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 XC7K160T has about 23% more logic capacity (162K vs 132K LUT4 equivalents).
They use different logic architectures: the Mach-N2 MH21D is built from LUT4 and the XC7K160T from LUT6, so the raw LUT counts (132K vs 101K) are not directly comparable.
For arithmetic, the XC7K160T has 600 DSP slices against 520 18×18 multipliers on the Mach-N2 MH21D.
Both have transceivers: 4 at up to 16 Gb/s on the Mach-N2 MH21D and 8 at up to 12.5 Gb/s on the XC7K160T.
Configuration memory: internal flash on the Mach-N2 MH21D, sram on the XC7K160T.
The Mach-N2 MH21D is designed with Lattice Radiant and the XC7K160T with AMD Vivado; open source: openXC7 (experimental) with Project X-Ray.
