Key differences
The EP4CGX22 has about 26% more logic capacity (21K vs 16.6K LUT4 equivalents).
They use different logic architectures: the EP4CGX22 is built from LUT4 and the XC7A15T from LUT6, so the raw LUT counts (21K vs 10.4K) are not directly comparable.
For arithmetic, the XC7A15T has 45 DSP slices against 40 18×18 multipliers on the EP4CGX22.
The XC7A15T has more on-chip memory (0.9 Mb vs 0.7 Mb).
Both have transceivers: 4 at up to 3.125 Gb/s on the EP4CGX22 and 4 at up to 6.6 Gb/s on the XC7A15T.
The EP4CGX22 is designed with Altera Quartus Prime and the XC7A15T with AMD Vivado.
