Key differences
The SX 850 has about 19% more logic capacity (570K vs 478K LUT4 equivalents).
They use different logic architectures: the SX 850 is built from ALMs and the XCZU11EG from LUT6, so the raw LUT counts (285K vs 299K) are not directly comparable.
For arithmetic, the XCZU11EG has 2,928 DSP slices against 2,016 variable-precision DSP blocks on the SX 850.
The SX 850 has more on-chip memory (68 Mb vs 43.6 Mb).
Both have transceivers: 48 at up to 28.3 Gb/s on the SX 850 and 48 at up to 32.75 Gb/s on the XCZU11EG.
The SX 850 is designed with Altera Quartus Prime and the XCZU11EG with AMD Vivado.
