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.

The TX 2500 has about 21% more logic capacity (1642K vs 1359K LUT4 equivalents).

For arithmetic, the TX 2500 has 5,011 variable-precision DSP blocks against 3,744 variable-precision DSP blocks on the SX 2100.

The TX 2500 has more on-chip memory (195 Mb vs 127 Mb).

Both have transceivers: 96 at up to 28.3 Gb/s on the SX 2100 and 144 at up to 57.8 Gb/s on the TX 2500.

The SX 2100 is designed with Altera Quartus Prime and the TX 2500 with Altera Quartus Prime.
