    I want the CoreXCarbonFiber, with the carbon nanotube IHS.

    In the meantime the IHS should the scrawled with a pencil to help with the high temperatures.

    Higher-end motherboards ought to be able to. Prime95 and Linpack get my very heavily overclocked 6700K up to ~170-180 watts, and my motherboard (Z170 Deluxe) has no apparent problems supplying that.

    VRM heatsinks definitely get toasty, though.

    Your 6700K is starting at 91W rating though. If it started at 135W rating, you'd be blowing up, imo.

    As was said before, I think it was most likely planned long ago and intended as an entry level HEDT chip. It would also have given HEDT a faster single thread/gaming option.

    Circumstances have indeed made it look odd today.

    The 7740k looks on the surface to be almost identical to the 7700k. But, there are important differences.

    Likely differences:
    1) Faster base clock rate (4.3 GHz vs 4.2 GHz).
    2) Systems built around it will be able to handle more power and more heat. Thus it can stay at turbo speed for much longer.
    3) No GPU, so all that power can be dedicated to the CPU.
    4) So far the leaks show that it is supported with faster memory (DDR4-2666 for the 7740k vs DDR-2400 for the 7700k). Since the 7700k is memory starved, this could help quite a bit.

    Possible but unconfirmed differences:
    5) Intel could choose to solder the lid on it (I haven't seen if they are going this route or not).
    6) Intel could choose to price it right with Ryzen now in the picture. This avoids the issue of investors not liking a chip price cut without a replacement chip. And/or this could be the replacement chip allowing the 7700k to get a nice price cut.

    If Intel goes all the way and does all 6 of those, then it will address virtually everything that enthusiasts here complained about the 7700k when it was launched. That would make it a great HEDT entry level chip. If not, at least it isn't worse than the 7700k. I'll take every small bump between ticks/tocks that I can get.

    7700K already seems to stay at 4.4 with 4 cores active if you have good cooling.
    So I doubt the 7740K is going to show much turbo improvement.

    If the 7740k is soldered it should debunk all these theories that Intel isn't using solder on mainstream processors due to die size.

    The 7740K is a DOA chip, it will take it's rightful place right next to the 5775C.

    Don't forget the HEDT i5, the 7640K...it makes even less sense than the 7740K.

    Unless there is something big we are missing, I can't see any sense in releasing these chips given the situation today.

    CoreXLead?

    One tier below Bronze?

    The 7740k has a higher boost clock (4.5 GHz vs 4.4 GHz). But, you are correct that it isn't much different. The extra power might let Intel use borderline chips and thus have a higher yield and lower cost to them.

    The only thing I can see that might redeem the KL-X chips would be if they had some impressive clock speeds. Like maybe a 4.5 base and 5.0 boost. Impressive clocks might make for some nice gaming numbers...but that is just reaching, as there's been no sign of any impressive clocks. More like unimpressive clocks.

    Pewter, you can shine Pewter up to look really good.

    Kaby Lake-X will be a hard sell after Coffee Lake-S arrives. 4C/6C options at an improved 14++ process, probably similar prices as well. I would prefer if they cancelled this product in favor of an earlier than expected Coffee Lake-X launch. Now that's more exciting, 6C @ 14nm++ without LGA 1151's TDP restriction.

    which translates to needing new boards...

    :T

    what ever happened with boards lasting though the entire tick tock cycle?
    Well now we got 3 stages, but wouldn't it make sense to have it last though the entire cycle and not require an upgrade?

    Z170 -> Z270 was bad enough, but now were gonna get something like a Z275 to support 6C?

    Nah, most Z270 boards are expected to support CFL with a BIOS update. Nobody's really sure about Z170's, it'll probably depend on the vendor.
    Part of what is going on is that these vendors still need to sell motherboards - so, they don't talk up support for new CPUs on older boards.

    What tick tock cycle?
    Intel's doing tick, tick, tick .... BOOM!

    Why do you think so? By the looks of it Z270 will support Coffeelake, the CFL 6C entry on Sisoft was made on a Kabylake platform.

    The 5120 seems right in line with their existing 14C products (core count, speed, and price). But that 5122 is way, way faster than their existing 12C parts, yet it is at about the same price. What am I missing? Sure, there is a little less cache, but that is just far faster. Is it limited in some other way?

    Which coffee lake is launching in August 2017?
