Is there a point of NVMe drive with speed 14700/13400 MB/s over 7450/6900 MB/s?

The Samsung 2TB 9100 PRO SSD, PCIe 5.0 x4, NVMe 2.0, 14700/13400 MB/s has about double the writing and reading speeds (atleast on theory) over Samsung 2TB 990 PRO, PCIe 4.0 NVMe M.2 SSD, 7450/6900 MB/s.

Does anybody have any idea about how much does this "double speed" affect the system speed and loading of programs/games in general?
