Topic: Svp ramps up CPU frequency to 100% but utilezes a lot less.

I have a decent quad core laptop with hyper threading and invidia gpu and while watching videos with SVP all my cores goes to max frequency but utilization is less than 50% so my laptop becomes kinda like frying pan on my lap. To counter it i change my core frequencies similar to utilization percent.

So my question is it possible set like fixed frequency for SVP or tweak any setting to match core frequency with utilization?

i use madVR and GPU acceleration with nvidia gpu and have no playback problems.

Hyperthreading is Intel's implementation of SMT which by definition means that you have two threads per core so as to use up any underutilized resouces, therefore it's rare to see something max out all of your threads.  This is why you would see 50% - your physical cores are being highly utilized but the secondary thread per core is only being utilized a bit.

That's also possibly why your laptop is like a frying pan - you're pretty much running at full tilt considering that you also have a discrete GPU that is being utilized by MadVR.


You wouldn't also happen to have one of those laptops that have no intake vents, would you?  If it's out of warranty, there's a couple things you could do to cool it down...

The thing is if i under clock cpu with intel tuning utility it will still work perfectly fine and that helps me drop the temperature of cpu. So my temps drop from 90 to 65. Maybe my settings are bad.

Of course underclocking will lower the temperature.  If you underclock a 2GHz CPU to 1GHz and then run the CPU at 100% utilization, you would have the same power consumption as if you ran at 2GHz with 50% utilization.

However, lower clocks can also run at lower voltage as well, which will drop your temperate and power consumption considerably more than only underclocking would do - this is why undervolting is even a thing.


Outside of the temperature problem*, I still do not see what the issue is here.



*which is why I asked if your laptop is still in warranty, because if it's not you can do some things about it
