Key differences
The GX 650 has about 39% more logic capacity (415K vs 299K LUT4 equivalents).
They use different logic architectures: the GX 650 is built from ALMs and the XC2KU040P from LUT6, so the raw LUT counts (207K vs 187K) are not directly comparable.
For arithmetic, the XC2KU040P has 1,560 DSP slices against 1,152 variable-precision DSP blocks on the GX 650.
The GX 650 has more on-chip memory (49 Mb vs 37.3 Mb).
Both have transceivers: 24 at up to 28.3 Gb/s on the GX 650 and 16 at up to 32.75 Gb/s on the XC2KU040P.
The GX 650 is designed with Altera Quartus Prime and the XC2KU040P with AMD Vivado.
