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

Key differences

The XCSU35P has about 11% more logic capacity (25.6K vs 23K LUT4 equivalents).

They use different logic architectures: the GW3A-20 is built from LUT4 and the XCSU35P from LUT6, so the raw LUT counts (23K vs 16K) are not directly comparable.

For arithmetic, the GW3A-20 has 52 DSP blocks against 48 DSP slices on the XCSU35P.

The GW3A-20 has more on-chip memory (2.1 Mb vs 1.7 Mb).

The GW3A-20 is designed with Gowin EDA and the XCSU35P with AMD Vivado.
