Key differences
Both devices offer similar logic capacity: 23K and 23.4K LUT4 equivalents.
They use different logic architectures: the GW3A-20 is built from LUT4 and the XC7S25 from LUT6, so the raw LUT counts (23K vs 14.6K) are not directly comparable.
For arithmetic, the XC7S25 has 80 DSP slices against 52 DSP blocks on the GW3A-20.
The GW3A-20 has more on-chip memory (2.1 Mb vs 1.6 Mb).
The GW3A-20 is designed with Gowin EDA and the XC7S25 with AMD Vivado.
