In any case the push and pleasure of Nvidia’s Turing launch at Gamescom, there’s now lower than every week to go earlier than these shiny new GeForce RTX graphics playing cards are out within the wild. Subsequent Thursday on September 20, each the RTX 2080 and RTX 2080Ti will substitute the GTX 1080 and GTX 1080Ti as Nvidia’s prime canine bestest best graphics playing cards – and the good factor is I can now lastly inform you about all the opposite cool stuff they will do apart from their fancy ray-tracing reflection gubbins.
I nonetheless can’t speak about efficiency figures simply but – that may come subsequent week – however relaxation assured, real-time ray tracing isn’t the one factor that makes these playing cards stand out. There’s additionally DLSS, Nvidia’s nifty deep studying anti-aliasing tech that makes use of AI to rise up to double the efficiency of a GTX 1080. There’s additionally variable price shading, which lightens the load on the GPU even additional by simulating sure chunks of the surroundings and concentrating all of the element the place it’s wanted most, supplying you with much more efficiency and scrumptious frames per second. Then there’s the Nvidia Scanner for one-click overclocking, Ansel RTX for even prettier screenshots and an entire lot extra – all defined right here in (hopefully) non-techno jargon.
It’s all about velocity, velocity, velocity on this right here Turing practice, however will it’s sufficient to justify their big value? Right here’s all the things you’ll want to know, together with the RTX 2070, RTX 2080 and RTX 2080Ti’s worth, specs and release date, in addition to all the opposite tidbits I’ve gleaned from numerous builders and demo periods. Let’s go.

Nvidia Turing RTX 2080 specs
Mendacity on the coronary heart of the RTX 20-series is Nvidia’s Turing GPU. Borrowing a lot of the identical fancy gubbins as Nvidia’s skilled Quadro RTX playing cards, together with its RT Cores (or ray tracing cores), Tensor Cores (that are all to do with AI and deep studying bits and items) and Streaming Multi-processor (or SM processor, for brief), the RTX line is as a lot about new technological features as it’s about uncooked efficiency.
Accompanying the Turing GPU is a fairly hefty dollop of GDDR6 RAM. The RTX 20-series would be the first graphics playing cards on the earth to benefit from this tremendous quick reminiscence, beating AMD’s Navi GPUs nicely and really to the punch. With at the very least 8GB of the stuff at their disposal, this could undoubtedly assist raise the playing cards’ respective speeds in comparison with their instant predecessors. Right here’s how all of them form up in useful graph type:
I’m not going to fake to know what all these additional metrics truly imply, like Giga Rays and RTX (ray tracing) operations, as a result of even Nvidia have admitted they needed to invent new ones for Turing as a result of it’s simply so gosh-darned highly effective in comparison with the GTX 10-series’ Pascal GPU. As some extent of comparability, although, the Nvidia GeForce GTX 1080Ti can solely do 1.21 Giga Rays/second. That makes the RTX 2080Ti round 8x extra highly effective within the previous ray-tracing division.
When it comes to show outputs, every card may even help 8K resolutions at 60Hz with HDR enabled – on a single display, no much less because of their DisplayPort 1.4a prepared ports, in addition to 4K at 60Hz by way of their HDMI 2.0b outputs. They’re additionally able to help the brand new fancy USB-C tech, VirtualLink. This can be of specific import for VR customers, because it means the cardboard’s USB-C output will be capable of ship all the facility, show and all the info you could use a VR headset from a single connector.
Nvidia’s additionally hoping their Turing playing cards can be an interesting prospect for streamers, too, as they’ll be capable of encode 8K video at 30fps in HDR in actual time for the primary time, in addition to rise up to 25% bitrate financial savings when encoding with HEVC, and as much as 15% financial savings in H.264. 4K streaming will even develop into much more sensible, with Nvidia claiming you’ll get higher efficiency than a typical x264 encoding setting you may be utilizing immediately, with 1% dropped frames when streaming to Twitch at 4K utilizing a 40Okay bitrate, in comparison with 90% by way of x264, and 1% CPU utilization in comparison with x264’s 73% at 4K over a 40Okay bitrate.
Nvidia Turing RTX 2080 ray-tracing: what’s it and why ought to I care?
