Yes.

You can even use numpy in nim: https://forum.nim-lang.org/t/4102

But why use that when you can use Cuda and OpenCL accelerated vector math: https://github.com/mratsim/Arraymancer

If thats too much speed, you can just roll your own for loops. Because Nim is compiled with battle tested GCC, LLVM or VC++ it will try to SSE optimize your code if you pass the right switches. If you know what CPU your computer/server has you can compile with newest brand of high performance instructions like AVX2, or even the newest AVX512VNNI...

Because my laptop's GPU is Intel GMA 4500M HD, it neither supports CUDA nor OpenCL.
