    PCI Express 4.0 to offer double bandwidth, and 4x power delivery

    The final specification should be complete by the end of the year.

    Re: PCI Express 4.0 to offer double bandwidth, and 4x power delivery

    PCIe 3.0 is certified for 75W delivery. A 300W+ delivery at the socket could remove the need for extra power connectors for even the most powerful graphics cards.
    I wonder if that means we'll just see the pci-e connectors moved to the motherboard rather than the card?
    If this is the case then, given that motherboards already have the 24 pin and 4/8pin CPU power connectors, it seems to me that it could be time for a revised PSU spec combining all of these into a single connector.

    300W from the PCIe slot brings new meaning to the phrase "bus-powered graphics card"...

    I'm all for this, so long as a new single connector isn't any fatter than the 24 pin one! That thing's hard enough to route in a case as it is.

    Re: PCI Express 4.0 to offer double bandwidth, and 4x power delivery

    It does sound like there will need to be a new PSU specification to delivery enough power to the motherboard.

    Of course, it's nice that manufacturers are readying products, but we have to wait for Intel and the likes to implement it in their chipsets too.

    PCI-E power connectors on the motherboard??

    The power still needs to come from somewhere and you can't use the existing 20 pin ATX connector for this. Don't see where the advantage for the user is. Probably just gonna make the motherboards more expensive.

    Fixed that for you

    Cheap motherboards will always be cheap.

    Edit: I suppose USB-C power delivery is already increasing the power requirements of motherboards significantly, so if the connectors are going to change at all we may as well add another KW or two for graphics cards.

    By the looks of it the PCI-E connectors simply move to the motherboard.

    ***WILD SPECULATION***

    could this be the reason for AMD Zen delay?
    they're just waiting for final spec before launching. get a jump on Intel. article does say AMD were using it on the Naples demo.

    could also be why the RX480 drew more power than expected from the PCI-E port its just using the newer tech stuff.

    it makes sense if you think about it.

    Re: PCI Express 4.0 to offer double bandwidth, and 4x power delivery

    I suppose it'll be neater on the motherboard, PCIe power cables are the messy component being dragged out to the front of the case like they all do currently.

    Re: PCI Express 4.0 to offer double bandwidth, and 4x power delivery

    Is there any situation where the bandwidth may be a bottleneck at the moment or is this just future proofing?

    With flash enterprise storage, it could do. PCIe 3 seems pretty much overkill for graphics cards.
