Starting to doubt the power of the 6700K

[Tyrosen]

I was really hyped to see Skylake come out last year, and was really happy when it went mainsteam. But then I saw this review on Youtube on how terrible it was, and how we should stick to Haswell, because it made minimal impact to performance, then buying the latest i7 Haswell. I always thought the 6700K was good and reliable for overclocking, as there is really not that big of a chance hitting the low spectrum of the silicon lot. Any comments on this?

[TheRedViper]

The i7-6700k is a good CPU for OC Idk what you're talking about. 

[Misanthrope]

I think the non-k is a better choice. You get max boost of 4.0ghz anyway but at a lower TDP. Aggressive overclockers are better off trying those on the x99 platform instead. But well if people are happy with paying a little bit more on the chip and a lot more on the cooling solution and motherboard to get 5 to 10% of extra performance by all means.

[Matias_Chambers]

Where did you hear this? The performance difference from generation to generation is always small. The 6700K is a better overclocker. You can use higher voltages and stuff.

Skylake isn't that big of an improvement over Haswell refresh, that is correct. But I wouldn't buy any skylake CPU because of this:

http://www.pcworld.com/article/3021023/hardware/how-to-test-your-pc-for-the-skylake-bug.html Basically this bug can only be fixed by updating the BIOS, leaving non-techies systems in limbo on why their shit is crashing. Yay Intel!

The 6700k is the BEST option for a high end CPU in the gaming market, it's even marketed as a "gaming processor"

At this point, to buy a Haswell CPU is kind of pointless, unless you're going extremely high-end with haswell-e, haswell still uses DDR3 which belongs no where in 2016 + the skylake platform and ESPECIALLY the 6700k allows for EXCELLENT overclocking to at least 4.5ghz

 

 

GO SKYLAKE

 

btw This is coming from somebody with a 6950X

[airdeano]

well from platform to platform (tick-tock) the newer generation is prolly 8-10% better in power output, lower energy usage, and new technologies.

 

jumping from haswell to skylake one should not have expected monstrous performance gains.

True, but there is always googling, "How to refresh/update the BIOS"

I've got a 5ghz 6700k.

 

Sure I got lucky, but guess what, I don't really care. It's at 5ghz all day every day. Does it perform better than Haswell? I don't know, but my 6700k has done everything I've asked it to do. 

 

It's a good CPU that I bought to do what I needed it to do.

In some games even the Ivy Bridge 2600k comes close to the 6700k in like 2-3 fps at 1080p and 1440p,CPU's are going slow compared to GPU's

4.5ghz on a 6700k is the starting point for an OC. If you bought a 6700k and OC'd it there, you'd be leaving performance on the table.

Now that's the lottery

Heck the difference between haswell and skylake averages less than that at around 5% (3-8% from what I've seen depending on the application of course)

[Tyrosen]

So Kaby Lake is coming soon, heard it was just small slight changes to Skylake

Bought a 6700k from Microcenter. It was dead in the box, couldn't get it to work at all. 

 

RMA'd it with Intel and got this CPU from them. 5ghz at 1.39V in the bios. 

 

So if anything, Intel sent me a CPU that was good, and it just happened to be a REALLY good one.

I've heard people getting crazy numbers like 5.5GHz with 1.35V before

I highly doubt that, 5Ghz seems to be the most for standard cooling solutions that I've seen (aka not liquid nitrogen) and generally it's higher than 1.35V since skylake can go up to 1.45 without issue.

 

If you want to know more about skylake overclocking @Lays would be the person to ask since I'm just going by what I've seen

I'm just using a H100, it's not delidded, nothing special.

 

My h100 is on a push pull with EK fans in a CM Mastercase Pro 5 with 3 AF140 intake fans and 1 AF140 exhaust. 

30-35 idle temps, 60-65 gaming temps, 80 on a 4+ hr Prime 95 run.

 

I've also got 2 Strix 1080's in the same case on a Hero Alpha motherboard with 32GB of Gskill DDR4 @ 2800mhz.

 

I got lucky. It's a good OC'er but it's at it's knife's edge. But at least when it does die, it'll go out at 5ghz.

Are you from an alternate dimension? That's ln2 cooling territory.

I remember it was watercooling, The guy used a peltier

5 Ghz isn't standard whatsoever, according to the OCN skylake oc thread, only like 15% of 6700k can do 4.8 or higher, and they have an extremely  large sample size from the community submissions.

So to give out some numbers. Alot of you are knowing siliconlottery.com, 

 

They put statistics on there site which are showing how many CPU's were able to archieve there overclocks on a Asus Maximus VIII Hero board passing ROG Realbench for 1hour.

 

Intel 6700k @4,5GHZ - 100%

Intel 6700k @4,6GHZ - 97% @1.392V CPU VCORE (Or less)

Intel 6700k @4,7GHZ - 59% @1.408V CPU VCORE (Or less)

Intel 6700k @4,8GHZ - 17% @1.424V CPU VCORE (Or less)

Intel 6700k @4,9GHZ OR Higher - 2% @1.44V CPU VCORE

 

For me these numbers are quite interessting, because they really test a ton of CPU's to sell them for more money. Unfortunately they dont show statistics for the 4790k Processors.

$600 for an i7-6700K @ 4.9GHz? Not worth it

[AshleyAshes]

So in conclusion, no top end intel CPU has ever been so improved that they are worth throwing the most recent previous generation machine into the garbage and building a new machine.  ...None of this is shocking news.
