Key differences
The 5CGXC3 has about 62% more logic capacity (26.9K vs 16.6K LUT4 equivalents).
They use different logic architectures: the 5CGXC3 is built from ALMs and the XC7A15T from LUT6, so the raw LUT counts (13.5K vs 10.4K) are not directly comparable.
For arithmetic, the 5CGXC3 has 57 variable-precision DSP blocks against 45 DSP slices on the XC7A15T.
The 5CGXC3 has more on-chip memory (1.3 Mb vs 0.9 Mb).
Both have transceivers: 3 at up to 3.125 Gb/s on the 5CGXC3 and 4 at up to 6.6 Gb/s on the XC7A15T.
The 5CGXC3 is designed with Altera Quartus Prime and the XC7A15T with AMD Vivado.
