Non k processors difference.

[Degraximus]

Hello forum. What's the difference between the slowest and the fastest i5 (of the same gen)? Is it just the GHz? Or are there also more features? And one more thing. If I bought the i5 3330 and the i5 3570 (non k) would they OC about the same?

 

EDIT: I don't really want a big OC. I don't even know whether I'll ever even bother with it. It's just informational.

Uhh... You can't overclock non K cpu's because the cpu is locked.

[Fulgrim]

Non-K cpu's have their multiplier locked. It means lower OC capabilities.

[tek inpektor]

non-k = No overclocking. No overclocking=average PC that your granny would use.

[JoshK]

K= No overclock. So if you wanna overclock go with K series or X series

[Mooshi]

You can overclock non K cpus, but just. Changing BLK from 100 will, but you shouldn't really raise that up much at all with new Intel chips.

 

If you don't plan to overclock at all, a non-K unit is fine. Otherwise, you're buying a gimped chip that has no potential.

[Nico123473]

with a k processor you will get more and better overclocking

You can OC them. Only the multiplier is locked you can still raise the FBS.

The K one is two K's away from a PR catastrophe. 

Also unlocked multiplier.

A little FYI for you guys, non-K CPU's can still be overclocked, but very slightly or else it'll become unstable.

Not enough to make a performance difference...unless you get extremely lucky with an uber-stable CPU.

Well you can technically overclock them a bit by adjusting the turbo bin settings in the bios, but its not much (can only adjust turbo to up to 400mhz above stock turbo settings)

[Sauron]

You CAN overclock non-k cpus even by using the multiplier, however it is locked at a lower value than the k series (normally the max a non-k cpu will do is 42x compared to the 59x you can reach on a k, a bit more if you get a lucky chip); after than you need to change the core clock but it's really not worth it, at that point you really should get a k. That is the main difference. With the haswell refresh some of the k cpus are actually clocked higher than non-k ones even at stock, so there's that.

[Cokeman]

Always get K cpus

Well i know that but i'm saying you can't oc because the cpu is mutiplier locked.

Ok so it's pointless to bother with that. What about the other part of my question? "What's the difference between the slowest and the fastest i5 (of the same gen)? Is it just the GHz?"

It's just the GHz if it's the same gen.

Well you also get a xeon instead. You can't overclock it but it has hyper threading. http://www.newegg.com/Product/Product.aspx?Item=N82E16819117316 But the difference is the low and high is GHZ

[patrickjp93]

k-series also disable a lot of features useful to programmers such as virtualization support, instruction set extensions, and security like vPro.

You can overclock a xeon, just not as much http://www.tomshardware.com/reviews/xeon-e5620-overclocking-westmere-ep,2767-2.html

Sometimes it's cache too and some of the lower end i5s sometimes have 2 cores with ht, but it's just a couple of them.
