Radeon RX 7800 XT and RX 7700 XT revealed, plus more details on FSR 3

By - | Views: 40,726

AMD just announced the Radeon RX 7800 XT and Radeon RX 7700 XT Graphics Cards, and they're giving out more details on FidelityFX Super Resolution 3 (FSR 3).

Of course availability is the big question. AMD said to expect them both on September 6th from partners including ASRock, ASUS, Biostar, Gigabyte, PowerColor, Sapphire, Vastarmor, XFX and Yeston. Plus they will be selecting them direct on the same date.

Here's the specs sheets AMD gave out:

As for FidelityFX Super Resolution 3 (FSR 3), AMD have a new blog post up with even more details. The first titles to get it will be Forspoken and Immortals of Aveum some time in "early fall". With other titles confirmed to be adding it later including Cyberpunk 2077, Space Marine 2, Frostpunk 2, Squad, Starship Troopers Extermination, Avatar Frontiers of Pandora, Alters, Crimson Desert, Like a Dragon Infinite Wealth and Black Myth Wukong.

The key addition in FSR3 is frame generation that AMD say "uses an enhanced version of AMD Fluid Motion Frames (AFMF) optical flow technology and temporal game data such as motion vectors to generate additional high-quality frames for a higher framerate in supported games, up to 2x2". Useful for games that you want to bump up to 4K with Ray Tracing.

One thing they've address is ensuring it doesn't impact the UI of a game, so they include "UI processing included as an integral part of our solution to minimize any impact frame generation may have on the in-game interface" and FSR3 also includes the latest version of their temporal upscaling that's integrated with the new frame generation.

Another addition in FSR 3 is a "Native AA" quality mode that allows you to use FSR 3 without applying any upscaling but still gives you the high-quality anti-aliasing and sharpening of FSR. It will come with a performance cost though, but might look better than what AA some games provide out of the box.

AMD has also committed to keeping it open source and will be added to the AMD FidelityFX SDK.

Quoting: Loftyfor some reason i can't get excited about those graphs. Sure new games on ultra high @4k with raytracing are going to be demanding. But i can't shake the feeling that an uber expensive brand new high TDP 7900XTX with TFLOPs to space and back should be able to run these current games around 60FPS without FSR3.

will FS3 be used to justify even more shitty optimisation of AAA titles ?


Honestly AAA gaming is pretty much dead to me right now, it's not the Size of the games, the lacklustre optimisation, the exorbitant pricing models on unfinished releases with DLC being used as a patch, or the not actually owning it, or even the DRM anti-cheat spyware.. let alone the way these companies treat their staff. It's actually because most (not all) of these games frankly suck.

That said, im really enjoying Indie / AA and retro games a heck of a lot more TBH and i dont need FS3 for that.

One thing would be the improved Anti Aliasing that FSR and DLSS brings, that is what makes some people claim that it makes games look better than native. Also if we play with the thought that FSR3 and DLSS3.5 produces an image that is as good or better than native then you can run games at the same FPS but with lower power draw and thus lower temps.

sounds promising for linux support? noting dlss 3 has no linux support

Quoting: MohandevirJust out of curiosity, what prevents Valve from upgrading Gamescope's integrated FSR with FSR2.2 or FSR3?

Requires extra data (vector/camera) which needs to be manually generated.

There is someone on patreon who is adding DLSS3 and FSR2 to games that previously didn't have such features. I can't be sure but I believe its handled via reshade, he even has frame gen working on games that didn't originally have support for it.

Point being, manual work is needed. You can't just toggle it on like FSR1 or similar methods which just use methods like TAA for upscaling.

These new AMD cards are NOT good upgrades for people using the 6700/6800 cards.
AMD has even made sure people understand these are for the 5000 series or below for upgrade. I see these as being almost like a 6700/6800 refresh, or a 1.5 upgrade in some sense since they are just barely faster and just more efficient cards.

But are they more efficient if they are barely faster than the 6 series ? I mean my 6700xt is 12gb 192bit just like the 7770xt, But the difference is that the 6700xt is 186w TDP and the 7700xt is 245w TDP, which is a sizeable increase if you live in a expensive energy climate or a hot climate to boot. Some people have argued you can undervolt a 7700xt to maybe 200W to make it more reasonable, but by that same Token i have my 6700xt undervolted and i barely see 145w for total draw. i can actually game without overly concerning myself over heat or energy costs. Given i game at 1440p@60 most of the time the entire system sits between 145-165w in typical gaming scenarios.

That said i agree with the fact that they might be a good replacement for the 5 series. Id personally try to find a cheap 6700xt/6800 series on a deal and undervolt it, should last a good few years.

I agree. I'm looking into building a new rig soon and I was looking for a recent game to benchmark the whole stuff. Turns out there's no interesting title for me that's less than 2-3 years old. I'd want to try Cyberpunk 2077 now that it's less bug-heavy but turns out it's still 60 bucks and with the upcoming extension being quite pricey as well, I guess it's a no-go for me.

They make sales for it periodically. Though I think $60 for such sized game is normal.

It's kind of funny they position 7800 XT as 1440p gaming card. I guess their baseline is 60 fps for this designation? Something like CP2077 runs at ~140 fps with 7900 XTX at 2560x1440, so I'd say it's a good 1440p card? 7800 XT wouldn't be enough.

I’ve got a 5700xt and most games run very well at 1440. Ray Tracing would be nice, but I think I will wait until the 8000 series for a proper upgrade, and hopefully better contained TPDs

I slapped a 7900XT in my system after pulling out my 3080 RTX. Instantly enjoyed having just normal desktop stuff run smoother. Randomly(not really) Wayland started working in Debian as well. So, if you're currently running an nvidia card, upgrading just for some bug fixes in software and smoother desktop usage, the upgrade is worth it! One problem I had with the upgrade though; the 7900XT was vastly larger than the 3080 RTX. Funny enough, the PCB was the same size, but the heat sink just hung off of it about 4 inches further. It came with a bracket to stabilize it better... GPUs are just getting silly in size.

Congrats for switching to AMD.

I went for even bigger 7900 XTX and Sapphire Nitro+ model for it is especially huge. But the upside is that it's really silent and runs relatively cool even under heavy load. So massive heat sink is useful.
