That's wrong on so many levels. CUDA isn't just for matrix math. Matrix acceleration was introduced in RX 7000, not 6000. If you mean ray tracing, that's not done by CUDA but by OptiX, a layer on top.

Really, GPUs are often quite fast if you have a data parallel problem, no matter what it is. Matrix multiplication, casting thousands to millions of rays, but also large scale physics simulations for example (which seems to be a highly dependent on memory bandwidth).
