Question Speculation: RDNA3 + CDNA2 Architectures Thread

[uzzi38]

Man I have been dying to make this one for a while now.

First rumours for RDNA3 are here so new thread time!

Just going to start off with this one for now: kopite7kimi on Twitter: "@VideoCardz Ah, I mean a simple mcm design with 10240 cores is not enough. Because the lift from RDNA2 to RDNA3 is much bigger than from RDNA1 to RDNA2. We should expect many big improvements in GFX11. 🤔" / Twitter

Either way, the 7700XT is within the same ballpark as the 4070 but at ~80% of the price.

But 7800xt is only $50 more. A no brainer IMHO, at least at launch. Waiting 2-3 month probably means the 7700xt drops another $50. then it makes more sense.

I'm still however waiting for local (EU) prices to make a judgement. Heard it will be €550 and if AIB cards are more then it's more expensive than 4070 in terms of price (cheapest 4070 right now here is €520! but normal price also around $550)

Oops, I meant the 7800XT. But yeah, it's a better buy over the 7700XT.

Yeah those averages for RT are pretty useless, not only because CP is makes up half them but also because they're so heavily affected by the single RT Overdrive measurement where NV gets 3x the FPS but both are completely unplayable. Take out the RT Overdrive number and it goes from -11.6% average to -3.9% average.

 

[blckgrffn]

So it has something like the RT performance of the 3070 but with the framebuffer to actually back it up?

For a relatively "check the box" feature it seems like a reasonable performance level to me. Not sure what the expectation levels are, TBH. I know its important to some but really that seems like enough performance to be "playable" and observe the aesthetic. You want it turned 11 you already know you need to pay more.

Gives a decent idea of what to expect on RDNA4 as well. Which is to say put RT at the same level as raster and then add a good 10-15%, so looking at a 4070ti+ level of performance for the equivalent part, most likely.

If it's released for the same price a year from now that that'll probably be a really good deal, even if it's likely to be 12gb thanks to GDDR7. But also shows why they might want to skip a high end part and try to get GFX5 out ASAP. A 4090+ for $1k might sound good for all of a handful of months before Nvidia's new cards drop.

RDNA3 looks to have okay-ish RT performance, but AMD really does still need to improve there since they are behind NVIDIA. Power consumption/perf/watt is terrible, however.

- 6nm N23 confirmed? AMD absolutely has a dumptruck sized hole in their line-up between N32 and N33 and I have to assume that they knew that hole would be there even if RDNA 3 "lived up to expectations".

I wonder if AMD can bring the price of Navi 32 200 mm2 N5 die down to 300-399 price range. I doubt it, especially cutting large number of CUs to get to the expected performance range. Which would seem uneconomical.

A part where an entire shader engine is cut would be 40CUs and allow a different bin to just cutting CUs from working SEs. Depends on how many they have in that category though.

Can't imagine they would do that at this point. A straight rebrand would work though.

i think it can be AIB's exclusive like 6700 10GB. Big hole between 270 and 450$ maybe show RDNA4 summer 2024?

If the 7700XT slowly slip from 450 to 400-420 there wont be any hole left, that could be the plan on a few months term, and that would cost less than releasing a new card.

Other than this some FSR3 news with a short video :

Upscalers and perspectives: In offence of AMD's FSR 2.0

Image upscaling techniques in games have been a huge step forward, enhancing graphics quality while optimising performance. While the promise of better-than-native-resolution image quality is only a reality in a few select cases - usually because of poor temporal antialiasing (TAA) in the base...

[Frenetic Pony]

The expected tradeoff of image quality for smooth framerates is right there, for all that it looks good enough.

What I found from the register definition:

- only 1 SE
- IB1 stuff (a new instruction buffer format?)
- GC_ATC_L2
- some new VRS stuff
- some binning stuff

Not much else for now.

This is rather unexpected move by AMD, they rather launch the high power mobile N31 GPU than N32.....

Hmm, @TESKATLIPOKA, now are you convince that AMD going to skip mobile N32 and launch mobile N43 and N44 instead???

I don't think it's that surprising. N32 is probably selling a lot better than anything else they have given that it's already good value per dollar and becomes even more valuable with the bundled game if you wanted Starfield.

They've had plenty of time to stockpile N31 dies and they needed to do something with the dies that couldn't even make the 7900 GRE bin. Or that was enough of a flop that just getting it further to get 72 CUs that can still hit target frequency at lower voltages for a mobile part is a better use of the dies.

Until we have the frequency and power numbers as well it's hard to really evaluate the part, but they probably don't have enough N32 dies to release anything based around that at this point.

 

[jpiniero]

If N32 was in demand from mobile OEMs, it would have been released a long time ago.

Perhaps AMD offered a good enough deal on garbage tier N31 to get a deal or two done.

What are you talking about? Why should I be convinced that AMD will skip mobile N32?
We don't even know when RDNA4 will be released and with what specs, but you already assume they will skip N32 in favour of N43(N44).

 

[TESKATLIPOKA]

And N32 wouldn't be in demand in mobile because?
Didn't you notice It was just released in desktop?
But according to you, It was not released because there was no demand.

72CU N31 with 16GB Vram doesn't look that bad, but the question is at 175W what would be the clockspeed. If It can manage 2GHz then you have ~RX 7800XT level of performance. Could be very close to RTX 4080 laptop in raster performance.

 

[jpiniero]

OEMs do OEM things. Seems like for N33 laptop, all AMD got was that one TUF model and a random Dell gaming laptop that also has Ada options.

 

[GodisanAtheist]

It is weird that AMD is cutting N31 so heavily for their mobile part. No way there are too many "naturally" occuring 72cu parts.

Why not just release the 96/80 cu chips and just down clock a bit more to conserve power?

Certainly there are benefits to keeping the design wider and slower while still using "standard" parts?

Unless we're going to see an XT and XTX variant of the mobile part, but I don't think AMD has nearly enough presence in the laptop space to support that many skus.

 

[TESKATLIPOKA]

So there is a little demand even for N33, which is barely better than N23 and even on older process.
Yet according to you, there is no demand for 5nm N32, otherwise It would be already out.
Unlike N33, N32 has more Vram and is a lot faster than N22, so there is no reason why It should be in less demand than N33.

That has to be part of it. Say they don't have that many chips, but enough that they had to do something with them.
