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 5SEE9 has about 60% more logic capacity (634K vs 397K LUT4 equivalents).

They use different logic architectures: the 5SEE9 is built from ALMs and the LAV-AT-E70 from LUT4, so the raw LUT counts (317K vs 397K) are not directly comparable.

For arithmetic, the LAV-AT-E70 has 1,800 18×18 multipliers against 352 variable-precision DSP blocks on the 5SEE9.

The 5SEE9 has more on-chip memory (51.6 Mb vs 35.6 Mb).

The 5SEE9 is designed with Altera Quartus Prime and the LAV-AT-E70 with Lattice Radiant.
