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 5SGTC5 has about 25% more logic capacity (321K vs 256K LUT4 equivalents).

For arithmetic, the GX 400 has 648 variable-precision DSP blocks against 256 variable-precision DSP blocks on the 5SGTC5.

The 5SGTC5 has more on-chip memory (45 Mb vs 30 Mb).

Both have transceivers: 36 at up to 28.05 Gb/s on the 5SGTC5 and 24 at up to 28.3 Gb/s on the GX 400.

The 5SGTC5 is designed with Altera Quartus Prime and the GX 400 with Altera Quartus Prime.
