While it was roughly 2 years from Maxwell 2 to Pascal, the journey to Turing has felt much longer despite a similar 2 year gap. There’s some truth to the feeling: looking at the past couple years, there’s been basically every other possible development in the GPU space except next-generation gaming video cards, like Intel’s planned return to discrete graphics, NVIDIA’s Volta, and cryptomining-specific cards. Finally, at Gamescom 2018, NVIDIA announced the GeForce RTX 20 series, built on TSMC’s 12nm “FFN” process and powered by the Turing GPU architecture. Launching today with full general availability is just the GeForce RTX 2080, as the GeForce RTX 2080 Ti was delayed a week to the 27th, while the GeForce RTX 2070 is due in October. So up for review today is the GeForce RTX 2080 Ti and GeForce RTX 2080.
But a standard new generation of gaming GPUs this is not. The “GeForce RTX” brand, ousting the long-lived “GeForce GTX” moniker in favor of their announced “RTX technology” for real time ray tracing, aptly underlines NVIDIA’s new vision for the video card future. Like we saw last Friday, Turing and the GeForce RTX 20 series are designed around a set of specialized low-level hardware features and an intertwined ecosystem of supporting software currently in development. The central goal is a long-held dream of computer graphics researchers and engineers alike – real time ray tracing – and NVIDIA is aiming to bring that to gamers with their new cards, and willing to break some traditions on the way.

As we discussed at the announcement, one of the major breaks is that NVIDIA is introducing GeForce RTX as the full upper tier stack with x80 Ti/x80/x70 stack, where it has previously tended towards the x80/x70 products first, and the x80 Ti as a mid-cycle refresh or competitive response. More intriguingly, each GeForce card has their own distinct GPU (TU102, TU104, and TU106), with direct Quadro and now Tesla variants of TU102 and TU104. While we covered the Turing architecture in the preceding article, the takeaway is that each chip is proportionally cut-down, including the specialized RT Cores and Tensor Cores; with clockspeeds roughly the same as Pascal, architectural changes and efficiency enhancements will be largely responsible for performance gains, along with the greater bandwidth of 14Gbps GDDR6.
And as far as we know, Turing technically did not trickle down from a bigger compute chip a la GP100, though at the architectural level it is strikingly similar to Volta/GV100. Die size brings more color to the story, because with TU106 at 454mm2, the smallest of the bunch is frankly humungous for a FinFET die nominally dedicated for a x70 GeForce product, and comparable in size to the 471mm2 GP102 inside the GTX 1080 Ti and Pascal Titans. Even excluding the cost and size of enabled RT Cores and Tensor Cores, a slab of FinFET silicon that large is unlikely to be packaged and priced like the popular $330 GTX 970 and still provide the margins NVIDIA is pursuing.
These observations are not so much to be pedantic, but more so to sketch out GeForce Turing’s positioning in relation to Pascal. Having separate GPUs for each model is the most expensive approach in terms of research and development, testing, validation, extra needed fab tooling/capacity – the list goes on. And it raises interesting questions on the matter of binning, yields, and salvage parts. Though NVIDIA certainly has the spare funds to go this route, there’s surely a better explanation than Turing being primarily designed for a premium-priced consumer product that cannot command the margins of professional parts. These all point to the known Turing GPUs as oriented for lower-volume, and NVIDIA’s financial quarterly reports indicate that GeForce product volume is a significant factor, not just ASP.
And on that note, the ‘reference’ Founders Edition models are no longer reference; the GeForce RTX 2080 Ti, 2080, and 2070 Founders Editions feature 90MHz factory overclocks and 10W higher TDP, and NVIDIA does not plan to productize a reference card themselves. But arguably the biggest change is the move from blower-style coolers with a radial fan to an open air cooler with dual axial fans. The switch in design improves cooling capacity and lowers noise, but with the drawback that the card can no longer guarantee that it can cool itself. Because the open air design re-circulates the hot air back into the chassis, it is ultimately up to the chassis to properly exhaust the heat. In contrast, a blower pushes all the hot air through the back of the card and directly out of the case, regardless of the chassis airflow or case fans.
All-in-all, NVIDIA is keeping the Founders Edition premium, which is now $200 over the baseline ‘reference.’ Though AIB partner cards are also launching today, in practice the Founders Edition pricing is effectively the retail price until the launch rush has subsided.
The GeForce RTX 20 Series Competition: The GeForce GTX 10 Series
In the end, the preceding GeForce GTX 10 series ended up occupying an odd spot in the competitive landscape. After its arrival in mid-2016, only the lower end of the stack had direct competition, due to AMD’s solely mainstream/entry Polaris-based Radeon RX 400 series. AMD’s RX 500 series refresh in April 2017 didn’t fundamentally change that, and it was only until August 2017 that the higher-end Pascal parts had direct competition with their generational equal in RX Vega. But by that time, the GTX 1080 Ti (not to mention the Pascal Titans) was unchallenged. And all the while, an Ethereum-led resurgence of mining cryptocurrency on video cards was wreaking havoc on GPU pricing and inventory, first on Polaris products, then general mainstream parts, and finally affecting any and all GPUs.
Not that NVIDIA sat on their laurels with Vega, releasing the GTX 1070 Ti anyhow. But what was constant was how the pricing models evolved with the Founders Editions schema, the $1200 Titan X (Pascal), and then $700 GTX 1080 Ti and $1200 Titan Xp. Even the $3000 Titan V maintained gaming cred despite diverging greatly from previous Titan cards as firmly on the professional side of prosumer, basically allowing the product to capture both prosumers and price-no-object enthusiasts. Ultimately, these instances coincided with the rampant cryptomining price inflation and was mostly subsumed by it.
So the higher end of gaming video cards has been Pascal competing with itself and moving up the price brackets. For Turing, the GTX 1080 Ti has become the closest competitor. RX Vega performance hasn’t fundamentally changed, and the fallout appears to have snuffed out any Vega 10 parts, as well as Vega 14nm+ (i.e. 12nm) refreshes. As a competitive response, AMD doesn’t have many cards up their sleeves except the ones already played – game bundles (such as the current “Raise the Game” promotion), FreeSync/FreeSync 2, other hardware (CPU, APU, motherboard) bundles. Other than that, there’s a DXR driver in the works and a machine learning 7nm Vega on the horizon, but not much else is known, such as mobile discrete Vega. For AMD graphics cards on shelves right now, RX Vega is still hampered by high prices and low inventory/selection, remnants of cryptomining.
For the GeForce RTX 2080 Ti and 2080, NVIDIA would like to sell you the RTX cards as your next upgrade regardless of what card you may have now, essentially because no other card can do what Turing’s features enable: real time raytracing effects ((and applied deep learning) in games. And because real time ray tracing offers graphical realism beyond what rasterization can muster, it’s not comparable to an older but still performant card. Unfortunately, none of those games have support for Turing’s features today, and may not for some time. Of course, NVIDIA maintains that the cards will provide expected top-tier performance in traditional gaming. Either way, while Founders Editions are fixed at their premium MSRP, custom cards are unsurprisingly listed at those same Founders Edition price points or higher.

