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.
