AMD's FSR Redstone uses machine learning to achieve parity with Nvidia DLSS

The next evolution in FSR frame generation

www.tomshardware.com

As part of its Computex 2025 announcements, AMD has given gamers a sneak peek at the company's major update for its FidelityFX Super Resolution (FSR) technology. Dubbed FSR Redstone, the upcoming installment will bring many new features to match rival Nvidia's Deep Learning Super Sampling (DLSS).

AMD is already plotting ahead and preparing FSR Redstone as the next substantial upgrade for FSR.

Although AMD did not provide specific details, the chipmaker emphasized three features to be included in FSR Redstone: neural radiance caching, machine learning ray regeneration, and machine learning frame generation. Some of these features might sound familiar, as they are already part of the Nvidia DLSS suite.

AMD states that neural radiance caching effectively learns how light reflects within a scene. The objective is to predict and store indirect lighting assets in a cache, which can subsequently be used to generate heaps of other rays. Logically, this helps accelerate path tracing.

Ray regeneration is equivalent to Nvidia's ray reconstruction. This feature leverages a trained neural network to regenerate pixels that couldn't be accurately traced. Thanks to machine learning, it can predict and filter grainy noise in real time.

It's already pretty hard to tell between their quality settings. It's time to compete on how far those internal resolutions can be pushed down.

I have been hearing this since FSR2. I don't believe em anymore.

 

[Unknown Soldier]

Umm, did an AI write the article?

Machine learning is literally how all the AI upscaling methods work

 

[Mister Wolf]

Competition is good. Hopefully they can achieve parity with DLSS4. By the time of my next GPU purchase they may become a contender.

Uh FSR4 is an huge step above; about what we can't believe anymore?

 

[Dr.D00p]

So, Path Tracing when combined with FSR4, will no longer crash framerates on AMD cards....cool.

About time.

 

[Trilobit]

What's the difference between DLSS and machine learning?

 

[Rentahamster]

Parity? I'll believe it when I see it. AMD's got a lot of work to do, but I hope they and Intel progress far enough in the GPU space to bring some proper competition into the arena.

 

[Gaiff]

What's the difference between DLSS and machine learning?

DLSS is a form of machine learning or rather, it uses machine learning. It stands for Deep Learning Super Sampling.

 

[ItsGreat]

So are these algorithms doing the similar to this? Or are they just the mathematical magic described in the video dressed up as AI?

 

[daninthemix]

Source: trust me bro.

 

[Klosshufvud]

AMD have been talking about parity with DLSS even before we had combustion engines.

Does it use ML for fixing the HDR for Samsung TVs on Windows when using Freesync Premium?

No it's not.
Several unspcalers don't use AI. Such as Epic's TSR, AMD's FSR1 and 2, Nvidia's NIS, Qualcomm SGSR, among others.

Those aren't AI upscalers tho

You are right, I didn't read that he was talking only about Ai upscalers.
I need to have coffee before posting....

FSR doesn't require hearing, it requires seeing.

If you see it for yourself you'll see that it's pretty damn close to dlss4, which is remarkable.

 

[dgrdsv]

*Feature parity.
We'll see about quality and performance.

 

[Trilobit]

DLSS is a form of machine learning or rather, it uses machine learning. It stands for Deep Learning Super Sampling.

So the title, if it concerned cars, could be: Redstone uses wheels in their cars to achieve parity with Porsche?

It's FSR4 that bad? I can understand FSR2 but with FSR4 the difference with DLSS start to be really subtle it seems.

I think the point they're trying to get across - perhaps poorly - is that up to FSR3, AMD did not use machine learning. It's why they were able to have FSR run on pretty much anything from Turing and up. With FSR4, they started to use ML, which is why it's not available on all the same cards FSR3 is.

 

[Klosshufvud]

The issue with FSR4 is it being exclusive to a recent GPU only a fraction of AMD owners have and being exclusive to a certain select amount of games. Meanwhile DLSS is supported across hundreds of games (most high-end games in recent years) and supports Nvidia GPUs from five years ago. And despite that, FSR4 is still inferior to the DLSS that 2xxx series Nvidia cards can run. This is a decisive defeat for AMD and one that may cost them the entire dedicated GPU segment. Too late, too little, too expensive.

That is only true in part.
The list of FSR4 games is constantly increasing with each new driver release. And if we consider Optiscaler, then the list increases into the hundreds of games.
So although Nvidia still has an advantage there, it's not as big as you think it is.

Yes, it's a major problem that FSR4 is only available on the 9000 series. But according to people on the AMD's Vanguard program, AMD is porting FSR4 to RDNA3.
But we also have to consider that Nvidia did the same thing with Frame Generation and the RTX 2000 and 3000 GPUs. And did it again with Multi Frame Generation, and the RTX 2000, 3000 and even the 4000 series.
Meanwhile AMD allowed Frame Generation to be used on all GPUs, be it AMD, Intel or Nvidia, from many older generations.
So in this situation, AMD and Nvidia have similar problems.

FSR4 Is very close to DLSS4, in a few aspects it matches DLSS4 and in disocclusion artifacts, it's better than DLSS4. But you are right that overall, DLSS is still the best upscaler in the market.

 

[rofif]

isn't fsr4 just that? and dlss2? And pssr?
These are are using machine learning and motion vectors for deeper integration with the game contrary to fsr2

All temporal upscalers use motion vectors, color buffers and depth buffers for upscaling.
The AI upscalers just use an AI pass to improve and clean up the image.

Unlike their cpu business where they actually innovate

AMD really STILL are two separare companies: AMD and ATI. They just rebranded ATI and are still doing the same shit

Eh, I think that's probably a little too alarmist. Like winjer said, Nvidia does the same thing. RTX 2000 and 3000 only supports some DLSS4 features, RTX 4000 supports more, and RTX 5000 supports all.

I think strategically they made the sound decision. AMD was never going to get from 0 to FSR4 without going through the iterative process it went through. Obviously they started later than Nvidia, but to get here in this short amount of time is impressive, and if Redstone can get them closer to whatever the latest DLSS is, that's most of the battle won. Everything else is marketing and cost control.

TL;DR: Radeon will be fine.
