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 7214% more logic capacity (1024K vs 14K LUT4 equivalents).
They use different logic architectures: the CCGM1A25 is built from CPEs and the EP4CGX15 from LUT4, so the raw LUT counts (512K vs 14K) are not directly comparable.
The CCGM1A25 has more on-chip memory (31.2 Mb vs 0.5 Mb).
Both have transceivers: 25 at up to 5 Gb/s on the CCGM1A25 and 2 at up to 3.125 Gb/s on the EP4CGX15.
The CCGM1A25 is designed with Yosys + nextpnr-himbaechel with Project Peppercorn (open source) and the EP4CGX15 with Altera Quartus Prime.
