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 XC6VSX475T has about 8% more logic capacity (476K vs 440K LUT4 equivalents).
They use different logic architectures: the 5SGSD6 is built from ALMs and the XC6VSX475T from LUT6, so the raw LUT counts (220K vs 298K) are not directly comparable.
For arithmetic, the XC6VSX475T has 2,016 DSP48E1 slices against 1,775 variable-precision DSP blocks on the 5SGSD6.
The 5SGSD6 has more on-chip memory (45.3 Mb vs 37.4 Mb).
Both have transceivers: 48 at up to 14.1 Gb/s on the 5SGSD6 and 36 at up to 6.6 Gb/s on the XC6VSX475T.
The 5SGSD6 is designed with Altera Quartus Prime and the XC6VSX475T with AMD ISE Design Suite.
