Are 2600k better bins vs 2500k

[tijag]

I'm sorta kicking around getting a new computer to replace a surprisingly still workable E8400 box.

As I look at the difference between the 2500k and the 2600k, I'm very curious to know if as a general rule, the 2600k has better overclocking headroom/runs at higher clocks with lower voltages than the 2500k.

Since I use computers for at least 3 years, the HT of the 2600k is somewhat interesting, as I imagine I'll get some benefit out of that by 2013/2014, however, I'm primarily interested in whether or not the 2500k has the exact same OC potential as the 2600k.

Is there any evidence to support that near 5ghz clocks are easier to achieve on the 2600k?

short but quick answer..

Yes, but ultimately still YMMV.

Meaning yes they are better bin'd @ stock.. but once you factor in OC, there is always a chance of a cherry in the pile of sour apples.

From what I've seen these processors are all hitting the same wall which simply means binning isn't a huge issue just yet. Once you start seeing Intel scale their chips or come out with a different stepping you might finally stand to gain from a binning perspective. Even then we're talking about minuscule advantages at best but as of right now you'll end up in the same ballpark no matter which one you choose.

Just how far that added cache and HT will take you is anyone's guess, though I'd certainly say the numbers suggest a 2600k is not worth a $100 dollar premium. That will likely hold true in the later part of these CPU's life cycle.

I got my 2500k to 4.4 with almost no effort. I can probably go higher.

Saying that if you are going to use this CPU for 3+ years then I'd probably go for the 2600k

Should take you til 2017 1nm fab.

Binned based on what criteria? Are there really 2500k chips that can't handle 2600k clocks? Or are they binned according to voltage requirements/leakage?

Most SNB chips seem to clock well, the 2500k's may be binned as such because of problems with their HT, but at the minute it "seems" that Intel have more than enough capacity to make 2600k's and just bin to fulfil demand.

The 2500k has no ht or added stress on them so everyone getting high clocks with them.
The 2600k have to be better because there getting good clocks with the added strain from ht.
If you took 2600k shut off the ht you should get a higher oc with less voltage then a 2500k.
On i7-900s it is so much easyier oc if ht is off but since you paid for it everyone leaves it on.

This statement might seem to make sense intuitively, but do you have any evidence or sample size to support this?

You know if i could find out how they bin the cpu's, i would be getting super cherry's all the time.

But intel still keeps this a secret.
But they do bin.. i can tell you for a fact they do.

it has to do with operation threshold in there tests.
They have a grade scale where if a chip can score X on there scale, its moved to X.. and if its cores Y, its moved to Y, and consumers get all Z's.

But the thing is.. we dont know how they bin.. so its not fair to say, they bin on OC potential.. for all we know, they could bin on lower voltage.. or what on how leaky the cpu maybe... ect...

There is nothing to back it up.
Because as i said, you will always find cherry's in a pile of sour apples.
