Key differences
The EP4CGX22 has about 64% more logic capacity (21K vs 12.8K LUT4 equivalents).
They use different logic architectures: the EP4CGX22 is built from LUT4 and the XC7A12T from LUT6, so the raw LUT counts (21K vs 8K) are not directly comparable.
Both have transceivers: 4 at up to 3.125 Gb/s on the EP4CGX22 and 2 at up to 6.6 Gb/s on the XC7A12T.
The EP4CGX22 is designed with Altera Quartus Prime and the XC7A12T with AMD Vivado.
