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: 525K and 554K LUT4 equivalents.
They use different logic architectures: the 5SGSD8 is built from ALMs and the XC7VX550T from LUT6, so the raw LUT counts (262K vs 346K) are not directly comparable.
For arithmetic, the XC7VX550T has 2,880 DSP slices against 1,963 variable-precision DSP blocks on the 5SGSD8.
The 5SGSD8 has more on-chip memory (50.1 Mb vs 41.5 Mb).
Both have transceivers: 48 at up to 14.1 Gb/s on the 5SGSD8 and 80 at up to 13.1 Gb/s on the XC7VX550T.
The 5SGSD8 is designed with Altera Quartus Prime and the XC7VX550T with AMD Vivado.
