AMD: RDNA 3 Speculation, Rumours and Discussion

5 major versions + minor revisions, not 4 (and even RDNA was in certain contexts marked as GCN, CDNA too)

 

They're all just flavours of GCN.
CDNA2 shader cores are FP64, but hey, still GCN all teh same.

 

This sounds inline with Intel's reasoning - you gotta put the major TDP contributor at the very top of "the cake". So you are able to provide effective cooling for those parts.

@GCN: As long as RDNA doesn't continue the trend of increasingly ineffective GCN furnaces it's all fine.

 

Eh, tags are still pretty toasty.
Which is kinda a challenge.
I wonder how they solved it.

That's Nvidia's job now.
AMD's aiming at phones of all things.

 

I was skeptical of the cache, and here it goes again - I wonder how much Joules the interconnect does consume and how AMD will handle the extremely high thermal density and low heat transfer rates of stacked silicon?

 

Not much.

By not using uBumps first and foremost.
Also pile of SRAM sitting under the actually hot logic isn't totally bonkers from thermal density POV.

 

The skepticism (I was one of them) was hardly undeserved. AMD were only doing a little better than treading water for far too long in the GPU space, and there have been far too many situations were AMD products were overhyped only to end up disappointing everyone. They've now earned themselves some slack in that regard as RDNA2 is very good.

It was an easy way for PC gamers to dunk on console owners. It wasn't the opinion of everybody (especially not here). Also bad implementations deserve to be criticized. DLSS 1.0 was deservedly torn to shreds, so what you're saying isn't 100% true.

 

Oh hell yeah it's all coming together.
Tune up in what, 36 hours?

Oh c'mon, AMD quoted very real numbers at their FAD and the likes of plebbit still went nuts with schizo theories of AMD somehow not having a GA102 comp part et all.

 

RDNA2 laptops, RX6600 and/or RDNA3 teaser?


To be honest, the one thing people want IMO is volume availability.
There's already plenty of news and reviews of cards we can't buy at MSRP.

 

Yes.

Yes (M).

Kiiiinda.
It's gonna be a fun show, and oh, our blue friends will be set on fire again.

Not until 2023 lol

 

Eh, they'll tease the refresh of RDNA2 more likely, and that vaguely. 6nm, much higher power and clocks, and hopefully higher memory speed (there's 20gbps GDDR6 memory controllers available).

They'll probably also talk about Van Gogh/laptops and whatever x3D is. Supposedly some specialized server chip with x3D is coming out this year so that makes sense. That being said, x3D might also be applicable to RDNA3. Either HBM or x3D seems preferable over a 512bit bus with 20gbps GDDR6 anyway.

 

No such thing.

No and no (even 18Gbps ICs don't exist in volume).

Oooh, it's amazing.
Really.

Hell tf yeah.

 

Van Gogh is probably dead:

 

The same Twitter account shared some Navi31/32 info.
One tweet from May 8th states: "Navi31 hasn't been taped out yet, and I don't think it will come out in 2022 H1."


I thought it was leaked that the Navi31 tape-out happened 2020?

 

He's just another run of the mill weibo tourist.

N31 is two parts you see.

 

Van Gogh is probably not dead, as evidence piles up on Valve using it in SteamPal.

It seems Panos Panay ditching the SoC was the cue for Valve going forward with their handheld console.

 

Alive and well, but hardly relevant at this point (premium FF part being relegated to handhelds is lol. Feels nvidia man).
Either way coup de grace in 15 hours.

 

no RDNA3 teaser ?

 

Flip the SRAM tile on itself, put two GPU compute tiles next to each other and you have your RDNA3.
SoIC powah!

 

He was speaking about the presentation of 3D stacked dies, which is what will be quite probably used for RDNA3.
