My laptop processor is not hitting advertised max boost clock.

[~Secret.Cur3~]

The laptop is an Asus tuf fx505du, running on Ryzen 7 3750H with Radeon Vega 10 integrated gaphics. But for games Nividia gtx 1660ti is the driver but i suppose thats irrelavent.
And just to be clear the cpu is not of the Ryzen 3000 series, or Zen 2, which was released recently. My CPU is based on Zen+ Architecture which was released last year.
I ran cinebench R20.060 with the laptop on turbo mode yet the max turbo boost id hit is 3.61Ghz which is pretty much 400mhz short of the advertised boost clock of ryzen 3750H.
Does this happen to every laptop or do I need to asus contact customer support?

Zen2 has had issues with clocks since launch, and it's based completely on load. Just running CB R20 isn't going to push it to the max as it's not the type of load that would hammer it to that degree.

4Ghz is the max boost speed, the CPU will only reach this clock speed during single (and sometimes dual) core workloads.

3.6Ghz is the highest all core boost speed.

This CPU is Zen+, not Zen 2.

Disable cool & quiet in bios and put os power profile on high performance. Set nvidia gpu as the default in Nvidia control panel. Also under there, set power management to prefer max performance, set threaded optimization to on

Disabling Cool & Quiet and setting Windows to high performance will both do the same thing. So no point in doing both.

And I recommend against doing this on a laptop which really needs these moments of lower CPU usage to cool down.

AMD is already working on a fix to solve the issue with RyZEN 2 CPUs not boosting properly.
An update already leaked, so it should arrive sooner rather than later.

I do not recommend using the leaked version as it may have issues that still need fixing.

This is not a Zen 2 CPU so this does not apply here.

Cool and Quiet causes the clocks to change, even in a game during periods of cpu load changes, this can cause sparatic in game stuttering.

Putting Windows on high performance doesn't exactly change this.

Even with it off though, the cpu should still cool down still fairly rapidly when the cpu load is idle or much lower compared to very high.

Make a program that consists entirely of noop instructions and you can hit advertised clocks on Zen 2.

It's not Zen2, it's Zen+. You'd think it is, but it isn't, because AMD's Ryzen APUs and Mobile chips are one architecture behind.
