Key differences
The XC7A100T has about 37% more logic capacity (101K vs 74K LUT4 equivalents).
They use different logic architectures: the EP4CGX75 is built from LUT4 and the XC7A100T from LUT6, so the raw LUT counts (74K vs 63.4K) are not directly comparable.
For arithmetic, the XC7A100T has 240 DSP slices against 198 18×18 multipliers on the EP4CGX75.
The XC7A100T 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 6.6 Gb/s on the XC7A100T.
The EP4CGX75 is designed with Altera Quartus Prime and the XC7A100T with AMD Vivado.
