Nvidia wants you to spend about the same as an entirely new computer on its latest top-of-the-line graphics card, the GTX 2080 Ti. You could get a great laptop or a very solid desktop for the same £1,100 price Nvidia’s new card commands. You could get a couple of PS4 Pros or Xbox Ones! You could get an iPhone X or a Samsung Note 9. Point is you could spend your £1,100 on a lot of different gadgets that do more than a graphics card—so how on earth can it be worth it?
Nvidia’s last generation, the 10-series, came out about two years ago and is still available today, and its still plenty fast for most games. I say games and not things because unless you’re mining crypto you’re probably only in the market for an expensive graphics card so you can play games on your expensive computer. You don’t really need a pricey GPU for working in Photoshop or editing a film. GPUs are good at one thing—rendering 3D graphics, and most of us only need to render 3D graphics when we’re playing games.
But the point is the GTX 1080 Ti and 1080 are really solid GPUs that are comparable to AMD’s Radeon RX Vega 64 and 56 respectively. and the 1080 Ti costs £650—about the same as the new 2080. So why spend £300 more (that’s the cost of a new cheap iPad!) on the 2080 Ti?
After putting the £1,100 2080 Ti and £750 2080 through our standard battery of tests, and playing a lot of games on both a big 4K TV and a smaller 1440p monitor I...I don’t think it’s actually worth it—for now. The 2080 Ti is an exceptional piece of hardware, and it is undoubtedly the future of GPUs, but it’s so bleeding edge you can’t even do the coolest stuff it’s capable of yet on your computer.
The 2080 Ti, and its slightly less powerful sibling, the 2080, are Nvidia’s first consumer intended graphics cards based on its new Turing architecture. The secret sauce of the Turing architecture is a lot more power to devote to artificial intelligence.
No, this GPU isn’t going to be powering Hal 9000 or any other murder bot. Instead, the AI is used, in these cards intended for consumers at least, to better predict the behaviour of in-game elements. Specifically, the Turing architecture allows for Nvidia’s newest GPUs to perform ray tracing in real time—the “Holy Grail” for gaming GPUs. If you don’t know what that is that’s okay—outside of special effects houses and GPU enthusiast forums, ray tracing isn’t a commonly known thing. But it is very cool. Ray tracing is a kind of rendering in which each individual virtual ray of light in a computer-generated environment is traced from its source to objects it can reflect on. But ray tracing also means those rays can be blocked by a figure who moves in front of them, or distorted as they pass through translucent objects. This means objects in a computer-generated environment—like a video game—will reflect light more as they would in the natural world.
Today, when flame flickers in a game it might sort of bounce off the surfaces around it, but not realistically. You wouldn’t see the pinpoint of light from the flame flicker in the eyes of a character, or on the surface of a nearby window. To do that requires a whole lot of power that GPUs before Nvidia’s new 20-series were incapable of doing in real time.

Unfortunately, Nvidia’s 20-series of GPUs is incapable of ray tracing for at least another month. While the chips might have the power to do it (more on that in a moment) they don’t have the software support from Windows 10. Ray tracing in Windows 10 requires DirectX Ray Tracing and Windows ML, which won’t arrive until the anticipated Windows 10 October 2018 Update next month. So for the next couple of weeks these big beastly GPUs can’t do the task they’re designed for, and even after the update, there will only be a handful of games available that support ray tracing. Nvidia has noted only 11 supported so far, though it says more are coming.
Instead, the 2080 and 2080 Ti are just wickedly powerful GPUs that will make your current games run a lot faster. Especially in 4K. 4K itself is kind of bleeding edge too—at least when it comes to gaming. Until Turing, GPUs really struggled to render top games in 4K at a frame rate higher than 30 frames per second. 30fps is acceptable (that’s about the frame rate of movies and TV shows), but gamers prefer higher frame rates because a lot can happen in the span of a frame or two. 30fps is fine for casual gamers, but people who like intense shooters or fighting games are going to want at least 60fps, with 120 or 144 being coveted as well. (Note: We didn’t have 1080 Ti on hand, but the benchmarks below give you a sense for just how powerful the new cards are compared to the old 10 series.)
Nvidia’s last major line of GPUs, the 10-series, just couldn’t cut it, but as evidenced in the benchmarks above, the 20-series has zero problem pulling 60-plus frames per second in new video games like Far Cry 5 or Shadow of the Tomb Raider. It also does just fine in older games like Rise of the Tomb Raider, and it handily gives you more frames than you’d know what to do with in less demanding games live Civilization VI and Overwatch.
But I don’t know if I can actually recommend the 2080 or the 2080 Ti right now. Especially for their prices. Sure no machine, not even a dedicated 4K console like the PS4 Pro or Xbox One X, can match the 2080 and 2080 Ti for performance. This thing smokes its predecessors and the devices available from AMD at the moment. The 2080 Ti is fast and impressive, it’s just not £1,000 impressive. The 2080, which starts at around £730, is more impressive from a price to performance ratio, and if you’re upgrading a PC with a newer GPU inside, then it’s not hugely more costly than the much slower £450 AMD Radeon RX Vega 64 or a £350 PS4 Pro.
But it couldn’t hurt to wait, and I’d be bad at my job if I didn’t say that this review isn’t quite complete yet, and won’t be until ray tracing support is added to Windows and we can see how each GPU actually handles the effect. While the 2080 and 2080 Ti might be incredibly powerful GPUs they’re not quite worth it...yet.
- Nvidia’s new 20-series GPUs, based on the Turing architecture, are damn fast.
- They’re also hot (like warm), and the 2080 Ti costs £300 more than both the 2080 and the 1080 Ti.
- While the speed is impressive, the most impressive feature, ray tracing, won’t be available in games until October and will only be available in some games.
- Unless you need the speed right now wait a few weeks until the ray casting is available and we see how it does, or does not, affect performance.
