Laptop very slow for playing games with 12gb ram?

Hello i have a 6gb pc which i recently upgraded to 12 but it hasnt really sped up.
I play minecraft you may have heard of with 80 mods. I allocated 4gb to it. Sometimes ill be lucky and get 40-70 fps with settings for high fps then it just drops to 1 fps.People on a server i play minecraft with say that they have lower pc specs than i do and they get constant 80 fps Which i will list here.

Processor: AMD A10-5757M APU with Radeon(tm) HD graphics 2.50GHZ

ram: 12.0 gb 11.4 gb usable

system type: 64-bit Operating system, x64-based processor

running windows 10

And if i have to buy some new part i cant do that because my dad wouldnt let me and i cant really afford anything above $200.

Thanks if you can help!
