New Acer Nitro 5 AN 515-57 laptop has up to 1-5% CPU throttling in stress tests. Is it normal?

Hippocrat

I have bought a new Acer laptop a couple of days ago, model AN 515-57 (i5-11400H/16 Gb/RTX 3050/SSD 512). I stress-tested my laptop in Aida64 software, and it turned out that at 100% usage of CPU and GPU at the same time, CPU starts throttling up to 3-4%, the temperature of the cores reach 85-90 degrees:

If I load only CPU at 100% (without GPU), then situation looks better - the temperatures are about 70 degrees, no throttling:

Is 1-4% throttling at 100% CPU+GPU usage normal for this laptop? Considering that I bought it just a couple of days ago. Shouldn't the cooling system be designed to prevent throttling even at 100% usage? Are there any ways to prevent throttling without turning off turbo boost?

The i5-11400H//RTX 3050 combo is weakened by the RTX3050 GPU, that is why your CPU is throttling as the NVIDIA GeForce RTX 3050 is too weak for Intel Core i5-11400H on 1920 × 1080 pixels screen resolution for General Tasks and the Bottleneck calculation for Intel Core i5-11400H and NVIDIA GeForce RTX 3050 with screen resolution of 1920 × 1080 (FHD (1080p)) pixels for General Tasks. is 13.4% GPU bottleneck, which means that by decreasing resolution to 1360 × 768 (HD) will give you a 4.9% GPU bottleneck, while at 1680 × 1050 (WSXGA+) it will reduce it to 10.5%. The lower the resolution from 1920 × 1080 (FHD (1080p)) pixels the lower the throttling will be on your CPU.

Thanks for the answer, Steven! But resolutions below 1080p aren't used today... I'd like to know what I should do with this new laptop?
- Use it as it is, not caring about throttling? Then isn't there any harm to the CPU if I will run apps and games which load it at 70-80% (so the 1-5% throttling can be expected right now, and as time passes, it can increase)?
- Or try to avoid throttling? According to your answer I asume that the only way to avoid it is to disable Turbo boost mode? But then the max frequencies will drop from 4-4.5 GHz to 2.6 GHz. It's a huge downgrade… No other options?
