    Nope, not sure at all That particularly bit is just me making an assumption based on how they handled AVX2 in Haswell. They might well have stuck with narrower datapaths, similar to what they did in Sandy Bridge.

    Have a look at RWT forum, there is a thread somewhere recently talking about it. Quite interesting read. Follow the trail of Linus posts

    Threadripper is up to 16 cores and 40 or 36 lanes available for slots (4 lanes to chipset and 4 or 8 lanes for M.2 NVMe).

    However, is there anything stopping AMD from marketing 4-chip or 3-chip Naples to enthusiasts and offer various core counts? Imagine a 24-core monster with four 6-core CCX units at ~160 W TDP.
    Eight memory channels and 64 PCIe lanes...

    Sorry for the brain fart. 64 lanes per one Threadripper. Somehow I forgot the lane arrangement for TR and imagined a scaled-down Epyc, or something like that.

    And from the pictures, it's clear that Epyc uses the same socket as Threadripper. I'm wondering how memory lines are arranged on Threadripper vs. Epyc. Imagine if Threadripper had four channels and two complete sets of lines per channel. So if you put a TR in the socket, it only serves four channels, but allows two DIMMs per channel, but if you put Epyc in there, it lets you have eight-channel memory instead.

I won't presume anything about its IPC until I see benchmarks!
    Yeah, I was reading about the cache hierarchy yesterday, it definitely sounds like it should impact IPC in a positive way.

    My sources told me Intel could release a v2 edition of Socket 2066.

    Another Intel socket, this is fine.

    Talking about 2066v2?
    That's ok, I never wanted to buy 18 core Intel CPU, I only needed 4 cores for my gaming !!!11!

    Anyone else thinking 14, 16 and 18 cores are a rush job.
    Good luck to those who buy it (if they ever can).

    The whole thing is a rush job only put out into productions when their spies got info about Threadripper. Gigabyte mentioned that they did not have enough time to validate thunderbolt connections
