Key differences
The 5CSXC4 has about 38% more logic capacity (31.8K vs 23K LUT4 equivalents).
They use different logic architectures: the 5CSXC4 is built from ALMs and the MPFS025T from LUT4, so the raw LUT counts (15.9K vs 23K) are not directly comparable.
For arithmetic, the 5CSXC4 has 84 variable-precision DSP blocks against 68 18×18 math blocks (MACC) on the MPFS025T.
The 5CSXC4 has more on-chip memory (2.6 Mb vs 1.6 Mb).
Both have transceivers: 6 at up to 3.125 Gb/s on the 5CSXC4 and 4 at up to 12.5 Gb/s on the MPFS025T.
Configuration memory: sram on the 5CSXC4, non-volatile (sonos flash) on the MPFS025T.
The 5CSXC4 is designed with Altera Quartus Prime and the MPFS025T with Microchip Libero SoC.
