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 XC6SLX9 has about 14% more logic capacity (9.2K vs 8K LUT4 equivalents).

They use different logic architectures: the LFXP2-8E is built from LUT4 and the XC6SLX9 from LUT6, so the raw LUT counts (8K vs 5.7K) are not directly comparable.

The XC6SLX9 has more on-chip memory (0.6 Mb vs 0.2 Mb).

Configuration memory: internal flash on the LFXP2-8E, sram on the XC6SLX9.

The LFXP2-8E is designed with Lattice Diamond and the XC6SLX9 with AMD ISE Design Suite.
