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 LFXP2-5E has about 9% more logic capacity (5K vs 4.6K LUT4 equivalents).
For arithmetic, the GW1NSR-4C has 16 18×18 multipliers against 12 18×18 multipliers on the LFXP2-5E.
The GW1NSR-4C has more on-chip memory (0.2 Mb vs 0.2 Mb).
The GW1NSR-4C includes a hard Cortex-M3 processor, while the LFXP2-5E does not.
Configuration memory: embedded flash on the GW1NSR-4C, internal flash on the LFXP2-5E.
The GW1NSR-4C is designed with Gowin EDA; open source: Yosys + nextpnr-himbaechel with Project Apicula and the LFXP2-5E with Lattice Diamond.