Primarily a bit of actually, actually fancy mild tech that makes shadows and reflections behave simply how they do in actual life, ray tracing is an enormous a part of what makes Turing so particular. It’s within the identify of the graphics card, in any case (RTX), and it’s not shocking Nvidia have targeted virtually all their consideration on it since their preliminary announcement.
It’s not correct, correct ray tracing such as you get in Pixar movies, all advised, however Nvidia’s AI boffins have just about given us the subsequent best factor – as my interview with Metro Exodus rendering programmer Ben Archard can attest. It’s value stating, although, that it’s nonetheless an additional function builders should help relatively than an inherent a part of the cardboard. Nonetheless, if even a fraction of video games find yourself wanting nearly as good as Nvidia’s Sol ray tracing demo under, I’ll be very joyful certainly.
In the meanwhile, there are only a handful of confirmed video games that shall be supporting the RTX 20-series’ ray tracing potential, however the demos I’ve seen thus far have all been slightly tasty wanting, from Shadow of the Tomb Raider‘s energetic Day of the Lifeless scene to Battlefield V‘s exploding tank hearth within the eyes of your enemies.
That stated, with the Metro Exodus staff aiming for 60fps at simply 1080p with all of its ray tracing tech turned on, there are nonetheless plenty of questions that have to be answered relating to how a lot of an impression ray-tracing could have on a recreation’s general efficiency.
Nvidia Turing RTX cool function #1: DLSS – what the heck is it and why is it essential?
Thankfully, Nvidia’s crammed a variety of different performance-boosting bits of AI tech inside their Turing RTX playing cards that may hopefully negate any potential ray-tracing impression if builders benefit from them. Certainly, for all the eye given to ray-tracing during the last month or so, it isn’t truly almost as fascinating as all the opposite bits and items Nvidia’s Turing structure provides as nicely.
Chief amongst them is DLSS, or Deep Studying Tremendous Sampling. Nvidia teased this function again at Gamescom with this quite obscure however intriguing RTX 2080 vs a GTX 1080 efficiency graph, displaying that video games with DLSS enabled on an RTX 2080 will be capable of ship as much as double the velocity of a GTX 1080 at 4K. Now I can inform you the way it truly works.
DLSS is fairly neat. In essence, it’s an excellent environment friendly type of anti-aliasing (AA) and makes use of Turing’s AI and deep-learning-stuffed Tensor Cores to assist take a number of the pressure off the GPU. AA, in case you’re unfamiliar with the time period, is a way recreation makers use to make strains and edges seem clean and pure as an alternative of one million jagged pixels.
It’s notably essential when enjoying video games at 4K, as extra widespread AA methods, comparable to temporal anti-aliasing (TAA), can typically soften pictures a bit an excessive amount of (negating that pretty sharp feeling 4K ought to convey) in addition to get issues a bit improper when scenes are occurring at velocity. Whether or not you’ll discover any of this with out assistance from a freeze-frame digital camera system, in fact, is up for debate.
However! DLSS isn’t nearly making photographs look higher. It’s about making pictures look higher and booting the body price proper up as properly. By getting the AI to generate these tremendous excessive decision pictures as an alternative of the GPU, DLSS frees up the GPU to focus on what it does best – pushing out all these pretty frames at scrumptious speeds.
Very similar to ray-tracing, nevertheless, DLSS is a separate function that not solely wants developer implementation, however enter from Nvidia in addition to they’re those that want to coach their intelligent AI boffin machines on every particular person recreation within the first place to ensure they’re doing every thing correctly. From what I’ve seen to date, although, DLSS is spectacular stuff that makes a very good first impression. If there’s sufficient uptake from builders to help it, it might be a serious string to Turing’s bow and supply a considerable benefit over no matter AMD’s cooking up.
Nvidia Turing RTX cool function #2: Variable price shading
A little bit of a nerdy one this, so bear with me. I promise it’s cool. One other nifty little bit of AI tech, Turing’s variable fee shading can present one other efficiency increase by concentrating the element of a scene the place it’s wanted most (within the centre, say, the place you’re focusing most of your consideration), and decreasing the extent of element elsewhere, similar to issues on the periphery or easier bits of geometry within the foreground.
