“We’ve mentioned this in all our Radeon RX 6000 series reviews; currently, AMD’s most significant deficit is that they do not have a solution at hand that matches DLSS from NVIDIA. NVIDIA wins every, and each time a game adds DLSS. NVIDIA did that very clever; they added Tensor cores in hardware on NVIDIA’s RTX series over two years ago, which will always work out better for NVIDIA. So here we are; a few years later, AMD had decided not to implement a hardware solution as NVIDIA does. As a result of negative feedback, they needed to develop all kinds of ominous ideas to answer the lack of that feature.

I mean, when you think about it concerning technologies like DLSS or DirectML, AMD always will be behind in either image quality or performance. Even with pending DirectML support and now technology like FidelityFX Super Resolution, you need to realize; it still needs to be run over the existing compute engine as some sort of shader code. So no matter how we look at it, there will be a compromise, whereas NVIDIA can offload its ML supersampling to the tensor cores. It’s the sole reason why they implemented these specific DL/AI cores in the first place. Up to last week, we’ve not been 100% sure how AMD is applying FideltyFX Super-Resolution. Even after a briefing with AMD, they did not precisely explain that, but logic dictates this is a simply shader running over the render engine, with two extra passes.”
