yes, it can “run ue4”, you will be able to create a project, open it and run it perfectly, but have in mind that the performance that UE4 demands is proportional to the complexity of your project, so as i said, simple projects, like a casual mobile game, or create basic projects and follow some tutorials, then it will be ok, bigger projects, like VR projects or open world projects, will not be OK, i can’t tell you exactly where’s the thin line between “ok” and “not ok” for your project, you will kinda have to discover it by yourself. Also have in mind that better CPU = less time compiling shaders or building lighting, if you don’t mind waiting, then it will be ok.
