GPU Performance Scaling

Hey everyone
On my p650SE there is an option in the BIOS for GPU Performance Scaling.

Anyone know what it does exactly?

Thanks

I think it switches scaling from IGP to dGPU under certain circumstances. Just leave it on the default setting.

 

It enables/disables the possibility to overclock the GPU.
Designed for Clevos new GPU OC App (in the folder of the latest HotKey App)

Nope, that's NOT a stock vBIOS.

 

OK now that's interesting.

 

clevo gpu oc app?! dayum....clevo is stepping up their game

edit: there actually seem to be TWO gpuoc tools, v1 and v2, the latter also providing vram control. interesting tidbit: gpu core temp turns from blue to red once it reaches 64C. why that specific temp @Prema?

Wow now that is interesting! Thanks for the info!

 

are you sure? seems this is an option for scaling only, done by dGPU or iGPU. this is present on other laptop brands as well.

Couple of things:

1/ The Eurocom Shark 5 is also a Clevo (N150RD) so it's just the same GPU Performance Scaling option appearing on a number of Clevo BIOS. In fact, it is not limited to Clevo though, it's an GPU and CPU power control - see below

2/ It is a control which allows a mjnor increase or efgects a minkr decrease in graphical performance in Optimus systems where the dGPU is routed through the iGPU buffer for internal laptop displays. This also has a direct effect on the clock speed of the CPU - it doesn't only affect the GPU performance.

GPU Performance Scaling Disabled (default setting) means that the GPU will operate at standard max performance and the CPU should also perform at highest clock speeds limited only by the usual TDP etc limitations

GPU Performace Scaling Enabled means that the GPU will run at a higher performance level i.e. scale higher, but then the CPU runs at lower clock speeds in order to compensate and level out the thermal and power levels of the whole system.

I have purposefully not gone into huge detail with these terms - it is what it is and the setting serves a purpose for some people and not for others ;-) If you have very high demanding GPU apps which wouldn't suffer too much from lower CPU speeds then set to ENABLED. If you want a balance of GPU and CPU power then switch to DISABLED.

Prema is correct to a point, it is related to the Clevo OC tool, but that's not the whole story.

For reference; the Scaling option was first introduced in April 2015 in the W230 and P65 models.

 

This is confusing...

What about the quote form the Clevo service manual that I gave link to earlier ?

GPU Performance Scaling (Advanced Menu > Advanced Chipset Control)
You can enable/disable NVIDIA GPU Performance scaling from this menu. The
NVIDIA Card does the scaling if this option is on, and has less latency than the Intel
GPU. This can be useful if you play games etc.

 

It actually alligns with what the others are saying. It basicially says that the Cards get more juice and gets to do more for games and such. It also makes the dGPU scale the image, which is interesting, meaning DSR should be possible on those systems.

 

I have edited my above post to help make my explanation a little clearer. It is information I have paraphrased from email exchanges with engineers in 2016. The user manual is not wrong, but I concentrated on the effects that enable and disable make to the GPU and CPU performance plus that the function wasn't specifically introduced to support the OC tool bit it does work with it.

 

I personally don't see any difference. The overclocking software works with it enabled or disabled and I don't see any performance, clock speed or voltage differences for GPU or CPU, they always remain at maximum even under heavy load no matter what I set the setting to.
Then again, I don't have Optimus in m U727 2017. Not sure why the BIOS still has the option, though (and it was enabled by default for me, by the way, since others said it was disabled by default).
