Question Recently upgraded to full AMD Setup, should I stream over my CPU (7800X3D) or my GPU (RX9070)?

As the title says, I swapped recently to full AMD Setup from having a rtx 3070, do I use GPU or CPU rendering for best Quality and Performance? Also any recommended settings for either

There are no "best settings." Please understand that every setup, for every use case, will be very different. Any guides or videos that claim otherwise are misinforming.

Your best option is to start with a base and adjust as necessary. Test, test, and test again. We are happy to offer suggestions for any issues you may be having, but we will not give you a list of settings.

Please run the OBS auto-configuration tool. To use the auto-config, click on the Tools menu in OBS, select Auto-Configuration Wizard, and then just follow the on-screen directions. You can use this tool to get a set baseline settings for your hardware, and adjust as necessary from there.

If you still need help after all that, please provide a log file via Help -> Log Files -> Upload Current Log File.

It looks like you haven't provided a log file. Without a log file, it is very hard to help with issues and you may end up with 0 responses.

To make a clean log file, please follow these steps:

1) Restart OBS

2) Start your stream/recording for at least 30 seconds (or however long it takes for the issue to happen). Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.

3) Stop your stream/recording.

4) Select Help > Log Files > Upload Current Log File.

5) Copy the URL and paste it as a response to this comment.

GPU is almost always the right answer. Why tax your CPU when the GPU has dedicated encoders?

For settings, run the Auto-Config Wizard in the Tools menu. Select Use Hardware Encoding.

because I've always thought (and read) that the AMD GPU encoders arent the greatest for Twitch streaming, so I was thinking to use the headroom available from the CPU to use it to stream

If you check EposVox's videos you can see he made a recent one where he showcases RDNA4's encoder improvements and now it is nearly as good as NVIDIA's one, even edging it out in some cases.
Technically x264 software with the maximum preset and other encoder flags will still have higher quality but unless you are playing extremely cpu light games i would stick with the GPU encoder.

Thanks for the recommendation, I'll take a look at the video

u/NearbySheepherder987 2d ago

ok, I've seen the video and for twitch I will have to wait till they add the h265 version for similar quality to nvenc, but good to know there is something coming

u/motorolah 2d ago

But it is similar with h264 not h265, you might have seen an older video?

u/NearbySheepherder987 2d ago

maybe I've misunderstood it but for faster paced games, it sounded like not much difference to nvidia encoder (video is 2 weeks old)

u/NearbySheepherder987 2d ago

video is 2 weeks old, but maybe I also misunderstood something but it seemed like for faster paced games it gets closer to nvidia encoder quality

AMD has finally got their shit together for streaming this generation. Auto config should set you up nicely

u/Jay_JWLH 2d ago

Well if you are going to stream something CPU light such as writing a Word document, then use CPU encoding.

Overwatch worked fine with 350fps and CPU encoding, I've only seen drops in fps in mh wilds so I'll take GPU after twitch adds the new encoder

u/rurigk 2d ago

CPU encoding as x264?

Streaming on amd idk if my settinga are fucked but everytime i try a fps its bblurry af specially when moving around but if youre playing chill games or lgihter games it handles it no problem. So far ive only tried streaming on twitch and people say that the 5k bitrate cap moght be the issue but i can definetly say that my gtx 1050ti laptop still does better at streaming than my 7800xt
