Huge CPU Bottleneck, How should i get rid of it?

TheOfficalTanner · Aug 2, 2013

Hello,
I recently bought a 7770, played far cry 3 with it and im getting the symtpomts of a cpu bottleneck (Same fps on low-high) I only have a dual core 5400k, but its clocked at 4.2ghz, this is the cpu bottlenecking right?

Ive got a couple of options to look at

I can:

A. Buy x4 750k for $89
B. 8120+mobo(Don't really want to cuz i just upgraded mobo yesterday)
c. overclock, I have a hyper101, and i plan to get a secound fan when my rebate get back. I plan for around 4.5ghz

Current temps are 50c load (should stay same or little higher when upgrading fan)

Also, Im downloading bf3 and would that see the same effect as fc3? I think bf3 is more gpu intesive

(all im looking for is a playable framerate i.e. 30+)

it is your VGA not the CPU

7770 is very slow card for that game.

Well, I see other vids on youtube getting 35-40 fps on high, and im getting 15-25 on low...

SNA3 · Aug 2, 2013

TheOfficalTanner :

Did you pick the GHZ edition? besides 40 fps on high is imossible with 7770 ...

here is your benchmark ..

SNA3 :

Here it should be able to get 60fps on low...im no where near that.

Actually, it's two fold. The video card AND the cpu.
http://www.tomshardware.com/reviews/far-cry-3-performance-benchmark,3379-7.html

your cpu is close to the x2 240 performance.

Benchmarks that include your video card.

Yes. its clock at 1100mhz and ram at 1225mhz, it says its only on 40% load on fc3...

TheOfficalTanner · Aug 2, 2013

Guys, I would like to announce that i went full retard, I also had prime95 running in the background xD

SNA3 · Aug 2, 2013

TheOfficalTanner :

LOL

TheOfficalTanner · Aug 2, 2013

SNA3 :

Yeah now its around 50-62 medium, 30-37 High...thanks for the help i guess lol

Daniel Tarver · Aug 2, 2013

I would definitely says its your cpu.. I ran FC3 on my 1080p tv with my xfx 6850 without an issue on medium to medium high settings.. But I am running a Core-i5 OC to 4.2 which makes alot of difference to the dual cores.. especially if its not even a core-i3

griptwister · Aug 2, 2013

The CPU isn't even that bad, it would bottleneck a 760 and up, but a HD 7770? Come on! LOL!

TheOfficalTanner · Aug 3, 2013

griptwister :

Im pickin you as best answer, it works great! plus its at 4.2ghz so is far from stock...Im just glad there someone out there that agree that you don't need an i5+760 or higher to play good games...this i was a budget build at its great

hafijur :

Noticed a slight bottleneck but its better than integrated on it...beside that isn't overclock to 4.2ghz
And i chose the 5400k because of the graphics, looking back now i shouldve went with a pentium, but i wouldn't of liked like low frame rates in minecrat

That cpu will massively bottleneck a 7770. 2163 points on here shows it very slow:
http://www.cpubenchmark.net/cpu.php?cpu=AMD+A6-5400K+APU

The 7770 will run at like 30% of its potential most likely.
http://www.xbitlabs.com/articles/cpu/display/trinity-vs-ivy-bridge_9.html#sect0

You need an i3 3220 minimum for a 7770 or an fx6300 or an a10-5/6800k or fx4300.

edit: Look at this, intel cpus with there own igpu the i3 3225 has the hd 4000 wins on f1 2012 which is a slightly cpu intensive game as the cpu is so much faster yet going by 3dmark11 scores the intel system should have no chance lol.
http://www.xbitlabs.com/articles/cpu/display/trinity-vs-ivy-bridge_10.html#sect0

2636 was my score, still not comparable to the best, but i feel like it works just fine for running a video game and not multitasking

griptwister · Aug 3, 2013

I appreciate that! Thank you for picking me for best answer! Also, this hafijur guy is going to do everything in his power to convince you Intel is better. Which he's not wrong on that. But his numbers are completely off. lol.

TheOfficalTanner · Aug 3, 2013

hafijur :

Hey lets all face it...there a bottleneck in every system...now we don't need to get into amd fanboy intel hater/ vice versa...point is we got the problem fixed right? please stop...

TheOfficalTanner · Aug 3, 2013

TheOfficalTanner :

Yes, the solution that was chosen is completely wrong. If you are going to use a 7770 with your a6 5400k then I reckon I will get higher fps on my £220 laptop with an i5 3317u and gt 640m as my cpu is much faster especially for games.

No it wasn't, I asked if my cpu is bottlenecking, and when i closed prime95 and lt worked, he said it didn't bottleneck a 7770, it doesn't (to a noticable extent)...answer solved....

In a sense, Hafijer is right. You're getting 2FPS less than what you should be getting if you had an Intel system!!! *rollseyes*

I play with an old phenom II x4 840, which is essentially a re branded Athlon II x4, but it runs games good still with my HD 7870, it provides me with what I need until I get to playing Crysis 3. Lol, there is no explanation as to how a FX 8150 is bottle necking your HD 7770.

griptwister · Aug 3, 2013

Actually, I got threads mixed up with similar titles. Either way, that CPU isn't enough to create a major bottleneck. Obviously, considering he got a performance gain disabling a specific program.

I should have known when your posts disappeared in the other thread.

TheOfficalTanner · Aug 3, 2013

its around 50%

its okay guys, ill upgrade to the x4 750k around christmas so i don't get f..d to hard by these new games...and don't tell me it wont be enough because i dont care, i just bought a new mobo this week and i won't switch to intel or amd (haven't desided) until next summer, thanks for the help but i didn't mean to start a war...

griptwister · Aug 3, 2013

You didn't start a war. I made a mistake, and hafijur is trolling people lol. A 750K will be enough for your needs

I have the a6-5400k paired with the R7 260X and i'm convinced i'm getting a bottleneck. Would upgrading to the x4 750k solve this?

griptwister · Dec 24, 2013

Yes sir! You'll notice far better FPS!
