Key differences
The XC7A35T has about 15% more logic capacity (33.3K vs 29K LUT4 equivalents).
They use different logic architectures: the EP4CGX30 is built from LUT4 and the XC7A35T from LUT6, so the raw LUT counts (29K vs 20.8K) are not directly comparable.
For arithmetic, the XC7A35T has 90 DSP slices against 80 18×18 multipliers on the EP4CGX30.
The XC7A35T has more on-chip memory (1.8 Mb vs 1.1 Mb).
Both have transceivers: 4 at up to 3.125 Gb/s on the EP4CGX30 and 4 at up to 6.6 Gb/s on the XC7A35T.
The EP4CGX30 is designed with Altera Quartus Prime and the XC7A35T with AMD Vivado.
