@zygoon LicheePi 4A uses TH1520 CPU (4 cores @1,9Ghz, 4/8/16GB RAM + integrated eMMC storage, Vector 0.7.1 spec support, NPU, is currently mainly on kernel 5.10).
It is (now) "Not great, not terrible". With new kernels coming (6.5-6.8) and thus drivers (OpenGL/hw accel/AES accel etc..) and other things coming later this year, it will become quite ok as light desktop/light home server backend.
