Whats your Haswell CPU clockspeed in GHz for gaming?

  1. higher? please consider posting below.

    Ahh so that might explain my cores being loaded only to ~40%. Would that mean that with HT on, 50% load is 100% actual load?

    Wait, come to think of it, ive seen loads of 80 ish sometimes, how could that be explained?

    Thanks for your post, it is very educational.

    So pretty much the aim would be to clock the CPU as high as possible.

    After tinkering last night, my optimal setting is 3.0 GHz. This way, I'm constantly on the brink of thermal throttling, so the cpu stays at a constant 3.0GHz. If I clock to say 3.4 GHZ, thermal throttle will occur and most of the time it will clock below 3ghz and then up to 3.4 again.

    I prefer the constant 3.0ghz to the inconsistent throttling.

    Now its time to order some GC Extreme and remove my crappy stock TIM application.

    EDIT: would I benefit from disabling HT? Most games dont seem to utilise 8 threads even in this day and age and I heard HT only brings temps up.

    While in theory it should be 50% load, HT is only ~30% of benefits at best. As I did say, I've seen single threads being maxed before. I thought I had a great example, but this is the best I can get on short notice with my overlay on. FF XIII is the culprit; look at that core #0 load =D

    There is no benefit to be gained from killing HT on quadcores. Even if the game doesn't use it, other programs can and do, like voice chat or music players, etc.

    An app which is not multi-threaded properly is CPU-bound at 50% of overall load on a Hyper-Threaded CPU is what I meant. 30% ideal perf gain from HT is separate from the CPU load, otherwise HT would double throughput (+100%) which it obviously does not.

    That's an example of a predominantly single-threaded game, like this one. Most last-gen console ports are dual- or tri-threaded since that is the number in PS3 and XB360, with a large main thread due to DX9.

    Yes, if the reduced temps from disabling HT allow your CPU to clock up higher, you will get better performance in most games, particularly single-threaded ones like BL2.

    I'd like to try that out. I'd imagine a higher clock with the same temps and 'only' 4 cores would achieve better results.

    The option is not in my bios though...

    Any other findings that could be interesting?

    What my understanding is, is that increasing resolution increases CPU hit per frame, but decreases CPU load overall by forcing a GPU bottleneck.

    It's like... if you took a 4.5GHz haswell i7 and two 980Ti cards and ran something at 720p then at 1080p, you're probably gonna find you get less FPS without actually maxing the cards at any point.

    The increased CPU hit is so far negated by the reduced CPU load (due to GPU bottleneck) that people don't consider it.

    In what way? Increasing resolution is an entirely GPU-bound operation.
