Core i7-8700K Reviewed by Lab501
Ahead of the 5th October reviews NDA, Lab501 posted their review of the Core i7-8700K six-core processor using samples not provided by Intel, paired with an Aorus Z370 Ultra Gaming motherboard. The tests reveal that the i7-8700K trades blows with the Ryzen 7 1800X in multi-threaded tests, despite two fewer cores, and has a clear leadership in single-threaded tests. It also reveals that the i7-8700K may not be as pricier than the i7-7700K as previously thought. 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.
The Core i7-8700K is able to sustain its Turbo Boost frequencies of 4.20 GHz better than Intel's other Core X HEDT chips, which translates into higher gaming performance. The tests reveal that today's games still don't need six cores, and on the merit of high sustained clock speeds alone, the i7-8700K is shaping up to be among the fastest processors you can choose for gaming PC builds. Lab501 also got the i7-8700K to overclock to 5.1 GHz with relative ease. The chip runs feisty hot at overclocked speeds, but rewards with HEDT-like performance. Find other interesting findings of Lab501 in the source link below.
More results follow.

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.
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.
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
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.
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.
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.
:roll: google translate...
7700K Delidded - ~20C drop with a 200Mhz headroom increase...
7820x Delidded - ~20C drop OC increase to 4.9-5.0Ghz range no throttling - stock paste - throttling at 4.7Ghz+ after sustained max load
7900X Delidded - VRMs explode and your house lights on fire. But the chip is cool...
8700K 14nm ++ with a delid will be sitting around 5.3 GHz at around 1.45v (my prediction)
And when I say "Higher sustained boost" I mean "they could release a higher clocked chip, with higher boost" (a-la AMD and the 1800x, where the chip is basically maxed out).So you think Intel has maxed out the headroom left in their chips, and can't offer a higher clocked chip to the mass market?
