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
Both devices offer similar logic capacity: 23K and 24.1K LUT4 equivalents.
They use different logic architectures: the GW5A-25 is built from LUT4 and the XC6SLX25 from LUT6, so the raw LUT counts (23K vs 15K) are not directly comparable.
For arithmetic, the XC6SLX25 has 38 DSP48A1 slices against 28 27×18 DSP blocks on the GW5A-25.
The GW5A-25 is designed with Gowin EDA; open source: Yosys + nextpnr-himbaechel with Project Apicula and the XC6SLX25 with AMD ISE Design Suite.
