1. While it is true we have no idea how the Switch 2's Tegra will be like, a low TDP mobile 3050 level of performance (like the one in the video) is in line with the upper-end rumors, especially if they switched from Ampere to Lovelace as some of the more recent rumors allude to. Furthermore, it doesn't invalidate the point I was making that DLSS is a significant improvement even for the lowest-end Ampere chips. The 25W mobile 2050 (which is technically GA107, despite the 20 title) also benefits significantly from DLSS despite being a significant cut down relative to the 3050 mobile. It's often the difference between a game being unplayable or being lockable to 30fps (or 60fps.)  

Just trying to keep peoples expectations in check.

The 3050 mobile chip is still 2048 functional units which can boost to 1.7Ghz and is backed by upwards of 192GB/s.

That is still going to out-perform a fully-equipped AGX Orin 64GB, let alone a cut down variant like the AGX Orin 32GB or even the Orin NX 16GB.

Part of the reason is TDP, the 3050 can clock higher and more consistently as it's not sharing TDP with a CPU core cluster and has a higher default TDP to start with.

Provided Nintendo opts for Orin in the first place.

1.7Ghz boost is only possible in the top-powered model (80W.) The lower TDP models (the one in the video was a 45W model with a max boost clock of 1.35 Ghz) have much lower base and boost rates.

Also the RTX 3050 mobile is VRAM limited with only 4GB. In a game like Final Fantasy 7 Intergrade (among many other more recent releases) 4GB is a significant bottleneck at 1080p.

A Lovelace Tegra with a TDP of about 15-20W and 8GB of allocated video memory available could be competitive with an RTX 3050 mobile @35W-45W. Especially in a closed-platform where game optimization can be targeted. I'd expect it to be even more true as games continue to become VRAM hogs. 

"The GPU is expected to have between 12 and 16 Stream Multiprocessors, which for Ada Lovelace house 128 cores each, for a total of 1,536 to 2,048 CUDA cores.

All told, the Switch successor is expected to have a pair each of Arm Cortex X4 and Cortex A720 cores backed by a quartet of Cortex A520 cores, this 12-16 SM Ada Lovelace GPU, and somewhere between 12 and 16 GB of memory, which we presume to be LPDDR5. Knowing that an Apple M2 Pro MacBook Pro has 200 GB per second of memory bandwidth on a 128-bit memory bus, we're hopeful the Switch 2 will be in the ballpark of 150-200 GB/sec, assuming a 96-bit bus for 12 GB of memory or 128-bit for 16. It would be a monster compared to the current Switch while still potentially being something that could fit into the thermal and power profile of a tablet. The video mentions the SoC might be made by MediaTek. 
"

I don't think it necessarily will happen, but it is the upper-limit of possibilities. 

Edit: It wouldn't be surprising at all if the performance difference between the Switch 2 and an RTX 3050 35W was less than the performance difference between the RTX 3050 35W and the RTX 3050 80W.
