Denoise dreadful, must go back to capture one, far better

Denoise dreadful on new computer, I bought a new Asus duo I9 ultra with 2tb hard drive 32gb ram arc graphics last year and I find that the denoise works twice as fast on my old Lenovo I7 512 gb hard drive 8gb ram Iris xe graphics.

I used to have Capture one that is brilliant on my new computer, really quick, will be going bac to that when my subscription to adobe finishes.
