That would require quite the jump in performance. Even the upcoming Snapdragon 8cx only reaches about Switch GPU power (and a Tegra X1 running at full speed still has a 30% faster GPU than that!)

More probably, it's duable to a technicality: XBO calculates FP16 (half precision) at the same speed as FP32 ("full" precision), while mobile chips can calculate those at twice the speed. So in FP16, they could catch up to XBO in GFLOPS due to this. But videogames need FP32 most of the time, so an A12 Bionic wouldn't be able to handle the graphics in those games in any way.

To me its just interesting how much Mobile is closing the gap. December should be a great month for Nintendo. Im looking forward to gaming in 2019.

It's not closing the gap.

Even in 7nm, anything close to XBO power in such a small casing like a tablet would totally overheat and shut down in minutes, if not seconds. It still needs active cooling to achieve that, something tablets normally do not have.

A Ryzen 5 2500U found in fairly thin Laptops comes close to XBO power, a 2700U would actually surpass it. But in both cases, that's peak power, and I don't think they can keep those GPU boosts over prolonged times even though they have a 15W TDP, about 3 times what tablets have. In other words, while the A12 could reach XBO power (and, like I said, even then probably just on a technicality), there's no way it could hold that much power.
