With x16r and x17 requiring 2 cards would that be 300mh/s for both cards? Or 300 each equalling 600mh for two cards daisy chained together?

Clarifying the projected hash rates
X17: 2 cards daisy chained get 600MH/s total
X16R: 2 cards daisy chained get 600MH/s total
Xevan: 4 Bittware cards daisy chained get 600MH/s total

so I'm guessing that the VCU1525 can be daisy chained to two cards max hence being able to hash on X17 and X16R?

VCU1525 has 2 x QSFP28 connectors, so you link 2 boards with 2 x 100 gigabit ethernet cables, and two boards is the max that can be daisy chained. With the Bittware XUPP3R board, since it has 4 x QSFP28 connectors, there is no limit to the daisy chain length. These specialized ethernet cables have nothing to do with internet, they are solely so data can flow from one FPGA board to the next board. The cables are around $40 each.

Personally I think GPU mining will still be around for a while. I believe the market is going to rise so dramatically this fall that all existing GPU rigs will be making a lot of money, even with rises in difficulty.

If youre not constrained to the 1525 (though most non-FPGA devs will be), use something like this and you have 600Gbps between boards or 300Gbps chain.
