Last response: in CPUs
i may or may not have the opportunity to trade in my FX6350 and get a FX8320 in place for not a huge total expense...
interested in streaming and unfortunately my 6350 can't quite keep up with what i want,
(its actually a good streamer for something like 1536x864 @ 45 fps using the standard "veryfast"
or maybe "faster" x264 CPU Preset from OBS when you limit the games fps to 45 too)
but for what i want (real high quality with low-ish bitrate) im afraid even a 4790k wouldn't be enough and maybe a watercooled 5960x should be called to the party.... - at the moment not a drug dealer so yeah...
SO - does anyone have any actual idea what sort of gain the two additional cores would provide me with while streaming?
and what sort of voltages are ppl ACTUALLY running on their 8320 around 4.5 ghz and higher?
and i don't mean idle ... i mean prime95 full load voltages .. you know - with the LLC settings turned up or whatever the case may be ... (this could help me figure out my cooling capacity (CNPS12X)
the 8370/8370e are the tempting ones of course but they scratch intel price territory so its just retarded, and probably are no better anyway...
AND one important thing - how often do we see 8320's that can't oc as high as 8350's etc? is the whole thing about them being the same 99% of the time just that? a myth? or you an really buy one and expect atleast 4.5ghz?
so - FX 8 core vs 4770k/4790k for streaming - does anyone have actual idea how they compare?
because if the diff is huge i will forget about the amd upgrade and focus on some 5820k o.c. project or something in the future...

All 8320s can oc to 8350 speed with a vcore between 1.38-1.44 the two cores will certainly help with streaming I see a lot of people doing 720p and it looks pretty sweet. And they are more than 99% the same chip they are 100% the same chip.it bothers me that my 6350 requires almost 1.5v for 4.5ghz prime95 (1.42v-ish while idling - LLC Extreme takes care of the rest) ... that's why whenever i see these 1.38-1.44 numbers i am HIGHLY suspicious.

well you missed my point - i can just turn on shadowplay on my gtx780 and stream 720p/60fps like a boss without any performance loss
- but the quality is GARBAGE in my opinion.
regular cpu streaming using "very fast" obs profile provides slightly sharper looking stream at the same bitrate,
i can already do 1536x864 @ 45fps with my 6350 @ 4.55 ghz so 720p is not even a question,
what i want is to turn on a "slower" x264 cpu preset which makes the stream look even much better @ same bitrate but makes the CPU load skyrocket to levels where the stream will simply freeze after a fes second and task manager will show near 100% load on all cores
this is where s*** gets real. - i just want something more but am wondering what would i actually get...

I know what you meant. I stream using similar settings in OBS to what you want because I stream stuff that needs the better quality.

Each chip can be very different I had an 8350 that could run 5.0 ghz fine at 1.48 but have multiple friends with well over 1.5 running there systems.Can be a crapshoot.
well on some threads you can find ppl unable to get their 8320's over 4.2 ish ghz...
no idea if they just have "bent" hands or the cpu's actually come that crappy sometimes...

well.. it's twitch that i have problem with really... non partners can't go for too high bitrates or they can lose viewers,
partnered channels have the option to choose stream viewing quality,
i have very cheap, stable and fast fibre internet here so i could be dumping 20 or more megabit streams in there if i wanted to but who's gonna watch them...

I would say I have installed maybe 25-30 8320s and every one we oc'd got at least 4.2.ok - so there were some that didnt go higher? i need atleast the same 4.5 i already have on my 6 core to even make this worthwile, obviously secretly hoping to get lucky and run higher...
EDIT: i can do a stable 4.7ghz if i can lower my temp magically by some 5-10c (works with open window in winter)

i found a video on youtube of a guy overclocking the 8320 to 4.5ghz, prime 95 stable with the same exact motherboard i have ...

