The standings don't change much with our 4K ultra test results, though AMD does close the gap with the RTX 4070 Ti just a touch. Overall, Sapphire ends up 3.4% slower than the RTX 4070 Ti, with a slightly larger lead in rasterization performance and a slightly worse loss in DXR performance. Specifically, it's 10.6% faster in our rasterization suite, and 21.2% slower in the DXR suite.

If you ever want a good reason for upscaling algorithms, 4K gaming will suffice. Not only can  you get quite good results when doing a modest 2x upscaling (e.g. going from 2715x1527 to 3840x2160). That's because the more data you have, the 'easier' it is for AI and conventional algorithms to fill in the gaps.

Put another way, let's look at the extreme. Imagine a 2x upscale from 5x5 pixels to 7x7 pixels. The algorithm would need to interpolate from 25 total pixels to 49 total pixels, but there's simply not as much detail to start with. Conversely, when the target ends up being 8.3 million pixels interpolated from 4.1 pixels, there's a wealth of information available.

From a performance perspective, upscaling to hit 4K also has some great benefits. We explained why 4K requires so much more VRAM than 1440p or 1080p, and while games can do things in various ways, the end result is that rendering at 2K and then upscaling to 4K can result in some excellent performance gains with a relatively minimal loss in image fidelity. You're also not likely to be CPU limited when targeting 4K, which isn't always the case with upscaling to 1080p.

Native 4K performance in our rasterization suite ranges from 48.9 fps in A Plague Tale: Requiem to 107.1 fps in Far Cry 6. Only two of the games failed to average 60 fps or more (though Flight Simulator barely got there). But with the Sapphire RX 7900 XT, or the RTX 4070 Ti, every rasterization game is very much playable, particularly if you drop from ultra to high settings.

For our DXR suite, things aren't quite so nice. Only Spider-Man: Miles Morales and Metro Exodus Enhanced can even break 30 fps at native 4K, and Control nearly gets there with 29.5 fps. But the other three games are in the high teens or low 20s. Even with FSR2 upscaling, which only three of the six games support, getting to 60 fps might be a stretch.

You could of course use a different suite of games for testing to make the results look better, or use lower settings (particularly in the DXR games) to close the gap between AMD and Nvidia GPUs. Or you could enable upscaling where supported, in which case DLSS remains more widely used than FSR2. But ultimately, the RX 7900 XT and RTX 4070 Ti do deliver relatively similar overall experiences, even though AMD's card has 20GB while Nvidia's GPU only has 12GB of VRAM.

    If they get the 7900XT down to $699 I might consider getting one.

    I have to agree only the Highend options from both NV and AMD this gen are worth it. Anything below 4080,4090 and 7900XT,7900XTX just looks like trash.

    Or you can just recognize that HD texture packs often do very little for image fidelity and stick with settings that won't exceed 12GB (unless a game is poorly coded, which unfortunately seems to be the case with a lot of recent ports).

    With that attitude you don't need to buy a higher end GPU, just buy a console for much less than $600!

    This is actually a fair take. We're not talking about pennies here. These cards are mega expensive and saying "just compromise" feels wrong to say.

    I mean, people that buys a Ferrari Enzo won't use it* to haul big cargo or for off-road, but the cards above $300 start nudging the "if you need to compromise, just get a console" lever to me.

    As for the rest of the review, thanks for it. This card is a tad underrated as "cheap non-reference" cards go. The XTX version of this is same price as reference and a tad better (both come with the 3 8pin so you can OC it IIRC), so you can give them a good run for the money if you want. Also, they're better for Water Cooling enthusiasts as they keep the 3 8pin and aren't as expensive as the higher end cooled ones.

    Everything else is: "this is a 7900XT", haha.

    I wish you could give VR games a quick try and comparison, since friends with these are crying when I tell them my 6900XT is performing better at lower power than theirs.

    Regards.

    That's what I was going for. Mainstream and entry level cards have compromises, high end designated cards should only have ray tracing as their compromise (and that's not much of one in many cases).

    I also don't agree with TH's testing methodology here of requiring the use of ray tracing, since that is one area that usually brings a significant performance detriment for very little actual visual gain. In my opinion ray tracing shouldn't even be counted as a detail for the purposes of defining "max details", but a processing enhancement effect. Techpowerup's review did not use ray tracing for their average FPS chart (it's in a separate chart). They used 25 games, and some were not included from TH's choices, but it provides a far better real-world result. I hope TH will adopt a policy that will require all GPU tests to be run without RT, and if RT is to be included it should be placed in a separate chart, at least until such time when RT does not carry any more than a 10% reduction in performance.

    If we're going down that road, we shouldn't even test at ultra settings, we should just run everything at medium or high. And for those games that actually have ultra settings that actually do look better? Those are just "processing enhancement effects." We should also just test at 1080p, because 1440p and 4K are "resolution enhancement effects." Or put more bluntly, discounting a chunk of what modern GPUs can do just because you don't like how it impacts GPU rankings isn't something I condone or intend to do.

    You'll note in the articles where I look at new games, the conclusion is often (though not always) that ultra and high are basically equivalent quality but ultra requires more GPU resources for minimal gains. Ray tracing, at least in some games, actually does way more than the minor differences between high and ultra. Weakly/poorly done RT of course doesn't do much. So games like Far Cry 6, World of Warcraft, Shadow of the Tomb Raider, Dirt 5, etc. But when it's actually used more extensively, it can make a bigger difference, like Minecraft, Cyberpunk 2077, and a few other games.

    If you're willing to discount ray tracing hardware entirely, you can discount a lot of other stuff as well and end up with consoles. But if you're willing to compromise on ray tracing just because it's an area where AMD GPUs in particular perform much worse than their Nvidia counterparts, that's just intentionally limiting your view of a graphics card to favor one brand.

    Whats better the 6950xt for $600 or the 7900xt on-sale?

    People have different opinions about visuals but these cards are usually within margin of error of reference models, this test shows it as well. Im sure they can make just a rasterization chart for you personally if you are interested in this model but again I bet its within margin of error of reference model and you can always check that here: https://www.tomshardware.com/reviews/gpu-hierarchy,4388.html
    Its standard these days to separate those measurements. In this article I dont see 1080p and I am okay with that, its high end GPU and if its good at 1440p then I dont really need another page or two (which takes maybe even an hour or two to write) for 1080p because it wont say much.

    I agree, is there any online chart comparing same games´performance of all modern GPUs and consoles? I know digital foundry is doing comparisons like PS5 vs Series X vs high end PC but mixing consoles´FPS into these GPU charts would be interesting.

    I get your point but its not the best example, resolutions are standardized and its common for GPUs to behave differently, their power curve is often non-linear across resolutions...anyway RT should stay thats for sure.
