Question / Help 8350 Black edition 4.0 GHZ and x264 preset - Slower then Faster?

[Denkimon]

Hello! i've been reading so many comments and posts about how good the 8350 really is.


I've read people saying it does 1080p 60fps "just fine" which i highly doubt since it wont do 720p 60fps at Fast with twitchs restricted bitrate it definately makes a change toying with the x264 commands / changing presets.



I'm using a dedicated streaming PC with the specs listed here

Processor: AMD FX 8350 Black edition @ 4.0 GHZ
Graphics Card: Sapphire 7970 Vapor-X 3gig
Motherboard: Asus M5A97 LE 2.0
Memory: 8 (1 x 8GB) DDR4 2400 MHz
Capture card: Avermedia Liver gamer HD C985
OS: Windows 10 Professional 64 bit

I found a thread where some guy said it's about as good as the 3770k which i think he/she have no proof of since i got both these processors and i can record at Medium preset whilst playing and having tons of applications running on my gaming rig.


To sum up: Anyone have any good idea of how i can push extra quality out of my processor or is it simply to just be happy with the quality i have at Faster (with a few custom x264 commands) ?

thats sadly a really old post and quite a bit changed.

for nowadays comparison you set the fx8320 equal with last gen i5 for raw encoding performance.

as a streaming machine they should be able to handle 720p60 on fast but as a gaming + streaming machine they max out usually at aroun 720p60 veryfast on not cpu demanding games.

Well... if you're talking about recording-only, lots of processors can go at 1080@60fps, so long as you use Ultrafast and throw a mountain of bitrate at them to compensate.

Livestreaming purposes, no, the 8350 is not going to be able to run 1080@60 Veryfast. Not even close. Even a stripped-down i7-4930k is going to have problems. A 5820k can swing it down to Medium.

AMD isn't comparable to Intel as far as livestreaming goes; the time Intel spent refining and optimizing their core design while AMD just strapped more of the existing ones on is really showing at this point. There's a reason many get in on AMD due to the lower price point, and then switch over to Intel down the road. For just gaming, AMD is absolutely a viable option. But it falls apart when the load of real-time video encoding is thrown into the mix. No fanboyism, I have AMD machines as well, for purposes that don't *need* the expensive parts.

Yeah okay, thanks guys for the clarification. i bought the 8350 from a friend for a cheap price of like 100 euro so i thought id turn it into a streaming PC since i've heard / read so many good reviews and that it's capable of streaming & rendering very well but got a bit sad when i realised i cant really push the harder presets.

Also since i see you FerretBomb is using the Micomsoft SC-512N1-L/DVI whats your opinion on it? I think i'm going to order one when the next Intel CPU generation hits the market and turn my 3770k rig into my streaming pc.

Anyway thanks for the answers!

If mine broke, I'd be ordering a new one within 5 minutes. It's a great card, even at the $330 price point for the Micomsoft version (and if you can get the $200 Yuan SC512 version, even better; just use splitters as it doesn't come with the passthrough daughterboard).
The only other one I'm considering is the Magewell 1-channel, as I've heard good things, and it does almost as many input types as the SC512.

When doing a 2PC setup, you want the one with the beefier CPU as the encoding machine. Otherwise it's kind of pointless, and adds a lot of hassle (especially with audio setup) for no good reason, whereas the other way around you can crank things up to 11 on the encoding machine, and get by with a weaker CPU on the gaming machine due to how much lower-demand gaming is on a CPU as compared to the load of real-time video encoding. Kinda why I don't use my i7-920 as an encoder... it can't hold a candle to the 5820k. But I might consider gaming on the 920 and running barebones on the 5820 to see what kind of preset I could run, at the extremes.
Especially so with the decacore i7-6950x coming out Q2 2016... considering upgrading to that, but there's almost no point when I can game and stream on the 5820k as-is at 1080@60 using a Medium preset.

For a 2PC setup you want a lot of cores. Once you go past 4 cores, then clockspeed is less important. Single core IPC x clock is what you want for gaming, but for encoding, its IPC x clock x cores, and if you can add more cores cheaply, the clockspeed doesn't matter so much. This means that your AMD might surprise you positively as a dedicated encoding PC, but from everything I've read it still isn't good enough to do 1080p60 at a good preset.

This is why I'm interested in the current Ebay glut of E5-2670 (Sandy Bridge) Xeons... decent thread on it here: http://forums.anandtech.com/showthread.php?t=2464901

The potential is there to build a bad-ass streaming PC for relatively cheap. Gotta get an expensive motherboard and full tower case, but its still cheaper than a Haswell or Skylake i7 and its motherboard, and significantly higher performing to boot. It won't be great for gaming because the clockspeed is only 2.6 boosting to 3.3, and the IPC is only at Sandy Bridge levels. But for a dedicated encoding PC, its pretty awesome.

And I've ordered my parts, motherboard is the last part I don't have and its arriving today. Excited!
