Key differences
The XCSU25P has about 13% more logic capacity (16K vs 14.2K LUT4 equivalents).
They use different logic architectures: the LFD2NX-17 is built from LUT4 and the XCSU25P from LUT6, so the raw LUT counts (14.2K vs 10K) are not directly comparable.
For arithmetic, the XCSU25P has 36 DSP slices against 24 18×18 multipliers on the LFD2NX-17.
The LFD2NX-17 has more on-chip memory (2.9 Mb vs 1.7 Mb).
The LFD2NX-17 is designed with Lattice Radiant and the XCSU25P with AMD Vivado.
