Macbook Pro 2022 M1 vs Windows 10 AMD Ryzen 3900x and RTX 3070, why is macbook faster?

Dear everyone,

I have two machines. A macbook with M1 processor (16GB RAM) and a Windows with AMD Ryzen 3900x and RTX 3070 32GB RAM. The intention always was that the latter was my expensive and faster working workstation... But it turns out this one often lags in previews where the macbook smoothly RAM previews. I am a bit at a loss here... I tried all things possible to make the windows faster, but with the same scene file Macbook wins every race in terms of previewing smoothly. Is this normal? Is something wrong? I definitly am a bit disappointed that my expensive hardware eventually loses to officially slower hardware of the Macbook.

Hope someone can clear this out for me.
