I think the parent comment to yours (or at least the edited version) is right, they are almost surely XCVU9Ps based on the logic element and DSP counts. The ram numbers listed in the product table are embedded memories (BlockRAMs in Xilinx-speak), DDR4 wouldn't be a spec-feature of the FPGA as it's external to the part on the PCB. Avnet web pricing is $27k for the -1 speed grade, extended (not industrial) with 12-week lead. Safe to say Amazon is getting a better deal on both counts. I suspect the add-in card itself is either this or something similar to it, based on specs etc. http://www.bittware.com/xilinx/product/xupp3r/ http://www.bittware.com/xilinx/product/xupp3r/. I didn't see pricing info readily available for that, but a similar card with less on-board DDR4 runs about $7k straight from Xilinx: https://www.xilinx.com/products/boards-and-kits/ek-u1-vcu118-es1-g.html https://www.xilinx.com/products/boards-and-kits/ek-u1-vcu118... Edit: Oh yeah, I forgot to add: I thought it was funny that Amazon's page referred to "logic elements" given that this was traditionally an Altera term - Xilinx preferred/prefers "logic cells".
