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 XCAU15P has about 26% more logic capacity (125K vs 99.3K LUT4 equivalents).
They use different logic architectures: the EP2AGX125 is built from ALMs and the XCAU15P from LUT6, so the raw LUT counts (49.6K vs 78K) are not directly comparable.
The EP2AGX125 has more on-chip memory (6.4 Mb vs 5.1 Mb).
Both have transceivers: 12 at up to 6.375 Gb/s on the EP2AGX125 and 12 at up to 16.3 Gb/s on the XCAU15P.
The EP2AGX125 is designed with Altera Quartus Prime and the XCAU15P with AMD Vivado.
