1866MHz 1865MHz
Total War: Warhammer II 1908MHz 1911MHz 1879MHz 1875MHz
FurMark 1594MHz 1655MHz 1565MHz 1626MHz

Looking at clockspeeds, a few things are clear. The obvious point is that the very similar results of the reference-clocked GTX 1660 Ti and EVGA GTX 1660 Ti XC are reflected in the virtually identical clockspeeds. The GeForce cards boost higher than the advertised boost clock, as is typically the case in our testing. All told, NVIDIA's formal estimates are still run a bit low, especially in our properly ventilated testing chassis, so we won't complain about the extra performance.

But on that note, it's interesting to see that while the GTX 1660 Ti should have a roughly 60MHz average boost advantage over the GTX 1060 6GB when going by the official specs, in practice the cards end up within half that span. Which hints that NVIDIA's official average boost clock is a little more correctly grounded here than with the GTX 1060.

Power Consumption

Even though NVIDIA's video card prices for the xx60 cards have drifted up over the years, the same cannot be said for their power consumption. NVIDIA has set the reference specs for the card at 120W, and relative to their other cards this is exactly what we see. Looking at FurMark, our favorite pathological workload that's guaranteed to bring a video card to its maximum TDP, the GTX 960, GTX 1060, and GTX 1660 are all within 4 Watts of each other, exactly what we'd expect to see from the trio of 120W cards. It's only in Battlefield 1 do these cards pull apart in terms of total system load, and this is due to the greater CPU workload from the higher framerates afforded by the GTX 1660 Ti, rather than a difference at the card level itself.

Meanwhile when it comes to idle power consumption, the GTX 1660 Ti 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.

As for the EVGA card in its natural state, we see it draw almost 10W more on the dot. I'm actually a bit surprised to see this under Battlefield 1 as well since the framerate difference between it and the reference-clocked card is barely 1%, but as higher clockspeeds get increasingly expensive in terms of power consumption, it's not far-fetched to see a small power difference translate into an even smaller performance difference.

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.


Idle GPU Temperature

Looking at temperatures, there are no big surprises here. EVGA seems to have tuned their card for high performance cooling, and as a result the large, 2.75-slot card reports some of the lowest numbers in our charts, including a 67C under FurMark when the card is capped at the reference spec GTX 1660 Ti's 120W limit.


Idle Noise Levels

Turning again to EVGA's card, despite being a custom open air design, the GTX 1660 Ti 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. That's not an unreasonable tradeoff to make, but it's something I'd consider more appropriate for a factory overclocked card. For their reference-clocked XC card, EVGA could have very well gone with a less aggressive fan curve and still have easily maintained sub-80C temperatures while reducing their noise levels as well.

    What are you talking about? 3-5% Look at 960 vs 1060, right there in this article. About 100%! Reply

    Uhhh, Peewee?
    Get back to me when you compare the GTX 960 2GB specs to the 6GB GTX 1660 Ti specs (and the GTX 1060 3/6GB specs, as well).

    I know it's hard for you. It's tough to hit all those moving targets (and goal posts) ...

    Not impressive at all when the Vega 56 sold for the same price with 3 AAA games and offering 15%+ performances. Reply

    "Instead, AMD’s competitor for the GTX 1660 Ti looks like it will be the Radeon RX Vega 56. The company sent word last night that they are continuing to work with partners to offer lower promotional prices on the card, including a single model that was available for $279, but as of press time has since sold out. Notably, AMD is asserting that this is not a price drop, so there’s an unusual bit of fence sitting here; the company may be waiting to see what actual, retail GTX 1660 Ti card prices end up like. So I’m not wholly convinced we’re going to see too many $279 Vega 56 cards, but we’ll see."

    If Vega 56 becomes available for $279 regularly, then it will be a better deal. Right now, that price is only being offered on one model that you can't buy. The cheapest Vega 56 model on Newegg is $399 right now.

    You can get it for the same price, move on, it is the better deal. Also, expect higher price than MSRP from OEM creating special models with different coolers.

    And basically... RX 3080 is supposed to be between 250-300$ with Vega 64 + 15% performances. The interest of this card is going to be short lived.

    Yes, we know -- AMD's next card is always going to be the one to buy.

    But isn't it odd that by the time it stops being the "next" card and becomes the current card, suddenly it isn't that appealing anymore, folks like you immediately move onto the next "nest" card? Vega was the "next" card a year ago ...

    Where? I can't find one at that price anywhere, while there are several 1660TIs in stock at $279. Reply
  • Retycint - Tuesday, February 26, 2019 - link

    Not anymore, no. As far as I've checked, all the $279 Vega 56s have sold out at the moment, and with AMD stating that it's a temporary price cut, I'm not expecting anymore $279 Vegas to come our way. Reply

    You should try reading the actual article sometimes - once again 'jjj' with a pointless comment of the day. Reply

    It costs what a GTX1060 did at launch and offers GTX1070 performance which still costs more. Reply
