Key differences
The LFE5UM5G-85 has about 44% more logic capacity (84K vs 58.2K LUT4 equivalents).
They use different logic architectures: the 5CGXC5 is built from ALMs and the LFE5UM5G-85 from LUT4, so the raw LUT counts (29.1K vs 84K) are not directly comparable.
For arithmetic, the LFE5UM5G-85 has 156 18×18 multipliers against 150 variable-precision DSP blocks on the 5CGXC5.
The 5CGXC5 has more on-chip memory (4.4 Mb vs 3.7 Mb).
Both have transceivers: 6 at up to 3.125 Gb/s on the 5CGXC5 and 4 at up to 5 Gb/s on the LFE5UM5G-85.
The 5CGXC5 is designed with Altera Quartus Prime and the LFE5UM5G-85 with Lattice Diamond.
