Daul GPUs ?

[joe_0140]

Is there any logic to using dedicated graphics card for photoshop and intergrated graphics for the display?

Windows 11, Intel i7 - 14700, 32 GB memory

Intefgrated Intel UHD 770 graphics

32" 4K display

Latest Photoshop 2025 installed

No gaming - ever.

Everything performs to my satisfaction except denoise for lg RAW files runs 7 to 10 minutes.  I'm about to install an RTX 3050 6MB dedicated card.  Just wondering... can I configure the dedicated card for photoshop and keep my display on the integrated card?  Only thinking of doing this to allow all resources of the dedicated card to go to photoshop while the 4K display would be handled by the integrated GPU.  Not sure if this has any merit, if performance gains would be meaningful, of if other complications might arise.  Expertise appreciated.  Joe W.

It would be nice if you could separate the pathways like this, but unfortunately that's not how it works. In reality, two GPUs will only cause conflicts - they do that all the time in laptops where this configuration is common.

But there's no reason to use the integrated GPU at all. An RTX will handle all of this without any problems.

I'm assuming this is a desktop machine? Then this is really simple. Just install the RTX into the motherboard PCIe slot, and connect your display to the back connector on the GPU itself. Don't use the connector on the motherboard back panel. Then the RTX runs everything and the integrated GPU is out of the equation.

Thank you for the quick reply. Yes, it is a desktop. I think I’ll keep things simple and just use the dedicated card. Thanks again.

There is a very short description of multiple GPUs with Photoshop in the GPU FAQ, but it basically says that Photoshop only uses one.

It also goes into detail about how to completely disable the integrated GPU when necessary. That's basically only applicable with laptops where the screen is hardwired to the motherboard, and the GPU configuration set by the laptop manufacturer, inaccessible to the user. On a desktop it's not an issue.

Yes, I had already read that FAQ post. I was not actually trying to utilize two GPUs for Photoshop but 1 for Photoshop and 1 for display. My reasoning was that since the RTX 3050 has only 6 GB on memory, I thought that perhaps allowing the integrated GPU to handle display functions it would free up dedicated GPU memory for Photoshop. I had seen posts about configuring iGPU in Bios for dual cards. I saw other posts where a user, for some reason, wanted to use dedicated card for Photoshop and integrated card for Adobe Premier. Anyway, no need to complicate things – I’ll just use the dedicated card for everything. Thanks.
