i5 2500k bottleneck?

[Juliogol]

Hi guys!

 

Here are my specs

 

Core i5 2500k @4.3 Ghz

Saphire Tri x r9 290

120 GB SSD

12 GB RAM

Cooler Master Silent Pro 700w PSU

 

Thing is I play mostly Battlefield 4, Multiplayer and with my cpu I am getting a 90-100% usage while gaming on large maps with 64 players. Does this mean that my CPU could be bottlenecking my GPU? And if so, would you recommend a CPU upgrade to i7 or is it poitnless?

 

I get good frames with Mantle enabled, but with DirectX I get somewhere between 50-80 FPS...

 

Thx!!!

 

EDIT: AsRock Extreme 4 Socket 1155 Mobo

not at all.

You can easily tell. Monitor GPU load with MSi afterburner. If the GPU load isn't 100% you got yourself a bottleneck.

[ilikemacandpc]

You could probably up clock your 2500k a bit more, but there's no bottleneck. 

[Enderman]

I'm pretty sure its because battlefield 4 can use up to 8 threads. So in this game it is a bottleneck. But currently this is the only game that your CPU is bottlenecking, so is it really worth spending $500 for a CPU upgrade just to play this one game at a couple more fps?

What he said. If the game is very CPU intensive it will appear as a bottleneck but only in games that are CPU intensive. Normally your 2500k will be more than powerful enough. Just enable Mantle and you are good to go.

[Juliogol]

Yep, with directx I get round 60/70% GPU usage, while on Mantle I get 100% usage most of the time.

Its more an issue with dx 11's inefficient use of the cpu than anything else.

I see the same here in bf4 with my i5-2500. Fps drops accompanied by gpu usage drops in dx11 and consistent high fps and gpu usage with mantle.

Hopefully dx12 helps with this as well in future games

Raise the cpu clock up or use Mantle.

Not only that, the driver overhead on AMD's side seems to be bigger than on nvidia - both dx mode. As you notice the big gap between the APU/780ti and the 4770K/780ti the APU is bottlenecking badly, same thing with the 290x in dx mode. So focus on the APU for now, the difference between the 780ti/apu and 290x/apu is quite large thats mainly because nvidia drivers suffer from less overhead which overall reduces some cpu bottlenecking, hence why they gave their 337.50 the name "wonder driver cpu bottlenecking". Ofc when you're feeding the 780ti or 290x to 99% the difference is like it should be 5-10%.

Translation: Direct X sucks

[Constantine]

The 2500k is still fine. Oh and OC that baby to 4.8 Ghz. It should be capable with the Extreme4 if you do it right.

[SkilledRebuilds]

Plus BF4 isn't the best engine as it can create its own bottlenecks to a degree, compared to almost any other game you throw on your i5/290 BF4 will be the worst culprit of looking like there's a bottleneck.

If every other game is fine GPU usage 98-100% & BF4 is dipping GPU usage down It can be the engine at fault.

My i7 2600k @ 4.8Ghz still sees my 290 having 85-100% usage on certain situations on certain maps (Shanghai being pretty bad/worst)

Yet every other game works flawlessly, temps are awesome. Just BF4 being BF4.

Overclocking will bring your performance up a good amount in regards to MIN/MAX Fps, and Average will gain/stabilize a bit better overall., so doing that is a nice bonus.

Got it to 4.3 Ghz up to know. I am a bit of a noob when it comes to OC. I have a Hyper 212 Cooler, and @ 4.3 Ghz temperatures are in the mid 70 when gaming for a couple of hours, don't know if I have room for more OCing  :mellow:

Oh. Yeah, I could only get mine up to 4.4 with the 212 before the temps got too high

that seem pretty hot. what voltage is that at. i'm getting mid 70's at 5ghz under a better cooler, but im running 1.4v as well

[felixthemaster1]

I have the same CPU and I was wondering if getting another 290x would bottle neck it? (2 x 290x crossfire) If so maybe I will finally get to overclock it but i don't know if people who overclock only do it for the numbers or actually leave it running overclocked

I have it on Offset mode on the bios, and its around 1.3 / 1.35. It get to 70/75 but after a long session of gaming.

is 4.3ghz the highest you can get at that voltage? most should do 4.6ghz under 1.4v easy.

Yeah, I have heard that nvidia's DX11 driver has better multithreading to a degree, because AMD drivers don't support directx 11 buffered commandlists (afaik it was a conscious decision not to support this feature from AMD, because they weren't happy with its implementation in DX11 and weren't able to get satisfactory performance results on their architecture with it, in some cases it actually performed worse).

Just multithr optimizations which doesnt do much if the game itself isn't properly threaded. The game itself has to be better threaded, it basically does nothing to a game like WoW which only has 2 main threads.

The reason why nvidia did better is because their drivers suffer from less overhead. A driver always has some overhead that obviously effects the cpu performance which could lead into a having a cpu bottleneck or make the cpu bottleneck bigger. Nvidia can only reduce the driver overhead, they can't do anything if the game itself is extremely cpu bound such as wow where as an new API can do much more.

Tried @4.5ghz but blue screened after five minutes of Prime 95

OK! I'll try and update here. Thx!!
