Sandy, Ivy, or Haswell?

[mitchpman13]

Well sad to say my old CPU (2600k) died out on me.

 

Still looking into the i7 processors. Figure I do a system upgrade for the cpu and mobo. I figure I ask comparing the 2700k, 3770k, and 4770k. What are the pros and cons to each one? Which runs the fastest, better OC, lower temps, etc. Just want to get a general idea of how they all run.

Ivy is much better for temps and for OCing. Haswell is more power efficient.

[Flyguygamer]

About the same, the newer ones will perform better per clock while the older will overclock better (silicon lottery permitting). It is up to you, Personally I would go 3770k or 4770k.

[WoodenMarker]

The 4770k is fastest followed by 3770k and lastly by the 2700k. In the same order, the cpus will have increasingly higher average oc's but the higher ipc for the newer architectures make up for that.

My condolences :'(

 

 

Always go for the newest, Haswell.

 

Haswell is a new architecture and the 4770k is better than it's predecessors (2770k,3770k) performance wise. Also LGA1155 is a dead socket so if ever you want to upgrade, with LGA1150 you can.

4770k: most powerful, new socket, runs hotter which limits OCing.

3770k: if you have a Z77 board get this, more powerful then old cpu, OC well.

2770k: if your not using a Z77 board and don't want to buy a new one get this, least powerful of the 3, (about 20% difference between this and 4770k) BUT its the best OCer and runs the coolest.

sandy is the best for temps.

 

Op get a 4770k or wait for the refresh or wait for broadwell.

ivy oc's well however haswell is more power efficient. But to me the the deal breaker is that z87 mobos are much better feature wise and im pretty sure that oc ability is not as dependent on the motherboard for z87 chips however having a good power stage is important.

Right now the i7-4770K is less expensive than the other two. The difference isn't enough for a new motherboard, but it does help. Given that Haswell is clock for clock more powerful. And given that contrary to popular opinion, it is not a terrible overclocking chip - just not as good as the others, I'd suggest going with a 4770K and z87 motherboard.

I agree that the Z87 boards have good features but the older CPUs clock better. Some Haswells wont go above 4.3 Ghz and have temps.

 

I would wait until Haswell-E and see what type of performance and PCI-E lanes you get with it, if you can wait that long. 

 

If not and you're only running 1 GPU then Z87. If you plan to run two cards then X79, if on a budget then a 8350.

Thanks everone for all the info.

70% of i7-4770K will oc to 4.3GHz

30% will oc to 4.6GHz

20% will oc to 4.7GHz

 

If the principal reason one is purchasing a cpu is to overclock, by all means stay with an older architecture.

 

As far as I'm aware gaming loads on dual CF/SLI PCIe 3.0 x8 do not saturate the lanes. If you have a link to contradictory data I'd be interested in seeing it.

[Bloodyvalley]

Guys, Haswell does not OC high but when you do OC it performs very well.

 

For example, a 4.3ghz Haswell CPU will beat it's IB/SB equivalent at the same clock speed.

Keep your motherboard, and get a 2700k. It is the exact same thing as the 2600k, but without integrated graphics, and you don't need to change your mobo

Nope, nothing to contradict that info. I am thinking more long term since he has had his rig for a while. GPU speed has picked up a far bit as of late and Im curious if that trend will continue.

This. As long as its a 4.8ghz+ then you'll be faster than haswells at 4.4ghz.  Its much cheaper to keep your current board then buy both things new

I just got my i7 4770k, i have not OCed yet but i will in a month or two, and i must say i am in love with this CPU, i am sad to hear about your 2600k, that was an amazing chip.

If you do not care about PCIe 3, having all SATA ports SATA III ( remember that the real MoBO bandwidth is around 1.4 GB/s ), native USB 3, then by all means stay with your platform, a 2700k should be quite a bit cheaper than a 4770k.

If you want the new features, go with the haswell platform, clock-for-clock it is faster, it is more efficient, and offers all of the features i mentioned above.

 

Haswell runs as hot as the 1st generation of power hungry 1366 i7's so you will need a a good heatsink for overclocks. 

I am sure you are aware that overclocking is not guarantee, so you might get bad overclocks on any platform.

the 70% bad overclockers is exaggerated, but do note: an average haswell chip will go up to 4.3, a better chip will go up to 4.6, and a golden chip will go over that ( consider this is all up to 1.35v, and even then you will need a monster cooler for that )

 

Ivy is a good middle ground platform but it runs hot as well. 

I still use a stock heatsink since i don't overclock ( yet ), but my mobo ( Asus maximus VI hero ) lets all cores run at max boost ( 3.9 on all cores, instead of 3.7 ) so i usually get better results than other 4770k's ( only slight advantage ), i can report that this chip will get to 85 under max load with ease, so yeah, haswell gets really hot.

 

I can only advise you to take all our comments into consideration and decide how much money are you willing to spend. Hope this helps!!!