To provide an instance, think about a scene from Forza Horizon four. The automotive’s within the center, you’ve obtained that fantastic British countryside stretching out in entrance of you, fields whizzing by to your proper and left, and the remainder of the street trailing behind you.
Naturally, the automotive and horizon are the primary focus of your consideration, so these bits will probably be given probably the most element. The fields to the aspect are much less essential, so they could have half as a lot shading given to them. The street, in the meantime, is certainly not the place your consideration ought to be targeted on this high-octane racer, so which may obtain half as a lot element once more. The top result’s a scene that not solely seems good and sharp the place it counts, however delivers a better body price than if all the things was being rendered with the identical quantity of element.
For those who’re nervous that this may make video games look a bit inconsistent, worry not. One other instance Nvidia confirmed me was the submarine space from Wolfenstein II: The New Colossus. Right here, variable fee shading was getting used to intelligently assess which bits of the scene to shade correctly with no lack of general high quality.
Technically referred to as ‘content adaptive shading’, this was arguably probably the most spectacular demos I noticed throughout Nvidia’s whole presentation, and the distinction between having it on and off was virtually imperceptible. There was a obscure kind of rippling impact current once I was standing inventory nonetheless surveying the centre of the primary management room, nevertheless it utterly disappeared the second I began to maneuver. What’s extra, the body price leapt by 15-20fps once I had it turned on, which is fairly spectacular for nigh-on similar picture high quality.
Nvidia Turing RTX cool function #three: Nvidia Scanner’s one-click overclocking
I’ll maintain this temporary as a result of I do know I’ve been rabbiting on for some time now, however this new software program API ought to make it simpler than ever earlier than to get the best out of your new Turing graphics card with absolutely the minimal effort. It’s going to be routinely embedded into all of your typical third get together overclocking apps like EVGA’s Precision software program, and this one-click program will primarily run a mathematical check over the course of simply 20 minutes that goes via each efficiency curve and apply its outcomes mechanically with out you having to do something in any respect.
In case you’ve ever needed to get into overclocking however balk on the concept of spending hours fiddling round in your PC’s BIOS settings, this might be music to your ears.
And eventually, 32 phrases on RTX cool function #four: Ansel RTX
Ansel, however with much more ray-tracing than you’d get in common ray-tracing gameplay. That’s 32x shadow samples, 40x reflection samples, 12x ambient occlusion, and 10x refractions per pixel. As a result of Ansel. The top.
Nvidia Turing RTX costs and release date
So how a lot will these magic graphics playing cards value and when do they arrive out once more? Right here’s all the data you want in one other useful graph:
Till I can speak correct efficiency figures subsequent week, nevertheless, it’s troublesome to say whether or not the RTX 20-series shall be value all that cash. All of Turing’s AI know-how is undeniably spectacular, and it might spell big positive factors in efficiency that may go a great distance in justifying their equally large improve in worth in comparison with Nvidia’s earlier era of GTX playing cards.
Then once more, whereas Nvidia have confirmed that a number of the features described above are getting bundled into Microsoft’s DirectX protocol, thus making certain a higher probability of them turning into extra widespread going ahead, others like DLSS require a bit extra work, not least from Nvidia themselves. It is going to in fact be in Nvidia’s best pursuits to get as many video games supporting their tech as potential, however for me there are nonetheless too many ‘ifs’ and ‘whens’ proper now to even start making a assured shopping for choice.
It’s additionally value making an allowance for that each one of those playing cards are actually solely being focused at those that play video games in 4K. Of the figures Nvidia has talked about to date, all have them have been for 4K, so it’s greater than possible that that is the place we’ll see the most important leap in general efficiency. Should you’re solely enjoying video games at 1920×1080 or 2560×1440, upgrading to an RTX card will in all probability be full overkill for you.
Certainly, the RTX 2080Ti has been described to me as a card that’s solely value shelling out for when you’ve got a 4K monitor with a 144Hz refresh fee. Simply let that sink in for a second. 4K. 144Hz. Most individuals gained’t want something close to that highly effective, so until you’re interested by upgrading your complete PC system to help 4K, these playing cards might be not for you in the meanwhile.
Subsequent week, nevertheless, all shall be revealed. Keep tuned.
