Key differences
The LFMXO5-15D has about 46% more logic capacity (11.7K vs 8K LUT4 equivalents).
They use different logic architectures: the LFMXO5-15D is built from LUT4 and the XCSU10P from LUT6, so the raw LUT counts (11.7K vs 5K) are not directly comparable.
For arithmetic, the XCSU10P has 24 DSP slices against 16 18×18 multipliers on the LFMXO5-15D.
The XCSU10P has more on-chip memory (1.7 Mb vs 0.8 Mb).
Configuration memory: internal flash on the LFMXO5-15D, sram on the XCSU10P.
The LFMXO5-15D is designed with Lattice Radiant and the XCSU10P with AMD Vivado.
