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

I imagine they will try $550.

They will tout its AI performance in stable diffusion to justify $600. And if they are totally mad, $650.

 

[SteinFG]

I imagine they will try $550.

It's like they never learn. Normal price for this would be 500. But for radeon, initial impression is worth sacrificing to milk early buyers extra 50 dollars.

 

[gdansk]

Even at $500 it will have a hard time selling.
Generally slower than RTX 4070
12GB -> 16GB isn't a significant upgrade presently
No magic ML features that gamers seem to care about
It's not Nvidia

If they try anything above that they're lunatics

 

[Ajay]

Less than 2600MHz as anticipated. Not fixed in anyway? As for the price it'll be $500.
DOA but at least it isn't totally dead.

Might as well be. Stocks of the RX 6950 XT finally going down (prices going up except for XFX which must have cornered the market on N21 GPU chips) - so that'll take some pressure off the RX 7800 XT. Bit of a LOL there.

 

[igor_kavinski]

If they try anything about that they're lunatics

They will go full lunatic. People in charge of pricing these days have rocks in their heads. Just like I see some supermarket chains price smoothies artificially high and then let them sit on the shelves unsold, day in and day out, just wasting good fruit instead of pricing it reasonably and letting people enjoy something nice.

 

[SteinFG]

And judging by the boost clock, it's not reaching 4070 levels of performance.
If they'll launch it at 550, it'll be like "Here's something slower than a 4070 for a bit less than a 4070, with less power efficiency".
Most will just get 4070 after looking at that.

 

[Saylick]

Meh, 6800XT performance for $550 is uninspiring.

 

[Tup3x]

It would be a nice card for 499 € (inc. VAT). Though, I have a feeling that it's going to be >=599 € depending on model. In that case, meh.

 

[insertcarehere]

So now it appears that what I said 2 months ago may be the most probable outcome..

Its now legitimately possible that a very cut down version of AD104 (RTX 4070), which itself is 300mm^2 on N5, would be a rough match for fully enabled N32, which takes a similar area (~330mm^2 between GCD/MCD), while being more efficient, better at RT, and dedicating more die area to HW (E. G tensor for DLSS) for other features. If that's not an indictment on RDNA3 then idk what is.

AMD's GPU team are really far behind NV's this generation....

- I feel like AMD could throw a 400mm2 GCD at this whole thing and have another Hawaii moment if they were so inclined...

It's funny to see all these "disappointments" ))
Not sure what people was expecting but this simple math still stands
7900XT * 60/84 * 1.07 clock premium

 

[beginner99]

€600 is way too much. a 4070 can be had for below €550. and 7900XT if you look for €760. even at €550 it would be a hard sell vs the 4070 as the vram is the only advanatge it would have. At $600 the 7900xt probably provides better performance/$.

 

[tajoh111]

The leaked card card does not deserve the 7800xt name. It's a 7700xt at best.

Where the 6700xt was close to Nvidia last gen high end, the RTX 2080 ti, this rebranded 7700XT will barely match a 6800xt or RTX 3080.

This is a bad 7700XT and an awful 7800xt. It makes the RTX 4070, 25% improvement over it's predecessor look good.

This could lose to the 6800XT at 4K scenarios, where the infinity cache gets saturated.

Remember the RDNA2's 6800xt came with 128mb of infinity cache vs this 7800xt's 64mb of cache.

 

[gdansk]

7900XT perf * 84 / 60 * clock bonus

That's 60/84.

It's funny to see all these "disappointments" ))

I was expecting an improvement over the 6800XT. I don't think that's too much to ask.
But the formula shows there won't be an improvement. So then I ask for a discount below 6800XT prices. But that won't happen as 6800XT has been under $500. Then I conclude it is disappointing. It isn't improving N21. They didn't fix RDNA3. It was only delayed because of inventory management.

With the long delay some people were hoping they might fix it a bit to get higher clocks. But it is still a puzzle why they waited this long,

Well, yeah but I doubt that they try to price it competitively. It really should be a 4xx € card but it's likely another disappointment.

 

[Timorous]

Unless the TDP is really low that is a very poor spec for a 7800XT.

Clocks are about 14% higher than the 6800 so performance will be a bit behind the 6800XT unless it exceeds the stated boost clocks which the 6800 does and the 7900XT does.

 

[coercitiv]

I'm a bit surprised it's called 7800XT, I was expecting 7900 LE (Lite Edition). /s

AFAIK the discussed price for 7900 GRE is $650, and combined with the MSRP of the 4070, they'll probably price the 7800XT at $550 and start discounting from there (on day two lol). They may even go with $569 because that's how AMD likes it in 2023.

Maybe wishful thinking on my part, but there is still a chance that it's just a place holder web page, and this could still end up being 7800, non XT.

It just seems so weird, that after the flak against the 7900 XT pricing, and the absolute roasting NVidia of 4060 Ti for lack of progress over 3060 Ti, that AMD would look at that and say: "Hold my beer" and deliver a 7800 XT that delivers even less progress than the 4060 Ti.

Would be par for the course for RTG, honestly. "Anything NVIDIA does, I can do better" /s

It could also be that this is a low end model. 7900XT/X listed clocks are all over the place.

I would wait for benchmarks before jumping to conclusions. It is entirely possible that N32 will have a different performance profile from N31.

Image of all the dies from Powercolor:

AMD RDNA3 GPU family has finally been pictured together - VideoCardz.com

AMD Navi 3X GPUs as presented by PowerColor Thanks to the leak from PowerColor, we can now take a look at the full Navi 3X lineup. The full disclosure of the RDNA3 desktop lineup was nearly complete, with only one GPU missing – the Navi 32. However, a recent leak from PowerColor confirmed that...

[eek2121]

It is curious to me that AMD is using a different die for the GRE. I wonder what the differences are?

 

[Heartbreaker]

Pin compatible package with N32. So it likely only has 256 bit data bus, while the bigger XT/XTX package has 384 bit data bus.

I stated before that RDNA3 is a lost gen that may as well not exist at all. It missed the publicly announced targets regarding performance and efficiency by so much that just keeping selling RDNA2 would barely make a difference over this superfluous gen (exceptions are support for AV1 and slightly higher RT performance... nothing big enough worth a whole new gen).

I really hope RTG took lessons from this all around disaster.
