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 XC2VM3654 has about 23% more logic capacity (509K vs 415K LUT4 equivalents).

They use different logic architectures: the SX 650 is built from ALMs and the XC2VM3654 from LUT6, so the raw LUT counts (207K vs 318K) are not directly comparable.

For arithmetic, the XC2VM3654 has 1,428 DSP Engines against 1,152 variable-precision DSP blocks on the SX 650.

Both have transceivers: 24 at up to 28.3 Gb/s on the SX 650 and 24 at up to 32.75 Gb/s on the XC2VM3654.

The SX 650 is designed with Altera Quartus Prime and the XC2VM3654 with AMD Vivado.
