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.

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...

My expectation is that 9070 gre will not get a worldwide release until prices settle down & fake msrp = real msrp (=$400?)

I'm talking about the 9060 XT, not the 9070 GRE. The GRE would presumably be $500 if it was available WW any time soon.

Oh ok. I expect 16gb 9060xt to be $350 & 8gb to be $300 (but all fake msrp)

US prices (esp. in microcenter could be a question mark due to the uncertain tariff situation)

NomanA · Apr 19, 2025

I was finally able to get a 9070XT. It's ASRock Steel Legend and it was there on NewEgg for some time. The price of $699 was only $30 more than what I almost paid for the same card on release-day standing in a line at a local store (they ran out of this card just when my turn came) . There was enough time to login, do two-factor authentication, fill in credit card number and then do another verification with the credit card company. The card was available even five minutes after I got the order confirmation mail. The availability is improving but even the official channels have now bumped up the price to about $850 on average. So, $699 wasn't too bad. This card is white, so maybe that narrowed the buyer pool a bit and resulted it in being there at NewEgg for more than five minutes.

This bit me yesterday. Hard to build driver reputation when this goes on for over a month.

9070XT and Zoom Workplace issue

Dear AMD staff,

I would like to inform you of what may be a compatibility issue with the 9070XT; specifically, involving Zoom Workplace.

I just switched my GPU to the RX 9070 XT this afternoon. After installing the GPU, I downloaded and installed AMD Windows Driver (Version 32.0.13031.2000) alongside the Adrenaline software suite (Driver Version 24.30.31.02-250212a-412851C-AIB). I did some benchmarking, and the system has been stable---thank you, it's been a fun experience.

However, when hosting a client meeting via Zoom this evening, I noted that their video was frozen during the Zoom call. I did find a work-around in that when sharing screens the user-videos would act as expected. However, in the standard main room of Zoom, again their video would freeze.
Whilst this is not urgent for me personally, as there is a work around, I imagine it may affect others. I would appreciate it if you could investigate if this issue can be resolved on your end, or whether it is an idiosyncrasy on my end.
If you require any system specific information please ask, or perhaps it may be a quirk of remnant Nvidia drivers.
Yours sincerely,
Andrew J Barnes

Wasted about an hour rebooting and looking around when I should have been chatting with my friends.

Shouldn't you be complaining to Zoom and not AMD?

I didn't complain to anyone. It's a most likely a codec issue. Regardless AMD has known about it for over a month and doesn't even acknowledge it.

Known Issues

System crash may be observed due to a memory leak when using SteamVR on some AMD Radeon™ Graphics Products, such as the Radeon™ RX 9000 series. Users experiencing this issue are recommended to turn off Motion Smoothing in SteamVR settings.

Performance logging notifications from AMD Software: Adrenalin Edition™ may appear while using the Right Alt + L hotkey if the Microsoft® Windows® display language is not English.

Intermittent crash of AMD Software: Adrenalin Edition™ may be observed while playing Marvel's Spider-Man 2 or Ratchet & Clank: Rift Apart with AMD Image Inspector enabled. Users experiencing this issue are recommended to disable AMD Image Inspector as a temporary workaround.

Lower than expected performance may be observed when using YouTube on the Microsoft Edge web browser immediately after a driver install. Users experiencing this issue are recommended to restart Microsoft Edge and relaunch YouTube as a temporary workaround.

After using the AMD Cleanup Utility for Windows®, the AMD Bug Report Tool may appear intermittently during a new driver install on AMD Ryzen™ 7000 and above series processors paired with AMD Graphics Products.

After completing a driver upgrade on certain laptops, users may experience intermittent failures for the integrated camera to start. Users experiencing this issue are recommended to use the AMD Cleanup Utility for Windows® and use our previous recommended driver, available here.

Stutter may be observed while playing games with some VR headsets at 80Hz or 90Hz refresh rate on some AMD Radeon™ Graphics Products such as the Radeon™ RX 7000 series. Users experiencing this issue are recommended to change the refresh rate as a temporary workaround.

Installation progress may persistently display 0% while installing chipset drivers using AMD Install Manager.

Installation progress may persistently display 0% while installing AMD Chat within the AMD Software: Adrenalin Edition user interface after upgrading to AMD Radeon RX 9000 Series graphics products.

Maybe you should complain to Zoom then.

