    AMD Zen based Opteron chips detailed in CERN slides

    A computer engineer at CERN used the slides when discussing data centre capabilities.

    I feel this story needs a "Sharp-eyed Hexus regular CAT-THE-FIFTH spotted yesterday ...." somewhere in it:

    The slide doesn't mean that Liviu Valsan has insider knowledge, it's just a matter of putting various leaks and rumours together.

    ANYWAY: best of luck coz intel is already producing 14nm chips and has HT. It wont be a game changer am sure what will hold AMD's name for the next 2 years is producing PS4 and Xbox1 chips. Losses will still be there untill I see more laptops and desktops with AMD inside maybe Apple will shift all together!

    Pretty sure the tides will turn if Intel keeps releasing paper-thin chips that bug out under full load ;D

    Re: AMD Zen based Opteron chips detailed in CERN slides

    I would switch to AMD if their Zen chipsets
    would support modern RAID modes with at
    minimum of four U.2 ports e.g. there is
    room for three more U.2 ports if we eliminate
    DOA SATA-Express ports:

    I dont think AMD can afford to offer anything other than unlocked chips

    If they continue the trend set with the original K8 processors and also support ECC on "consumer" models, then I just might get tempted back to AMD.

    Re: AMD Zen based Opteron chips detailed in CERN slides

    I dont want to run for unlocked I just want a processor that runs at 3.0ghz yet comparable in performance to the old timer Bulldozer that ran @ 4ghz but offered very little. This should be a smart game no wonder most of the unlocked AMD 4 core's were taken down by mere low hertz intel i3's in benchmarks.

    Re: AMD Zen based Opteron chips detailed in CERN slides

    I'd imagine the eight memory channels are made up of two dies each with a 4-channel IMC on a multi-chip-module much like the Socket G34 Opterons were two 2-channel chips in a single socket.

    Using HBM to boost bandwidth sounds interesting though, even though I can't see how it's much different than Intel using eDRAM on Broadwell and Skylake Xeons to boost bandwidth other than potentially being cheaper and thus more widely adopted.

    However, these Zen-based Opterons will be up against Skylake Xeons on the Purley platform with 6-channel IMC supporting 3D X-point, and so it'll be interesting to compare the two approaches.

    You either want a modern filesystem like ZFS or BTRFS, or you want a hardware raid controller with battery backed cache for old school RAID. Anything else is a bit of a toy anyway.

    In what benchmarks? and at what extra cost?

    Re: AMD Zen based Opteron chips detailed in CERN slides

    I knew this guy from when I worked at CERN. He works in CERN's openlab project and they do have contacts with the major vendors, but as skyobee said it's just as likely the info is inferred from the various leaks and rumours. Nice to know he's still working there
