Key differences
The Ti35 has about 52% more logic capacity (35.5K vs 23.4K LUT4 equivalents).
They use different logic architectures: the Ti35 is built from LUT4 and the XC7S25 from LUT6, so the raw LUT counts (35.5K vs 14.6K) are not directly comparable.
For arithmetic, the Ti35 has 93 DSP blocks against 80 DSP slices on the XC7S25.
The Ti35 is designed with Efinix Efinity and the XC7S25 with AMD Vivado.
