Rockchip SoCs RK3566 and RK3568 have a Mali Gondul core
which is based on the Bifrost architecture. It has
one shader core and two execution engines.
Quoting the datasheet:
Mali-G52 1-Core-2EE
* Support 1600Mpix/s fill rate when 800MHz clock frequency
* Support 38.4GLOPs when 800MHz clock frequency
