I5 2400 bottleneck the gtx 1070

RajatheBeast · Aug 13, 2016

Hi I currently own an OEM pc that I upgraded a few years ago with the gtx 960 and now I want to upgrade to the 1070 and a 1440 p monitor for battlefield 1 and I will also be playing overwatch and other fps games. Will my i5 2400 bottleneck the gtx 1070 in bf1 I know of course there will be a bottleneck but will it be very severe?

I'd say maybe in places. It's a lowish clock speed although still strong clock performance. Depending on game, but I'd say you should be ok

Depends, mainly the games you're going to play -except BF1-. If they're start to be CPU Intensive, i think you will have a limit there, but, hell, still an i5 strong CPU at today.

i5-2500:

Use the single thread value. You can then estimate the bottleneck if you look at CPU Scaling graphs.

The i5-4590 for example is only 13% faster than the i5-2500 (does vary slightly by application).

*In my experience, BF4 and similar would lose maybe around 15% roughly compared to an i5-4690K or similar high-end CPU, but even then your FPS may be more than sufficient for the task.

So I wouldn't worry too much about it. Simply TWEAK the game settings as per normal for the desired FPS.

Update:
Apparently the game MAY benefit from more than 8GB of system memory. You may want to look into that.

"Battlefield 1 will be built using the next modified version of the Frostbite Engine 3. We expect BF1 to require some pretty high end computer hardware to deliver reliable frame rates at 1080p on high graphics settings. Our early hardware analysis for Battlefield 1 is a GTX 970 or R9 290 recommended GPU, along with 16GB system memory and either a i5-6600 or FX8370"

The engine is fairly well threaded on the CPU side so will likely use close to 90% of your CPU (you would still likely have a CPU bottleneck on the main thread... a main game threads runs on a single core which is often where the CPU bottleneck occurs.. it's rare to be able to use over 80% of the CPU). It's hard to say how demanding it will be on the CPU. On one hand it makes better USE of the threads than other games, but on the other hand it may be processing more code.

As always we won't know until the game has gone Gold and been tested properly.

Yeah i can confirm that it will bottleneck i just tried battlefield 1 beta today and i have a i5-2400 with a gtx 1070 and i get around 60 fps and sometimes it drops below. Also some games wich are cpu intensive such as heroes of the storm and starcraft 2 drops below 60 fps too so im planning to get a i5 6600 or a i5 6600k i dont know wich one yet.
