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

Both devices offer similar logic capacity: 899K and 899K LUT4 equivalents.

Both have transceivers: 48 at up to 28.3 Gb/s on the SX 1100 and 72 at up to 57.8 Gb/s on the TX 1100.

The SX 1100 is designed with Altera Quartus Prime and the TX 1100 with Altera Quartus Prime.
