I tested using the default settings of radeon pro render for blender with some exception of some settings like the number of samples that i changed to 128 istead of 64 in all tests and samples updates per view in some tests
so lets begin
test 1= cpu+gpu/samples per view update:4 = total time 01m.11s.19ms
test 2= cpu+gpu/samples per view update:64 = total time 04m.26s.07ms
test 3= gpu only /samples per view update:4 = total time 00m.18s.58ms
test 4= gpu only/samples per view update:64 = total time 00m.16s.09ms
