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

That's more of an argument for cancelling N32 than it is doing a further cut N31.

Well, N32 exists, so it’s a matter of just not putting it into production, aside from whatever numbers of wafers have been made already (not many I’d think).

 

[Ajay]

I don't get what makes it preferred for the mobile?
Anyways, this could only solve part of the problem - cost, while the other part - not having enough N31 downbins - is yet to be solved.

Good point, when downclocked, even more dice would pass QA.

 

[Aapje]

The package size, because space is at a premium in laptops. And with motherboards made to fit exactly, a larger chip means a complete redesign, which is very expensive.

 

[insertcarehere]

So what about 7700/7700XT? Cancel that tier this gen?

If it doesn't make sense to service that performance tier at acceptable margins to AMD? Sure AMD would leave that segment open, they happily left the <200 desktop CPU market to Intel on similar rarionale.

The performance gap between N33 and N32 is likely to be so big that there's nothing there that can serve at N22-performance levels without neutering good dies more than AMD would like. If full N32 runs at/above 6800XT levels it's gonna take a lot of cutting to make a SKU that performs like a 6700XT.

They could use any N31 die, does not need to be the 70CU one. They would be limited to 16GB and 4 MCDs though but.

If full N32 runs at/above 6800XT levels it's gonna take a lot of cutting to make a SKU that performs like a 6700XT.

The 6800 is about 22% faster than the 6700XT at 1440p and the 6800XT is 41% faster at 1440p. The 7700XT should with a normal 30-40% gen on gen improvement land in that range somewhere.

So if 7800XT is the 70CU N31 and the 7800 is a higher clocked 60CU N32 then the 7700XT could be a 16GB 54CU part. Give it slower VRAM than the 78 series and underclock it a bit vs the 7800 and you have a perfectly good 2nd bin part that will give a great uplift in probably the most competitive part of the market. Price it around $450-500 and it will destroy the 4060Ti 16GB and probably be just on the heels of the 4070.

I think AMD marketing painted itself into a corner by calling the low bin N31 7900xt.
It's not clear why should the n32 desktop gpus be called 7800 at all, and not simply slap "7700/7700xt" on it and call it a day?
Actually, the gap between n32 and 31 is not as big as it might seem.
They just have to inform tech media and community that it's unlaunched and immediately launched again, only now it is 7800xt.
Dead easy ))

Because of what they wanted to charge for it.

And fact is that the 7900 XT price is still higher than the 6800 XT, so it does seem to work for them.

 

[PJVol]

Because of what they wanted to charge for it.

I can admit this intention had certain grounds, even if based on the performance stated in official pre-launch slides. What I disagree is that their appetite was not adjusted in accordance to the noticeably lower actual performance of the retail product.
Of course they can price it how they see fit, but as a result use their 7900xt's and 7600's as bricks to build a new office somewhere.

And fact is that the 7900 XT price is still higher than the 6800 XT, so it does seem to work for them.

How do you know it works? Is there any data on its expected and actual sales, at least for the last reported quater?

We know that they currently are sufficiently happy with the sales at this price point to not lower the prices to $649.

The Sapphire Pulse RX 7600 was available briefly for $243 from Amazon already too.
At $250 I think the reception would have been better. But still not a low enough price to change anything.

This price, $249 for 7600, is going to move mountains.

So, we were told by some posters couple of weeks ago...

 

[Ranulf]

Well, it might have been better weeks ago...now it is just proof it was overpriced and many will keep waiting for more price drops.

All of the reviews include the original price, and the 4060 review embargo is going to be lifted in a few days. AMD had a window to get in a better position, and they blew it.

 

[Mopetar]

Even $250 isn't all that great for what you get. AMD realized they had a window where they could charge $270 and decided to see who they could get to bite.

Call me when this hits $225 and that's where it should have started. No doubt it would have sold well if they did start it there, but they'll pocket an extra $50 for anyone not willing to wait a few months.

I'd like to think the market has smartened up a lot, but I suspect that too many people bought the previous generation at elevated prices or from scalpers and don't have fat enough wallets to justify an upgrade that's so paltry.

 

[GodisanAtheist]

I only hope the price keeps dropping and puts downward pressure on basically equivalent used 6600XT/6650Xts in the used market.

As soon as one of those hits $100 shipped I'm in for one to replace my aging 980Ti in my secondary machine.

You need to keep in mind that the market is not a single person, but a lot of individuals, each with their own situation and desires.

I think that they just ran out of people who are fine with no or very little price/performance improvement.

You can see why I've been saying that AMD should cancel N32.

 

[TESKATLIPOKA]

No, I don't see It. Why should they cancel It? Just because you said so is not a very convincing argument If you ask me.

N32 is not a bad GPU looking at the specs. You have enough Vram, good enough BW and even raster performance should be at RX 6800XT level or maybe a bit more.
What will not be great is RT performance, but still better than RDNA2.

So what's the problem? High price? If It doesn't sell well, then they will lower It like they did with RX 7600 or RX 7900XT.

It's not like you have a better alternative out there with Nvidia costing more and having lower amount of Vram, Intel being cheap but with high power consumption and low performance.

 

[Mopetar]

You can see why I've been saying that AMD should cancel N32.

I don't see why. They already spent money developing it and unless they legitimately can't manage to turn a profit on it (or selling discounted RDNA2 cards is somehow more profitable) then there's little reason not to eek out a small bit of profit instead of none at all.

If N32 doesn't make financial sense then N33 has to make even less for them. I suspect they can make good money selling N32 from $450 - $650 depending on the configuration. Full Navi 32 should stack up well enough against the 4070 that they can price it similarly.

 

[jpiniero]

If N32 doesn't make financial sense then N33 has to make even less for them.

I agree but they did get a couple laptop N33 deals. That doesn't entirely justify the 7600 but perhaps AMD overestimated the demand for N33 laptop and needed a place to dump the dies.
