Highlighted values are higher. LUT counts are shown as published; the LUT4 equivalent is an approximation to compare different LUT types, see how FPGA vendors count logic. Add up to two more devices to this comparison.
Key differences
The Ti375 has about 26% more logic capacity (363K vs 288K LUT4 equivalents).
They use different logic architectures: the Ti375 is built from LUT4 and the XCZU63DR from LUT6, so the raw LUT counts (363K vs 180K) are not directly comparable.
For arithmetic, the Ti375 has 1,344 DSP blocks against 1,200 DSP slices on the XCZU63DR.
The XCZU63DR has more on-chip memory (54.2 Mb vs 27.5 Mb).
Both have transceivers: 16 at up to 16 Gb/s on the Ti375 and 4 at up to 28.21 Gb/s on the XCZU63DR.
The Ti375 is designed with Efinix Efinity and the XCZU63DR with AMD Vivado.
