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
Both devices offer similar logic capacity: 2892K and 2806K LUT4 equivalents.
They use different logic architectures: the A27F045 is built from ALMs and the XCVH1522 from LUT6, so the raw LUT counts (1446K vs 1754K) are not directly comparable.
For arithmetic, the XCVH1522 has 7,392 DSP Engines against 5,540 AI Tensor DSP blocks on the A27F045.
Both have transceivers: 72 at up to 256 Gb/s on the A27F045 and 88 at up to 58 Gb/s on the XCVH1522.
The A27F045 is designed with Altera Quartus Prime and the XCVH1522 with AMD Vivado.
