Bottleneck?

[LurzKesh1138]

Would sli 780's be bottlenecked by a 4.4ghz fx 8120 w/8gb of ram? I'm thinking itd be fine but would like some outside feedback

[Swndlr]

depends on what youre trying to do, most likely, yes they will.

[Hasleo]

forget what i said.... mistook the cpu... ;/

[Fate]

no, even a triple sli gtx 980 would not be bottle necked

lol....

 

OP yes it will bottleneck pretty significantly in just about every game compared to something like a 4690k.

well.... i agree 

[Faceman]

Yes, even a single 780 is bottlenecked by an FX8.

my single GTX 780 was bottlenecked by my 4.6GHZ FX-8320 CPU so i had to upgrade...that says it all...major bottleneck yes.

[Mush Brain]

Yes sadly.

[dandrix]

Considering its Bulldozer then yes unfortunetly, would be better off on Piledriver 8 core, nevertheless what some of the guys say here, people running dual high end GPUs on AMD octa core chips are easily achieving over 120 fps avg in modern games maxed out, if thats not enough go with i7 then.

haha you are so funny...120FPS...that thing can't even achieve 45FPS in many games.

Also bulldozer is only 11% slower than piledriver...not much a difference between the two.

With that one you really reveal who your are mate.

[i_build_nanosuits]

yeah fine...but the fact remains the same the AMD FX lineup does greatly limit the performance of higher end graphics card and it's not a very good gaming chip and it never has been...and will never be.

and check for yourslef, 11% per core is the performance delta between piledriver and bulldozer if that is what you are refering to.

Poor

In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The AMD is also cheaper but significantly more power hungry which counts strongly against it as a sever proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K will deliver better performance.

Well thats your opinion, anyone with piece of real experience and unbiased point of view beggs to differ. Good night bro.

please re-read previous post has been editied with VERY SOLID evidence for you to look at.

Sorry to burst your bubble, but the 8350 does lag behind and bottleneck high end GPU setups. And good night to you too

[Faceman]

Just ignore and report dandrix.  Time to give him the Cokeman, I/O treatment.  If moderators won't police this forum, then we have to.

My AMD fanboy mate who says he IS an AMD fanboy, he has the X6 Phenom II 1100T and the FX 8350,....had to go Intel because the top options from AMD were limiting his GPU's, They were not fast enough for powering his 2x970's in many of his games.

He was pissed off to no end,.. he loves AMD, but they don't have what he needs,... which is 100% efficient usage/performance from BOTH his GPUs.

 

 

Everyday we have newly created threads for users not getting 100% out of their GPU's.. ESP Crossfire/SLI users.

Here is one JUST created in the last few mins... http://linustechtips.com/main/topic/322800-gpu-not-running-at-100/

There are many like this created each week, FX4/6/8 it doesn't matter, it's just not good enough.

As an AMD fanboy, I will willingly admit that they are lagging behind Intel, and I will willingly admit that Bulldozer is garbage compared to Intel's 3rd and 4th gen architecture (can't remember the codenames).

 

EDIT: This is also after I've argued in favor of my FX-8350 as compared to a 4560K

don't worry i have argued in favor of my beloved AMD FX at first in here too...but i've been wise enough to start monitoring my GPU loads in games and minimum FPS with fraps...and then i went WOOOOOOOOO something is not right here...then you run benchmarks and start looking at numbers with an unbiaised eye and you have to come to the conclusion: even at launch back in 2012 the AMD FX vishera was lagging significantly behing intel's offerings of the time (sandy bridge i5 and i7's) and intel has released 2 generations of cpu's since while AMD has been doing nothing on AM3+...focusing on FM2 and APU's (which is not a bad thing by any means) but they just gave up and kept cashing in...and even to this day many people still think they are good offerings because they look at ''core'' count and clockspeed...but the performance is just not there.

 

The AMD FX is fine to feed mid-range GPU's in AAA titles at 1080p...if you already own one it's fine to keep it...but if you are serious gamer playing AAA titles with a higher end card and looking for 60FPS max settings gaming...not the chip for you.

The AMD FX-8320 can also be paired with a cheaper 970 chipset board (6+2 power phase minimum) and be great as a budget oriented workstation to render videos and stuff like that...but other than that it's really not a good choice here in 2015.

[SkilledRebuilds]

Yep, IPC... grossly underestimated in it's need to do things properly.

indeed.

[i_build_nanosuits]

And this is the reason why I will never get another AMD CPU, haven't owned one since Athlon X2 days. AMD always failing at catching up to Intel lol.

well...if you look back in the past...AMD has been on top A LOT...they have had a lot of mighty chips that intel would have loved to have back in the Pentium 4 days...they might come back on top someday if they have a major breakthrough or something...i don't discredit AMD, you never know what is going to happen.

Whatever you do, Do not SLI those 780's with the FX cpu.

[brandishwar]

The 780s are going to be fine on SLI with an FX CPU. I run two 770s in SLI and don't have any problems at all.

monitor your GPU loads in games with msi afterburner and turn off vsync before you make stupid claims like that...of course it does unless you game at 1440p or higher resolution.

My 4.6GHZ FX-8320 was a major bottleneck to my SINGLE GTX 780 in many games.
