By the time 2024 comes around and a Switch successor has launched mobile hardware will be at a point where it could match the performance of a Series S, yes. However, expecting this to be in a product that is supposed to sell for sub-400 and powered by 10-15 watts is not likely to happen. Nintendo's history with mobile hardware shows that they aren't going to go for the most powerful product, and the recent Nvidia leak practically confirms this.

That being said, there is additional information that I would like to share. We know that the leak mentions Orin, but many don't know that the CUDA core count was found as well. It's about 1500 for the CUDA core count. GA10B has 2048 CUDA Cores with 4TFLOPS of FP32 compute @1Ghz. Given the information about the core count, Switch 2 will be capable of about 3TFLOPS of FP32 compute @1Ghz. That said, DON'T expect 1Ghz. If the Switch 2 follows it's predecessor then the clock speeds will be pretty sharply reduced (i.e. about 307Mhz-768Mhz. Therefore, portably we can expect around 1TFLOPS of performance, and docked we will get about 2.5TFLOPS docked performance. Provided all of the information in the leaks is up to date and accurate (remember things do change). Personally, I think this is VERY good even if it doesn't match the power of the Series S.

I've read 1.536 core count some time ago as well (6 times the Switch), but if I'm remembering correctly it was more of a guess from the leaker.
It's not a random number since the Switch 2 is supposedly based on Ampere architecture and Ampere GPUs are modular. That is exactly the count of a single Ampere GPU processing cluster (the RTX3080 has 7 for example).

About clock speeds it's reasonable to expect lower clocks compared to OEM form factors (considering both the size of the device and battery constraints) but it's also reasonable to expect higher clock rates compared to Switch1 due to improvements in the chip manufacturing technology. Remember the Switch1 was originally designed around a 20nm chip, here we are talking at least of 8nm.

That said I wouldn't trust too much rumors atm as it seems they are based more guesswork based on similar known architectures. TBH 1.536 cores seem like a lot for essentially a mobile device based with an 8nm chip, I would say that would be absolutely the upper limit.
