usb to gpu option

[cavaliersrus]

question for altcoin miners i have seen the use of thunderbolt 2 and 3 to do a external gpu like on gpunerd.com

but would there be an option like this for usb 2.0 or so where you could use something like a raspberri pi to control the gpu for mining like you do with a usb miner like the gekko science compac sticks and futurebit moonlander projects on here ?

why that  when you have risers.

just use a usb 3 to the mobo 

use a pcie cable to the riser
use a pcie cable  to the gpu

pretend the cable they show is a full pcie cable

A true PCIE-USB would be ideal for universal compatibility.

Kinda like the pcmcia pci adaptors were a niche thing.

I wonder how many display adaptors you could 'data pipe' through a usb3.0 plug...

Imagine a USB miner with simple driver the. People use their favorite os/miners.

No hunting for 7gpu capable boards.  Just a box with power and a USB hookup.

Some theoritical bandwidth figures:

PCIe 1.0 x1 (USB riser): 250 MB/s
USB 2.0: 60 MB/s
USB 3.0: 640 MB/s
Thunderbolt 2: 5120 MB/s

250 MB/s is more than enough. I think for most algos even a fraction of that would work without any slowdown.

I'd imagine daisychaining and controlling the cards with software would where the issues come in.

phil i was thinking a usb option to possibly try with a raspberry pi cause they do not have pcie

This was the ultimate thought here as well.   But the universal nature of it would be sorta sweet =)  If you wanted more bandwidth, just do multiple connections and split traffic.

yeah I was thinking a pc to a usb hub and thats how the net causes confusion.

It would be nice to use a usb 3 to pi option.

i would agree phil i have a pi zero and also a pi 2 b+ 512MB i would like to do something like this on cause i could then run a light version of linux on the pi with my usb sticks and then graphics card

As a kid I knew the guy whom did the first pcmcia to isa/pci adapters....  A crazy mess of wires...

I would have to study the PCIE port hardware from the 1-3 splitter and find a way to interface with that via some sort of USB/TTL I would think....   Seems complicated since I don't know the hardware aspect of both well enough.

Might be an idea for a open source community side project of sorts... Lol.  I'd be willing to do some research and put effort in where I can.
