    Is there some way to connect Expresscard into USB 3.0

    by some type of adapter . since these days most of laptop manufacturers have stopped including Expresscard slots in their laptops ,

    so How can a Vidock , DIY eGPU can be connected to them ???

    -------------------------

    Now As per wikipedia -

    USB 3.0 offers 5 Gb/s bandwidth , Expresscard 2.0 offers PCIe 2.0 with 5 Gbit/s
    and PCI express bandwidth for

    Per lane (each direction): ( i.e. for x1 PCI express)

    v1.x: 250MB/s (2.5GT/s) = 2000 Mb/s (2 Gb/s)
    v2.x: 500MB/s (5GT/s) = 4 Gb/s
    v3.0: 985MB/s (8GT/s) = 7.88 Gb/s
    v4.0: 1969MB/s (16GT/s) = 15.75 Gb/s

    i mean it's like accommodating 4-5 Gb/s of x1 PCI express thing into USB 3.0 .

    I 've also seen Sony made a USB 3.0 Docking station for it's Z-series

    http://www.pcgamer.com/2011/09/20/hands-on-with-sonys-external-graphics-card-its-superb/

    so it should be possible some way connecting eGPUs via USB 3.0.

    -----------------------

    Also , i know aout Thunderbolt , but that rather an emerging Technology interface , and not that many
    laptops are present in market with thunderbolt , hardly 6 or 8 . Plus for it's new tech they are expensive.

    People are using the motherboard's WiFi slot to connect eGPUs since that's a PCI-E interface.

    i didn't find anything over google regarding connecting eGPU via WiFi's

    what's the bandwidth of WiFi's anyway ? Can they even do 5 Gb/s transfer

    they use the mpcie slot that the wifi uses, they don't do the connection through the wifi itself.

    this has been asked and USB3 isn't a solution for egpus, it can't provide a stable enough connection, it uses cpu resources more and there isn't a connector that we are aware of

    Originally, USB was made for peripherals that required low bandwidth and didn't require low latency and more direct access like what PCI-E provides. Bandwidth is better, but that's it, you'd still run into other issues. It is simply not an option for eGPU. If you want an eGPU, get a business laptop with expresscard.
