Key differences
The XCVU3P has about 11% more logic capacity (630K vs 570K LUT4 equivalents).
They use different logic architectures: the GX 850 is built from ALMs and the XCVU3P from LUT6, so the raw LUT counts (285K vs 394K) are not directly comparable.
For arithmetic, the XCVU3P has 2,280 DSP slices against 2,016 variable-precision DSP blocks on the GX 850.
The XCVU3P has more on-chip memory (115.3 Mb vs 68 Mb).
Both have transceivers: 48 at up to 28.3 Gb/s on the GX 850 and 40 at up to 32.75 Gb/s on the XCVU3P.
The GX 850 is designed with Altera Quartus Prime and the XCVU3P with AMD Vivado.