Blame both. Why the f you blame AMD for NVIDIA's own fault?And yes, AMD had competitive offering on mid-end, not on high end. But, that's before 7mm. Let's see what will we got on 7mm. 7mm will be released next year anyway, it's not that far off.
PopinFRESH007 - Wednesday, September 19, 2018 - link
Yep, lets wait for those 7mm processes. Those chips should only be the size of my computer with a couple hundred thousand transistors.Holliday75 - Friday, September 21, 2018 - link
Haha I was about to question your statement until I paid more attention to the process size he mentioned.Fritzkier - Saturday, September 22, 2018 - link
We seriously needs an edit button. Thanks autocorrect.Yojimbo - Wednesday, September 19, 2018 - link
So you are saying that if AMD were competitive then NVIDIA could never have implemented such major innovations in games technology... So, competition is bad?dagnamit - Thursday, September 20, 2018 - link
Competition can stifle innovation when the market is involved in race to see how efficiently they can leverage current technology. The consumer GPU market has been about the core count/core efficiency race for a very long time.Because Nvidia has a commanding lead in that department, they are able to add in other technology without falling behind AMD. In fact, they’ve been given the opportunity to start an entirely new market with ray-tracing tech.
There are a great many more companies developing ray-tracing hardware than rasterization focused hardware at the current moment. With Nvidia throwing their hat in now, it could mean other companies start to bring hardware solutions to the fore that don’t have a Radeon badge. It won’t be Red v. Green anymore, and that’s very exciting.

Your Brave New World would involve someone else magically catching up with AMD and Nvidia's lead in conventional rasterization tech. Spoiler alert: nobody has in the past 2 decades and the best potential competition, Intel, isn't entering the fray until ~2020dagnamit - Sunday, September 23, 2018 - link
No. I’m saying that companies that specialize in ray-tracing technology may have an opportunity to get into the consumer discrete GPU market. They don’t need to catch up with anything.eva02langley - Thursday, September 20, 2018 - link
Not AMD fault if Nvidia is asking 1200$ US. Stop blaming AMD because you want to purchase Nvidia cards at better price, BLAME Nvidia!It is not AMD who force Ray Tracing on us. It is not AMD who want to provide gamework tools to sabotage the competition and gamers at the same time. It is not AMD charging us the G-sync tax. It is not AMD that screw gamers for the wallet of investors.
It is all Nvidia fault! Stop defending them! There is no excuses.

I accept that nVidia's choices are their own and not the "fault" of any third party. On the other hand, nVidia is a business and their primary objective is to make money. Manufacturing GPUs with features and performance that customers find valuable is a tool to meet their objective. So while their decisions are their own responsibility, they are not unexpected. Competition from a third party with the same money making objective limits their ability to make money as they now have to provide at least the perception of more value to the customer. Previous generation hardware also limits their ability to make money as the relative increase in features and performance (and consequently value) are less than if the previous generation didn't exist. If the value isn't perceived to be high enough, customers won't upgrade from existing offerings. However, if nVidia simply stops offering previous generation hardware, new builds may still be a significant source of sales for those without an existing viable product.Long story short, since there is no viable competition from AMD or another third party to limit nVidia's prices, it falls to us as consumers to keep the prices in check through waiting or buying previous gen hardware. If, however, consumers in general decide these cards are worth the cost, then those who are discontent simply need to accept that they fit into a lower price category of the market than they previously did. It is unlikely that nVidia will bring prices back down without reason.
Note: I tend to believe that nVidia got a good idea of how much more the market was willing to pay for their product during the mining push. Though I don't like it (and won't pay for it), I can't really blame them for wanting the extra profits in their own coffers rather than letting it go to retailers.
