Basic Skylake 6700K Overclocking review and performance.

8 Pack said:
All 5820k I recently tried can do 4.2 at 1.2 on basic air. For 4.5+ in general u need water but the IHS is soldered so no delid.

The maximum, minimum frame rates 4.2 5820 vs 4.5 6700 was within 2fps when I tried on bf4 and crysis 3 with 970 at 1080p

I have delided about ten of these 6700k CPU. The paste in my opinion is simply awful. On ln2 pot temp -186 I have seen a CPU throttle at 100+ with 1.65v. Really junk TIM.

So delidding these chips is a must then 8pack?

I think when i invest in skylake and try to overclock if i find i have a decent chip which can get to 4.5 easily enough i will delidd it!

The problem is the IPC increase is not massive,and until we get more user testing the extra OC headroom is not a given,especially with the fact the Core i7 5820K uses solder and has a larger die meaning cooling should be easier.

You are literally just splunging money for a two year upgrade and I would garner that the X99 setup will hold its value better anyway - remember it not only appeals to highend gamers but a whole lot of people doing productivity stuff too.

The problem is it isn't even £100 though unless you go for a very basic Z170 board,and even the cheaper X99 boards will be built to a higher standard anyway than a cheap Z170 board.

Something like a Gigabyte GA-X99-SLI is only realistically £40 to £50 than a equivalent Z170 Gigabyte board.

Plus there is hardly a price difference between a Core i7 6700K and a Core i7 5820K currently with a number of retailers having the Core i7 5820K at a lower price.

So,at this point I see no point in going for the Core i7 6700K unless you are doing a small mini-ITX build and even then the X99 mini-ITX motherboards are close in price to the only Z170 one which is listed ATM.

At least the Core i5 6600K is under £200,and makes the Core i7 6700K very overpriced indeed.

£100 more for HT is getting silly now.

Edit!!

Also remember that Skylake has no FIVR so the motherboard is going to be more important again when overclocking too.

But aren't cheaper x99 boards going to hold you back more when overclocking is in mind? Yea i know the 5820k is soldered and has a bigger die so more surface area means easier to cool! But from what ive seen the 8520k don't seem to overclock to that nice 4.5Ghz easily like a 3770k or these skylake chips can. 8pack confirmed all his chips did 4.5 on stock volts so seems like the norm!

So 3-5% weaker IPC and less overclock (possibility) ability puts me off abit :(

i know it has 2 more cores and means 4 more threads but there's not even a handful of games which are utilising more than 4 cores. One that comes to mind is GTA. I know this will change with DX12 but we still have to wait for this too.

I just don't want to side grade from my 4.2Ghz 3570k is all lol! Want to get at least a bump in performance!
 
Well tbh, skylake isn't going to be a massive upgrade from your 3570k. Particularly for gaming, I had that same CPU before moving to a 3770k. Then switched to Z87 with a 4770k followed on by a 4790k. For single card gaming all of these chips were pretty much the same. Only originally replaced the i5 with the Ivybridge i7 as I was running sli and the ht helped in a few games.

Thanks for the reply :)

I know were talking 15% - 17% performance increase at best from a 3570k with OC in mind too! but i can't get my 3570k past 4.2 without silly volts which could be from a bad chip or my £80 motherboard which doesn't provide much OC room!

i'm confident that i can get a better OC from these skylake chips from going on what 8pack has said! So with a decent Mobo and with the better IPC which stock for stock should be at at least 10% by now, with overclocking to 4.5 which 8pack has done on stock volts should be up there at 15% increase combined with 4 extra threads! Seems like a nice little jump in future proofing and performance. I could get even high OC for all i know but i think 4.5 is realistic.

I'm also needing more than two sata 6Gb/s ports and im also wanting to jump on the m2.sata SSD as well. So need to upgrade to get these features.

Myself, I'm probably gonna move over to X99. The extra cores may come in useful and it should run cooler. Got a 4790k which I run daily at 4.7ghz. But it does hit the mid 70's in games. From reading 8 Packs review in the op, a 5820k at 4.2 is very similar to a 6700k at 4.5. Anything else I get higher would be a bonus.

Really? a 8520k at 4.2 is similar to a 6700k at 4.5? You just tickled me into the other direction now lol.

crap i'm going to have to put more thought into this now!

Wouldn't you be stepping down in performance terms though going from your 4.7Ghz 4790k to a 4.2Ghz 5820k? (unless your confident you can OC the 8520k more?)

a 6700k at 4.5Ghz should be equivalent to a 4.7Ghz 4790k i imagine?



I'm confused lol.
 
For me it would be a sidegrade with a 4.2ghz 5820k, but as mentioned. How useful the extra two cores would be remains to be seen. The 6700k at 4.5 does look very similar in results to what I get on the 4790k at 4.7, (1 300v). Could get 4.8 but then temps become a limiting factor.
 
My 4770k is capable of 4.8Ghz but I cba with temps this weather so run it at 4.3 stock volts. Can't really tell the difference, couple more mins when encoding DVD's and that's it :D

It does seem a good point! and if the 5820k does OC past 4.2 then its just as good! But running cooler and two more cores 4 threads does sound appealing. Ahh decisions :( maybe i should focus on my GFX card upgrade first lol. 980Ti or Fury X lol. Off to graphics card section i go...

Unless you are going mini-ITX where the X99 mini-ITX motherboards are very expensive,

Motherboards? As in more than one? There's only one mini-itx motherboard isn't there, and it's an ASrock one with a lot of compromises that take away the point of going X99.

To be honest going down the X99 route and buying an Mini-ITX is pointless, which is probably why most of the manufacturers haven't bothered making motherboards for it.

The market for X99 is already small, the demand for X99 mini-itx is miniscule.

People still encode DVDs? With 4-5TB HDDs being so cheap, might as well just remux and retain 100% quality.

Unlike with Haswell,there is no FIVR,so Skylake is going to be more motherboard dependent than Haswell.

Plus,TBH people obssessing over like 10% to 15% more ST performance is not going to add much over 4 years,whereas 50% extra threads will make more of a difference - remember all the bumpf from Intel over DX12 and improved multi-threading.

But thats the thing - I wouldn't be upgrading for a measly 15% maybe 20% improvement in ST performance anyway.

I would rather spend it on a graphics card upgrade!

Unless you are rocking a high end card,most games are still bottlenecked by your card.

The extra bandwidth and L3 cache over Haswell might be helping Haswell-E in some cases.

15% ST is way out in my testing. Not even 10% for me.

For gamers of course high quality card most important. For Gamers who do other things also add X99 and be done!!!
