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 A27F120 has about 89% more logic capacity (7770K vs 4119K LUT4 equivalents).
They use different logic architectures: the A27F120 is built from ALMs and the XCVH1742 from LUT6, so the raw LUT counts (3885K vs 2574K) are not directly comparable.
For arithmetic, the A27F120 has 13,718 AI Tensor DSP blocks against 10,848 DSP Engines on the XCVH1742.
The A27F120 has more on-chip memory (1328 Mb vs 673 Mb).
Both have transceivers: 144 at up to 256 Gb/s on the A27F120 and 128 at up to 58 Gb/s on the XCVH1742.
The A27F120 is designed with Altera Quartus Prime and the XCVH1742 with AMD Vivado.
