My new CPU is the same performance as my old one?

I got my new CPU (AMD fx 8350) for minecraft. I heard minecraft is a CPU based game. My old CPU was a AMD fx 4130. I've seem the same amount of FPS from both CPUs I don't understand. Pretty much I get 150-200 fps on minecraft from my old CPU. Now I get 150-200 fps still. The CPU is a whole lot better than my old one but it doesn't increase the speed.

Usually in games the GPU makes the difference.

I suggest getting the mod optifine because the fx 8350 is a eight core processor but minecraft will only uses one or two cores. This mod optimises it so you can have multi core rendering taking advantage of your processor to get more frames per second. Ps I also have a fx 8350 and recommend upgrading to windows 10 for direct x 12. It uses multi core processors much more efficiently than dx 11.2 resulting in better frame rate. Well I hope this helps
