AMD RDNA5 Architecture Speculation

[LordEC911]

Intel B580 is almost like Intel's Ryzen moment in the GPU space. Right performance, right time, right price to shake things up. But will there be takers?

Is it? I don't really see it being sustainable on their current trajectory.
Good enough performance at a great price means a solid product but the timing is terrible.
If they would have launched it at any other point in 2024 it would have been amazing, especially towards the middle of the year, but at the end of Q4 within a month of competition?

Edit- To go back on topic about performance targets... I really think AMD's choice for RDNA4 is the sweetspot for average FPS gaming according to TPU.

N48(~7900XT) - ~180FPS @ 1080p native, ~120-140fps @ 1440p native, and ~60-80FPS @ 4k native.
That means with optimizing settings and/or using upscaling/FG you can make good use of those +$500 highend monitors, +240FPS @ 1080p, +200FPS @ 1440p, and +120fps at 4k.

N44(~RTX3070) - ~100FPS @ 1080p native and ~70FPS @ 1440p native.
Optimizing settings + upscalers/FG means good match for budget $200-$300 gaming monitors, ~200FPS @ 1080p and +120FPS @ 1440p.

Supposedly RDNA 5 will be a 3 chip lineup, and likely monolithic again. So I'd expect N48 and N44 sized die and another die maybe AD103 sized so they cover a slightly wider range than RDNA 4. Likely timeline is H2'26 most likely on N3P/N3X.

I think that UDNA/RDNA5 will not have a Halo Nvidia killer. Just 4k cards at max, and Nvidia will have a 8k max quality card with Rubin.

8K won't be a thing for many many years - if ever. Even on PC 8K seems excessive and on TVs it is borderline useless for anything smaller than 80".

I'm in accord with this, but i still think that Nvidia will not let the "Halo of the Halo" tier. AI rocks, but Nvidia is more competitive as ever.

My bet: UDNA will have 3 SKUs, one for FullHD, 1 for 1440p and one for 4K maximum settings.

Nah, it's still not useful for 80"+ TV's either at the distances people tend to sit from those.

And unless you're one of those freaks who is using a 40-50"+ TV on a desk from a couple feet away from you as a monitor, 5k is about the most anybody would need from a PC monitor as well.

The only real practical consumer use case for 8k displays would be VR.

Either way, GPU's aren't really designed for specific resolutions anyways. That's just a convenient categorization some people or marketers use to help push people in a certain direction. In reality, game demands vary heavily not just on the specific game, but also what kind of graphics options they offer, and obviously plenty of people prefer sacrificing some resolution for framerate and whatnot, too.

200-300% desktop scaling on 32-42" monitors could be nice. But you'd definitely want to play in 4K on these so this doesn't really apply to gaming.

UDNA rumor from Chiphell:
- N3E
- Q2 2026
- There will be a flagship

 

[DegustatoR]

- Q2 2026

I don't see that anywhere in the rumor though.

Yeah, that's not what the leaker mentioned this time. It's in the article.

The leaker says it may be N3P and also implies N3E may be oudated, especially as AMD will be likely having UDNA 1st gen against RTX 60/Rubin/Blackwell-Next. Also that it'll be chiplet based?

Yeah, that's not what the leaker mentioned this time. It's in the article.

Yeah, though I think AMD will try to launch UDNA especially the Halo Tier before Nvidia may launch a RTX 60 series in say October 2026. Ands AFAIK Q2 was the production date so UDNA launching Q3 maybe with Zen 6 as well makes sense. That brand synergy ala Zen 3 & RDNA 2 in November 2020 which was quite successful.

8K is perfect with integer scaling (pixel-perfect scaling).

1:1 = 8K UHD
2:1 = 4K UHD
3:1 = 1440p
4:1 = 1080p
6:1 = 720p
8:1 = 540p

I do "almost 8K" DSR in older games and it seems to make a difference. Native is 3840x1600 and 4xDSR is 7680x3200.

While true you're likely much better of using something like DLSS Ultra Performance instead.

I don'see 8K or even it's bigger ultrawide cousins being remotely "mainstream" anytime in the near future. Barring AI Reconstruction Sampling becames insanely good. Like maybe sometime in the mid 2030s PC Gaming kinda thing and for the console gen (if there's one) after PS6.
