In a stunning bit of Twitter, a tweet from one of the leading motherboard manufacturers has stated that Coffee Lake, Intel’s 8th Generation Core processors, will not be supported on the current generation of 200-series motherboards.

Information like this is usually kept under wraps until an Intel reveal, but it seems to have been mindlessly posted to Twitter on July 31st, an account that last tweeted on April 11th before this tweet occurred. This tweet has since been deleted.

At this point, due to the similar microarchitecture to Kaby Lake being used in Coffee Lake, most of the technology press were under the impression that the Coffee Lake processors would be compatible with LGA1151 socket motherboards, namely the 100-series and 200-series. With the above tweet essentially confirming that Coffee Lake will not be supported, it means that either the new CPUs will not be LGA1151, or that the motherboards will lock-out the processors by firmware, or the CPUs and sockets will use a different notching system to ensure the wrong processor cannot be put in the wrong board. It does mean however that 200-series users hoping to upgrade to a Coffee Lake processor (which early reports are suggesting might be up to six cores, but this has not been announced) will not be able to.

There are many potential reasons for the change if the socket is still LGA1151. The obvious one would be product segmentation on Intel’s part, which would stick in the craw for a number of the user base. The second one that it might actually be a physical requirement for the processor – if previously unused pins are required for power and/or control for different elements of the DVFS in the chip. This would depend on new features on the chip, which could extend to different power management, different graphics, or different IP blocks that require separate pin-out connections. Intel might also be using a different power system for voltage regulators, which might not be compatible with current 200-series motherboards.

At this point, nothing has been made official. The fact that this was stated on Twitter so far from any launch date that we know of is an interesting development.

    Ryzen 5 1600 for $200 6c/12t. Coffee Lake at half the price :D

    If they don't change the pin count, even if it's just a placement pin, it's going to cause a lot of confusion.
    Actually their whole release schedule and products have been confusing.

    Very dissapointing. I've got an i7-6700 on a z170, and I probably would buy a six core i7 if it would work on my board. Now I'll definitely wait as a new mobo adds about $150 to the cost. If Zen 2 is good enough I'll jump over there maybe

    exactly my thoughts

    Do people actually upgrade their processors a single generation? Does requiring a new motherboard actually effect anyone at all. I would assume anyone doing such an upgrade for such little gain would probably have the money to fork out for a new motherboard too.

    Especially relevant when, for gaming, it's normally the GPU that matters more, though in these newer times of emergent multi-core support for gaming, live streaming, and being able to cope with background tasks on a "typical" system (something tech review sites never check), AMD's higher core count CPUs make a lot more sense atm, hence the results GN had when comparing Ryzen 1700 vs. 7700K for game streaming. Intel is not moving in the same direction as the gaming public wants to go, especially the enthusiasts. Now they're playing catchup, and making a mess of it.

    Intel will always laugh at you.

    If you want a quad core for gaming, Ryzen 5 1500X is your chip. At 1440p/4k a 1500X at 4Ghz vs 7700K at 5Ghz is 95% as fast with a 1080ti.

    Meanwhile with the current AM4 you can upgrade all the way to Zen3 7nm+ in 2020 :D

    doesn't every gen come with a new chipset?
  • Mikuni - Friday, August 4, 2017 - link

    this isn't a new gen
