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 M2GL090 has about 15% more logic capacity (86.2K vs 74.6K LUT4 equivalents).
They use different logic architectures: the M2GL090 is built from LUT4 and the XC6SLX75T from LUT6, so the raw LUT counts (86.2K vs 46.6K) are not directly comparable.
For arithmetic, the XC6SLX75T has 132 DSP48A1 slices against 84 18×18 math blocks (MACC) on the M2GL090.
The XC6SLX75T has more on-chip memory (3 Mb vs 1.9 Mb).
Both have transceivers: 4 at up to 5 Gb/s on the M2GL090 and 8 at up to 3.2 Gb/s on the XC6SLX75T.
Configuration memory: non-volatile (flash) on the M2GL090, sram on the XC6SLX75T.
The M2GL090 is designed with Microchip Libero SoC and the XC6SLX75T with AMD ISE Design Suite.
