I'll add a few more things to the conversation. See the thing with DLSS is that you don't need Tensor Cores to do it per say. Tensor Cores help greatly but both DLSS and DirectML can be done without Tensor Cores and we have real proof of concept with DLSS and Control. Here's a brief history on how it went.
Target Resolution: 4K
DLSS 1.9:
Done Through:
Shader Cores
Pros:
Looks quite similar to Native 4k Image
Performs Very similary to the Rendering Resolution such as 1440p
Can be done in any GPUs that has INT-4 and INT-8 support including RDNA 2 if Nvidia wanted to
Cons:
Needs Per Game AI Training
Going below 1440p Render Resolution starts to look bad
Noticeable Artifices and Ghosting when in Motion and wasn't very good at dealing with Transparency
DLSS 2.0:
Done Through:
Tensor Cores
Pros:
Looks very close to Native 4k image, sometimes even better than Native
Motion and transparency issues are mostly gone
1080p Render Resolution looks better than DLSS 1.9's 1440p Render Resolution
Doesn't Need per Game AI Training as the AI is now Generalized. Just needs in-engine support
Cons:
Requires Tensor Cores
Results:
Fap worthy performance and image quality
Now according to Nvidia, they needed Tensor Cores because the Shader Cores are too slow. Technically speaking, they are correct. The AI acceleration in a 2060 is twice as fast as a Series X thanks to the Tensor Cores. And because of that, Tensor Cores I believe are certainly needed to achieve what we have. But that doesn't mean that something isn't do-able with just Compute Units as DLSS 1.9 shows.
The problem with AMD is that their vision on how to approach this is so behind that it's going to take time. They haven't even figured out on which method to even go let alone starting to develop for it. Most likely, we won't see anything until 2022. And thanks to DLSS 2.0's massive improvements and it's ease of implementation, there will be a ton of games that will get it while everyone else waits for AMD's solution. The kicker of course is, once AMD does come out with their Super Resolution, it will work on Nvidia's GPUs as well and won't be anywhere close to DLSS in terms of performance and image quality for a long time.
