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 5SGXA4 has about 24% more logic capacity (317K vs 256K LUT4 equivalents).
For arithmetic, the GX 400 has 648 variable-precision DSP blocks against 256 variable-precision DSP blocks on the 5SGXA4.
The 5SGXA4 has more on-chip memory (37.1 Mb vs 30 Mb).
Both have transceivers: 36 at up to 14.1 Gb/s on the 5SGXA4 and 24 at up to 28.3 Gb/s on the GX 400.
The 5SGXA4 is designed with Altera Quartus Prime and the GX 400 with Altera Quartus Prime.
