Key differences
The MPFS460T has about 34% more logic capacity (461K vs 344K LUT4 equivalents).
They use different logic architectures: the MPFS460T is built from LUT4 and the XCZU6EG from LUT6, so the raw LUT counts (461K vs 215K) are not directly comparable.
For arithmetic, the XCZU6EG has 1,973 DSP slices against 1,420 18×18 math blocks (MACC) on the MPFS460T.
The MPFS460T has more on-chip memory (28.5 Mb vs 25.1 Mb).
Both have transceivers: 20 at up to 12.5 Gb/s on the MPFS460T and 24 at up to 16.3 Gb/s on the XCZU6EG.
Configuration memory: non-volatile (sonos flash) on the MPFS460T, sram on the XCZU6EG.
The MPFS460T is designed with Microchip Libero SoC and the XCZU6EG with AMD Vivado.
