they really need to sort out that pesky hdm2.1 issue

FSR4 is leaps better than FSR3. Would be amazing for the GabeCube to have this enabled

Explains why the GabeCube is planned for an early 2026 release and not this holiday season. I bet Valve will want this ready because FSR4 in performance mode looks much better than FSR3.1 in quality mode.

GPU is still RDNA 3
It doesn't have hardware MLA capability
This is just an experimental gimped down version of FSR 4

Pretty sure RDNA3 has AI accelerators that support MMA and WMMA instructions.

Not disputing the fact that the performance penalty will be steeper on RDNA3. The point is in spite of that, you're still better off running FSR4 in performance mode than FSR3.1 in quality mode. I don't think Steam Machine users will be particularly happy if they use FSR3.1 only to discover that the image quality is poor even at the highest quality setting.

Eh, I've already seen the gimped experimental version of FSR4 on RDNA 3 cards, and it looks considerably better than FSR3.
The CPU they at least picked for the Steam Machine will also at least help with processing the upscaling, with I think a 9-13% drop (vs FSR3.1) I've seen projected with similar hardware, vs if you put this on a weaker chip like some have tried on the Steam Deck with the RDNA 2 chip...it was like 25% worse.

This works on steam
Deck right now with a decky plug in and as youd expect its alot better than FSR3 like night and day.
Those low res blocky upscalers are cleared right up and its incredibly easy to inject into games. Its literally a copy and paste into launch options.
The only downside is it is quite heavy on the gpu compared to fsr 3 since the sd does not natively support it.
I have no doubt fsr 4 will be on steam machine and if it isnt it will be unbelievably easy to inject and on RDNA 3 should be decent.

I can build a PC and don't understand what I'm reading in this thread.
But I'm so 100% in.
Or I'm going to wait it out and see.

It means steam machine will have fsr4! Huge deal since the spec is so low. This can effectively put it a little ahead of ps5 in terms of what you get on-screen, even though it is a little behind in raw spec.
Also helpful for anyone with rdna3 and 4 cards on linux. We knew it was coming but now we know it's on time for the steam machine.

Ah right on! That's awesome!! It's the AMD speak that's getting me (Nvidia owner).
From what I'm gathering, FSR4 is a much better leap in upscaling tech compared to previous efforts?
Kinda like how DLSS is pretty darn good these days on the Nvidia side? I've been a huge fan of it, myself.
And RDNA 3 vs 4 is the generation of GPU? Kinda like Nvidia has 40xx, 50xx, etc.?
It sounds like FSR4 was meant for RDNA 4, but they found a way to make it work with RDNA 3, which is what Steam Machine will be?

They can't get the cert without using closed-source code or something like that

There are two ways:
Nvidia way - add the certs within the firmware.
Intel way - add a DP-HDMI converter inside the GPU.

lol....if it's because of open source then that's absurd

Depends who you ask, but imo the difference between fsr4/dlss3/dlss4 is at the point where we're splitting hairs. I'd say amd caught up on it.
Yah fsr4 was introduced as just rdna4. But some people have got it working on rdna3 and it works well enough to be worth using.

Yeah seems like AMD has caught up, which is great! I don't look at every pixel, myself.
I was already buying the Steam Machine. If this works relatively seamlessly or with minimal setup, then this is fantastic news!

Likely the Intel way is easier, because I don't know how AMD would do it on Linux given the driver firmware is open-source.
Or just bundle in displayport to hdmi 2.1 cable dongle with their GPUs. HDMI forum sucks anyway, they charge more in licensing fees than most other connector standards.

My impression of doing DP -> HDMI 2.1 conversion is that it's a huge mess, passive adapters will not have HDR and VRR support and trying to find an active adapter which will transmit HDR is difficult but VRR is impossible
Durin
Member
Pretty much any conversion cable can be a pain, unless you check user reviews to look up the features specifically. USB just a standard can be a mess, because some cables will support that data speed you want, but not enough wattage of power, etc.
My friend did solve this problem with this Cable Matters DisplayPort to HDMI 2.1 (amazon) cable on his 9070XT. He was able to get 4k 120hz with HDR and VRR working, but like you said is an active adapter. I do wish AMD just went with the Intel approach of doing the conversion on the chips themselves to get around this though.

Is it true to say that the 8GB of VRAM will also limit FSR4's capabilities of the GabeCube?
MisterXDTV
Member
indirectly: FSR 4 requires a bit memory but it's also true that if you go above 1080p as output resolution then 8 GB could become a limit with 1440p or higher
Still, we are talking about a GPU with 35 TOPS while RDNA 4 starts at 172 TOPS for the OEM vanilla 9060

The main problem is the lack of TOPS power altogether. It could "work" on GabeCube but the performance cost might be too much for most games.

I was thinking the point would be eventually have FSR 4 support without having to use mods, but not 100%
It's not the leaked int8 model, this essentially emulates FP8 model on older RDNA cards using FP16/int8.

I wonder how that is performing then.

The firmware is not open-source. It contains DRM and other technologies that each manufacturer keeps secret. When you install the GPU firmware on Linux, you are installing a binary, not the source code.
