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 XC6VLX550T has about 29% more logic capacity (550K vs 425K LUT4 equivalents).
They use different logic architectures: the EP4S100G5 is built from ALMs and the XC6VLX550T from LUT6, so the raw LUT counts (212K vs 344K) are not directly comparable.
For arithmetic, the EP4S100G5 has 1,024 18×18 multipliers against 864 DSP48E1 slices on the XC6VLX550T.
Both have transceivers: 48 at up to 11.3 Gb/s on the EP4S100G5 and 36 at up to 6.6 Gb/s on the XC6VLX550T.
The EP4S100G5 is designed with Altera Quartus Prime and the XC6VLX550T with AMD ISE Design Suite.
