Intel XeSS upscaling will work on most Nvidia and AMD graphics cards, but not all

Written by Neil Soutter on Wed, Sep 1, 2021 12:42 PM

Intel recently confirmed that they are working on their own version of an upscaling technique much like DLSS or FidelityFX Super Resolution (FSR), known as Intel XeSS. Like DLSS, the technology will be using AI for upscaling, and like FSR it will be compatible on most hardware including from other brands.

But does that mean it will work on every GPU available? Unfortunately not, the limitation does apply to certain generations of hardware due to compatibility. In short, Intel uses their own XMX acceleration within their upcoming Alchemist GPUs (based on the Xe-HPG architecture) specifically for upscaling, much like Nvidia’s Tensor Cores.

However, for any non-Intel Xe-HPG graphics cards, they will be using the DP4A instructions in order to use Intel XeSS. It’s not quite as efficient as XMX, so you’ll get the best performance and quality out of XeSS on Intel Alchemist GPUs when they launch in Q1 2021, but at least it works on other brands of hardware.

Most modern graphics cards support DP4A, but older hardware will struggle a bit more. Nvidia seems to have more support for older hardware, as XeSS will be supported on RTX 30, RTX 20, GTX 16, and GTX 10 series cards. Whereas on AMD’s side, only the recent RX 6000 series GPUs will officially support it.

And, of course, Intel Xe-HPG-based graphics cards will support XeSS, and as mentioned previously will also offer the best performance for the upscaling tech due to the dedicated XMX acceleration. Intel Xe-LP GPUs will also support the tech, but only through the DP4A instructions like Nvidia and AMD, and older Intel generations will not support it at all.

So then, which cards will actually support Intel XeSS when it launches? Here’s a quick breakdown:

Intel XeSS expected compatibility Intel Nvidia AMD
XMX Intel Xe-HPG (Alchemist or higher) None None
DP4A Intel Xe-LP Nvidia Ampere (RTX 30) / Nvidia Turing (RTX 20 + GTX 16) / Nvidia Pascal (GTX 10) RDNA2 (RX 6000 series)
Not supported Older architectures (Gen 11 or older) Older architectures (GTX 900 series or older) Older architectures (RDNA or older)

*Be advised: this is not officially confirmed by Intel, but instead deduced by what Intel has said so far. It's possible the list of compatible GPUs may grow at launch, but so far this is what we can expect.

What do you think? Are you interested in Intel XeSS? Do you think it will be better, worse, or the same as Nvidia’s DLSS or AMD’s FSR? Let us know your thoughts!

Do you think Intel XeSS will be better or worse than Nvidia DLSS or AMD FSR?

So GTX 1050 Ti can use XeSS but Vega 64 or Radeon Radeon vii or 5000 series can't !!! wow nice job AMD.

Auch for AMD side of things with RDNA2 only being supported, of course provided this ends up being real. Makes me wonder what is the issue with RDNA 1 or even Polaris.... I get it they don't want to go all the way back, but still, that is pretty restrictive on AMD side, especially compared to nVidia. Still, since it is not officially confirmed, I do feel like they will want to add more support on AMD side.


Unless AMD shortage is so bad that even Intel can't get cards for testing... :-D I mean, jokes aside, at least locally AMD supply was way worse than nVidia, except for 6600XT which lasted impressive few days.

Bl;ess the GTX 10 series. The accidental boon that Nvidia can bever seem to get rid of. Also good going Intel.

So the gpu needs SOMEKIND of AI cores to function okay thats good IMO. After the fiasco of FSR i think it's good to see another option

Im more interested in how intel is going to optimize its dgpu drivers for over 20 years of games...
