Key differences
Both devices offer similar logic capacity: 397K and 412K LUT4 equivalents.
They use different logic architectures: the LAV-AT-G70 is built from LUT4 and the XC7VX415T from LUT6, so the raw LUT counts (397K vs 258K) are not directly comparable.
For arithmetic, the XC7VX415T has 2,160 DSP slices against 1,800 18×18 multipliers on the LAV-AT-G70.
The LAV-AT-G70 has more on-chip memory (35.6 Mb vs 30.9 Mb).
Both have transceivers: 28 at up to 12.5 Gb/s on the LAV-AT-G70 and 48 at up to 13.1 Gb/s on the XC7VX415T.
The LAV-AT-G70 is designed with Lattice Radiant and the XC7VX415T with AMD Vivado.
