These were done on custom water though with all of them above 1.3v which I don't consider a dangerous amount of voltage. All those chips are still running today and have been since 2013 at those speeds.
My 4770k couldn't hold 4.6 until I delidded it, then it was just like your second. It could bench up to 4.9 but that was hard on it. Living in my htpc in the living room right now, undervolted because on a h81.

SL=KL=CL
BW... slow for most tasks except games that can leverage the L4 cache
HW=DC

Almost no performance differences generation to generation for many years now. If AMD didn't launch Ryzen Intel would still be selling KL and wouldn't even bother with CL having 6 cores.
still there are games which shows difference at 1440,few but there are, when paired with a high emd GPU ,but those games are RTS biggrin.gif
Wanted: [WTB] GPU upgrade
$210 (USD) or best offer

Not surprising one bit. 4790K is still a beast.
post #26 of 84
Yup, 4790k will be in my rig for a bit...this cpu is the least of my worries at 4k.

Is there any raeson nobody do a 5820k vs 8700k and RAM at the same speed to get the real difference between Haswell vs Skylake Coffe Lake?

Good read. There are improvements, but it looks more like the faster RAM makes a bigger difference rather than the higher clock speeds here. Perhaps buying the fastest DDR3 you can effectively use would be a more worthwhile upgrade?

Actually kinda curious to see if that would keep your PC relevant. biggrin.gif

You've got me beat. Just read how to enable sli on that.

But that really isn't a cpu bench, look how low my usage was on my leakier chip.
post #30 of 84
im still using my 4770k 4.3ghz OC @1.15v 24/7. All games are still playing perfectly.

I will upgrade when DDR 4 prices come down a bit. Probably around Zen + or Zen 2. Next cpu will be at least 6 cores.
