True.

The 3930K is a really good CPU and can handle a lot of processes. Even in-game my CPU usage doesn't go over 20%.

That's because it's 12 threads, so 20% isn't saying that much. It could be two threads being fully maxed out on a dual threaded engine with some background activity accounting for the last %.

As for some of your concerns Jubijub, you could get PWM controllers or something of the sort for more fan possibilities with a limited motherboard. This increases your options substantially. And I would agree that a 3930k would work well for you, especially if you have DDR3 RAM. That would be less cost to factor in there, and could help paying for an i7e easier.

Yep. When checking CPU load one needs to look at both single core load and overall load.

Except per usage monitoring is inaccurate. The best thing you can do is watch the active task CPU usage in the Process tab.

Best is msi afterburner with in game core usage.

It take lot of screen space but at least you know live what happen with the core usage smile.gif

It aint innacurate... Why do you says such crap.


Arma 3 for example clearly show 1 core at 80% most of time sbowing clearly a cpu bottleneck.


Those are accurate if you can understand them.


Can even show direct x issue and thread stall.

You can run tasks that are clearly single or dual threaded (or X threaded) and see that the per core monitoring isn't accurate. What should only be using X threads is actually showing that Y threads are being used, all in different varied amounts. I could put on some older games that are obviously single threaded, but I bet I'd see something like 3 of my cores running ~30% usage if the game required that much work. Same thing with stability tests that can run on X threads. Set Prime to use two threads, you would see 50% of your CPU used (on a quad core) yet you know only two are being used.

The only accurate information I have seen yet on per core monitoring is some 7zip/rar programs that are single threaded. While extracting files for a game update, I had one of my cores pegged to 100% on my 8350.

I remember everyone getting flustered about Watch Dogs "using all eight cores of an 8350 and it wasn't maintaining 60FPS" but check the total CPU usage - it was around 50% total, which after factoring in required CPU usage for background tasks and screen capture, was a little bit less than 50%. It does use 4 threads quite well, but it wasn't using all eight and still hit a CPU bottleneck.

This discussion has happened a lot in the past, and it is true that per core resource monitoring is inaccurate. Someone else who can explain it a lot better and with technical details may stop by. Either way, I don't want to continue in this thread. I don't want to derail it with this topic.

Optimisation issue. I played assasin creed 2 with a 4790k at 4.7 and i could not hold 60fps.

But yea just realised we arent on an open thread. Sorry frown.gif

It's not accurate because your OS's CPU scheduler moves the heavy thread around. (In some cases, the app itself will keep generating new threads but run them in a sequential manner as well.)
