I have a Asus X670e Hero motherboard and a AMD 7950X3D… with a TUF 4090 .

Now is the IGPU and use if using the 4090… can it be used for anything at is it best to disable it in bios… or install drivers for it and just leave it be ? 

San having the IGPU drivers install cause any conflicts ?

Any help most appreciated…

Hello,


Beyond driving different screens there's no real benefit, but there is usually no harm in leaving it enabled.

Ok 👌 thanks you… prob just re enable it in bios and install drivers just incase lol 😆.

Just thought 💭 I read something in past that the igpu could help with video encoding or something like that ..but I may be wrong lol 

Cheers 🍻 

No worries. Are you doing video encoding?

I do a lot of videos using AV1

I run a 7900X3D with a RTX3070, and the iGPU is way faster at encoding than the NVIDIA.
Probably because the PCI is bottlenecked by my M2.

Ive not installed drivers for the igpu… is it worth it ?

Only if you do a lot of video-encoding, game capture, or broadcasting.

I do a lot if vr recording with obs… using av1… how do you utilize the igpu for this ?

I never used OBS before, so I did a test: https://youtu.be/L9Teu0GRfD4
Only difference I'd notice when recording h264 was a little more compression artifacts (blocks) when recording with the NVENC than the AMD. Recording HEVC was lagging on AMD  but not so much on NVENC. Benchmark results was 500 points higher when recording on the iGPU.

(Didn't have support for AV1)
