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.

We'll see if 9070 MSRP holds or not, but 5070 MSRP isn't anymore real than other Blackwell cards. On Newegg any of the $550 cards are sold out. So are all of the $600, $650, and all but one of the $700 cards.

Anyone paying $700 for a 5070 over a $600 9070 XT is a bit dense. Even though AMD isn't as good as Nvidia at RT in general, the 9070 XT is better than a 5070 on average. There's no reason outside of preferring Nvidia over AMD to buy a 5070 at any price higher than MSRP, let alone at the much inflated costs of $700 or more at which some cards are still in stock.

The 5070 Ti doesn't exist at MSRP either. Market price is closer to $1,100 based on eBay Buy It Now listings because it's completely out of stock on Newegg. Even the ridiculous bundles aren't available.

That's the obstacle to address, and it wasn't. AMD does what they do for their own reasons and no one cares what anyone on a tech forum says, but I'm still saying it anyway. I have a reference point that matters more than anything else when it comes to moving GPUs. I remember what it felt like to be young and excited to build a new gaming PC. I know what it feels like to have a dominant brand name in my head and I know what it takes to shake that name out and allow another purchasing possibility to enter. AMD didn't do that this time, period. It didn't happen. They will rely on market conditions to sell their cards, and I'm sure that will work. But this release is not intrinsically exciting and is in no way sufficient to shift that mindshare inertia in a different direction.
It has to be your friends in math class telling you about that new AMD card that performs like a 4080 but is priced like a 7800XT on black friday. You know you can't pass that up and that's where your birthday money is going. Screw the ray tracing. You want that raw performance for that cost. Now you're excited and now you can justify away all of those Nvidia benefits that you wanted before. AMD didn't do that. Nothing changed here.

The price is largely irrelevant. People make up their minds and then post rationalise on the "better*" feature(s) as a way to justify the increased price.

*Pick latest feature Nvidia is shilling here.

Selling the product at low margins is a sure fire way to make no money.

Im kinda surpised at the lack of cards on websites as of yet. MC, NE, and BH have no cards shown.
Since they are launching tomorrow I was have thought they would have them on the site just not orderable yet.

When can orders open tomorrow?

Looks like theres plenty of stock in the UK. Overclockers posted a picture of a huge pile of 9070XTs, and they are selling them at pretty much MRSP (which is unlike Overclockers!)

I'd bet 5 dollars that's not a solid cube but some worker made a wall that looks like a cube just for a good pic.

They confirmed it was a solid cube (over 1000 units) and they had the same stock of several different models from multiple brands. Some brands like asus and gigabyte they only have numbers in the hundreds.

I still can't get my head around how some NV cards sold the way they did.
AMD need to get into the OEM act with all intent. They have a good landing with Acer (OEM as AMD AIB), and Acer sells very well in Asia. I've seen that the brand was very popular in Singapore, from basic to enthusiast builds at surprisingly good value, and they have a robust supply and support network across Asia. Acer will offer MSRP (or better) value in their PCs.

Also, RDNA4 is very competitive with Ada for typical RT, except in NV Path Tracing pipeline with RR, where games have been tailor made for RTX and DLSS suite. 9070 vs 4070S (4070S ~= 5070), 9070 XT vs 4070 TiS.

I don't know if the boxes showing are all they have or if they've got a lot more behind that, but at a certain point you have so many cards that you might not sell out initially even at MSRP. If you go above it you risk getting no sales if everyone else sticks to MSRP.

If you only got a dozen cards as initial allotment then you already know that there are not enough to satisfy everyone who wants one, so it's much easier to go over the MSRP. If anyone else sticks at MSRP they sell out first, but everyone who didn't get one now comes to you instead and decides if paying extra $$$ is worth it over having to go elsewhere still or to pay scalper prices.

Sounds like they have at the least >4000 units!

We literally have around 2000 units from Sapphire in stock, 1000 from Powercolor and 1000 from Asrock, I feel stock will be fine for a few days.

I'll take that 5 dollars thank you. They explicitly said it's a solid cube.

I rate it a 6/10 for RDNA4 and Blackwell is -1/10.

I would give a 8+/10 for RDNA4. They've got the balance right, including PPA, cost control, and have done an impressive job in both hardware and software. If AMD ensures steady MSRP supply across the world, that's a 10.

If you see from 5700 XT to 9070 non-XT, the same 225W provides for a >2.25x raster performance, while RT performance @1440P over 6700 XT is 2.5x on avg.
The only opportune and underwhelming thing about RDNA4 is that 9070 is $50 overpriced, but even that looks passable because of Blackwell.

Many things can be said, but should not be believed. You have faith in the existence of this cube? Why? Because someone "explicitly" told you it exists? The existence of the cube is just like this release being an amazing deal; they are both likely an illusion. The cards are still too expensive and that cube ain't solid boys.

Overclockers are usually pretty honest about their stock levels TBF.
Plus if stock was low there's no way they wouldn't be hiking those prices as high as they could! They are a good online retailer and I use them a fair bit but they aren't normally slow about upping their prices!

I think a lot of them were scooped up by scalpers. Even if you're paying a bit above MSRP, if you think you can flip it for an extra $100-$200 (or even more) on eBay you'll buy it. Even if I had managed to land a 5070 Ti at MSRP if I could get the $1,100 that many are going for on eBay I'd be tempted to sell it myself.

Until NVidia can result the channel the ridiculous prices will continue. Supply may be so bad that the next batch of cards also gets bought up by scalpers because the incredibly low supply creates a price bubble that won't fully deflate for a while. Availability of $600 9070 XT cards will help as some people will buy what they can get even if it's not what they want, but I'm not even sure if the RDNA 4 cards will hold at MSRP.

Many times the perception of shortage drives panic buying which does more to create the shortage than anything else. For a recent example, look at the shortages of toilet paper during COVID. For all the symptoms of COVID, pooping more was not among them. People weren't using more toilet paper, but once people thought there might be a shortage everyone rushed to buy more than they needed causing a shortage. Even people who already had more toilet paper than they could use in the next two years would go buy more as soon as it hit the shelves because they feared running out later.

It doesn't quite match up, including that. Also see their individual game benchmark numbers. They are beyond margin of error.

It does match up. In TPU, its +56% in RT, +35% in raster at 4K (Nitro) vs 7900GRE. Average those two numbers and you have +45%.

If they thought they could win, they would. AMD played their own game and to their own advantages with Ryzen as well, and when they had an opportunity to pounce on Intel they took it. Some of that started by building mindshare with the OG Ryzen. Even if people didn't buy one, it got a lot of buzz and AMD built on that over successive generations.

I'd buy a 9070 XT over a 5070 Ti at MSRP. I don't give a toss about RT or frame generation, so it's purely a raster performance consideration. I'm not paying $150 more for an extra 5% performance and 4 GB less VRAM that may become an issue in the future.

What review did you watch? In the 18 game average the 9070 XT was 6% slower than the 5070 Ti in 1440p and only 1% slower at 4K.

I don't personally care about RT and neither card will run acceptable frame rates without using upscaling so even if I wanted an RT card I wouldn't consider the 5070 Ti.
