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 XC6VLX195T has about 12% more logic capacity (200K vs 178K LUT4 equivalents).
They use different logic architectures: the 5SGSD3 is built from ALMs and the XC6VLX195T from LUT6, so the raw LUT counts (89K vs 125K) are not directly comparable.
For arithmetic, the XC6VLX195T has 640 DSP48E1 slices against 600 variable-precision DSP blocks on the 5SGSD3.
Both have transceivers: 24 at up to 14.1 Gb/s on the 5SGSD3 and 20 at up to 6.6 Gb/s on the XC6VLX195T.
The 5SGSD3 is designed with Altera Quartus Prime and the XC6VLX195T with AMD ISE Design Suite.
