There is no Pi with 10G ethernet. New Pi4 has only Gigabit ethernet, Pi 3B+ has Gigabit Ethernet over USB 2.0 (maximum throughput 300 Mbps).
The idea is interesting, did some calculation.
For v1 camera capturing 640xH frames can be done at framerate "42755/H+13".
Lets forget about the 13.
raspiraw transfers raw10 Bayer data, that is 640xHx1.25 bytes, with maximal framerate that gives 42755x640x1.25=34204000 bytes/s=261Mbit/s(!).
So you definitely need Gigabit ethernet of the Pi4, not sure whether Pi4 can actually stream out 261Mbit without losing stuff though ...
No answer on the networking forum yet.
I cannot try because I don't have a Pi4 yet.
It seems possible.
An easy test would be to test whether this command will work on Pi4:
and on someIp server service listeing on somePort just storing the data received. Because yuv has 12bits/pixel which is a bit more than the 10bit/pixel of raw Bayer, the command produces a 316Mbps stream of data for v1 camera (732Mbps for v2 camera when recording with "-fps 180"). For testing the service on someIp can be as easy as:
