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 XCKU095 has about 91% more logic capacity (860K vs 451K LUT4 equivalents).
They use different logic architectures: the 5SGXB6 is built from ALMs and the XCKU095 from LUT6, so the raw LUT counts (225K vs 538K) are not directly comparable.
For arithmetic, the XCKU095 has 768 DSP slices against 399 variable-precision DSP blocks on the 5SGXB6.
The XCKU095 has more on-chip memory (59.1 Mb vs 52 Mb).
Both have transceivers: 66 at up to 14.1 Gb/s on the 5SGXB6 and 64 at up to 16.3 Gb/s on the XCKU095.
The 5SGXB6 is designed with Altera Quartus Prime and the XCKU095 with AMD Vivado.
