Key differences
Both devices offer similar logic capacity: 55.8K and 52.2K LUT4 equivalents.
They use different logic architectures: the Tz50 is built from LUT4 and the XC7S50 from LUT6, so the raw LUT counts (55.8K vs 32.6K) are not directly comparable.
For arithmetic, the Tz50 has 140 DSP blocks against 120 DSP slices on the XC7S50.
The Tz50 is designed with Efinix Efinity and the XC7S50 with AMD Vivado.
