Key differences
Both devices offer similar logic capacity: 54.2K and 52.2K LUT4 equivalents.
They use different logic architectures: the LFD2NX-65 is built from LUT4 and the XC7S50 from LUT6, so the raw LUT counts (54.2K vs 32.6K) are not directly comparable.
For arithmetic, the LFD2NX-65 has 128 18×18 multipliers against 120 DSP slices on the XC7S50.
The LFD2NX-65 has more on-chip memory (3.2 Mb vs 2.6 Mb).
Only the LFD2NX-65 has multi-gigabit transceivers (1 5 Gb/s).
The LFD2NX-65 is designed with Lattice Radiant and the XC7S50 with AMD Vivado.
