Question / Help CPU capable of SLOW preset?

Wondering if any of you have an experience or know of a CPU that would be able to be able to run a SLOW preset if it were in a streaming PC in a 2-pc setup.
 
properly have to be at least a 6 core... properly the i7 extreme 8core.. however.. the difference between slow and veryfast preset.. is that not much in terms of quality...
 
I have an i7 5820k @ 4.4 Ghz, I can run 720p @ 30 FPS with slow preset and 720p @ 60 fps with medium preset. I think you'd need an i7 5960x at least to run slow preset at 720p @ 60 fps. Difference between veryfast and fast preset is pretty big in my opinion, but anything after that, almost null.
 
i clearly see some misinformation above... my amd fx-8core @ 4.7ghz can run 864p60 @ fast ... and almost medium when on it's own without a game running on it ... 5820k@4.4? - should be some 60-70% stronger or so.

Well...I can run 864@60 fps with medium preset with only 70 percent cpu usage (in battlefield 4, which is a very cpu intensive game)...its just that the jump from the medium to slow preset is very big. on 720p@ 30 fps , the difference in load between medium and slow preset for me was almost 60 percent.
 
well - i just upgraded to a 5820k myself ... mine can even run 4.6ghz on air @ 1.29volts ... the settings it can pull off are a pretty decent step-up from the amd - HOWEVER .. ive been making some sample videos and im slowly getting an impression the AMD somehow rendered a slightly higher quality image when using the same setting and bitrate ... how is this possible? - anyone heard anything like this? i will need to make alot more samples i guess and post them somwhere to make sure this is not somekind of placebo... maybe the amd architecture is somehow better optimised with OBS?
 
Yep, that's all in your head. It's the same encoder, and will produce the same picture. AMD is inferior for real-time encoding, flat-out, at equitable chip levels.

Far as the OP was asking, depends on what resolution/framerate you want to run Slow on. I doubt even Frag's 2x10-core Xeon rig is capable of 1080p@60 on Slow, for example.
 
well its how it should be but i will still look more into it - remember - different amount of threads are being used by obs etc. - maybe something gets affected because of it. And don't discount AMD yet - i compared my 8370e@4.7 to a stock clocked 4790k and it was barely any better not more than some 5-10% difference, also try streaming assassin's creed unity - i managed to seperate the game and obs on 4 seperate threads each and somehow got a smoother stream out of it this way than going with 6 and 6 threads on this new intel (altho game fps and possible stream settings are better here of course) - the Game capture stuttered less on AMD and the video came out smoother. with intel i have to limit the game fps to 30 using DXtory or force the game to run 1440p ultra to get a smooth-ish 30fps stream out of it - so since i have used both AMD and Intel for streaming with various settings i think my opinion counts :)
Edit: monitor capture works alot smoother than game capture tho, i jsut sense some differences in image quality as well

Yes, I'm sure if you overclock an AMD chip, you may be able to keep up with an i7 at stock speeds. :b AMD uses more, higher-clocked, lower-quality cores (and fake cores) which result in peaky performance; something you don't want in a real-time production environment.

Sounds like your system has other problems that really need to be addressed, if your game capture is coming back juddery.

'Sensing' doesn't count. Leaves it open to bias. If there's a difference with the video, it's because of your setup or an underlying problem. :b
 
x264 - integer operations - so it works well with amd's architecture ... why do you think they beat the i5's in video encoding programs... and who doesnt overclock a FX chip lol... its a dream with them + the E versions get less hot than the intel's .. mine was sitting below 60c on air @ 4.7ghz ... prime95 produced up to some 61-62c
also try streaming Unity on ultra before you judge - you will see the same thing - the game simply uses alot of resources on your PC - game capture with it stutters. seen other streams with the same problem.
p.s. look at this game's section on twitch - nothing but consoles! people probably can't stream it well with their pc's
here's how it runs on my 5820k@4.5ghz 720p_30fps_slow when game is forced to 30fps http://www.twitch.tv/venturfear/v/13714511
i did look at the logs -

11:22:45: Total frames encoded: 19894, total frames duplicated: 82 (0.41%)
11:22:45: Total frames rendered: 19879, number of late frames: 8 (0.04%) (it's okay for some frames to be late)

Integer operations work well regardless of AMD/Intel. Again, AMD provides peaky performance. Not an issue and can be quicker in non-realtime video encoding, but the peaks and dips make them unsuitable for a real-time, production environment. There's a reason serious streamers use Intel based rigs. Newbies get in with AMD, thanks to the lower price.

'Everyone overclocks it'? No. You compare apples to apples. An i7 with a proper overclock will see further gains, due to already higher efficiency cores. AMD starts out chucking more cores and clockspeed at a problem in the first place. Pushing it higher will extend that performance, but to get past the top of that short hill, you need a more efficient core. Which AMD hasn't bothered overhauling for a while now, as they're focused less on top-tier performance, and more on the budget-minded consumer.

Yep, Unity is pretty well known for being a poorly-coded game... almost on the levels of BF4, ArmA III, or Arkham Knight.
 
Well you are mostly right there - im not arguing at all, just at the price point where you can right now buy a fx-8320e for some 120eur and a 4690k ~ 210eur / 6600k ~ 250eur ... yet it sits between the i5's and the i7's when streaming ... its still awesome!
battlefield4 by the way doesnt come close to the cpu usage of unity when streaming, altho until it came out i considered bf the toughest one! - to give you a comparison BF4 64player didnt have any issues streaming 720p30 fast with the amd ...
while unity couldnt even really handle 616p .. high encoding messages from time to time ... only when i separated the game and obs on seperate threads i got a stable 720p30 fast out of it but the game fps dropped considerably due to using only 4 threads...
