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 EP4SE820 has about 155% more logic capacity (650K vs 255K LUT4 equivalents).
They use different logic architectures: the EP4SE820 is built from ALMs and the LAV-AT-E50 from LUT4, so the raw LUT counts (325K vs 255K) are not directly comparable.
For arithmetic, the LAV-AT-E50 has 1,120 18×18 multipliers against 960 18×18 multipliers on the EP4SE820.
The EP4SE820 is designed with Altera Quartus Prime and the LAV-AT-E50 with Lattice Radiant.
