How many cores does DOOM use?

[pRopaaNS]

Hey, putting i5 in minimum requirements seems like a joke, it's same as implying that the game uses all 5 cores at same time to run. So how many cores does it use?

I've dual core processor, Pentium G3258. Is 2 cores enough?

[FeilDOW]

It actually uses the cores you have, with 2 cores as strong as they are, you might have a performance hit compared to the i5 but still runs great.

So yes doom scales across many cores very well.

Probably not anymore, at least not for online. A lot of games are breaking audio and network into their own non-time critical programs so the work spreads out. Most games post 2012 are aiming for at least 3. You dont have to use more cores, as the load will stack on what ever it can, but it leaves little room for those threads to work.

i5 is 4 cores, Doom is said to use as many cores as you have available.

thanks!

Uses all my 32 cores....

Did AMD give you a unreleased cpu? lol

He maybe confusing cores with teeth. Although entirely different things, the common number here is 32.

this dude games on a xeon.........

As always, the question is not how many cores it is capable of using, but how many cores can you disable before you see any performance drop or have noticeably more hitching/stuttering?

And the answer is probably not less than 4-6 real cores.

60fps> not enough

I know for a fact that you only get 35 fps at that same spot on a G3258

Those pentiums cores aren't as powerful as an i5/i7

Same cores, same IPC. i5 has 2 more cores and i7 has hyperthreading is the only diff.

i5 3570k OCed. Just to verify, it uses all 4 cores, and doesn't favor any particular one.

I always run HWinfo 64 in the background and have many hours of records (I save them all).
It always shows that all 4 cores are used about equal. So, with 4 cores it is very well optimized.
(Both Open GL and Vulkan - same re: CPU core usage.) Impressive really.

No idea what the max is though, or if on an i7 it treats the Hyper threads (4 +4) as real cores.

Anyone know about that?

Yeah, I shouldn't have said cores. Should have said cache instead.

It's just that 2 cores of my 2600k (HT and 2 cores disabled from bios) is far more powerful than my sandy bridge pentium, even when both are running at exactly the same clockspeed.

Although, looking at the anandtech single threaded CPU benches for G3258 vs. 4770K, the difference is not as much as I thought it would be....
