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 CCGM1A1 has about 98% more logic capacity (41K vs 20.7K LUT4 equivalents).
They use different logic architectures: the CCGM1A1 is built from CPEs and the GW2AN-18X from LUT4, so the raw LUT counts (20.5K vs 20.7K) are not directly comparable.
The CCGM1A1 has more on-chip memory (1.2 Mb vs 0.5 Mb).
Only the CCGM1A1 has multi-gigabit transceivers (1 5 Gb/s).
The CCGM1A1 is designed with Yosys + nextpnr (open source) and the GW2AN-18X with Gowin EDA.
