What's the difference between these CPUs?

What's the difference between the Intel Core i5 4670K and the Intel Core i5 3570K ?

Is the difference noticeable between the 2 during gaming ? I always oc the corei5 to say 4.01 ghz.

ewok93 · Nov 12, 2013

There's really no difference in performance, and it's not worth spending money to switch.

Also , are those 2 CPUs i mentioned far better than the Intel Core i5 760 ?

JOOK-D · Nov 12, 2013

Yes they're better; newer architecture, faster and unlocked. The 760 is fine though. If you have the 760 I see no reason to change. Gaming is mostly dependent on the graphics card anyway.

Also , are those 2 CPUs i mentioned far better than the Intel Core i5 760 ?

Yes they are.

The 4670k is the newest(4th) generation. It's 5-10% more powerful and slightly more efficient than the 3570k.

The 3570k is still better than 90% of the other processors out there. It's only 18 months old.

CTurbo · Nov 12, 2013

There will not be a noticeable difference in gaming between the two. There would be a huge noticeable increase over the i5 760.

Also, none of these three processors share the same motherboard.

Do you like this combo ?

Intel Core i7-3770 3.40GHz and B75 Pro3 motherboard.

CTurbo · Nov 12, 2013

Yes that would be a pretty fast combo. What is it for? If it is just for gaming, get one of the i5s.

CTurbo :

Just for gaming. I was a bit worried about that mobo. Is it good ?

CTurbo · Nov 12, 2013

B75 is fine, but you cannot overclock on it. If you get a 3570k or 4670k, you need a Z77 or Z87 motherboard. Don't pay the extra money for a k-model i5 if you don't intend on overclocking.

dazkyl · Nov 12, 2013

CTurbo :

Well , i intend to overclock to the max . So Z-87 and core i5 4670k is the way to go ? Whats the maximum overclock you can get on that i5 with that mobo ?

JOOK-D · Nov 12, 2013

Depends on your room temperature and your heatsink, as well as the quality of the chip you receive. Get an aftermarket cpu cooler. You will be able to OC higher on liquid cooling (more expensive) but air cooling is cheap and effective.

CTurbo · Nov 12, 2013

Yes Z87 + 4670k is the way to go for sure!

My cpu cooler is the coolermaster v6 and case is cm storm stryker with a 200mm top fan , 1 140mm rear fan , 2 120mm bottom fans and 2 120mm side fans.

Overclocks are generally dependent on the "CPU lottery" where some CPUs overclock better than others. In general, people have experienced lower overclocks with Haswell generation CPUS (i5-4670k) vs Ivy Bridge CPUs (i5-3570k). Both generations can typically be OC'ed to 4.2GHz (there have exceptions for both though). But it appears the percentage of Haswell CPU capable of being overclocked beyond 4.2GHz is lower than Ivy Bridge CPUs. That's not to say a i5-4670k cannot be overclocked to 4.7GHz. They can, but fewer of them can reach that clockspeed vs. the i5-3570k.

In term of average performance increase over the generations:

2nd gen Sandy Bridge > 1st gen by 12%
3rd gen Ivy Bridge > 2nd gen by 6%
4th gen Haswell > 3rd gen by 6%

So basically assuming 1st gen, 3rd gen & 4th gen Intel CPUs are clocked at the same speed; Ivy Bridge will provide about a 19% overall increase in performance, and Haswell will provide about a 26% overall increase in performance.

Lastly, no more socket 1155 core i5 CPUs will ever be manufactured. However, Intel intends to release the Broadwell generation (5th gen) socket 1150 CPUs (same as Haswell) about 1 year from now so, potentially there is an upgrade path. But Broadwell is more of a refinement of Haswell than anything else. The manufacturing process will shrink from 22nm to 14nm, power consumption will be reduced, and the iGPU performance has been speculated to increase by (30% - 40%). No word on CPU performance, so probably another small 6% increase in performance.

The expectations is that Skylake (2015; a totally new CPU architecture and socket) will return to double digit % increases. However, that likely depends on how close/distant AMD's CPU performance will be.

So with my current cooling and cpu cooler , i can reach 4.2ghz with quite cool temps on the ''Intel Core i5 4670K'' and ''Asus Z87-Plus'' , right ?

CTurbo · Nov 12, 2013

Yes 4.2ghz would be easy

jaguarskx · Nov 12, 2013

dazkyl :

As stated, yes. But I have also mentioned that there have been exceptions to the norm where the i5-3570k/4670k could not be OC'ed to 4.2GHz. Unlikely, but still possible.
