While individually the Xilinx UltraScale VU440 devices deliver increase performance, Xilinx quotes the (-1) speed grade having the same logic performance as the Xilinx Virtex-7 2000T (-2) speed grade, this unfortunately has very little effect on multi-FPGA prototype performance. The reason is that the performance bottleneck is not the speed of the logic in the FPGA device itself, it’s the overall multi-FPGA interconnectivity, we like to call this the pin-multiplexing bottleneck. Take the simple example below where an SoC is partitioned across multiple FPGA’s.
