Do games use 8 cores?

[Stuped Bürd]

I'm thinking about upgrading my cpu. I have an AMD FX-8120 and am thinking about geting the FX-4350. The 4350 has better preformance, but it has 4 cores. Do games even use all 8 cores? Dying light for example has an 8 core listed as it's minimum AMD cpu. So would getting this quad core be a good choice?

Depends entirely on game architecture,what a given game is written to do.Some games require "affinity" to be set to run at all.So-good for some-bad for others.

Doesn't really answer my question. Would I have a problem running newer games if I get the 4350 instead of some other 8 core.

FX8 & 9 are Quad (8 modules)
FX6 is Triple (6 modules)
FX4 is Dual (4 modules)

FX8 is obvious winner against the lower ones here. How u come off thinking an FX4 or 6 could be faster, u making that up. If your FX8 is lacking in performance, then either your Motherboard is not good enough, or you doing something wrong.

As long as you have a good motherboard and PSU I would simply suggest to buy a high performance 3rd party CPU cooler ($20 minimum on sale, $30 and up regular) with at least 4 heatpipes or better 6. Then do a mild overclock to the same speed as the FX 4350.

A liquid cooler is also a option.

Most games in the future will use 8 cores. Many or even most games already do.

bad is slightly off
fx8-9 = 4 modules
fx6 = 3 modules
fx4 = 2 modules
each module = 2 cores, 1 fpu, and l2 cache bank

if you want an older cpu with better core perfromacne go back to a pii x6

its clocked 33% lower, but its performance is only 6% slower
it can oc by 10-15% easily with a good board and cooling

Ok yea, but what I was saying, they aren't 8 cores.
FX8 is still a Quad core performance, cause of how the modules work.

Put a good hsf on the FX8120 and overclock it. Whatever the GPU is is a deciding factor also.

To the 4350 It'd be like a sidegrade if you overclock the 8120.

More reading ^.

Ps keep what you got provided you overclock it.

overclocking fx8 also needs a good board
4+1 with vrm heatsinks or better

[Bad 💀 Motha]

Typically u will want 8+2 phase for FX8

I'm using the sabbertooth 990fx as my motherboard. I normally have cpu clocked to 3.8GHz but now that it's getting summer I've clocked it back down to 3.1GHz which is proabably why I'm noticing worse performance on new games.

Well ya a cpu 700mhz drop would show, your mobo is good but what cpu cooler and gpu have you got?

[Azza ☠]

When doing game development - in order to make use of a CPU core, you need to write multi-thread coding. This gets more complex to optimize the more threads you use.

The Operating System will take up one core at least - so don't forget that.

A lot of single player games don't have 8 threads or anywhere approaching that. The vast majority of games today use 1 or 2 cores, with some using 3 or 4.

I've personally never coded a game will more than 2 threads, apps on the otherhand perhaps would be more logical to make better use of them all, but still complex to achieve. Most AMD cores end up simply sitting there idle, only kicking in with apps / multi-tasking, and not on games. This is why many perfer Intel over AMD for gaming purposes these days - it focuses on removing bottlenecks from the motherboard, rather than just the CPU being a beast.

Battle Field 4 in multiplayer with 64 players on the map could make use of a full 6 cores. Windows / Multi-Tasking using another core, therefore it will be maxing out most by that point of time. So it can depend on the game, but still rather currently limited.

The "Cryengine 3" game development software with Crysis 3 is capable of using 8 core processors well, and it shows. That would make some good use of the AMD multiple cores.

I have some corisar h cooler. I think it's an h10. My gpu is an r9 270x.

The majority of the games out there use only up to 4 cores, there is still some games that rarely makes the use of a 6 core CPU and even that it's only beneficial to the perceived performance in a handful of a few demanding scenarios, there is actually a bit of games that makes the use of more than 8 threads, but who cares because the game won't require that much horsepower on the current generation of gaming unless we are talking about an AMD CPU which could benefit greatly from the extra utilization of it's cores if your target frame rate is more than 60FPS, other than that it would not matter much.

h100 you mean?

Anyways just overclock your CPU.

You can disable 2 modules (4 cores) and clock the remaining 4 even higher if you only want to use a quadcore for whatever reason or think you can get a higher overclock that way.
