Key differences
Both devices offer similar logic capacity: 501K and 486K LUT4 equivalents.
They use different logic architectures: the 10AX066 is built from ALMs and the XC7VX485T from LUT6, so the raw LUT counts (251K vs 304K) are not directly comparable.
For arithmetic, the XC7VX485T has 2,800 DSP slices against 1,687 variable-precision DSP blocks on the 10AX066.
The 10AX066 has more on-chip memory (41.7 Mb vs 36.2 Mb).
Both have transceivers: 48 at up to 17.4 Gb/s on the 10AX066 and 56 at up to 12.5 Gb/s on the XC7VX485T.
The 10AX066 is designed with Altera Quartus Prime and the XC7VX485T with AMD Vivado.
