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

How AMD is this oblivious to where the market thinks their cards should be priced is beyond me.

AMD pretty clearly does not want to go below $269 on the 7600, and since the XT obviously costs more due to the extra ram and the costs of doing clamshell...

Now retailers might eat some of their gross margin to move product so possibly you might get slightly less at some point but unless AMD is willing to cut the margins even further... this is going to be the price.

If they can currently sell a 6600 for $200 they can sell a 7600 for around $200. There is no compelling reason to think the 7600 would have less margin than the 6600 at $200. The extra 8 GB and using a clamshell design allows them to price the 7600XT for $60 more than the 7600. Again, if they can sell a 6600 for $200 they can sell a 16 GB 7600XT for around $250 and maintain a healthy margin. The margin argument is the same one many participants in this thread made for why they couldn't sell full N32 for $500. You even insisted they must have canceled it because it wouldn't make enough margin to undercut the 4070 and still be worth producing.

They can, but they won't, as it doesn't make sense to take less or same margin on a newer product. When 8000 series releases, you'll probably see 7600 at 200, but until then idk

I agree that they don't have any real reason to drop it that low until the 6000 cards are out of stock but i have a hard time imagining these will be much more than $200 by the end of the year. You could be correct though. Is anybody really buying 7600's for $270 in a market where a 4060 costs $300? That isn't going to cut it when 6000 supply dries up. They need to do a price cut on the whole lineup now that Nvidia's done their refresh and lowered prices on their lower end offerings IMO.

I hope for AMD's sake that they didn't make too many of these chips, although the rumor is that the 7600 XT was only introduced because no one is putting those chips in laptops. So then the entire supply needs to be sold as desktop cards and they probably have too many.

 

[igor_kavinski]

Guess the AMD Advantage program is a failure.

Oh AMD...

 

[Aapje]

The rumor is also that Intel scrubbed the mobile Battlemage from their slides, probably also because no company is willing to gamble on not selling $2k laptops due to the GPU.

I think that both AMD and Intel need to improve their image among consumers with desktop cards first before laptop makers are willing to take serious volumes of their GPUs.

AMD actually sold better in laptops with RDNA2.

Or they should team up and make a compact dockable mobile GPU form factor that plugs to the underside of almost any laptop. If the price is right, there are gamers out there who wouldn't mind having that kind of freedom (not being limited to the built-in dGPU and being able to carry different vendor GPUs with them on trips). The external GPU enclosures are just too bulky.

Reminds me of this video:

Btw Framework 16 currently is available for preorder with Ryzen 7840HS/7940HS and the dockable GPU expansion with Radeon RX 7700S:

Choose Framework Laptop 16 DIY Edition (AMD Ryzen™ 7040 Series)

The Framework Laptop 16 is a high-performance laptop with an upgradeable and completely modular design that allows endless options for configuration, including a fully reconfigurable input deck and modular discrete graphics.

Laptops designs are not standardized and in many situations the effect would be to cut off some cooling to the laptop.

But it would be an interesting idea to sell an eGPU with a GPU designed specifically for that eGPU. It could be more compact and cheaper.

I saw that too but also heard that it's just MXM being dumped, they'll still sell soldered mobile GPUs.

Zotac (I believe) tried to use MXM GPUs for eGPU's but Nvidia nixxed that pretty quickly. If only Nvidia, AMD & the OEM's could have settled on a standard MXM layout, maybe the form factor could have really kicked off.

Nvidia's anticompetitive behavior does open the door to Intel to at the very least give AIBs a lot more leeway, so AIBs can use Intel chips to go after markets that Nvidia doesn't want to service.

Why RX 6600 are still being made and sold? I don't think there were a lot made after the mining crash (2022!), but I still see 6600 at $200 and 6650 at $240. N6 Navi 33 is smaller in die size (1.16x smaller), so it most likely costs the same as N7 Navi 23. I thought that 6600 supply would end sooner and it'll get replaced by 28 CU Navi 33 (7500 XT).

 

[Aapje]

The claim I've seen, which seems plausible, is that laptop sales to OEMs were way below expectations. So then they have to go to desktop.

 

[RnR_au]

I've had an RX 6600 for a year now in an egpu solution. 60hz fortnite on an 8th gen i7 with only 2 pcie 3.0 lanes.

Apparently this is still chip inventory from back then. AIBs might be assembling new boards from 2 year old chips.

nvidia has just launched a RTX 3050 6GB variant...

6600 already beats 3050 8GB by a big margin, the 6GB version is way below that (gtx 1660 level of perf). I don't think AMD wil respond to that card in any way.
edit: RX 6666 6GB edition coming soon /s

It was just to say they keep pushing old chips out too

at least with green team it makes more sense, as GA107 is a lot cheaper than the rest of their chips.

 

[igor_kavinski]

If AMD has old chips lying around, better to just start doing SLI on the board itself. They have released X2 cards before!

https://www.techpowerup.com/gpu-specs/radeon-hd-4870-x2.c236

They can up the ante by doing triple or quad SLI, with liquid cooling. Why not? What's the point of hugging those unused chips? Better to introduce crazy products that people will buy for the sheer novelty of it.

I'm sure they will eventually, but the 7600 is already really only single digits faster than a 6600XT/6650XT. If performance and production and sale prices are similar it's probably not a burning issue to get rid of the old stock and add in a new cut of N33.

Thanks AMD, for letting my 6800 XT purchase not go to waste.

Can't wait to see CUDA benchmarks on RDNA3!

-My understanding is that this project has been abandoned and as a result was taken open source.

The guy behind it was contracted by AMD, but as they got further along I think it was starting to get legally tenuous so AMD pulled the plug and the project went open source per the contract.

So I figure as CUDA gets new releases, new cards are released, and this project fallows, not much will come of this.

Cool nonetheless and a shame we don't have a proper unified direct compute language...
