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 CCGM1A4 has about 1070% more logic capacity (164K vs 14K LUT4 equivalents).
They use different logic architectures: the CCGM1A4 is built from CPEs and the EP4CGX15 from LUT4, so the raw LUT counts (81.9K vs 14K) are not directly comparable.
The CCGM1A4 has more on-chip memory (5 Mb vs 0.5 Mb).
Both have transceivers: 4 at up to 5 Gb/s on the CCGM1A4 and 2 at up to 3.125 Gb/s on the EP4CGX15.
The CCGM1A4 is designed with Yosys + nextpnr (open source) and the EP4CGX15 with Altera Quartus Prime.
