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

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 is crazy with as much stock as was available thats a huge sellout.

 

[adroc_thurston]

I think the main reason AMD didn't try with the top die is because of the RT deficit against Nvidia

It wasn't a die at all and the reason is far simpler.

 

[GTracing]

An hour after launch, Newegg has one 9070 at $650 and one 9070 XT at $820. Everything else is sold out.

For comparison, there are a few 5070s at $700. All the 5080s and 5070 ti's are sold out.

And all sold now on the radeon front.

At newegg, yeah. Amazon still has a few models at comically high prices. Cheapest one is $760. Microcenter has boatloads of stock still.

Spoiler: Screenshots

 

[Glo.]

In Poland, in one of larger retailers 37 models, only 7 in stock already.

37 models of both 9070 XT and 9070. And those 7 in stock are ONLY 9070 GPUs.

 

[Timorous]

Managed to get ocuk to load.

They had pulse and reaper XT models at MSRP in stock.

The view counts are crazy though with over 8000 on the pulse and 4000 on the reaper. Issue is that the site keeps breaking due to the extreme demand.

 

[GodisanAtheist]

Man this timeline really does suck. Demand is way up and supply is way down basically all the time.

Well Nvidia tends to absorb demand spikes usually, but this time they're late to the party and so you have this.

 

[coercitiv]

Remember remember, this is what stock greater than all 5000 series shipments looks like. Poof in 2 hours.

 

[Timorous]

Those MSRP cards at OCUK have sold by the looks of the change to the html for the product link. They did say they would release the MSRP cards in batches throughout the day rather than in one go to give people a chance to get one.

 

[tsamolotoff]

Our local etailer wisely set the price at double the msrp, so tomorrow there will be plenty of stock >.<

 

[Mopetar]

Remember remember, this is what stock greater than all 5000 series shipments looks like. Poof in 2 hours.

Not exactly a high bar to clear. The picture someone posted earlier where there were tens of Blackwell cards available across the entire lineup vs. hundreds of Navi 48 cards is rather telling.

3080 Geforce

No sense in such sidegrade for 6800xt and upwards owners, especially if you consider that you can MPT n21

 

[Abwx]

Is this why AMD dumped a load into channel before fully cooked?! To make market share look better. Peddie tracks shipped from company, not shipped to end user.

They track shipped by a few OEMs in PCs sold by the same OEMs, the retail dGPU market is not accounted at all, that is, most of the DT dGPU market is not accounted.

 

[Avalon]

Used newegg, not sure if mistake.
Site kept erroring out when I had MSRP card in cart, then it went OOS.

Seems like I was able to order the PowerColor Hellhound Radeon RX 9070 for $630.

Ugh, same. Then I tried looking at other models and it was all $750+ for like Hellhounds and Pures. I'd pay $50-$60 for a mid tier model, but I'm not paying $150 more for one. Guess I'm stuck waiting.

 

[beginner99]

Could't catch up here but reporting from europe. Availability just as shitty as NV. Everything sold out in minutes.

Prices is a joke. Incl vat it is $850, and that with a very low vat of 8% not the usual 20%. So about $200 more costly than it should be. How are US prices?

In the end I will wait for more supply and lower prices. But this msrp bullshit needs to stop. If nv suddenly has supply, 9070 xt will again fail to sell well.

 

[Mopetar]

This seems rather fitting.

I hope that AMD holding off on the launch this long means that more shipments are arriving soon because the scalper prices on eBay are already over $1,000.

 

[Panino Manino]

Again, AMD pushed a card beyond it's optimum ruining efficiency.
RDNA4 can be very competitive, almost match Nvidia in performanceXpower, if only a bigger died existed...

Don't take orders then cancel them. That just wastes my time and screws me out of other opertunities !!!

Like 400 people in line at MC here in MN one hour after open.

I was going to upgrade to a 9070 XT if I could get one at MSRP. The 9070 XT is 45% faster than my RTX 3080 in raster and 30% faster in ray tracing. It has more VRAM, a fresh 3 year warranty, and new computer hardware is fun. The net cost to upgrade after ebaying my old card would be $200-250.

 

[Hail The Brain Slug]

Yeah, MSRP cards were vaporware. I was prepared before release time with every listing, including hidden and delisted cards. Every single MSRP disappeared the second it went live and all that was left were $730+ cards.

This is not the release AMD promised us.

 

[adroc_thurston]

This is not the release AMD promised us.

They can only do so much when the 80% of the market they did not own suddenly decided to pounce.
