while more cores is better, it has to be utilized fully to harness that power. tasks like video rendering and 7 zip compression can use all ur cores. but games now mostly use only 2 cores. dx12 and vulkan with new game engines can change that.
so if gaming is ur primary task, that amd a series apu has lower compute power per core than intel's i5 and i7. they also overheat and hold back the otherwise very good gpu. my old laptop is a a10 7300 with r7 graphics. amazing graphics with subpar cpu.
