Key differences
The XC7K420T has about 15% more logic capacity (417K vs 364K LUT4 equivalents).
They use different logic architectures: the 10AX048 is built from ALMs and the XC7K420T from LUT6, so the raw LUT counts (182K vs 261K) are not directly comparable.
For arithmetic, the XC7K420T has 1,680 DSP slices against 1,368 variable-precision DSP blocks on the 10AX048.
Both have transceivers: 36 at up to 17.4 Gb/s on the 10AX048 and 32 at up to 12.5 Gb/s on the XC7K420T.
The 10AX048 is designed with Altera Quartus Prime and the XC7K420T with AMD Vivado.
