I am going to build a new pc mainly for gaming and I was really curious to know that if a Haswell chip i5 at 4.6 ghz is equal to a Ivy i5 at 4.9ghz ? If yes then they should be I think technically same in performance as:-

If a Haswell can just oc upto 4.6ghz stable , which is its max limit due to Temps and A Ivy can oc upto 4.9 ghz stable And if the performance is approximately equal then do you think It is wise to buy Haswell just for clock improvements ,new instruction sets and the Power saving states?plus I recently heard a rumour that broadwell will be coming with a new chipset that is not backwards compatible.....so what do you guys ?

NOTE : I know it all depends on the silicon lottery, but as a matter of fact ivy can oc more than Haswell (please correct me if I'am wrong) due to the fact that the voltage regulators(FIVR) are outside the CPU which gives it a little extra room for a few 100-200 MHz.

Thanks in advance :D

Intel for the most part does not build CPUs so we can overclock, they know there is a large overclocking community out here so they do provide CPUs that are unlocked so they can be overclocked.
Their main focus is on a great performing processor that will provide good performance at stock speeds and so they also are going for the lower TDP on their processors to cut down on the power requirements and usage.
Because of this each new processor release has a lower overclock ability due to the low power that the processor requires, Haswell overclocks less then Ivy Bridge which overclocks less then Sandy Bridge.

Haswell was not a big improvement over Ivy Bridge so at this point if your an overclocker then you want Ivy Bridge. The newer...

Anyone that follows overclocking benchmarks can see that an overclock while increasing performance doesn't increase it to the point where it's a must have. The last couple hundred MHz only gives you maybe 5 fps tops. In my book it's not worth stretching the processor to get that.

In gaming we all know it's all about the video card.

First of all, thanks for the great answer as I got to know a lot better about these cpu's. My final question to you is - Me being mainly a gamer and using my rig for casual video rendering and editing what would you recommend between the 4670k and the 3570k? I know the Haswell has new features but when I go to forums and see that many people are complaining about high temps and crashes, it really makes me nervous so I also want your opinion on that. ( if 4670k then I'll be using the MSI Z87 G43 mobo and if 3570k then
Asrock Z77 Extreme 4, the cooler would probably be the cooler master seidon 120m and the gpu would be the HD 7870)
I will just be aiming at 4.2ghz on both cpu's.

If your doing video rendering and editing then an i7 CPU would be good for that, however if it's just a casual thing and not all the time where you need it to get done faster then you can use an i5.
If your going to just go with 4.2ghz then I would go with the i5-4670k and I would use the dual radiator closed loop water cooler. Like one linked below.

But my but my budget is not allowing me to buy a dual radiator as they are very expensive in my country, what should I do?
And don't you think the cooler master seidon 120m should be able to OC a 'decent' 4670k to at least 4ghz?

I'm not really sure where you got this overclocking information, but with the cooling available to you and looking over where others have successfully overclocked their Ivys 4.6ghz is more the realistic fact for the Ivy, look at the results in the Intel Overclocking Club of those cooling with High End Air Coolers and CLC Water Coolers.

Is it possible to reach 4.9ghz on and Ivy STABLE with traditional cooling, Yes, however some have delidded their CPUs to accomplish it, and I don't recommend doing that, tossing a 3 year warranty out the window on a brand new CPU, is overclocking insanity IMO.

With the best traditional cooling solution you can acquire where you live 4.6ghz will probably be the best you could reach overclocking the Ivy and more than likely will be more like 4.3ghz ~ 4.5ghz.




The quality of the CPU core does play a part in overclocking that's why some buy the 3770K over the 3570K (higher clock lower voltage), even though their use of hyper threading 3770K will be seriously limited, the core was a better binned batch of silicon set aside for the higher end CPUs, but in harsh reality the major player in overclocking is cooling, the cooler you can keep it, the further you'll get with any CPU.

Of course the rest of the hardware matters as well, that CPU needs to be socketed into good overclocking motherboard surrounded by overclockable hardware as well.
