Power, Temperature, and Noise

With a large chip, more transistors, and more frames, questions always pivot to the efficiency of the card, and how well it sits with the overall power consumption, thermal limits of the default ‘coolers’, and the local noise of the fans when at load. Users buying these cards are going to be expected to push some pixels, which will have knock on effects inside a case. For our testing, we use a case for the best real-world results in these metrics.

Power

All of our graphics cards pivot around the 83-86W level when idle, though it is noticeable that they are in sets: the 2080 is below the 1080, the 2080 Ti sits above the 1080 Ti, and the Vega 64 consumes the most.

Idle Power Consumption

When we crank up a real-world title, all the RTX 20-series cards are pushing more power. The 2080 consumes 10W over the previous generation flagship, the 1080 Ti, and the new 2080 Ti flagship goes for another 50W system power beyond this. Still not as much as the Vega 64, however.

For a synthetic like Furmark, the RTX 2080 results show that it consumes less than the GTX 1080 Ti, although the GTX 1080 is some 50W less. The margin between the RTX 2080 FE and RTX 2080 Ti FE is some 40W, which is indicative of the official TDP differences. At the top end, the RTX 2080 Ti FE and RX Vega 64 are consuming equal power, however the RTX 2080 Ti FE is pushing through more work.

For power, the overall differences are quite clear: the RTX 2080 Ti is a step up above the RTX 2080, however the RTX 2080 shows that it is similar to the previous generation 1080/1080 Ti.

Temperature

Straight off the bat, moving from the blower cooler to the dual fan coolers, we see that the RTX 2080 holds its temperature a lot better than the previous generation GTX 1080 and GTX 1080 Ti.

Idle GPU Temperature

At each circumstance at load, the RTX 2080 is several degrees cooler than both the previous generation and the RTX 2080 Ti. The 2080 Ti fairs well in Furmark, coming in at a lower temperature than the 10-series, but trades blows in Battlefield. This is a win for the dual fan cooler, rather than the blower.

Noise

Similar to the temperature, the noise profile of the two larger fans rather than a single blower means that the new RTX cards can be quieter than the previous generation: the RTX 2080 wins here, showing that it can be 3-5 dB(A) lower than the 10-series and perform similar. The added power needed for the RTX 2080 Ti means that it is still competing against the GTX 1080, but it always beats the GTX 1080 Ti by comparison.

    Why would I want a feature like DLSS when current AA methods do the job fine and we can also just run at native, higher resolution anyway and not use any AA whatsoever?

    And why would anyone care about vaporware like RTRT?

    No DLSS, NO.

    Blur.

    Not capable of raytracing, just raytrace small parts of a frame on selected scenes on selected games...

    You must be joking right? What do we care if the price of manufacturing increased for Nvidia. We are mot supporters, we are clients. We don't have to support their pricing because WE ARE NOT SOCIOS! Let Nvidia reduce their costs by cutting the salaries of their CEOs and other wortless corporate officers. Then I will BUY their 2080Ti product, at the consumer-friendly price of €750 Reply

    Except for the fact that the non founders edition is $999, not $1200. And the GTX 1080ti released at $699 but for the better part of the past two years cost substantially more. Reply

    Then find one at that price, genius.

    3rd parties are OC their cards and offering additional cooling solutions, they will all be over the MSRP and close to the FE.

    Also, they use GDDR6... you didn't learn anything from Vega and HBM2?

    Agree the cost is ridiculous. I haven't paid it and won't. Got to many children to raise. I've never seen them at the above mentioned. Reply

    1080 Ti for $600, where, when? Reply

    So buy a 1080ti. For some the new features are worthy and boost perf quite massively making it truly worth it if those technologies are the new way forward. At worst, a good 25 games are already coming with NV's new tech. Many are huge titles most would like to play surely.

    Also as Hexus noted a while back, the price to make these things is just below MSRP. Note the small chip is as large as a titan, and the larger chips...WOW. That's a lot of transistors for a game card. Also apples vs. oranges here, as said by others 1080 etc can't do raytracing or dlss.

    27 games coming with NV tech. Will they look the same on 1080ti or less? NOPE. Will they be faster and BETTER looking on RTX...YEP. Value is in the eye of the beholder ;)

    The problem is, you just counted twice when you said "will they be faster and better looking on RTX".

    The absolute truth of it from what little we can glean so far (after the official launch!!!) is that you can have RTX effects /OR/ you can have your better performance, not both. That's a heavy caveat!

    It would be one thing if it were a proposition of waiting a couple of months for some amazing features that will knock your socks off and have few drawbacks. It's another to be paying over the odds for a card now to maybe get some cool stuff that will DEFINITELY run slower and at a lower res than you're used to.
