Key differences
The XC7K160T has about 20% more logic capacity (162K vs 135K LUT4 equivalents).
They use different logic architectures: the Certus-N2 CT20 is built from LUT4 and the XC7K160T from LUT6, so the raw LUT counts (135K vs 101K) are not directly comparable.
For arithmetic, the XC7K160T has 600 DSP slices against 520 18×18 multipliers on the Certus-N2 CT20.
Both have transceivers: 8 at up to 16 Gb/s on the Certus-N2 CT20 and 8 at up to 12.5 Gb/s on the XC7K160T.
The Certus-N2 CT20 is designed with Lattice Radiant and the XC7K160T with AMD Vivado.
