Will my Intel i7 2600 be bottleneck with my new R9 380?

TheFnaticFAN · Sep 30, 2015

Hey! I recently upgraded my GPU to Msi AMD R9 380.When I bought it, i dont know theres such thing called bottleneck, until i found out yesterday.But now im kinda worried because i have a third gen Intel core i7 2600 non k version CPU. Is my rig botlleneck?

Pls, I need help! Thanks.

No, the i7 2600 is still a strong CPU.

RJMadCat · Sep 30, 2015

I also have a I7 2600, The cpu is godly for its time. I run it with a R9 390 and still the bottleneck is the GPU not the cpu!

The term bottleneck needs to be taken lightly and you need to understand what it REALLY means. Every computer or cellphone or whatever has a bottleneck. It is just how hardware works.
If you spend $10 000 on a PC, it will still have a bottleneck.

A little bit. Nothing noticeable, just a couple FPS gain by buying for instance the current fastest CPU.

RJMadCat · Sep 30, 2015

a Little bit? The cpu will not bottleneck that GPU. Nada, nothing, zero.

Suzuki@1473780084@1473780163 · Sep 30, 2015

That is incorrect.

The 2600K will not bottleneck a 380 or 390 or etc.

The 2600K will let the video card reach its full potential. But the 2600K will score 1-2-5 frames less than a 6700K, not because it is bottlenecking, but only because of the slightly higher productivity of the 6700K.

And this does not qualify as the term - "bottleneck".

TheFnaticFAN · Sep 30, 2015

Thank god !Yeah Thanks for telling me!

Suzuki@1473780084@1473780163 · Sep 30, 2015

OP is using non K. and It's more than 1-2-5 frames compared to the 6700k, more like 20 frames on avg.

Anyways, enjoy your new GPU, OP.

Shneiky · Sep 30, 2015

So it is not a K so it is 100 MHz lower clocked.

Just an example.

http://www.techspot.com/review/734-battlefield-4-benchmarks/page6.html

The I5 3470 which is Ivy bridge 3.2 GHz I5 and it is weaker than a 2600k scores only 1 frame less than a 3.5 Ghz 4770. Clocking the 4770 to 4GHz (4790k) gains 1 FPS. The 4790 and 6700 are 1-3 frames off of each other.

And you take this and put 1-3 FPS on top of the 4770k to get the 6700k

Where are your 20 frames? That is it. 2-3%. There is no real life difference at 1920x1080 or up resolution.

The 2600 is perfectly fine and the op does not need to change his CPU. The 2600 is not bottlenecking a 380 and it wont be bottle necking a 980 Ti, a Titan, a FuryX either.

No it is not incorrect, don't be stubborn.

Suzuki@1473780084@1473780163 · Sep 30, 2015

Do the math then. 2600 3.8, 6700k 4.2. I can do the math for you if you want.

Isn't that what bottleneck means, limiting another component, in this case the GPU?

Suzuki@1473780084@1473780163 :

That is EXACTLY what it means and shows that you are wrong.
My i7 2600 does run everything perfectly smooth without a hic up, I run it with a R9 390 GPU Sapphire Nitro.
When I am in Games I can see how the GPU work rate goes up and similar my CPU work rate goes up. My GPU reaches its peak long before my i7 does.

That means the GPU is the bottleneck, and the r9 380 would be even a bigger bottleneck.

We are not comparing i7 that is 2 generations old 1vs1 to a new gen i7. he wants to know the bottleneck and if his i7 can handle his r9 380 which it can.

Look at the list and see if it is recommended to upgrade or not.

How much FPS are you averaging with that R9 390 and i7 2600? And let's find out how big the difference is. I never said that the 2600 would bottleneck the R9 380 to the point it would start stuttering, that's ridiculous. Read my OP:

"A little bit. Nothing noticeable, just a couple FPS gain by buying for instance the current fastest CPU."

And I'm not absolutely wrong by saying so.

RJMadCat · Sep 30, 2015

The thing that sparked my argument to you is not that last part of your quote, but the fact that you think the cpu will bottleneck the GPU even a little.
I agree that if you have the top current skylake cpu you will get better performance, however it is not because the cpu is the cottleneck, but more to do with the rest of the build, motherboard bus speeds memory speeds etc that improves the whole pc together which gives you a few more FPS.

imo, a bottleck is the thing that is making you feel like your pc has reached the end of its performance.
This argument has now gotten to a stage where i do not see anything usefull coming out of it for the OP Other than his i7 2600 will run perfectly fine with his r9 380 with no problems.

Suzuki@1473780084@1473780163 · Sep 30, 2015

Keep in mind that an i7 2600's usage at 50% isn't the same as an i7 6700k's usage at 50%. I absolutely never said that the difference is big, but it's there, and people mostly ignore it. Is it going to be unplayable?`No, Intel increases IPC among other things in such small steps, that it's not even worth mentioning. Bottleneck is just limiting another component, technically you always have bottlenecks in a system, be it from RAM, or basically everything is bottlenecking your motherboard for instance, because you're not utilising 100% of it's features and functions. It's a word that I see used a lot, and I don't agree with how most people see a bottleneck as. I think it's wrong.

Shneiky · Sep 30, 2015

Well I am sorry to say, but you have been using the word in the wrong sense.

1) If you get 100 FPS with I7 2600 while your video card is at 100% and your CPU is at 50% - its all fine.

2) If you get 110 FPS with I7 6700 while your video card is at 100% and CPU is at 50% - it is all fine.

This is performance difference between 1) and 2).

A bottle neck is:
3) You are getting 50 FPS and your CPU usage is at 100% and your video card is at 50%.

That is a CPU bottle neck. The 2600 will not bottleneck any modern video card. Sure - the system overall will score less, but all the components will function at peak. The fact that the peak will be a little lower with an older CPU is a performance difference, not a bottleneck.

Will my Intel i7 2600 be bottleneck with my new R9 380?
