Core i7 6700 vs de-lidded 6700K

I recently had to return a Clevo P775DM3 due to several issues, one of which was thermal throttling. While undervolting was possible, the system was unstable if I did so. It was probably a bad CPU and as such, I'm looking to try again because I like the form factor versus the P870DM3.

This brings me to the CPU again. I have no desire to overclock but would like something to get me through the next 3 years or thereabouts. I like that the non-K i7 6700 has a 65W TDP which should all but eliminate any possibility of thermal throttling. It's also cheaper and I wouldn't have to mess around with voltages and so forth.

But for performance, longevity, and resale, there's the 6700K again. This time, de-lidded and pasted with Coollaboratory compound. Again, I'm more concerned with thermal throttling and noise than with any overclocking potential. Plus, I may still have to tweak around with voltages, which I would really prefer not to have to do.

Input is appreciated.

 

Definitely go for the 6700k and delid it. You'll be happy you did once once you see how cool your temps are. You might even surprise yourself and have quite abit of head room since you're planning to use CLU.
It's not worth cheaping out and gimping such an awesome system with a non-K part.

First system I had was a bare-bone Clevo P870DM-G with a 6700K that couldn't even run stable at 4.2 GHz x4 (on all cores that is). Next system which was a Eurocom Sky X9 also had a 6700K, this time a bit better, it was able to do 4.3 GHz stable.

I have seen many users here complain about high temps even at stock speeds. The 6700K is a hit or miss, 50-50 chance to get a good one. Even if you don't want to overclock, spending a bit more to get a Silicon Lottery one ensures your CPU will run cooler overclocked or not. Giving you better thermals and longevity since the CPU won't be running hot constantly.

This Silicon Lottery CPU I got (rated to run @4.8GHz in a desktop) can run @ 4.7 GHz not very stable, 4.6 GHz stable but with higher temps than I would like in a laptop for prolonged use (94C) or running super stable @ 4.5 GHz all day long with max temps of 85C no matter what I throw at it.

 

Silicon lottery CPU is greater than double the cost of the de-lidded 6700K upgrade, so it's not just "a bit" more expensive.

IMHO SL CPU's are not worth it in laptops.

 

Better just abuse the microcenter return policy and buy 6700K to delid yourself

 

Not really.

Specially since majority of the 6700k's de-lidded can easily do at least 4.5Ghz.

 

@saturnotaku add some more options to the list, just because everyone is picking the SL solution just means of the 2 options it's the best one for performance - remember performance at any cost

 

Look at the 6700K sku options at Silicon Lottery, each one gives a % of chips at each speed from the last pick.

That tells you the odds of pulling one at random on your own out of Microcenter - or from any other resellers stock.

You can still pull a gimped one, but the odds are a lot better that you won't since @Phoenix got his - he really did need to get an SL CPU then, now - not so much, but their prices have come down too.

You don't need to get the top speed SL CPU, get the next speed down from the top current offered, it's a big savings and only 100mhz

 

I'm buying the CPU from HIDevolution as part of a new build. I'm not going to install it myself.

Just de lid it yourself later on.

 

buy 10 6700K with diff batch number, OC them in your machine and see which one does the best

delid the best, install, then return the other 9

 

No.

That's essentially what Silicon Lottery does; except they sell the losers for a profit too

 

"That tells you the odds of pulling one at random on your own out of Microcenter - or from any other resellers stock."

As I said, that's pulling a random sample from the pool of available CPU's, which should follow the Silicon Lottery current %'s pretty closely, chances of getting a 4.7ghz capable CPU or better are 59%

Intel 6700K @ 4.7GHz Boxed Processor - $ 339.99
https://siliconlottery.com/collections/frontpage/products/6700k47g

"As of 5/3/16, the top 59% of tested 6700Ks were able to hit 4.7GHz or greater."

 

If your only concern is thermals, there is zero reason to get a 6700 over a 6700K. Judging by Intel's habit of throwing bad silicon into lesser SKUs, a 6700 vs. a 6700K at the exact same settings will actually run hotter. If you really want to, you can limit the 6700K to 65W, but that seems like such a waste when you can have HID delid it for a relatively low price and still have it covered under warranty. The only real valid reason to go for a 6700 over 6700K is the price.

 

Then why worry about the thermals ?

 

@saturnotaku just get an already delidded one and forget about it until your next machine.

 

Did you completely miss the part where I said I wasn't going to overclock?

This does not sound like an ethical practice to me. Why should any supplier bear the cost of another's experiment?

Buy 10 6700K with different batch numbers, OC them in your machine and see which one does the best.

Delid the best and resell the other 9 in the used market because that is what they are, used.

Yeah, I'm still trying to figure out why you are wasting our time with this thread...

If you don't care about OC, and you want to save money, then this poll and thread are a waste of everyone's time.

Buy some cheap part, and have fun

Continuing with that thought, why are you wasting time with a super OC'able laptop if you are not taking advantage of it for full performance??

Buy a nice BGA laptop that won't thermal throttle, and get a nice long warranty so you don't need to worry about fiddling with it yourself.

No fuss, no muss, no fiddling around for hours to get it cool and quiet.

You can focus on the work or play role the laptop is intended to fulfill.

You are buying a benchmarkers OC heaven laptop, for what?

It's expected to run hot and be noisy cooling it down, it's exactly the opposite of what you say you are looking for...

 

the system is there for you to abuse :^)

 

Which drives up prices for everyone. I am not impressed.

And yet here you are continuing to post in it. Now, kindly sod off back to where you came from.

 

My previous 6700K could barely do 4.3 GHz delidded with CLU as well

 

Apart from brother @Phoenix most of the 6700k guys have got 4.7ghz without any trouble. I got 4.8ghz relatively easy with a delid.

@saturnotaku

I recommend you just get a stock standard 6700k and buy a Rockit Mod delidder ($30 and full proof - see my delidding for n00bs video in the Clevo forum) and do the rest yourself.
6700k isn't worth Silicon Lottery prices in my opinion unlike X99. Especially since you're not overclocking and 6700k are binned relatively even by comparison.

If that's too much trouble see if Hidevolution will delid a standard 6700k since you're not overclocking and then you can simply enjoy the superior thermals.

 

HIDEvolution has in house delidding and they won't void the warranty if they do it

 

Beautiful, that's probably what he'd be after. Just a delid and standard K clocks.

 

Im sure we would have been able to do something about it. But im glad the SL chip worked out for you!

 

My 6700K in the desktop does 4.4Ghz easily.. probably could do more if needed...

 

@saturnotaku I recommend you just get a stock standard 6700k as @TBoneSan said. 6700 isn't an option(worse binned chip). You don't need any SL chips or delided one if you prefer to run stock clock-speed. Ask your dealer if they can tune the processor for lowest temperature with maximum stable stock clock speed before sending the laptop home to you. Then they can note down the settings used so that you can put the values in yourself if needed(if you have made a mistake and lost the settings).
