Highlighted values are higher. LUT counts are shown as published; the LUT4 equivalent is an approximation to compare different LUT types, see how FPGA vendors count logic. Add up to two more devices to this comparison.
Key differences
The LFE3-35EA has about 23% more logic capacity (33K vs 26.9K LUT4 equivalents).
They use different logic architectures: the 5CGXC3 is built from ALMs and the LFE3-35EA from LUT4, so the raw LUT counts (13.5K vs 33K) are not directly comparable.
For arithmetic, the LFE3-35EA has 64 18×18 multipliers against 57 variable-precision DSP blocks on the 5CGXC3.
Both have transceivers: 3 at up to 3.125 Gb/s on the 5CGXC3 and 4 at up to 3.2 Gb/s on the LFE3-35EA.
The 5CGXC3 is designed with Altera Quartus Prime; open source: Yosys + nextpnr-mistral (experimental) with Mistral and the LFE3-35EA with Lattice Diamond.
