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 LAV-AT-G70 has about 15% more logic capacity (397K vs 345K LUT4 equivalents).
They use different logic architectures: the 5SGSD5 is built from ALMs and the LAV-AT-G70 from LUT4, so the raw LUT counts (173K vs 397K) are not directly comparable.
For arithmetic, the LAV-AT-G70 has 1,800 18×18 multipliers against 1,590 variable-precision DSP blocks on the 5SGSD5.
Both have transceivers: 36 at up to 14.1 Gb/s on the 5SGSD5 and 28 at up to 12.5 Gb/s on the LAV-AT-G70.
The 5SGSD5 is designed with Altera Quartus Prime and the LAV-AT-G70 with Lattice Radiant.
