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

Both devices offer similar logic capacity: 272K and 283K LUT4 equivalents.

For arithmetic, the 5SGSD4 has 1,044 variable-precision DSP blocks against 1,040 18×18 multipliers on the EP4SGX360.

Both have transceivers: 36 at up to 14.1 Gb/s on the 5SGSD4 and 48 at up to 8.5 Gb/s on the EP4SGX360.

The 5SGSD4 is designed with Altera Quartus Prime and the EP4SGX360 with Altera Quartus Prime.
