AMD: RDNA 3 Speculation, Rumours and Discussion

Unlike 3090 being advertised for 8k, these cards will do 8k and 8k already has a couple of reasons in this video for back to the future.

 

Do they give any reason why they use vastly different scenes for 4k and 8k respectively? I didn't hear any commentary and while this might be ok-ish for 6900XT <-> RTX 3090 comparison [edit: strike that, different time of days in some games like AC:V or Hor0dawn and camera angles WDL], it certainly invalidates 4k -> 8k scaling.

 

8k has to be the most wasteful use of GPU cycles.

 

I used to think the same about 4K but the benefits become more apparent as the resolution of assets and effects increases in newer games. Native 4K is still a waste though given how good reconstruction techniques have become.

 

These cards won't be anywhere closer to being capable of doing 8K than 3090 is right now.
8K is years off, in both GPU processing capabilities and display devices.

I also kinda doubt that 8K will even become that widespread considering that you'd need >80" display to be able to see it from a typical TV viewing distance.

 

nah mate, notice how the matrix demo on series S at ~530p is visually far superior than eg halo infinite on series X @ 2140p, 16x the pixels yet it looks far worse. Quality > quantity

 

Well, Navi 31 is expected to be ~2.5× faster than RTX 3090 and AD102 should be about ~2.2 faster than RTX 3090. That's:

• 66-75 FPS in RDR2
• 68-78 FPS in Flight Simulator 2020
• 68-78 FPS in Assassin's Creed: Valhalla
• 79-90 FPS in Horizon Zero Dawn
• 128-145 FPS in Forza Horizon 4
• 110-125 FPS in Watch Dogs Legion
• 101-115 FPS in Fortnite

That's all solidly above 60 FPS i 8K, so not even FreeSync / G-Sync is needed to achieve good fluent result.

 

Not sure how that’s inconsistent with what I said. What about matrix at 530p vs matrix at 4K?

 

No. Crypto-mining is.

 

I feel singled out as I actually have an 8K monitor

 

This is exactly what I thought. The Matrix may look better overall but the image quality on XSS is horrendous and would absolutely benefit from a higher base resolution. In fact the more realistic the graphics, the more likely you are to be pulled out of the immersion by a noisy or aliased image so The Matrix would likely benefit more than most games from a higher resolution or higher quality reconstruction method with reasonable base res. That's notwithstanding my comments in the other thread on it benefiting from some kind of post processing filter to make the image look more TV like than CGI like.

 

That's a nice list of previous generation games without ray tracing being active.
Not sure how it is relevant to what people will actually want to run on their future GPUs though.

 

Like 3090 they will be for enthusiasts who use the latest and the greatest. No widespread adoption necessary for years or even a decade. Linus already did a 3090 8k review at launch last year with nvidia's blessings.

Techpowerup's latest reviews show the high-end cards( 6800XT and above ) doing close to 100fps overall at 4k. Both AMD and nvidia will have to market 8k in order to show relevant differences at that point. nvidia have already done it with 3090, AMD can't do it with 16GB only.

That games list isn't going to change that significantly in a year.

HZD will get an update, GTAVI isn't certainly going to be out and FH5 already runs at 50fps on a 3090.



Recent games have also significantly upped the VRAM requirements, many having issues with 3080's 10GB at 4k and Far Cry 6 flat out requiring 16GB with HD textures at 4k. Improved textures for 8k would push it even further.

AMD will be shooting themselves in the foot if they put out a card with 2.5x the horsepower of 6900XT and hobble it with just 16GB of VRAM.

 

There is nothing about Far Cry 6 that needs 16GB.

 

At least some of LG’s new OLEDs shipping Q2 of next year are 8K.

While I do agree with the point that next gen likely won’t have enough juice for 8K, it is important to note that 8K displays do exist, and games will look better in 8K.

 

With reconstruction techniques advancing as they are I doubt we will ever see a move to native 8k. I imagine today that an 8k output in DLSS performance mode (4k internal) would look pretty damn spectacular (wish someone would make this comparison). Probably very comparable and likely better in some aspects to native 8k. By the time native 8k screens are prolific, DLSS or potentially superior upscaling solutions will likely be able to beat out the native resolution in most regards.

 

6nm Navi24 to be released soon.

Looks like the 6nm Navi33 will be here miuch sooner than the high-end RDNA3 cards.

 

How so?
