cpu bottleneck ?

[Edgar R. Zakarian]

Fx 8350 stock

hd 6990 (880mhz)

16gb ddr3 1600mhz

Asus savertooth 990 fx rev 1

How do I know if my CPU or mobo are holding my monster gpu back ?

Fps fluctuates A lot in all games. Shadow of mordor 40-120 avg 60

Cs go 80-260 avg 135.

Any ideas ? Heard The CPU sucks ?

The cpu has bad single threaded performance, so it will be a big bottleneck is CS (and quite a few other games)

You can let go of the "monster GPU" superlatives, that card roughly compares to a 280x now.

 

Anyway, MSI Afterburner and monitor GPU load for the obvious bottlenecking. But drawcalls will always be pretty poor with FX CPU's, especially in games that require fairly little GPU horsepower like CS:GO.

@, CS:GO actually has suprisingly good multithreading, atleast to 4 cores. I got 100% on all 4 sometimes when I play it.

Just put an FPS cap at 60, unless you're on a 120 Hz monitor.  This will prevent wild fluctuations for the most part.

 

Shadow of mordor make sure you're not on ultra textures because that will exceed your VRAM.

 

 

Try running CSGO with crossfire off and see if that helps.

6990 in general is crap... got bettwr fps out of overclocking a gtx 480 than i did my 6990.

[Edgar R. Zakarian]

Well gpu usage is on 40% on both. And. CPU usage is Like 70% on 2-3 cores Where The rest are at. 10.

It's because AMD.

 

Relevant statistic, because you mentioned this game in the OP;

 

Yes, that is a dual core i3 stomping all over the 8core FX series. Meaning the game has a high drawcall amount. Meaning the threads will be very heavy and to get a decent amount of scaling, the per-core performance has to be high.

wait What??? how is the i3 better than the I5 above?? what?????

are you serious??? OUCH

I do have a 120 FPS monitor :-D all is high, except textures = medium. As only 2GB VRAM each card Runs fine generally. just fluctuates quite a lot. I quess it´s my CPU bottlenecking..

 

However for a computer less than 1000$, I guess this is a good setup. - Cheap because I bought it all used here and there.

 

All of it bought 1-2 years ago:

 

Radeon HD 6990 241,21$

Asus sabertooth 990fx rev 1 + FX 8350 192,97$

RAM = New 190$ approx.

PSU 750W Aerocool gold. 750V 80,40$

ouch hahah.

Guess it is the CPU bottlenecking the card then??

 

My cs go fps looks pretty much the same as this actually. Maybe it´s not the cpu anyway then??

Don't know what settings that guy is rocking, but i get 200-300fps in CS:GO ;/

 

 

wait What??? how is the i3 better than the I5 above?? what?????

 

 

That's a sandy-bridge i5. It's not faster than the haswell i5. Also, it's so low on the scale due to the min. fps.

[DirkW]

wait What??? how is the i3 better than the I5 above?? what?????

4th generation i3 vs 2nd generation i5. That's how.

 

The 144 vs 4670K's 143 however - that difference is within margin of error. But it seems that 2 cores with hyperthreading in this instance show the same performance as 4 cores with no HT. Interesting.

the cpu is not a bottleneck (and shadow is a nvidia game)  <_<

 

but, keep in mind this...

 

 

GPUs start to run "strange" when they pass the 99c and touch the 100c 

 

(is some type of security to not damage the card) 

 

 

and you have two cards in one (with a lot of use)

 

check (with GPU-Z) the temps of the cards on load (if they touch the 100c)

 

 

if they do...

 

is time to do some Undercloak to the GPU to stabilise temps

 

(and a clean card fan help a lot also)

 

 

also... to do this, i like put -50 mhz on the GPU (forget the Vram)

 

and go down until i reach something like a 80c

 

 

add to this that nvidia "know this" and like make all AMD card run hot just because if

 

(i am not a fan of the green side)

it's not, look at the minimum...theres a reason why the CPU are ranked by minimum FPS...it's because it's the stat that is relevant...it's the minimum that you notice while playing...not the 144FPS for a brief instant while looking at the sky or at a wall!

I use MSI afterburner and Logitech G15 keyloard LCD, to monitor all temps and usage.

 

Gpu temps never exceed 80'C, and usually stay on 77. AMD´s fan profile makes sure the GPU doesn´t get too hot. CPU never gets hotter than 65'C.

So thermal throttling is not a problem in this c2ase

You´re obviously wrong

4-500 fps with that cpu. Seems I´m getting GPU LAG.
