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

This dude is about to put everyone to sleep!

I almost posted the same thing.

EDIT: High refresh 4k is here!

I really wish they'd just find someone with a little bit of energy and give them a hit off a crack or meth pipe before shoving them up on stage. Maybe it would be a train wreck, but damn if it wouldn't be captivating.

90k people watching the livestream on YouTube. Seems like a solid number?

Is there going to be a slide comparing 7900xtx vs. 4090 performance?

I'm guessing not.

No because it is generally worse. Radeon marketing team doesn't go that way.

 

[blckgrffn]

335W TBP? Only two 8 pin adapters?

 

[DiogoDX]

2.4x CUs x 1.5x RT perf/CU = Up to 3.6x RT performance?

96 CUs.

Welp, hopefully they are cheap.

Also, forget everything I said about AMD making the same mistake as "sweet spot" for not building a larger GCD and taking the crown. The huge architectural advantage that AMD had (and largely squandered) with RV770 is not the case here. A larger GCD might have matched raster but still would have lost terribly in RT.

 

[Saylick]

Day one purchase at that price for me.

 

[Glo.]

999$ MSRP.

WHAT THE ****?

 

[blckgrffn]

999$ MSRP.

WHAT THE ****?

Game on. Let's go.

"no new case, no new power adapter." hold for smirk and applause

And smashing on the DP version. haha. 4090, already outdated baby!

 

[gdansk]

4080 is dead then at $1200. And anyone who uses CUDA is better off saving up for a 4090.

Ummm that doesn't look very good... Especially RT.

vs. the 6950xt? at $999?

We expected a Zen moment, we got an almost Vega moment. At least power consumption and video features are OK, price seems "good".

 

[In2Photos]

So that 6950XT I just found at $800 isn't a good deal huh?

 

[Karnak]

4080 is dead then at $1200.

How? The 4080 will be a lot faster in RT. RDNA3 even struggles against Ampere if AMD's numbers are to believe...

If you want RT buy a 4090.
If you don't get a 7900.
Pretty sure that's the right path

It's not like the 7900 won't be able to run RT at all

And engines are going to keep optimizing for Radeon RT.

I am not disagreeing in general though, just if you think RT performance is the most important purchase factor for the next 18 months, then the 4090 is the choice to make.

But that's not good for the market and not good for AMD either to "ignore" RT. Which they do according to their own benchmarks.

This is def not as bad as the Vega disaster, but it's not good either. Still disappointing tbh.

Sigh. I'm beginning to dislike the new AMD (not that I'm fond of Nvidia as a business either). If they had been able to deliver a much larger increase in RT, then maybe. And while DP 2.1 is nice, Nvidia just offers more stuff (CUDA, Tensor stuff, etc.). 7900XTX should have been $700, maximum.

I did except more in Cyberpunk since it makes heavy use of ray tracing when all enabled.

 

[Saylick]

FSR 3 is REAL???

Ah crap, sounds like interpolation:
