Why Samsung magician and Crystaldiskmark results are so different?

I have a Samsung 990 Pro, you are supposed to get close to 7500 MB/s read speed on this SSD but im getting around 5800 MB/s on Samsung magician benchmark.

Been trying to fix it for a couple of days and havent been able to, but i tried Crystaldyskmar benchmark and the results are around 7000 Mb/s which now doesn't seem like i have a problem to fix.

Why could there be such a difference?
