Discussion RDNA4 + CDNA3 Architectures Thread

[DisEnchantment]

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

Or Phoronix

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

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...

Boys get GT1030 for physx, men get their trusty THERMI from their sheds

 

[tsamolotoff]

At some point when you get unstable you will only notice with decreased performance

Not only that, there are also timing straps that might make something like 2124 (second last strap for vanilla 6900xt) more performant than 2150 even if there is no ECC performance hit. You can check that with vulkan membench, although it might not reflect the whole difference

@gaav87 and overclockers. Apparently these transistors can lick around 4 gigahurtz? I did not expect.

Yeah, I've seen people hit 3.7GHz in Minecraft, which is a bit silly. The issue is still the power limit though, but it seems you can shunt mod the card to bypass TBP limits now. TGP limit... less so.

The prices have increased by $100 and that's why retailers are stupid. People have no issue punching their grandmother in the throat and stealing her social security for GPU money. They could have jacked the prices up $300 across the board and they'd still get scalped for double that cost at least. Also, how can I make sure our resident autist extraordinaire knows I didn't mean any disrespect to him? If he's that smart then that makes him kind of scary, sort of in a Mr. Robot kind of way.

People arent willing to pay as much as you seem to think. Most scalpers listings are around $1000-1200 and aren't selling.

This ebay listing ended without hitting reserve at $180 over retailer pricing ($760)



Heck, newegg is selling cards in combos with a $120 power supply and they arent selling quickly at all. People aren't super willing to pay even $120 extra despite getting something for it they can use or resell to cover most of that additional cost.

 

[GodisanAtheist]

Wow, another plus for AMD. They're so undesirable that cannot even be scalped in this market!

0 mindshare doing the Lord's work right now

With AMD continuing to sell the "$600 MSRP" narrative, im not surprised people arent willing to pay that much extra.

Whatever few people were willing to pay scalper prices already did a long time ago. Now scalpers are just sitting on stock that won't sell and arent willing to drop prices.

 

[Mopetar]

I'd love to see AMD drop another huge pile of cards just so scalpers get stuck and the retailers can't unload their unwanted crap by bundling it.

AMD really only needs to keep the $600 cards in supply until they stop flying off shelves immediately. After that they can trickle them out more and let the AIB partners sell their custom models at whatever markup they want.

AMD have missed their chance and even misled eager upgraders who might have seriously considered 9070 cards but for robber baron AIBs..

I don't how much of an issue TSMC capacity reservation is for AMD if they knew they will have a competitive Radeon this time.
Their reference designs looked neat and they should have seriously come in with enough of those MbA cards along with Sapphire Pulse designs with steady supply. AIBs shouldn't have any wiggle room to go more than +10% for a 5% OC performance boost as typical OC cards. $600 ref, $660 OC for the XT would make it as popular as the 7800X3D/9800X3D.
I really wouldn't care if AIBs go out of business and we are left with OEM designs from AMD/Intel/NV. AIB thermals are of paltry value and they have to make $$ on volume.

But then, it could be very likely that AMD saw the opportunity to jebait reviewers and cash-in. Their thuggery in CPUs is like how Intel was making a fool of buyers in mid 2010s. Less said the better about Strix "AI PC" crap and Halo SKUs' pricing even for the base APUs.

How have they misled anyone? There were MANY MSRP cards available.
Again they cant supply all the missing Nvidia demand on a whim.
Yes they missed a chance, but one that was unpredictable.

The last statement there is just simple hogwash. There seems to be a huge double standard that people have with AMD.

Oh no a premium product costs MONEY.
How dare they not sell it for treefiddy.

People seem to be forgetting we're only 3 weeks out from the launch of the 5070 Ti. Demand for N48 has way outstripped supply, but even knowing that it's a good chip if AMD had come to launch with twice the number of cards it wouldn't be enough. On the other hand, if Nvidia hadn't fumbled launch and you could walk into any computer store and walk out with a $750 5070 Ti then how many people are going to be choosing a $600 9070 XT?

 

[adroc_thurston]

how many people are going to be choosing a $700 9070 XT?

It wouldn't be $700 since there's less demand in that case.

 

[jpiniero]

Only at launch because AMD gave out the rebate.

There isn't going to be much reason to do that again until nVidia decides to ship something.

Sorry, meant $600.

AMD publicly stated more MSRP cards are coming.

AMD would literally be giving money away (given the current state of the market) if that's the case.

Your posts are being reported. We don't allow flame bait in vendor threads. You want to trash and bash AMD do it in a rival vendor thread. I am deleting your other flamebait post, don't make any more.

Lol, PowerGPU posted this on their Xitter account: "AMD inventory vs. Nvidia inventory"

 

[Mopetar]

Well one way for AMD to gain market share is for Nvidia to not have any cards to sell. I doubt that it's the same everywhere, but at least at this one store AMD is going to claim 98+ % market share.

By sorting sold items on ebay, the number of 9070 XT's that sold between $1000-$1400 is enough to form a literal mountain (and no, that specific cube wasn't solid). Watching the GPU market the last few years and seeing gamers' buying behavior has really revealed the ugly truth. These are outrageously impulsive people (you guys, not me) who will pay hilarious sums of money to get their product. I think of behavioral science books and theories that describe animal behavior involving food and other reward-inducing stimuli, and the gamer is the perfect target for these strategies because their human-based delayed gratification functions are disabled when it comes to GPUs. The gamer is literally the same as a mouse that has the ability to use credit to receive their reward. No thought is given to the price or consequences at all. They will simply push the buttons needed to get their reward until something stops working. In this case, they run out of money without even realizing what they've done.

Can you link the page? Id appreciate it.
I need to see the train wreck!

Sorted by sold items and highest price first. If you scroll through many, you'll see how the sold price generally falls slowly as the release date gets farther away. The panicked gamer has done generational damage, yet again, with their absolutely insane, unhinged, lunatic buying behavior. By purchasing at these prices, the zombified, brain dead gamer has sent an enormous bat signal style message in the skies above to the world that they crave, love, and enjoy higher GPU prices now and in the future.
