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 EP2AGX260 has about 18% more logic capacity (205K vs 174K LUT4 equivalents).
They use different logic architectures: the EP2AGX260 is built from ALMs and the XCAU20P from LUT6, so the raw LUT counts (103K vs 109K) are not directly comparable.
For arithmetic, the XCAU20P has 900 DSP slices against 736 18×18 multipliers on the EP2AGX260.
The EP2AGX260 has more on-chip memory (8.3 Mb vs 7 Mb).
Both have transceivers: 16 at up to 6.375 Gb/s on the EP2AGX260 and 12 at up to 32.75 Gb/s on the XCAU20P.
The EP2AGX260 is designed with Altera Quartus Prime and the XCAU20P with AMD Vivado.
