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 5AGXB5 has about 17% more logic capacity (317K vs 272K LUT4 equivalents).

For arithmetic, the 5AGXB5 has 1,092 variable-precision DSP blocks against 1,044 variable-precision DSP blocks on the 5SGSD4.

Both have transceivers: 36 at up to 6.5536 Gb/s on the 5AGXB5 and 36 at up to 14.1 Gb/s on the 5SGSD4.

The 5AGXB5 is designed with Altera Quartus Prime and the 5SGSD4 with Altera Quartus Prime.
