Highlighted values are higher. Logic is compared in LUT4 equivalents; see how FPGA vendors count logic.
Key differences
Both devices offer similar logic capacity: 349K and 350K LUT4 equivalents.
They use different logic architectures: the Tz325 is built from LUT4 and the XC7Z045 from LUT6, so the raw LUT counts (349K vs 219K) are not directly comparable.
For arithmetic, the Tz325 has 1,008 DSP blocks against 900 DSP slices on the XC7Z045.
The Tz325 is designed with Efinix Efinity and the XC7Z045 with AMD Vivado.
