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 CCGM1A25 has about 1771% more logic capacity (1024K vs 54.7K LUT4 equivalents).
They use different logic architectures: the CCGM1A25 is built from CPEs and the GW2AN-55 from LUT4, so the raw LUT counts (512K vs 54.7K) are not directly comparable.
The CCGM1A25 has more on-chip memory (31.2 Mb vs 2.5 Mb).
Only the CCGM1A25 has multi-gigabit transceivers (25 5 Gb/s).
The CCGM1A25 is designed with Yosys + nextpnr (open source) and the GW2AN-55 with Gowin EDA.
