Key differences
The EP4CGX75 has about 13% more logic capacity (74K vs 65.6K LUT4 equivalents).
They use different logic architectures: the EP4CGX75 is built from LUT4 and the XC7K70T from LUT6, so the raw LUT counts (74K vs 41K) are not directly comparable.
For arithmetic, the XC7K70T has 240 DSP slices against 198 18×18 multipliers on the EP4CGX75.
The XC7K70T has more on-chip memory (4.7 Mb vs 4.1 Mb).
Both have transceivers: 8 at up to 3.125 Gb/s on the EP4CGX75 and 8 at up to 12.5 Gb/s on the XC7K70T.
The EP4CGX75 is designed with Altera Quartus Prime and the XC7K70T with AMD Vivado.
