I'm planning on getting a 2nd PC for streaming and I was wondering if it's better to get a processor with higher cores or a higher clock speed. How much do multiple threads help with encoding? Is it better to get a processor that is duo-core with a high clock speed, or a quad-core with a medium clock speed

Im not an expert, it probably depends on particular models. But from my experience streaming 3 HD webcams on Phenom II B97 in HD, very fast setup gives all 4 cores set on 85-95% all the time. So basicly 4 cores setup is minimum, you dont want to go 2 cores even if they are very strong.

I dont believe that. I using a dual system. In my streaming pc is an i7 4790k oc 4,4GHz and with a capturecard like elgato hd60 pro and webcam (set to 720p60fps) use i reach still in 1080p60fps veryfast settings almost the max cpu usage to stream. I dont know how other capturecards works. But this is one of a few capturecards which could output 1080p in 60fps. Before i used an i7 2600k oc to 4,1GHz and this cpu cant be used for this settings i just say before. Because of to high cpu usage

that's strange because I use a i7 4790k @ 4GHz on my gaming pc and when I play csgo while running OBS I dont get that close to 100% on 1080p 60 fps 3k bitrate

Capturcard use a higher cpu usage in obs than normal gamecapture or screen capture. I Still test different things and the capturecard is just using the most part of your cpu usage in obs. Dont ask me why probably a capturecards and obs doesnt work so good together like normal gamecapture. Maybe in any feature time that will be get a change from both sides

what settings were you able to stream on with your i7 2600k

720p60fps. If i remember right, if it was verfast or faster cpu preset with 3000kbit/s upload speed. But the cpu was oc to 4,1GHz just to let you know. I could also not remember if i use in this time 1 or 2 webcams in my stream. So cpu usage could be different a bit. Most of the time i reached around 60% cpu usage in my streaming pc, while playing on my gaming pc ingame anything

60% usage is not bad, was that the average or the highest it would go? This would probably work really good for me if im trying to start off streaming anyways since viewers cant downscale quality

Average . It was moving around 50-80 % but the system only use the cpu for obs/webcam and capturecard. While i was gaming on my second pc

But get sure that your stream dont run too on your streaming system. Stop all videos in the background to decrease the cpu usage as much as possible. Every stream you watch cost propably 20% cpu usage
