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.

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.

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.

Noise

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.

    At 280$ for a Vega 56 with 3 games, it is brainless and one of the best value as of late. Can't wait for Navi to disrupt even more this overdue stagnant market. Reply

    Yes, it will be a new black hole in AMD quarters if the production cost/performance is the same as the old GCN line...
    You see, selling as HBM monster like Vega for that price simply means that the project is a compete flop (as it was Fiji) and nvidia can continue selling its mainstream GPU at the price they want despite the not so good market period.

    Final Fantasy XV is another game gimping AMD due to gameworks implementation. Reply

    They disable those before benchmarking. From the article: "For our testing, we enable or adjust settings to the highest except for NVIDIA-specific features" Reply

    All games gimp nvidia s their engine is written for the consoles that mount obsolete AMD HW. Reply

    It's hardly difficult to add in a bit of special slowdown sauce for the "PC" versions. Reply

    This is such a joke. Vega 56 is now the same price and out performs this terrible product, and the 1070 (AIB versions) performs similarly enough that the 1660ti has no real place in the market right now. Nvidia is a greedy terrible company. What a joke. Reply

    I followed your advice and bought a Vega56 instead of a 1660Ti and now my power supply has been making those weird noises animals make wen they're suffering and need help what do I do? Reply
  • Cooe - Friday, February 22, 2019 - link

    Fanboy nonsense alert!!! Unless you bought your power supply at a Chinese flea market, ignore this dude.

    (Granted there are totally cases where you'd want something like a 1660Ti over a V56 for efficiency reasons [say ultra SFF], but this guy's spitting nonsense)

    My point
    ========
    Your Head

    The V56 uses ~200w nominally depending on your choice of settings, in the detailed Tom's review it goes as low as 160w at the most minimum performance level and as high as 235w depending on the choice of power BIOS. The 1660Ti is then shown to use ~125w in BF1 and (assuming Tom's tested the V56 performance on stock settings) Anand's BF1 test shows a 9FPS lead (11%) over the 1660Ti. I'll trade that 11% performance for 40% less (absolute scale) power usage any day - My PSU ain't getting any younger and "lol just buy another one" is dumb advice dumb people make.

    Happy now?
