Best Intel Processor for Twinmotion

Needing to get a new laptop for Twinmotion and other 3d use. Currently using Intel-i9750-H and RTX2070 graphics card and 32gb RAM. Should I really expect a noticeable difference in video processing time and path tracing processing times with an i-14900HX Processor, RTX4080 Graphics Card, and 64gb of RAM. Anybody have any experience with similar upgrade? I would hate to find out after spending $$$ on a new system that nothing really improves.
Replies gratefully appreciated.
