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 Ti660 has about 29% more logic capacity (657K vs 509K LUT4 equivalents).
They use different logic architectures: the Ti660 is built from LUT4 and the XC2VM3654 from LUT6, so the raw LUT counts (— vs 318K) are not directly comparable.
For arithmetic, the XC2VM3654 has 1,428 DSP Engines against 1,260 DSP blocks on the Ti660.
The XC2VM3654 has more on-chip memory (45.5 Mb vs 38.9 Mb).
Both have transceivers: 24 at up to 25.8 Gb/s on the Ti660 and 24 at up to 32.75 Gb/s on the XC2VM3654.
The Ti660 is designed with Efinix Efinity and the XC2VM3654 with AMD Vivado.
