CPU drastically affecting FPS in games?

[xnoobftw]

Hey guys! I know this thread has been made (by me http://linustechtips.com/main/topic/289445-bottleneck/) and that there are 2 guys discussing relatively well with this topic. I made a new thread in order to get more opinions on this (Would CPU change the FPSes of games by alot like the link i placed on top) Such as my personal CPU (i5 4440) would it bottleneck 2 290x at 1440p? (I get loads of mixed answer with this) And the ultimate question would be is my i5 4440 bottlenecking my 290x already? (1080p) And would it bottleneck at 1440p?

 

Thank you for your participation

It's not that simple. 

Game A may give 20% more fps with a 4.8GHz i7 than your i5-4440, and Game B may give 1-2% more fps. 

Furthermore, a theoretical 5.6GHz i7 may give more fps than a 4.8GHz i7 and so on, which some people may call a bottleneck.

 

It IS a bottleneck compared to an overclocked i7 depending on who you're asking and the games you're playing, but in my opinion, it's not worth it to upgrade your CPU if you're running two 290x's at 1440p. It's not like you're going to lose a crazy amount of FPS or anything.

Whether or not a game is reliant on the CPU depends on the game, you can't base it on a genre by genre basis(with exceptions) as almost all games are coded differently. The only genre's that you can say are heavily reliant on the CPU are MMO's and strategy. As to whether your i5 is bottle necking your 290x, it's not. It might bottleneck two at 1440p a bit but it wouldn't be by any large amount.

Already gave my opinion on this. Yes, to some degree (varies).

Any one with common sense knows that CPU is not a bottleneck, but on the other hand an i5 K SKU will deliver higher frames at a much higher clock.

[Majestic]

Indeed, bottleneck; no, but would a i5-4690K @ 4.4+ ghz get squeeze more frames/drawcalls out of the 290X crossfire setup? Absolutely. Sometimes even by 20-30% (see previous post).

Hmm would you recommend me changing to something like a xeon? Or should i sell my 4440 and h87 mobo when the time comes and get a new pair?

(Take note i'm pretty poor... just a student here!) Or would you ask me to stick to a single 290x and upgrade to a better single gpu when the time comes? (Keeping my cpu and mobo)

Lol, you're saying that though without actually using an old CPU like a Core 2 Duo E8500 @4.05GHz, or a Xeon X5450 @ 3.25GHz. Trust me, CPUs can and will bottleneck GPUs (my GTX 970 proved that).

Well seeing as the board runs the second slot on 2.0 4x that already cuts out some of the bandwidth. Added a CPU that is not really meant for running 2x290x... no. Stay with your current system.

What would be the first upgrade you would recommend? (Assumung something like the 390x were to be released)

You should upgrade to a motherboard that supports at least the second PCIe x16 slot at x8 speeds. Everything else looks fine.

[Majestic]

Why not just ride it out. The CPU and GPU are well balanced. Just upgrade whenever the system becomes too slow.

 

Even upgrading the board seems pointless tbh.

a bottleneck means the gpu cannot run at close to 100% it does not mean that you cant get 9999999999999999 fps then its a bottleneck

No it doesn't. It means there's a predominant factor limiting performance, it is also very subjective and up to the owner to decide whether or not it's significant or not.

What is severe to you (say 20%) might not be severe enough for someone else.

 

Compared to a 4.5ghz 4690K or 4790K, it ranges from 0% to 35% (depending on game) by how much lower it scores.

Did you not read my post?

 

And aren't you the guy recommending FX-6300's to people with 290's saying it won't bottleneck?

[spartaman64]

And aren't you the guy recommending FX-6300's to people with 290's saying it won't bottleneck?

yes because the gpu will run at near 100% and there is no way a i5 4440 will bottleneck a gpu even something like 4 way sli 980

A Core 2 Duo @ 4.05GHz limits my GTX 970s performance to 49%, my Xeon had the limit at 79% when running @ 3.2GHz.

Ok, but that doesn't mean he wouldn't get drastically better performance by going with something like an i7 and overclocking the snot out of it. 

Like I said, it depends on who you ask/how you look at it. Some people say that it's a bottleneck when you could be getting 20-30% more performance with another CPU, some people say it's not.

[spartaman64]

you guys are saying its a bottleneck if your cpu doesnt allow you to get the highest possible fps that is untrue. sure you will get performance gains if you get faster cpus but that is just that performance gains not removing bottlenecks. it is only a bottleneck if prevents your gpu from running at close to 100%

[spartaman64]

i am not saying you wont see higher performance with better cpus im saying its not called a bottleneck if it doesnt limit your gpu from working at close to 100%

[Majestic]

Yes. It does. If you decide that 20-30% less framerate is a bottleneck to you.

 

It's pretty simple dude...

that is called better performance not removing bottlenecks

[spartaman64]

These people sometimes.

that wouldnt be called a bottleneck its called the performance is too low
