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 XC7K70T has about 30% more logic capacity (65.6K vs 50.6K LUT4 equivalents).
They use different logic architectures: the EP2AGX65 is built from ALMs and the XC7K70T from LUT6, so the raw LUT counts (25.3K vs 41K) are not directly comparable.
For arithmetic, the EP2AGX65 has 312 18×18 multipliers against 240 DSP slices on the XC7K70T.
Both have transceivers: 8 at up to 6.375 Gb/s on the EP2AGX65 and 8 at up to 12.5 Gb/s on the XC7K70T.
The EP2AGX65 is designed with Altera Quartus Prime and the XC7K70T with AMD Vivado; open source: openXC7 (experimental) with Project X-Ray.
