Key differences
The LFMXO5-25 has about 19% more logic capacity (22.5K vs 18.9K LUT4 equivalents).
They use different logic architectures: the 5CEA2 is built from ALMs and the LFMXO5-25 from LUT4, so the raw LUT counts (9.4K vs 22.5K) are not directly comparable.
For arithmetic, the 5CEA2 has 25 variable-precision DSP blocks against 20 18×18 multipliers on the LFMXO5-25.
Configuration memory: sram on the 5CEA2, internal flash on the LFMXO5-25.
The 5CEA2 is designed with Altera Quartus Prime and the LFMXO5-25 with Lattice Radiant.
