The gpu on this chip is very low end, it's a mali G52 mp1 2EE, around 27 Gflops, so, even worse than videocore 6. But the real performance inside of x11 its quite consistent with rpi4 gpu performance.
I hope the rk3566 is power efficient and quite powerull.... it could the make it i to a pinephone. Pinephone is desperate for a SOC that would make it worth a daily driver ...
