Turbostat log output

I have a Dell Latitude 5420 laptop and i am experiencing CPU slowdown when
using any graphical / CPU demanding application.

The laptop contains 11th Gen Intel(R) Core(TM) i5-1145G7 which can do 4,4GHz on
turbo.

When the system reaches about 70���C, all cores switch to 400MHz and stay there
until temperature hits 53-54���C.

I can see this behavior especially in Vulkan graphics applications, but not
only in them, it just happens almost instantly there, since the 70���C is reached
within about 30 seconds there.

I would want to raise the temperature limits to at least 80-90���C or disable
throttling completely (at my own responsibility of cooking it). But throttling
from 70���C seems as a complete nonsense to me - the CPU package gets to this
temperature in 10-20 seconds under load, so i basically never make use of the
4,4GHz.

What i have tried:
1) Kernel 5.19 from Kernel:HEAD - no change
2) installed throttled ( https://github.com/erpalma/throttled ) - no change
3) blacklisted intel_powerclamp, intel_rapl_msr, processor_thermal_rapl,
intel_rapl_common kernel modules - no change
4) cpupower frequency-set -g performance - no change
