Key differences
The XC7K480T has about 20% more logic capacity (478K vs 397K LUT4 equivalents).
They use different logic architectures: the LAV-AT-G70 is built from LUT4 and the XC7K480T from LUT6, so the raw LUT counts (397K vs 299K) are not directly comparable.
For arithmetic, the XC7K480T has 1,920 DSP slices against 1,800 18×18 multipliers on the LAV-AT-G70.
The LAV-AT-G70 is designed with Lattice Radiant and the XC7K480T with AMD Vivado.
