    If they can really get a 40% improvement over Excavator, and I mean 40% on average, not on a few select benchmarks, then AMD has a serious chance of being a compelling option once again.

    I'm hoping to see more improvements on Floating Point, which was comically bad in Bulldozer.

    A big part of the problem is that we don't know how well Zen will clock or the power consumption. Still, this should be a major leap in performance overall. We'll have to wait for the launch day benchmarks to see the true story.

    Another big concern is the platform. CPU performance is only part of the story. We need a good platform that can rival the Z170 and Intel HEDT platforms for this to be compelling on the desktop. For mobile, there will have to be good dual channel Zen APUs (Carrizo, as Anandtech noted was heavily gimped by poor quality OEM designs obsessed with cost cutting).

    Yeah I don't think OEMs and others are that worried about supporting AMD. AMD have withered away so much, making AMD CPU capable gear must have become a very minor part of say ASUS/Gigabyte/MSI etc. revenue stream. Making AMD based graphics cards is okay but motherboards? Not so much. Reply

    I wouldn't speak so soon. Just this year MSI and Gigabyte (at least) have introduced new AM3+ boards with USB 3.1 and PCIe 3.0. Why, I'm not sure, but if they're doing that for something as old and deprecated as the FX chips, it would defy logic for Zen to come out and for them to only release a few token efforts.

    I will say, if the CPUs are good but you're right about OEMs not being concerned with support, then the first OEM to say "hey, why don't we make some actually good AM4 boards?" is going to make an absolute killing.

    Are you sure about the PCI-E v3 on AM3+ motherboards? I can find recent releases that have USB3.1 and M.2, but none that support PCI-Ev3. Can you link me or provide a model number? I didn't think 3rd generation PCI-E was possible on the Bulldozer line. Reply

    A little misleading . The Graphics pci-e controller is built in to an FX processor so adding a pci-e 3 standard slot to a motherboard will make no difference to actual bandwidth.
    Not an issue though since x16 pci-e 2 has the same bandwidth as x8 pci-e 3 and intel boards with SLI/crossfire ability running at x8/x8 do not choke any current graphics card

    What about PCI-E SSDs? Can I get full bandwidth on those? I agree about the graphics cards but that's not so important to me. If I can get full PCI-Ev3 x4 performance for an SSD then I'll pribably buy this as a hold-over until Zen. Thanks fir the link! Reply

    Pci-e 3.0 x4 should be the same as 2.0 x 8. So long as you have a vacant x8 it should theoretically work the same. Reply

    I think they use a PLX chip and turn the 32 2.0 lanes from the FX chip into 16 3.0 lanes. Reply
