AMD Noise Suppression For Radeon GPUs Accidentally Leaks
Somewhere in Texas, an intern has (probably) just been let go from AMD. Over on the official AMD subreddit a video popped up yesterday titled “Elevate Your Audio Experience – AMD Noise Suppression.” The video is now marked Private, but like all things on the Internet people were able to save a version of it. As the title suggests, an upcoming driver will allow Radeon GPU owners to eliminate extraneous noise in video, voice calls, and when gaming. However, it’s not clear which GPUs will support this technology, or when it will launch.
The Redditor who shared the illicit video posted some details before it was taken down. According to them, noise cancellation is a setting that will appear in the Audio and Video tab of an upcoming driver. Activating the feature “will install a new virtual audio device that you can use in your applications.” The video, which was reposted by Tom’s Hardware, says it’s powered by a “real-time deep learning algorithm,” which is a bit buzzwordy. The algorithm delivers two-way noise reduction for both input and output. Finally, it works across apps and games, but no software titles were listed.
Since this looks legit, we can do away with the “if this is true” speculation. Therefore, it seems AMD wants to deliver something akin to Nvidia’s RTX Voice. That’s a feature available on Nvidia GPUs that uses their AI capabilities to remove background noise from livestreams, voice chat, and video conferencing. It can be especially useful for streamers with mechanical keyboards, for obvious reasons. Despite its RTX branding, it’s been discovered to work on older GTX graphics cards as well.
This sort of technology appears to be gaining new popularity. Recently a block diagram of Intel’s 14th generation Meteor Lake CPU was posted, and it mentioned something similar. Under a section describing its vision processing unit (VPU), it lists “Broad noise suppression” as a feature. The same section lists Intel GNA 3.5, which is a new version of its Gaussian and Neural Accelerator. This low-power, neural co-processor is capable of features such as noise reduction and speech recognition.
As always with AMD, it’ll be interesting to see if this technology works on older Radeon cards or if it’s reserved for RDNA / RDNA2. Or, if they are only going to allow it RDNA-based cards. The worst outcome (though it seems a bit unlikely) would be AMD reserving this feature for RDNA3 GPUs. Older architectures like Polaris and Vega are not supported by recent AMD technologies like Radeon Super Resolution. AMD’s FidelityFX Super Resolution (FSR) 2.0 also requires at least an RDNA2 GPU.

Nvidia AI Compensates for Your Poor Photography Skills by Erasing Noise From Images
Even if the Noise2Noise system has never seen an image before, it can de-noise it to get something very close to the original.
New Google Patch Reduces Spectre Performance Impact to ‘Noise’
When Spectre Variant 2 patches rolled out this year, some servers, particularly those with older Intel CPUs, saw performance declines. Google is working with MS to make sure we get that performance back.
