hi there ive just seen an advert for the intel 2700k cpu. can anyone tell me what the point of the cpu? obviously its the K version and is unlocked but the 2600k is also unlocked and can easily be clocked to 5ghz. can this new 2700k go even further?
 
The 2700k is still only 4 cores / 8 threads but I think the OEM cpus Ocuk got it in were good clockers.
 
Most 2700K clock to higher frequencies with a lower Vcore than most 2600K. So more performance for less energy spent. That's the point :)

Of course, if your 2600K already clocks to 5 GHz or higher at decent voltages then you will not be guaranteed to do better with a 2700K. However, if your 2600K only reaches 4.6 GHz stable (or even lower) then the chances are very high that you will be able to squeeze a fair bit more perforrmance out of a 2700K.

Needless to say, it is the same as any upgrade where the only change is in the base frequency. There is no guaranttee that you will get a higher overclock or notice a significant difference at stock speeds, but in most cases (if you overclock) you will get a higher overclock at lower voltages.

It really depends on what your priorities are and how you use the processor :)
 
the only difference from the 2600k from what i can see is the core clock on the 2700k is 100mhz faster (stock) but k versions are going to be overclocked anyway? just seems pointless to manufacture this new chip. power consumption is same etc. must be some advantage?

As a rule of thumb: higher bin = higher stable clock and/or at lower volts.
 
Apparently according to Official ASUS P8P67 Series Overclocking Guide and Information

Results are representative of 100 D2 CPUs that were binned and tested for stability under load; these results will most likely represent retail CPUs.
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)

Most 2600K's can not do 5Ghz stable, not sure where you got that idea from.
Sure you can up the volts, run superpi and grab a screenie at 5Ghz but that is not in any way stable 24/7.

I would hazard a guess that 4.5Ghz to 4.7Ghz is where most folks settle.

The 2700K's clock a little better at lower vcore, so a reduction in thermal output and a good chance of increasing the stable 24/7 speed over the 2600k of 100Mhz-200Mhz.

There were a few cherry chips floating around at SB launch time and it is these chips that folks were sharing amongst each other creating the false impression that all SB's would be as capable.

Finding a linx/IBT stable 5Ghz SB chip is hard.
Many people will go through dozens of chips to find one.
Constantly buying/selling and RMAing till they get one.

Those numbers are much more like I would expect. Which I suggests that 98% (or more) cannot easily be clocked to 5GHz (stably).

Of course I may have misunderstood and the OP may be referring to their own specific 2600K. If the OP does have a 2600K that can easily clock to 5GHz then I can understand why they can't see the point of a 2700K personally. I'm still of the opinion though that 2700Ks were intended as an upgrade path for 2600K owners.
