Key differences
The XCSU60P has about 9% more logic capacity (48K vs 44.2K LUT4 equivalents).
They use different logic architectures: the LFMXO5-55T is built from LUT4 and the XCSU60P from LUT6, so the raw LUT counts (44.2K vs 30K) are not directly comparable.
For arithmetic, the LFMXO5-55T has 146 18×18 multipliers against 144 DSP slices on the XCSU60P.
The LFMXO5-55T has more on-chip memory (5.4 Mb vs 3.4 Mb).
Both have transceivers: 2 at up to 0 Gb/s on the LFMXO5-55T and 4 at up to 16.3 Gb/s on the XCSU60P.
Configuration memory: internal flash on the LFMXO5-55T, sram on the XCSU60P.
The LFMXO5-55T is designed with Lattice Radiant and the XCSU60P with AMD Vivado.
