FSR 4 Information
On this page, let’s dive into the FSR 4 information AMD has provided. We will post the full slide deck below, with some commentary from us.
FSR, or AMD FidelityFX Super Resolution, began in 2021 as a spatial upscaler only, in this more primitive form, it was able to be very compatible with many GPUs but also really lacked in image quality. Thankfully in 2022 FSR 2 came along, and this is really where it made its mark, introducing a Temporal Upscaler component to the Spatial one. Then, in 2023, Frame Generation was added to the FSR suite with FSR 3, though the image quality component for the Upscaler did not receive an update. That was until 2024, when FSR 3.1 came along and improved image quality and introduced the upgradeable API nature of it. However, one of FSR 3.1’s problems has been game support.
Being introduced alongside the AMD Radeon RX 9070 series is AMD FSR 4, which finally brings ML-Powered Upscaling to the series. Now, this was developed alongside RDNA 4, and hence right now, it works for it, it is not guaranteed to come to previous generations, it could happen, it may not happen, we just don’t know that future, but for right now, Radeon RX 9000 series GPUs only.
How this works is that it all starts with AMD Instinct Accelerators training custom game ML Models, which get fed into the AMD FidelityFX Super Resolution 4 algorithm. Your local Radeon RX 9070 XT or RX 9070 then runs the algorithm using its AI accelerators with high-performance INT operations that it is capable of. The algorithm also works with low-resolution game input, depth, color, and motion vector data for Frame Generation to provide that function as well. The result is a high-quality Upscaled image, with the option for Frame Generation if supported. The models were trained on AMD EPYC and Instinct Processors.
AMD is showing that even in FSR 4 Performance mode, this can resolve images better than FSR 3.1 Native AA mode and definitely better than FSR 3.1 Performance mode or even Native 4K resolution. Just be careful when referencing FSR 4, to specify whether what is being discussed is the Upscaling component, or the Frame Gen component, AMD (and the competition) like to package it all up into the brand name, but really Upscaling and Frame Gen are two separate functions, that perform two very different things, for two very different goals and outcomes.
AMD HYPR-RX gets AMD Fluid Motion Frames 2.1 update. Remember, this is in-driver Frame Generation and does not have access to the Vector Motion data provided by the game. AFMF 2.1 improves image quality by reducing ghosting with better temporal tracking. Importantly, this update is spread across all Radeon generations as it is an in-driver option.
AMD Radeon Anti-Lag 2 is also supported for improved in-game latency but does require game support.

Vs 5070 ti
It is at times like this that I miss Anand's in depth tech coverage.
BTW AMD claiming FSR 4 performance mode is better than FRS3.1 is not saying much but at least is a step in the right direction.
Interesting read... I found it... odd they did comparisons to cards 2 gens old today... made me uncomfortable with what they are delivering.
I can only hope that thanks to the 9070 series prices, 5070Ti prices will como more down to earth and be closer to MSRP (once stock settles).
I don't really see nvidia cutting the 5070Ti price but at least getting them for closer to $750 would still be good news.
Well I think the argument could be that people tend to skip a generation to upgrade, so people upgrading from say a RTX 3070Ti/3080Super can see the benefits of going with a 9000 series.
That used to be true in my house, but that was also when there was a sub-$200 market and top-end was $700. But the last few, it's been more like every 3 or 4 generations...
So much information, it hurts your head. Nice complete article.
The real deal here is can these cards compete with what is out right now, not a 3090 or a 7900GRE or whatever.
I would hope a brand new GPU could stomp a card from 2 generations ago. Next, what can these things do in real-life gaming.
Finally, is there actually a MSRP card to be had? Like anything else, the upper tiers are going to be two or three hundred dollars more, now you're in the realm of $1000 for a GPU ...........I hope AMD does well, we'll see.
Think of the 9070 as a 7900gre replacement & 9070xt as a 7900xt replacement
They will continue to sell the 7800xt & 7700xt until stocks last
7900xtx is sold out everywhere
I currently have a RTX3070Ti and skipped RTX40, not sure if I'll go RTX50, might end up skipping it as well.
Pretty good prices: if I can find a halfway decent 9070 XT late next week @ MSRP in MicroCenter, I'll go for it. It'll be a very nice upgrade over my (aging) RX 6700XT ...
I hope that AMD can keep the supply coming for these because they are very competitively priced (I'll be doing a post on that later).
I went from a 980 to a 3080. Not looking to upgrade this generation either, from either team.
My son though, he has a RX 5600, I think - maybe even an older RX560. He's probably due, but he doesn't care if his games run at 27 FPS, apparently... so I'm not buying him a new GPU. He's old enough he can earn money to get a new one if he wants to.
