Question / Help Logitech C930e or C920 for low-medium performance PC?

Hi there, quick question regarding these two webcams.

I've seen that the C930e has onboard h.264 compression which would be nice to save on USB bandwidth, keep DPC latency down and generally save resources for other USB devices.

I'm still on a 2500k, p67 platform so it does choke a bit given I've all of the PCI-E lanes used up, loads of hard drives and quite a few USB devices.
Question is, does the C920 also have this, and can I take advantage of this onboard processing with OBS, with whichever camera supports it?

This issue with any device that does this is one of two things. either loss of some quality or higher latency. an example of this would be the elgato with its 1500ms delay to compress 1080@60 over a USB 2.0 line and try and maintain some quality at the other end.

Not to say this would be the same but understanding there would be at least some latency for encoding and decoding done prior to OBS receiving the picture. Also note that if it is encoded, it will need to be decoded which might mean higher CPU usage in the end.

I am speaking in general as I'm not aware of the C920s ability to encode h264

I don't think there's been any major improvements from P67 to today. The main thing is to not have so much stuff on the same USB channel as your webcam. And to not use too high of a resolution on your webcam. Most problems I see with the C920 is when people try to use it at 1080p, keep it down to 720p or lower and it'll probably be fine. I don't see any logs with the C930e, that I can remember.
