1. Yes, the switch 2 with DLSS will close the power gap unlike anything we’ve seen in our life time.
2. DLSS is exclusive to Nvidia
3. I mean Arm cpu is breathing on x86’s neck. That wasn’t possible years ago. Mobile computing has progressed so fast. Faster than desktop.
Bear in mind that both AMD and MS are working on their own competitors to DLSS. We could see developers using those on PS5 and Xbox Series X before the end of the generation, to run games at native 1080p or 1440p AI upscaled to 4K, to free up resources to use to push graphics further instead. Developers could also use AMD's or Microsoft's DLSS competitor to run Series S games natively at 720p or 900p, AI upscaled to 1440p. I don't know if DLSS will magically close the gap for Nintendo.
The good news for Nintendo is that they should be able to release a Switch 2 with specs that are pretty close to Xbox Series S by about 2023, close enough that they shouldn't have too much trouble convincing 3rd party developers to port to Switch 2. Something like a 3 tflop docked, 1.5 tflop handheld GPU, best ARM CPU available in 2023, and LPDDR5 RAM should be good enough to get 3rd party ports again. The main issue for Nintendo is going to be storage, how to get games that were built from the ground up for NVMe SSD's onto Switch 2. Internal SSD for digital gaming on Switch 2 won't be a problem, a 500 GB internal SSD for Switch 2 should be more than affordable by 2023, with expandable internal storage made possible with SDXC Express cards, which are available in sizes up to 2 TB and have either 1969 MB/s or 3938 MB/s speeds depending on rather 1 or 2 PCI Express 4.0 lanes are used. The issue is what to do about physical games on Switch 2. Game cards for physical Switch 2 games that are fast enough for next-gen game ports could be very expensive, I could see the price of physical games being $15-20 higher than digital versions on Switch 2.Last edited by shikamaru317 - on 09 October 2020
