We saw some 4.5/4.6 on the 6850Ks, but everything else has capped at 4.4. Either Intel is binning the premium 6 core better this time, or it was just extremely good luck. Of course the more cores you start adding, the more difficult it is for all of the cores to clock higher. It's easier to find 6 good cores together rather than 10.
Have you gotten to your "end of week 6800K mass-checking" yet? Are you uncovering ANY 4.5ghz 6800K at all? Haven't seen any on the site. I have a custom water loop with a 480mm rad, a 420mm rad, and a 360mm rad with an EK Supremacy EVO CPU block and MCP655 pump. And i just ordered some of the new Cool Laboratory Liquid Copper TIM so my temps should be fairly better than with the H105 you guys use i assume.
Do you think that on a setup like mine that your i7 6800K "4.4ghz @ 1.344v (or less)" binned chips would be able to push 4.5ghz at a safe voltage? Hoping for 1.35v or less, 1.375v mid-tier hopes, and would probably still be "ok" with anything under 1.4v since you said earlier 1.4v shouldn't show degredation of lifespan much.
I'm wanting to hold off on pulling the trigger till i can see if you guys pull a 4.5ghz (what is the typical "voltage" bin you guys do for 4.5? I mean like how all of your 4.2 chips say 1.312v, all the 4.3's say 1.328v, and all 4.4 say 1.344v (or less) etc..) but at the same time don't want to wait too long and you guys sell out of 4.4 and never get any 4.5 lol.
Sorry for all the questions, just trying to discern what the best option is. Part of me wants to save money and just risk it with a ~$420 boxed 6800K from retail, but i'm an OC freak and since i'm selling my i7 5960X that i got for video rendering + gaming hybrid that i could get to 4.5ghz + 4.2ghz cache @ 1.28v i want to get a 6800K that will be as close in multi-thread performance as possible to a stock 5960X so i won't "miss" the 8 cores as much if you see what i mean lol.
