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 XC6SLX25 has about 16% more logic capacity (24.1K vs 20.7K LUT4 equivalents).
They use different logic architectures: the GW2A-18 is built from LUT4 and the XC6SLX25 from LUT6, so the raw LUT counts (20.7K vs 15K) are not directly comparable.
For arithmetic, the GW2A-18 has 48 18×18 multipliers against 38 DSP48A1 slices on the XC6SLX25.
The XC6SLX25 has more on-chip memory (0.9 Mb vs 0.8 Mb).
The GW2A-18 is designed with Gowin EDA; open source: Yosys + nextpnr-himbaechel with Project Apicula and the XC6SLX25 with AMD ISE Design Suite.
