The RVA23 spec has only just been ratified a couple of weeks ago. It will be a couple of years before there is hardware supporting it.
A suitable RVA22+V chip (SpacemiT 8 core) has only been out on dedicated dev boards for a few months. That's probably going to be their 2025Q2 main board.
Their 2025Q4 main board will be the first high performance RVA22+V one. If the chip happens ... it's struck some political (sanctions) problems.
JH7110 is the right chip for a first board to get the wrinkles ironed out. No one has ever done a 3rd party or non-x86 mainboard for Frame laptops before.
