Laptop Throttling

Phantomcorgi94 · May 24, 2022

Hi all,

I have a Dell Inspiron 14 5415, with a Ryzen 7 5700U. As I attempt to use both the GPU and CPU at the same time both only go to about 50% utilization. According to HWinfo64 my laptop is power throttled with its included 65w power adapter. If I buy the upgraded 130w edition of the charger will I get better performance of the GPU and CPU. I tried contacting dell, they kept telling me to update the drivers and that will fix the error. I tried telling them that I was only interested in knowing if I would get better performance but had no success,

Please Help me

go into the settings and make sure its not on power saving mode or anything, if that doesnt work go into services and disable the "power" service to force off all windows throttling features.

if that doesnt work it may be something in the bios.

edit: i misread the question, i thought you said "i will get better performance" instead of "will i get better performance", sorry.

no it will not affect performance.

The 5700U is (generally) a 15W chip in this case yours is a 15W, the entire chip is going to be pulling 15W, so a 130W charger is not likely to give any difference over the 65W charger that it comes with, 15W is 15W no matter how much power is supplied. The 5700U is also not overclockable so the performance you have is most likely a thermal limit, according to Dell the panel is <5W and the 5700U is 15W max, so the system is probably pulling at max 35W total at 100% CPU+GPU load full brightness.

At best, the 100W charger would allow it to charge more quickly if it allowed 100W of input.

In regards to the drivers, it would be a good idea to update drivers and see if performance changes at all.

so what does this mean when it says that the cpu is pulling 25 and the gpu is pulling 24-25

also is my laptop any good?

Can you run Cinebench R23 (to maximize the CPU) and Furmark or 3D Firestrike (to maximize GPU)?

Then check, how much Watt the whole "CPU Package" draws, including CPU + GPU + other things that are part of the CPU Package.

Each of these Benchmarks should get the CPU or GPU to 100% usage.

If that stays well below 60 Watt, you will most likely not not get any different Performance.

In Fact, i believe, the Power Adapter has nothing to say here. Your Chip draws as much power, as it is allowed to. Based on Temperatures, Watt TDP, Powerstates, etc.

If it were to draw more Power than your Power adapter can provice, it should simply take the needed rest from the Battery, which will cause your battery to go empty despite beeing plugged in.

In your Screenshot, Throttle Reason is "Power". I think, this isn't because of your Power Adapter.

But a CPU can only draw xx Watt as a maximum. Whatever AMD / Dell configured into the Firmware/Bios. It will never go above that.

If they say, the CPU Package can not go above 50W, then it won't. No matter what.
