Downgraded from 4770k to 4670k. Performance difference in Starcraft 2?

post #1 of 8
Thread Starter 
So I had to downgrade to a 4670k. My 4770k died.. What do you think the difference would be in FPS? I've searched everywhere and got alot of mixed answers. Some say that since SC2 doesn't utilize more than 4 cores, hyper threading is pointless. Others say the extra logical cores helped but I think that it was a placebo effect for them. If any of you play Starcraft 2, I'm pretty sure that you've played Desert Strike and can agree with me that, that map in SC2 and along with a handful of others really tax the CPU.

Do you think hyperthreading makes a difference in SC 2? has anyone experienced this first hand?

The performance difference will be close to nothing.

SC2 only uses 2 threads so anything over that is useless. The extra 2M cache may make a tiny, tiny difference.

Also, can you not just get a replacement 4770K? You can't have owned it for long.

It was delided lol

What about this benchmark of single core to multicore in SC2?

As you can see the performance difference between 3-6 cores is none. The reason there is a performance difference between 2-3 cores is because that third core is basically doing the background tasks, taking load off the other two cores (to put it simply).

So basically only 2 cores????

I could of sworn by now Blizzard would patch their engine with multicore enhancement or something to improve performance. I forgot that it was built on DX9...thumbsdownsmileyanim.gif Hopefully Blizzard does something nice for its players when they release Legacy of the Void expansion.

Looks like I didn't have much to worry about since I will be losing negligible and minuscule performance.

Maybe in very low resolution like 720p could be a big
difference but if it`s 1080 near to nothing

Resolution has nothing to do with it in SC2. It's CPU bottle-necked at 1080P or 720P on nearly any GPU regardless.

Furthermore, resolution has never been a "fix" for CPU bottle-necking in any game. If the CPU bottleneck is at a high enough FPS then it doesn't matter, raising the resolution to drag the FPS BELOW the CPU bottleneck with a GPU bottleneck is not a solution to anything other than to try to take advantage of more of the available GPU grunt. If the CPU bottleneck was causing FPS dips too low at a low resolution, things will only get worse at a higher resolution. The way this gets represented and repeated is so misleading. It's got to stop.

SC2 is so single-threaded it's not funny, but there really isn't a way to do it otherwise with all the AI needing to be in sync as its processed.

Hyperthreading will only hurt SC2, so losing that doesn't hurt you but maybe the smaller cache could have an effect, but it won't be very noticeable.

Yup. It's as if some people believe 720p doesn't use the GPU, and going to 1080p magically takes a load off the CPU and places it on the GPU when in reality the CPU load is near exactly the same regardless of resolution.
