Why are there no snapdragon 8 gen 2 sbc’s?

This might be a dumb question but why are there no modern arm chip sbcs with soc’s like snapdragon 8 gen 2? A Chinese handheld like the Odin 2 has the chip and everything else for only 299usd but a dev board with the same chip costs 1299usd…

And also those dev boards require dc power while smartphones are able to run the chip on li-ion battery packs for long periods of time. Is there any sbcs that can run on 3.7v 18650s with similar performance/efficiency to semi-modern smartphone chips?

Edit: is the most cost effective way to get something like this just to buy another Odin 2 and rip out the sbc inside?
