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 XC6VHX565T has about 33% more logic capacity (567K vs 425K LUT4 equivalents).

They use different logic architectures: the EP4S100G5 is built from ALMs and the XC6VHX565T from LUT6, so the raw LUT counts (212K vs 354K) are not directly comparable.

For arithmetic, the EP4S100G5 has 1,024 18×18 multipliers against 864 DSP48E1 slices on the XC6VHX565T.

The XC6VHX565T has more on-chip memory (32.1 Mb vs 20.2 Mb).

Both have transceivers: 48 at up to 11.3 Gb/s on the EP4S100G5 and 72 at up to 11.18 Gb/s on the XC6VHX565T.

The EP4S100G5 is designed with Altera Quartus Prime and the XC6VHX565T with AMD ISE Design Suite.
