Sandy bridge or Ivy bridge

[JPMD30]

Im bulding a computer and my cpu is going to be a Intel cor i7 and am wondering if i should get sandy bridge or ivy brige and what the difference is? thx

Umm you do know that Sandy Bridge came out 3 years ago. 2 years ago was Ivy. Last year was Haswell.

So, which to get. Sandy n Ivy are about the same. Get which is cheaper.

Ivybridge is the generation newer. If you are building new, you should go Haswell as its the newest generation.

Ivy bridge is more power efficient and has better performance than Sandy Bridge.
Haswell has smaller improvements over Ivy Bridge.
Sandy Bridge CPUs have been phased out and few are for sale any more.

Sandy Bridge runs cooler and overclocks better than Ivy Bridge. The choice is really : Sandy Bridge or Haswell?

Well that is true, but Ivy is still faster than Sandy at the same clock speed.


I would only go for a Sandy or Ivy if there was a very good discount.

Ivy Bridge uses less power and produces less heat than Sandy Bridge due to the move from 32nm to 22nm lithography.
Haswell introduces architecture changes that limit overclocking compared to Ivy Bridge.

It's funny that we (both owners of Sandy Bridge CPUs) are commenting on this. I chose Sandy over Ivy cuz of overclocking capabilities n temps.

Yes, Sandy @ 4.3GHz = Ivy @ 4.2GHz. However, most overclockers can easily reach 4.4GHz on Sandy whereas Ivy is lucky to get 4.2Ghz.

I bought my CPU 2 months after Ivy Bridge came out and saw how bad it was.

Yup Im well pleased with my 2500k, bought it when they were released and its still great! The main problem with Ivy, was that they used TIM rather than solder for the heatspreader.

Im pretty sure I could hit 4.8-5Ghz on mine if I wanted, but I managed to get 4.6 with the voltage at around 1.26 and the temps never go above about 48'c in gaming, so havent seen the need yet

@RobCrezz. You got some extreme cooling and really good mobo...you should run this at 4.8GHz even if voltage hits 1.3V.

The thing is, my cooling isnt anything too amazing. Case has 3x 140mm fans and the cpu cooler is great, but not super high end.

Yeah ill give 4.8 a go at some point, I think I might need more than 1.3v though, I seem to remember when I was doing the overclocking that past 4.6 it wanted a lot more voltage than the increments up to 4.6.

You cannot find a Sandy Bridge i7-K series today except maybe on Ebay and you'd probably pay more for it than it cost new, sure won't get one from Newegg!

Building from scratch go for the Haswell i7-4770K.

Ivy bridge is great but you have to have the cooling to overclock it into the higher multiplier ranges stably, and keep the load temperatures under control, I'm running a 3770K overclocked to 5ghz on chilled water cooling.

Most have been able to safely reach 4.2ghz ~ 4.5ghz with their 4770Ks with high end air coolers.
