Hey guys, just want to say sorry if this is a stupid question but i'm still learning and could not find any info online about this subject

Ok so last night i was playing Dead Space 2 on my new first build (i5 2500k) and i Alt-Tabed out of the game, while i was on my desktop i noticed on my coretemp graph that core number 1 was at 100% and the other three were on less than 10 % is this right ?

As i said earlier sorry if this is a stupid question but shouldn't and quad core cpu evenly distribute the workload over the for cores ? rather than max one core ?

Thanks guys

Edit: i have noticed the other three cores working on other applications but just not with this game :confused:
 
It does seem that the game is a single thread game, even though it is a new game. Did you have anything else running in the background? Like a AntiVirus scan?
 
Hi 1Day, i had the game Coretemp and EVGA Precision running.

I ran Prime95 when i first built the pc three weeks ago and every thing was nice and cool, this cpu is NOT overclocked by the way.
 
I would not get to stressed about it. If the system is doing what you want it to do then all is good. The fact that one core was maxed out is not a problem. Not all games are optimised for multicore CPU's. You might want to wonder over to the Dead Space 2 official forum and see if other users have noticed the same as you did. There might even be a patch that incorporates multi CPU utilisation.

That depends entirely on the program. Designing multi-threading is not just distributing the CPU load around cores as the CPU sees fit, but requires a whole different engineering of the code than single-threading. Each thread is its own little program within the program if you will.

However, I'm surprised that a game like Dead Space 2 would be only using one single thread (or at least one very heavy thread). it being a console port, it should have a pretty heavily multi-threaded system anyway, and the workload should be roughly evenly distributed. It would make no sense for them having a multi-threaded console game and porting to PC single-threaded (which would be hell to do and likely not even possible).

Or maybe they have a bug that just spins one thread really heavily, or runs a lot of threads on one core by mistake. I'd go with a unintentional bug :)

your cpu has a turbo mode, so even if it is single threaded, the cpu will run 1 core @ 3.7GHz, and the other 3 will be at 1.6GHz. so it will still run very fast and faster than an equivalent quad core without turbo mode.

to my understanding it runs all cores at the same speed, but as only one has any significant load on it, it knows it has the thermal/power headroom to turbo further than if multiple cores are loaded
