No, each core would be weaker compared to a consumer grade CPU like i7. But it would wipe the floor with i7 when doing multitasking. So it's a no when using it for core limited things like gaming.Do you want 32 cores?
For games, more than 6 cores are not needed. 4 for the game, 2 for windows + streaming + etc. The 4 might change to 6 with new game engines optimization and better DX12/Vulkan support.But do you really need them? Well, that depends.
You sure you did your calculations correctly? Blender doesn't agree. R5 1600 is 1.65x (40%) faster than 8350k.The i3-8350k at stock is barely 10% behind the 6c/12t 1600 when looking at a wide variety of different workloads,including all kinds from heavily multithreaded to medium and lightly ones.
