    Not new really, they're just cut down 2080 and 2070. Same pcb etc.

    dont think current cards would saturate 3.0 nevermind 4 tbh.

    Good luck with that, but PCIe 4.0 doesn't magically make a GPU faster. Current Gen cards barely utilize PCIe 3.0 8x, what would they do with 4.0 x16? Have it idle most of the time is what.

    The main (and only) use for pcie 4.0 is be the SSD pcie NVME connector at this time.

    Maybe one year more to see pcie4.0 graphics cards.

    believe the new 5700 cards support pcie 4, but it wont utilise the whole bandwidth.

    Bandwidth/lane is only interesting for devices with low number of lanes (1-4x) available (due to form factor or sharing) and for some sever gear (controller cards with multiple optical lanes or top of the line speeds per lane).

    Well considering 5 shall be out soon :) besides that, just look at the problems board manufacturers are having with speeds being lower than devices being on PCIe 3.
    I'd check out benchmarks before buying anything, esp with new tech..

    honestly SSD for PCIE4 its crap for this time
    slower than all 960/970 from samsung, slower thna WD 750 BE
    just R/W its better
    overral performance its middle
    need time for full utiliziatin PCIE4, and second not all NVME PCIe3 its better than SATA3

    Maximum sequential read/write are fine and all, but in the real world the low queue random access tasks is what matters the most, and the PCIe4 SSDs that have shown up so far may have faster sequential speed due to PCIe4, but if they lack in real-world tasks, its not exactly an upgrade.
    If one wants true high-end, we'll need PCIe4 SSDs with decent consumer-focused controllers like the Samsung SSDs, or even Corsairs own earlier SSD (ie. not based on that one Phison controller that every current PCIe4 SSD uses)

    That Phison controller just isn't true high-end. All it has going for it is PCIe4, but not much else.

    This is true, but in reality what matters most is parallel operations on a disk, you won't even notice the throughput difference in sequential under any gaming circumstances as the Guru3D gaming load tests demonstrated.
