GPU doesnt boost

[NeoRO]

Hi.

I've recently got this great deal on a laptop.It's an HP 15-db0050nq laptop with a Ryzen 5 2500u and Vega 8 iGPU.I use it mostly for school work and some esports games, but i've noticed something.I ran Unigine Valley and noticed the iGPU only boosts to about 900mhz,and then suddenly drops to 400-500mhz.The max temperature is about 70 degrees C, but the frequency doesnt drop when the temperature hits the max, it goes down after quite a lot of time after that, at which time temperature is about 65-68 C.

power limits. normal for laptops

I know they're normal in laptops, but shouldn't it at least reach it's max core clock before it hits power limit?

Nope

Let's say it's power limit that restricts it from hitting it's full 1100mhz clock, but it isn't even maintaining 900mhz.It goes all the way down to 400-500mhz , which is it's base clock, and it keeps running at that frequency,It won't go back to 900mhz.Only way to get it up there again is to stop the app and launch it again.

It's how PL1 and PL2 work. Your laptop is configured for cTDP down - meaning it only has 10W for the CPU AND iGPU - so the iGPU has to use 4W or so of power to maintain performance. Blame HP for not designing a better cooling and power delivery system

Wow.That's a really stupid design.Even worse than apple.

Well it's a media notebook, not a gaming laptop

I understand, but it's not like this APU is some kind of powerhouse.It's designed to use 15w when both CPU and GPU are running max clocks.This notebook's power delivery and cooling can't even hadle that.

It's designed to use 15W. Max clocks listed on box are for cTDP up which is 25W

Can it help if I undervolt?
