I don't know the answer, however Minecraft is mostly CPU limited title, since it's java based. Therefore your CPU is going to be a much bigger factor in you getting high FPS. Several people last year told me that Minecraft run on Windows 8.1 and above started requiring a discreet graphics card. Matter-of-fact, I just last year gave away my old ATI HD 4670 to a dad on this site, whose daughter simply wanted to play minecraft; that card is 8 years old. Worked out great for them, although I don't know what frames they were getting. What are your full specs?
