Key differences
The 5CGXC5 has about 21% more logic capacity (58.2K vs 48K LUT4 equivalents).
They use different logic architectures: the 5CGXC5 is built from ALMs and the XCSU65P from LUT6, so the raw LUT counts (29.1K vs 30K) are not directly comparable.
For arithmetic, the 5CGXC5 has 150 variable-precision DSP blocks against 144 DSP slices on the XCSU65P.
The 5CGXC5 has more on-chip memory (4.4 Mb vs 3.8 Mb).
Both have transceivers: 6 at up to 3.125 Gb/s on the 5CGXC5 and 4 at up to 16.3 Gb/s on the XCSU65P.
The 5CGXC5 is designed with Altera Quartus Prime and the XCSU65P with AMD Vivado.
