iGPU or dGPU noisier?

Hi all!

 

I was wondering if anyone knows whether the integrated graphics or dedicated graphics produce more noise (due, I'm sure, to heat and the resulting fan noise--though there might be another reason?) when operating under load?

 

The reason is this: I have a program that will run on either the Intel HD Graphics 530 or the nVIDIA Quadro M2000M.  I also want my machine to be quiet so that I don't disturb others.  

My research indicates that the iGPU can run it, though the dGPU can (obviously) handle it far better than the iGPU.

 

Will the added heat from the iGPU crank the processor fan up to where it produces more noise than the combo of the processor fan at a lower setting+the GPU fan on lowish would?

 

Thoughts?  

 

Thanks!

Re: iGPU or dGPU noisier?

You can check this with GPU-Z:

- Get some data points (use your software with iGPU and dGPU and check % load, temperature and noise - on/off or low/med/high - and plot noise vs time or noise vs load, etc

 

- You should see the xGPU behavior vs load, temperature, etc

 

- You'll get two curves; if they overlap, it means there's no difference between the GPU's; if there's a gap, it means they're different (noisier, hotter, etc)
