I spotted as much as a 50+ min fps gap between Ryzen and this 8700k. Thats a lightyear away really. AMD has work to do.

Mediocre mins are ryzens big downside You'll notice them with a 1060 at 1080p and a 1080 at 1440p.

People should try educate themselves for the reasons of using TIM. So many ignorant people see something online and repeated it without knowing why and they try to pretend to be smart. omg
There's only two reasons to use TIM over solder between the die and the IHS:
1) It's cheaper
2) The die needs to be big enough to not have to worry about it cracking after applying the solder to it

You know where neither of those reasons matter when it comes to CPUs? In the HEDT market where you pay a huge premium for the number of cores and the MOBO platform itself, negating reasons 1 and 2 as the price doesn't matter and the die is more than large enough to handle the solder.

You know where Intel still uses TIM instead of solder anyways? In their HEDT chips.

You must be blind since there's 30 FPS difference and it's just one game that sold quite badly for Ubisoft. Also it's one of the most boring games that I've played to be honest...

Only 20% higher power consumption for 50% more cores is quite impressive.

2) The die needs to be big enough to not have to worry about it cracking after applying the solder to it
Its just the cost as they managed to solder a 81mm2 Clarkdale while Skylake for example is 122mm2.

I would argue that there isn't a place in the private sector where "price doesn't matter". A place where the price doesn't matter would be something like a governmental organization, like the military. In the private sector price always matters on every level. It might be cheaper to use TIM instead of solder but I would argue that it is not that much cheaper so as to risk the quality of their product. And also Intel says that overclocking is something you do at your own risk. Just because you want to overclock that doesn't mean that Intel has to pay for it, that is something you have to pay for.

Welp there goes the entire Ryzen lineup.
That is to be seen when the entire Coffee lake lineup is released, all the way from the Celerons to the i5's. Personally I'm mostly interested in the low end i3s and the Pentiums. The G4560 needs to exist.

This chip is a true monster...

but so many TIM defenders in this thread.

I don't need to be a software UX/UC designer to tell you that Windows 8 sucks(ed), and I don't need to be a specialist engineer to tell you that TIM sucks (it's not even good TIM, if you replace it with one of the top 10 TIMS you still get a temp drop).

Please stop assuming that Intel did this for some genius reason that no one here understands. They did it because the chips are easier and cheaper to manufacture and they probably made the decision to do this well before there was any competition on the market.

Of course Der8auer loves it - enthusiasts who want to push their chips are buying his delidding tool like hotcakes - I'm currently waiting for availability stateside. I'm sitting on an intel HEDT chip right now that will hit 92C on the package on a very light OC (4.64 @ 1.15v) with a -3 AVX offset if you max it out - under a 240mm aio.

TIM sucks, let's stop drinking the koolaid... If you don't think intel doesn't notice that customers and reviewers dislike their decision, and that it may be costing them sales (especially with Zen+ and Zen2 on the horizon) you're crazy.

Zzzzzzzzzzz

It so sucks sooooooo bad, it works on stock and allows overclocking. It allows this cpu to reach iver 5 ghz.....on air. I guess our definition of "sucks" differs. It could be better, sure, but for what???? Oh, thats right, its been explained a dozen times in as many threads already. 100-200mhz more overclock IF YOU ARE LUCKY. Soooooo worth it to chance borking tbe cpu and for sure obliterate the warranty.

I mean you are sitting at 4.6ghz with that same tim...lol

I said this in previous post, Intel doesn't like you to overclock, and you do this on your own risk, and Intel doesn't have to pay for your overclocking adventures. This is something people don't understand. For the stock operations of Intel CPUs, the TIM is fine. Just because you want to set world records, that is on you, you can't blame them.

Interestingly, the i7-8700K also spells trouble for "Skylake-X" Core i7 SKUs such as the i7-7800X and i7-7820X, as it offers multi-threaded performance in proximity to them, while being cheaper overall.
Ryzen caused such a panic that they have Intel stepping on their own toes...gotta love it. Interestingly enough, might jump ship to Intel.

Strangely all i can think after seeing this is Kabylake-X. Those 4core HEDT got to be so awkward after this new Coffee lake line up.

It's silly that replacing the TIM is (essentially for overclockers) necessary with Intel. Intel knows it's a problem and would cost them little yet they continue to do it.

That said, it's very easy and safe with the tools out there to replace it. Don't do the YouTube vice/hammer method. There are devices out there for $20-$30 that make removing and reinstalling the heat spreader a snap. I use the Rockit one but there are all sorts of alternatives out there that work great. Dropped temps significantly for me and has lasted. By the time the good TIM would need replaced I'll be replacing the hw anyway.

You're right! They can 'afford' not to - and they can afford to release undervolted chips well below their frequency headroom because the competition hasn't caught up. Intel doesn't have to pay or care about anything I do - only I do that and I vote with my wallet... So yeah - none of those things changes the fact that TIM is inferior in terms of product performance from the point of view of the consumer; and it was a decision that they made because they could.

And it's fine to criticize them for it - because it does detract from the product - and if it was soldered consumers could get higher stock frequencies on their chips / better sustained boost as well, so it's not just the one-off overclocker that gets an inferior product.

Nor is it great.



Many from this thread would disagree with that. Or rather they would insist there is nothing to criticize about.
From the review:

And I'm disappointed that I use beetle oil between the IHS and the pill, just as I'm disappointed that CPU prices have increased and although we're dealing with a slightly improved architecture, the new processors can not work on the Z270 motherboards.

Higher sustained boost? No... doesn't really work that way...with the stock intel cooler, all intel CPUs will hit their boost clocks. They are made for such behavior. So really, it is just the one-off overclocker that has issues with it. HEDT also doesn't come with a cooler...
Nor is it great.

I didn't say it was great. What I am saying is that it doesn't "suck". And there is clear evidence that it does not suck. People are welcome to criticize it. Just don't be surprised to continue seeing the same type responses from those who disagree with something completely untrue. I mean, writing is on the wall it can be better (to what end though is another question already answered). But it does not SUCK, again, as evidenced by its stock performance and out of spec performance (overclocking). 5.1 Ghz on air SUCKS for a hex-core... my 4.5 Ghz 20t SUCKS... 7700K at 5Ghz SUCKS... Good call on suck (phanbeuy). ;)

I don't agree, non-overclockers have nothing to complain about. Stock operation will be the same with any cooler with any other TIM.
