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 EP4CGX50 has about 39% more logic capacity (50K vs 36.1K LUT4 equivalents).
They use different logic architectures: the EP2AGX45 is built from ALMs and the EP4CGX50 from LUT4, so the raw LUT counts (18.1K vs 50K) are not directly comparable.
For arithmetic, the EP2AGX45 has 232 18×18 multipliers against 140 18×18 multipliers on the EP4CGX50.
The EP2AGX45 has more on-chip memory (2.8 Mb vs 2.4 Mb).
Both have transceivers: 8 at up to 6.375 Gb/s on the EP2AGX45 and 8 at up to 3.125 Gb/s on the EP4CGX50.
The EP2AGX45 is designed with Altera Quartus Prime and the EP4CGX50 with Altera Quartus Prime.
