Discussion RDNA4 + CDNA3 Architectures Thread

DisEnchantment · Mar 23, 2022

With the GFX940 patches in full swing since first week of March, it is looking like MI300 is not far in the distant future!
Usually AMD takes around 3Qs to get the support in LLVM and amdgpu. Lately, since RDNA2 the window they push to add support for new devices is much reduced to prevent leaks.
But looking at the flurry of code in LLVM, it is a lot of commits. Maybe because US Govt is starting to prepare the SW environment for El Capitan (Maybe to avoid slow bring up situation like Frontier for example)

See here for the GFX940 specific commits

History for llvm/lib/Target/AMDGPU - llvm/llvm-project

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. - History for llvm/lib/Target/AMDGPU - llvm/llvm-project

github.com

Or Phoronix

More AMD "GFX940" Enablement Work Landing In LLVM - Phoronix

www.phoronix.com

There is a lot more if you know whom to follow in LLVM review chains (before getting merged to github), but I am not going to link AMD employees.

I am starting to think MI300 will launch around the same time like Hopper probably only a couple of months later!
Although I believe Hopper had problems not having a host CPU capable of doing PCIe 5 in the very near future therefore it might have gotten pushed back a bit until SPR and Genoa arrives later in 2022.
If PVC slips again I believe MI300 could launch before it

This is nuts, MI100/200/300 cadence is impressive.

Question - Speculation: RDNA3 + CDNA2 Architectures Thread

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...

It depends.
Is it a NUC with a battery, screen, speakers and embedded gamepad?

Minisforum or other distributors may in time give us NUC equivalents with the full variety of AMD mobile parts.

I don't think AMD had things like this in mind originally, either:

MINISFORUM BD770i/BD790i

AMD Ryzen™ 7 7745HX, 8 Cores/16 Threads & AMD Radeon™ 610M 2×M.2 2280 PCIe5.0 SSD Slots PCIe 5.0 X16 connector ×1

store.minisforum.com

(mitx board with up to a Ryzen 9 7945 HX chip)

Or:

Minisforum UM690S

store.minisforum.com

A NUC form factor with 6900HX CPU & 680M graphics.

An actual SteamBox could exist in the future, perhaps

Nyo.
But it's portable enough.
Remember Devil's Canyon?

Perhaps it needs a rebrand after all this time.

No, that would just make things worse.

soresu said:
Just as with Athlon -> Phenom -> FX -> Ryzen.

I don't think this sequence ever made anyone think that Phenom/FX/Ryzen weren't AMD CPUs.
Frankly the problem is 100% marketing-side. Nvidia controls the GPU narrative to an obscene degree, that's the problem. Whatever AMD does, Nvidia will have enough marketing talent and shills and drones, I'm sorry redditors, to just sing whatever song makes AMD look bad and NV look good.

It needs to start with a marketing overhaul, not a rebrand. People don't hate Radeon for being called Radeon, they just see it as awful value because Nvidia is painting them so.

soresu said:
Radeon has a very long lineage at this point, which is both in its favor and against it.

You have the established name, but also all the baggage that comes with failed products, and times that the drivers were worse than just subpar on OGL and DX11.

I highly doubt anyone will care about RDNA 3 when it's gone. Except me, since I bought it.

You gotta astroturf your brand into existence. Worked for Ryzen, worked for geforce rtx™.

Geforce had the best marketers in tech.
Ryzen basically found Intel naked, hands tied to its back, laying drunk out flat on its belly in the middle of the street. All there was to do is sit and show that they had won.

Radeon needs a serious asskicking and even though moar CUs will do half the job, they don't know how to do the other half.

Honestly, imagine buying a Strix Point/Halo NUC.
You install some gaming loonix on it, then sit your butt at home and emulate any console since the dawn of time all the way to PS4 Pro, buy one of those and just...chill.

Tiny box behind the TV, you don't even notice it. Just complete Gamer Chill.
I don't even console game much anymore but that sounds like lazy night heaven.

Naah. Radeon is not the best performing product and competitor has the superior product. That's the problem for AMD. Some just want the best and the best is RTX 4090. It's just as simple as that.

Yeah, the turfing went from shilling efficiency, to NVENC, to DLSS, to now framegen or whatever.
Shills, whole lot of them, always on the message with NV tech marketing.

we had one whole NV gen where efficiency™ stopped mattering one bit, but then Ada went back on top and now it matters!

Or alternative interests.

I used to be mad into gaming as a kid, but these days I'm all played out and books, screen media and music are my jazz.

Remaining hardware interest is more curiosity and possible (but unrealistic) aspirations of putting my bachelors degree to use on 3D environment creation.

Lol which reminds me I need to cancel the Maya Indie license renewal before it cleans me out.

From what I can gather DLSS/framegen and denoising are always going to be a problem while RT remains a focus.

Software techniques like ReSTIR can only do so much to mitigate the problem of computational complexity involved.

Completely false, since when AMD does have the superior product in efficiency, cost effectiveness, raster, etc, it doesn't count.
Radeon can win 9/10 fights and NV will steer the discourse into that one bit they win.

That's the power of marketing and you do not even begin to understand how it works. The product is really only what people perceive it is.

Tup3x said:

It's not anything simple. You just don't notice any of the subtleties or how you're being manipulated by Nvidia.

I get it and mainly agree but there's definitely also a marketing impact. For example, the RTX 3050 is about 3.7x more popular than the RX 6600 (on Steam HW Survey) and the gap is growing wider. But one of those is cheaper, more power efficient, 30% better raster performance, and even has a frame gen.

If it was entirely rational product choice I'd expect less one-sided results than 78.7% choosing the RTX 3050. Maybe it's all DLSS but I'm pretty sure there's halo marketing from having the comically expensive RTX 3090 and 4090.

I think a lot of tech people overestimate how "rational" any product choice is.
Most people don't care 1/10th of what they should about hardware. They just want something that works well enough for their needs.

Marketing's job is to herd them towards the product that fits their needs. The PROBLEM is that Nvidia has no work to do in this regard, their rep is solid and their products are seen as the "default GPU brand you just buy". AMD has a lesser rep, NV has expertly kept alive the "Radeon drivers are full of bugs" reputation, and they don't have nearly as good a story to tell as to why or how their stuff would be better.

One thing I learned from marketing is that the product barely matters, it's how people perceive the product. NV has a nice story to tell, with raytracing and DLSS and Cyberpunk as a showcase. AMD is late in either of those and has...Starfield.
AMD needs to get a story quick, and that's something they've always absolutely failed to do. It's not even that hard, I can write one for them easily.

Aapje · May 14, 2024

Many people don't want to do an in-depth investigation into what product is better and don't know whose advice to trust anyway. They just want to slap their dollars on the counter and get a product that works. So they get the product from the most reputable brand.

Yeah, it's called mindshare. Nvidia wins by a landslide in that regard. Also, this AI boom has catapulted Nvidia to the top of everyone's mind.

AMD just need chose good game and make it RT adversitment for RX cards

AMD drivers are stable. What is unstable and buggy its AMD software.

Ehhh, that guy on Xitter tries to come off as being a neutral party, but I've seen enough of his posts to conclude he definitely has an Intel/Nvidia bias and is not to be taken seriously.
1) He's active in the WCCFTech comments (big yikes)
2) Has Nvidia's Lovelace marketing as a profile picture
3) When this whole Intel CPUs debacle blew up, he conveniently said that everyone was to blame... like really? The consumer is to blame here for putting so much value on benchmarks that Intel was forced let mobo manufacturers juice up the chips? GTFO of here with that nonsense!

It's cope, but expected assuming your claims of wccf poasting are correct.
