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 CCGM1A2 has about 50% more logic capacity (81.9K vs 54.7K LUT4 equivalents).
They use different logic architectures: the CCGM1A2 is built from CPEs and the GW2AN-55 from LUT4, so the raw LUT counts (41K vs 54.7K) are not directly comparable.
Only the CCGM1A2 has multi-gigabit transceivers (2 5 Gb/s).
The CCGM1A2 is designed with Yosys + nextpnr (open source) and the GW2AN-55 with Gowin EDA.
