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 5CGXC7 has about 23% more logic capacity (113K vs 92K LUT4 equivalents).
They use different logic architectures: the 5CGXC7 is built from ALMs and the LFE3-95EA from LUT4, so the raw LUT counts (56.5K vs 92K) are not directly comparable.
For arithmetic, the 5CGXC7 has 156 variable-precision DSP blocks against 128 18×18 multipliers on the LFE3-95EA.
The 5CGXC7 has more on-chip memory (6.7 Mb vs 4.3 Mb).
Both have transceivers: 9 at up to 3.125 Gb/s on the 5CGXC7 and 12 at up to 3.2 Gb/s on the LFE3-95EA.
The 5CGXC7 is designed with Altera Quartus Prime; open source: Yosys + nextpnr-mistral (experimental) with Mistral and the LFE3-95EA with Lattice Diamond.
