    So guys, where do you expect Core i7-8700K to land in terms of clock speed? Might give you a surprise later today.

    Edit: I want stock base clocks + Turbo modes.

    Stock or Overclock?

    Im expecting 3.7/4.2/4.4 stock with 80% of chips capable of 4.8ghz.

    And I consider that an aggressive expectation, so if Intel beats that props to them.

    +1 That's roughly mine guess as well, ofc 4.8GHz would be "damn good" for a 6 core IMO and to even reach that the process has been to have gone rather smoothly. If it can surpass that at reasonable voltage & temperature, then that would be something... based on that one ES though, 4.8GHz sounds very doable.

    Before this month I had more like 4.6~4.7GHz max clocks in 80~90% of the cases on air/water expecation, but as closer we get the more faith I've gotten. :p

    When you want to show a screenshot from CPU-Z, it's smart idea is to prevent CPU downclocking before making a screenshot.

    I'm so hardcore overclocker, looking at a CPU running at defaults is giving me weird feeling. Are really people who are doing that? Then I remember, majority of them, I just never see them to show a picture of theirs PC or internals.

    These should be real world clocks, these CPU should be really close to launch this leaked.

    4.8ghz is going to cook your board and cooler - maybe those of you with mATX and ATX rigs, very pricey coolers and at least 3 system fans will be fine - but considering the known 7700k heat spikes, I'll actually be very happy with even just 4.3ghz. It'll still decimate a Ryzen system considering it has a higher frequency, higher IPC and contains the 'free' video card I'd like (as a non gamer)

    Win win.

    First to vote!
    4.1 ghz would be a good stock turbo clock.

    That would make it about 10% lower at single thread and 30% higher at multi thread over a 7700k assuming 3.7/4.1 ghz. Anything over that is a bonus.

    6.0GHz. On all cores. At all times. With a 40w TDP.

    Anything less and Intel has failed. :ROFLMAO:

    Isn't the max for the 7700k 4.5 ghz sc? I can't see even the sc clocks being higher due to the greater complexity. Also, it would be strange for Intel to have the 8800k that much faster than the 7800x.

    This is on the latest node though so will have certain improvements, just comes down to whether Intel decides to create some artificial barriers or not and the difference between official clocks and good sustainable overclocks on the K model (could be important for this product range this time round).

    Cheers

    Besides Intel PR, do we actually know what the "new node" can do?

    Thank you, so sick of people claiming it is some kind of magic. End of that day, it's still 14nm

    I heard 15% 14nm++ was a total of 30% better than regular 14nm. Kaby had a 400mhz better max OC over SKL. 5.2ghz vs 4.8GHz and lower voltage IIRC for that so 8% but also better voltages IIRC.

    The overall average chip on Kaby was much better than 8% though.

    Kaby Lake was already having heat problems I wonder how they will add on two more cores without telling consumers to buy water.
    Maybe we are approaching a time when overclocking an Intel chip comes with a pre-requisite of delidding.

    Damn, 4.4 ghz with 4-cores - even higher than the 7740x. The cpu will probably be a little pricier but the mb will no doubt be cheaper.

    This should be able to do close to 4.8 ghz all core o/c as others have suggested.

    the heat per square mm is the same so no issues.

    Yeah, more total heat generated, but more surface in contact with the heatspreader- so not much harder to cool so long as the capacity is there (and if it isn't, it'll just throttle).

    I actually found a die shot of the 7700k and noticed that the actual cores themselves really consisted of significantly less die area than you'd think - considering shared cache, other logic, GPU etc

    I would hazard a guess, adding 2 more cores could be as little as 20% more surface area.
    I still think they'd want a lower voltage and frequency to ensure we don't hit those random 100c spikes, like we're seeing on the 7700k

    Here is me hoping that Ryzen will keep up the pressure and maybe see an 8C/16T i7-9700k?

    Might have trouble fitting the iGPU on that one - if you want 8 core, x299 for you.
    (You might not like the iGPU, some of us do and it is part of the 1151 platform)

    Zen+ or Zen2 might force that if AMD start to introduce 10+cores for mainstream lol. I. Can't. Wait.

    Don't particuarly care too much about the lack of iGPU, chances are I'll probably have a few spare GPUs lying around the house if the current GPU dies.

    My problem with X platforms in general is the PCI-E lanes. 16 lane CPU on X platform just really compounds the cost of the system for no real good reason, and I probably will never settle for a 28 lane CPU (whoever thought 28 lanes was a good idea should be tarred and feathered, preferably a few times), so yeah...

    So due to all the leaks happening now, it's starting to look like a launch in roughly 1 month after all? To me that would be a good indication that there will be backwards compatibility added on Z270 (and maybe Z170).

    It's a self fullfilling prophecy though, all the leaks said august, so the fake leakers will ramp up, just before august, won't they?

    We really won't know until some more concrete evidence comes up.

    For the higher core count parts, Intel can strip the iGPU down to next to nothing- it doesn't have to play games, just spit out a display for the spec. I even use them on my gaming system, and that's as much as I need. Free outputs for extra monitors either way.

    I agree, as long as it can do 3 monitors 4k 60Hz, 2d Windows, I'm happy

    Coffee Lake uses 14nm++. SKL-X and Kabylake use 14nm+.

    Also Coffee Lake is a simpler core than the one used in 7800X (no 512bit units, 1/4th of L2) and that affects f_max as well.

    That is Intel PR though. Im not saying there wont be improvements, but I need to see it before I outright believe it.

    With 4.6-4.7 GHz Turbo for 1-2 core operations and 50% extra L3 cache I believe i7-8700K will be the new king for CPU-intensive games and other apps that require stellar performance-per-core.

    The entire lineup is aggressively clocked and competitive, people will be positively surprised. :coffee:

    Except for the AMD fanbois that will already insist 6 core and clock frequencies & IPC is a thing of the past and despite real world tests showing a different result. Emulators that I'm interesting in, is particularly funny scenario where you can get linear performance boost with clock frequency scaling.

    Extreme AMD Fanboys are annoying, yes. But Ryzen is a great option for a lot of builders. A 6 core / 12 thread processor for $219 with a cooler that will allow you to take it to 4GHZ is pretty absurd.

    For absolute peak performance, Intel is clearly still the better option though. Which is why im holding off on CoffeeLake. I want 6 cores at 5GHZ.

    CFL supposed to have any new instructions or DRM enhancements over KBL as it relates to UHD/4K playback n compatibility?

    Any OTHER reasons to go CFL besides core/thread count? Same lanes, same MoBos etc.