Schmide · Apr 19, 2025

I'm not defending zoom but codecs are the drivers responsibility. The platform is responsible for almost nothing. Allocate memory, query codec, pass, receive display data.

You can use the software version of the codec and it works. You can use a different card and it works. (yes I have more than one AMD card and a couple nvidias)

There is one odd player out and it's 9070 xt with AMD's drivers.

There is absolutely no reason for you to divert!!!

Edit: Complaining to zoom is akin to complaining to the monitor companies for the nVidia blank screen issue.

If you have any ~~complains~~ issues, why are you posting It here? Make a different thread.

It's a post about driver issues with RDNA4 the same way we posted about driver issues with Nvidia cards in the Blackwell thread and the same way we discussed the state of driver maturity in the Intel Arc thread.

And shouldn't that be in a different thread regardless of which brand? Doesn't look like we have something like that.
Because this looks like a driver issue rather than a problem in HW(architecture).

@GTracing I meant a common thread for driver issues, not limited to just AMD. But maybe It would be even worse than just dumping everything in a single thread like this one for each respective brand.

Looks like AMD will indeed release Radeon Pro N48.

Despite what the title says, this is the de facto thread for all things RDNA4. Are we going to make a separate thread for RDNA4 pricing? RDNA4 upscaling? RDNA4 aib designs? RDNA4 overclocking?

As much as this is a driver issue. It's more a commentary on AMD's lack of response to a driver issue. The linked thread's poster was very nice and posted at AMD with the exact same issue I had. (though I had it over a month later) There was no AMD response on the thread and it didn't make it into the "Know Issues" for the driver. Maybe they are just slow, maybe they just don't care. AMD typically releases quarterly driver updates, and that should be fine for incremental updates for mature stacks but this is a new launch with new errata.

Crux of the matter is they revamped their hardware encoder/decoder stack and if they are having trouble with old common codecs on a mature platform, they need to do better.

As for software vs hardware. They walk hand in hand. You can't run one without the other.

I'm not getting rid of my cards. I'm very good at troubleshooting. This is all about perception. Not where to divert the issue.

Don't expect solving issues on AMD forums or AMD subreddit (although there is a higher chance on reddit as there is one user there that is a vanguard on radeon drivers). No AMD engineer is looking at AMD forums...it's a waste of time.

Then that's a problem that leads to their bad reputation. Which is what I am expressing.

How does the saying go. The coverup is worse than the crime.

I put forth an experience that I had. I've been met with diversion, hyperbole, exclusion, and so on.

Their drivers aren't as bad as their reputation, but it's easy to see how it got that way.

APU_Fusion · Apr 20, 2025

Ahhh. We are suddenly back to AMD makes terrible drivers better stock with nvidia (unwritten but implied). It. Is the same thing every time. Nvidia drivers have not been glowing lately either.

I wonder if the 32gb model is aimed at AI? Already sick of AI in every product name.

This is offtopic so I'll try to make myself more clearer.
I was just trying to help by pointing out the AMD forums and to some extent AMD subreddit are kinda useless for bug reports.
It's just a community based forum where people help each other out. There is no where mentioned that AMD community forums are some sort of tech support forum.
So if you want to submit bug reports do it with the bug report tool that is in the drivers.
If you feel it's easier to write a forum post with pictures/videos or whatever helps to reproduce the issue on their end, you can also post a link to your forum post in the bug report.
I submitted many bug reports mainly with video glitches in games and they were fixed in the next 1-2 drivers...sure some bugs were not fixed or partially fixed but 90% of my bug reports were fixed. that's all, I'm not making excuses for AMD when they mess up and they do. All companies do.

Again. This isn't about helping me help AMD or zoom. This is my mini review of some issues and commentary I had with one of my 9070 xt s. (yes I have 2) Every review posted in this thread is a commentary. As is a lot of other offtopic stuff. Which extends to you telling me how to deal with AMD.

I'll push it back in the right direction with a review.

This is a plus for RDNA4 and one of the reasons the 9070 xt should be a desired product. Plus for h264 and h265 encoding. Minus of AV1.

The flip side is they are having troubles with old codecs.

Up until now no one ever considered AMD for encoding/decoding. If I have to wait till June, 3 month cadence for drivers, to get back to basic functionality. I'm kind of disappointed.

BTW I sent a ticket to zoom with logs

I wonder if there is any wiggle room to improve AV1 encoding with driver/software updates.

It's been like this since two or three years ago, just set DX9 inside zoom and you'd be good to go
