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 A27F070 has about 10% more logic capacity (4531K vs 4119K LUT4 equivalents).
They use different logic architectures: the A27F070 is built from ALMs and the XCVH1742 from LUT6, so the raw LUT counts (2266K vs 2574K) are not directly comparable.
For arithmetic, the XCVH1742 has 10,848 DSP Engines against 8,316 AI Tensor DSP blocks on the A27F070.
The A27F070 has more on-chip memory (758 Mb vs 673 Mb).
Both have transceivers: 80 at up to 128 Gb/s on the A27F070 and 128 at up to 58 Gb/s on the XCVH1742.
The A27F070 is designed with Altera Quartus Prime and the XCVH1742 with AMD Vivado.