I got more than a few to 5.1 ghz with 1.52 voltage and h100i cooler and sabertooth r2 mobo some are identical to 8350's in every waydo you have a good idea of what voltage it could require around 4.5-4.6ghz? (acpu-z or other soft voltage reading under prime95 stressing all cores etc. - not idle voltage) taking into consideration the silicone lottery of course... i've seen people claiming it can do that around 1.4 volts which is insane to me since my 6350 requires around 1.5v to be prime95 stable @ 4.5-4.55ghz ... at such low volts i bet my CNPS12X could keep that thing cool even around 4.7ghz which is practically impossible @ 1.5 - it will go a few degrees over 60c and catch instability that way... and i only have 6 cores

well .. since i have a full fx6350 system up and running - jsut tryin to get to the 8 core as cheap as possible since i can sell mine real easy...
it just seems to me that once you go above 8320 territory you can't ignore a haswell... 8350 is just 40-45 euros short of a 4690k here in latvia .. and 4670k is 10 euros less
8370/8370e are 25 euros more than 8350... - still wondering if they oc any better (seriously doubt it)

i have never even physically seen a 8370 so no help there but if i was in your shoes i would sell the system and build to your needs with at least a 4790kdo you know what's required to stream using 2 pc's? how is the game/video passed through to the other pc?,
are capture cards used? im kinda thinking to just bite the bullet and grab the 8320 and see what happens,
if its not too good i can always sell one of them or just build a 2nd pc! - i got a 4gb 1866 cas 11 kingston pnp kit nearby that i could utilize... i got a 2nd monitor, some spare HDD and a cheap pciexpress graphics card too... just mobo/psu would need to be bought and voila! - but if it requires some expensive hardware addons then that idea can fly out the window...

I think you will be surprised how good the 8320 is give it a shot money trumps all and its your best price to performance increase chance bar nonehonestly even the 6 core is a fast little bastard! ... jsut when it comes to streaming i think the extra cores should provide a pretty decent boost to the processing since most games use 4 cores anyway...
after some quick googling it seems i would need a capture card for a 2 pc setup -i guess the plan is clear,
just gonna research a little what a haswell i5 can do in comparison before i bite the bullet....

Quote:
FlanK3r said:Many reviewers are "average" guys without deep knowledge of technology in process and without good knowledge for tweaking. Yes, this is true.
Stilt tested many chips and he knows more about AMD than most of us together. He is OC legend also. The changes between old and new Vishera are:
Piledriver module based Vishera die has been mass-produced in two different die revisions since the prototyping phase.
While all of the revisions have the same major die version (OR-C0), the minor revision has changed.
Initially the first mass-produced die revision was "India" (OR-C0i, prototype and ES only), the second revision was and still is "Juliett" (OR-C0j, retail) and now finally...
The "Kilo" revision (OR-C0k) a.k.a "King Vishera" a.k.a "Vishera Type-K" has arrived.
The "King Vishera" is initially only available in the new models, FX-8370E & FX-8370.
This is most likely the case with FX-8320E also, however I have not been able to test one of them personally.
The new version is likely to be phased-in at least in the other high-end models such as FX-9590 and at some point in all of the remaining models also.
The alledged metal tapeout of the new revision (alledgedly) occured in the beginning of July. So the only way to get a newer revision part is to get one of the new models, atleast in the beginning.
The differences?
- On average 18% less leakage*1 (0-38%) for FX-8370
- On average 53% less leakage*1 (14-106%) for FX-8370E
- Up to 300MHz higher overclocking margin *12
- 100mV less voltage required for the same clocks on average *1
*1 - Compared to an average FX-8320 or FX-8350 CPU
*2 - When not restricted by the cooling or the motherboard (VRM)
The E-version is the best choice for air or water cooling thanks to the ultra low leakage characteristics.
The non E-version does the same clocks however it might require use of a higher end motherboard (with better VRM) and high-performance cooling.
The non E-version has significantly better overclockability under sub-zero temperatures (phase, LN2) since the leakage levels of the E-version are too low for the purpose.
Having an ultra low leakage characteristics is great under normal conditions however under sub-zero temperatures the voltage requirements become a issue.
Basically the low leakage part exhaust the usable range of supply voltage prior reaching it's maximum frequency.
Based on my own tests, I would estimate that >95% of FX-8370 & FX-8370E parts will reach 4.8GHz frequency in 24/7 without a custom watercooling or a ultra high-end motherboard being a requirement.
As long as the temperature (see below) stays =<65 degree C or 149 degree F and the motherboard has even remotely a sufficient VRM you'll be fine.

so knowing that THIS is really not smart anymore compared to intel but out of pure love for the struggling AMD i changed my order to a 8370E (cost about as much as a 8350 did just recently)
- should be here tomorrow or day after - i will post back results and first experience!
