games use ???

[The Alias]

so how do games use cpus ? or what part of cpus and their functionality do games employ ? like ue3 or frostbite for example

I am not familiar with those games but in general most games avg about 50% utilization , if its a simulation it might be little bit more . they tend to be more GPU dependent, at least most newer games in later 5 yrs or so .

They use all parts of a CPU, they are especially heavy on floating point calculations including SSE like instructions.

It kind of depends on the game. Some games are more cpu heavy than others. It just depends.

I can definitely tell you, going from an C2D E6400 @ 3ghz to an i5-2500k(at stock) with the same video card, I had significantly more performance in games making the change. So it does make a difference.

Obviously a video card is the main component of game performance though.

UE3 will use all 4 cores - 3.7Ghz i7 920 HT/on brings the engine to life, imo

Some games will provide helpful information to let you know what aspects use the CPU most.

For example, when you go to the configuration menu in Starcraft 2, you'll see a bunch of different settings like whether to use basic or ultra shadows etc. When you hover over the setting, Starcraft 2 will pop-up a little message saying something like "This feature relies on your CPU" or "this feature relies on your video card". So, you can determine what settings to bump up or bump down if you know you have a strong or weak CPU.

For my computer running Starcraft 2, all my video-dependent settings were maxed out to Ultra, but my CPU settings were reduced to high or medium.

That's helpful to know because if I really value those settings, I can upgrade my CPU. But I know that upgrading my video card won't get me any more benefit, because my video card is able to max everything out. A faster video card won't bring me any more performance, but maybe if I get a faster CPU and a huge 1600p monitor, then maybe I could take advantage of a faster video card. So in my case, a new CPU could help me out.

the real question was what part of cpus do they use . Bright candle's answer regarding floating point operation was more along the answers I was looking for
