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 GW2AN-55 has about 34% more logic capacity (54.7K vs 41K LUT4 equivalents).
They use different logic architectures: the CCGM1A1 is built from CPEs and the GW2AN-55 from LUT4, so the raw LUT counts (20.5K vs 54.7K) are not directly comparable.
The GW2AN-55 has more on-chip memory (2.5 Mb vs 1.2 Mb).
Only the CCGM1A1 has multi-gigabit transceivers (1 5 Gb/s).
The CCGM1A1 is designed with Yosys + nextpnr (open source) and the GW2AN-55 with Gowin EDA.
