Here are some pics and video of my 8 x Xilinx VCU1525 rig. Each VCU1525 card has one Xilinx VU9P Virtex Ultrascale+ FPGA. Hash rate for the whole rig combined is:
Keccak (Smartcash, Maxcoin): 136GH/s (17GH/s per card x eight) ($160/day at Apr-30 prices)
Tribus (Denarius, Virtus): 16.8GH/s (2.1GH/s per card x eight) ($304/day at Apr-30 prices)
Phi1612 (Luxcoin, Folm): 5.2GH/s (650MH/s per card x eight) ($456/day at Apr-30 prices)
Skunhash (Various coins): 10.4GH/s (1.3GH/s per card x eight) ($261/day at Apr-30 prices)
Those yield around US$20-$57 per card per day ($160-$456 per day for the rig). Each VCU1525 card costs $4000, or $32K for the whole rig. At $160-$456 per day, ROI is 70-200 days depending on the algorithm. I'm not the only one mining with these cards. Apparently some guy in Germany is getting 64KH/s with Cryptonight-V7 on the same VCU1525's, earning him over $100 per day per card or $800+ per day for a whole rig.
I am very excited that we get to see some evidence today, a Xilinx VCU1525 operating at 20x the throughput of an Nvidia GTX 1080 Ti while consuming less than 161 watts of power.

Aside, AVNET has come alive today for me and asking for payment.
