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 5CGXC9 has about 14% more logic capacity (227K vs 200K LUT4 equivalents).
They use different logic architectures: the 5CGXC9 is built from ALMs and the XC6VLX195T from LUT6, so the raw LUT counts (114K vs 125K) are not directly comparable.
For arithmetic, the XC6VLX195T has 640 DSP48E1 slices against 342 variable-precision DSP blocks on the 5CGXC9.
Both have transceivers: 12 at up to 3.125 Gb/s on the 5CGXC9 and 20 at up to 6.6 Gb/s on the XC6VLX195T.
The 5CGXC9 is designed with Altera Quartus Prime; open source: Yosys + nextpnr-mistral (experimental) with Mistral and the XC6VLX195T with AMD ISE Design Suite.
