Highlighted values are higher. Logic is compared in LUT4 equivalents; see how FPGA vendors count logic.

Key differences

Both devices offer similar logic capacity: 1.2K and 1.1K LUT4 equivalents.

For arithmetic, the iCE5LP1K has 2 16×16 MAC blocks against no 18×18 multipliers on the GW1NZ-1.

The GW1NZ-1 has more on-chip memory (0.1 Mb vs 0.1 Mb).

Configuration memory: embedded flash on the GW1NZ-1, nvcm on the iCE5LP1K.

The GW1NZ-1 is designed with Gowin EDA and the iCE5LP1K with Lattice iCEcube2.
