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 Certus-N2 CT20 has about 15% more logic capacity (135K vs 118K LUT4 equivalents).
They use different logic architectures: the 5AGXA3 is built from ALMs and the Certus-N2 CT20 from LUT4, so the raw LUT counts (58.9K vs 135K) are not directly comparable.
For arithmetic, the Certus-N2 CT20 has 520 18×18 multipliers against 396 variable-precision DSP blocks on the 5AGXA3.
The Certus-N2 CT20 has more on-chip memory (12 Mb vs 10.3 Mb).
Both have transceivers: 9 at up to 6.5536 Gb/s on the 5AGXA3 and 8 at up to 16 Gb/s on the Certus-N2 CT20.
The 5AGXA3 is designed with Altera Quartus Prime and the Certus-N2 CT20 with Lattice Radiant.
