Are there external CPUs for laptops?

I work a lot with fl studio (music production) and sometimes my laptop pushes to its limits, is there some kind of external cpu or other ways to improve the performance?

I do not know! I always asked myself! I'll check it out! And I would throw down all the programs I do NOT need (anymore)!

If the program supports it, you can integrate other computers into the arithmetic operation via network. With animation software, the standard in music is not a clue.

If the program does not support it to distribute the computing power on several computers probably only a fixed Pc to buy. The fixed because the same computing power are much cheaper than comparable laptops.

Correct external to connect via cable no, via TeamViewer you could use a powerful PC but you could also use a cloud gaming program
