Key differences
The LFD2NX-35 has about 14% more logic capacity (29.2K vs 25.6K LUT4 equivalents).
They use different logic architectures: the LFD2NX-35 is built from LUT4 and the XCSU35P from LUT6, so the raw LUT counts (29.2K vs 16K) are not directly comparable.
The LFD2NX-35 has more on-chip memory (2.4 Mb vs 1.7 Mb).
Only the LFD2NX-35 has multi-gigabit transceivers (1 5 Gb/s).
The LFD2NX-35 is designed with Lattice Radiant and the XCSU35P with AMD Vivado.
