Razer 15 - 3080 TI or Macbook Pro M1 Max

I have some short animations to render locally for a client think 45 frame clips - and am looking at upgrading an old Macbook Pro 16" 2019 - 8GB 5500M with a Razer 15 2022 or newer M1…

Does anyone know how a 3080 TI Laptop with 16GB VRAM would perform rendering at roughly 250 samples - scene consists of very dense CAD models - I exported one to FBX and it was around 38 million polys and using 1.8gb of textures! Keyshot file is around 1gb itself…

Same question for the M1 using only CPU rendering… :\
