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 5CGXC7 has about 12% more logic capacity (113K vs 101K LUT4 equivalents).
They use different logic architectures: the 5CGXC7 is built from ALMs and the XC6SLX100T from LUT6, so the raw LUT counts (56.5K vs 63.3K) are not directly comparable.
For arithmetic, the XC6SLX100T has 180 DSP48A1 slices against 156 variable-precision DSP blocks on the 5CGXC7.
The 5CGXC7 has more on-chip memory (6.7 Mb vs 4.7 Mb).
Both have transceivers: 9 at up to 3.125 Gb/s on the 5CGXC7 and 8 at up to 3.2 Gb/s on the XC6SLX100T.
The 5CGXC7 is designed with Altera Quartus Prime; open source: Yosys + nextpnr-mistral (experimental) with Mistral and the XC6SLX100T with AMD ISE Design Suite.
