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 XC6SLX25 has about 22% more logic capacity (24.1K vs 19.7K LUT4 equivalents).
They use different logic architectures: the T20 is built from LUT4 and the XC6SLX25 from LUT6, so the raw LUT counts (— vs 15K) are not directly comparable.
For arithmetic, the XC6SLX25 has 38 DSP48A1 slices against 36 18×18 multipliers on the T20.
The T20 has more on-chip memory (1 Mb vs 0.9 Mb).
The T20 is designed with Efinix Efinity and the XC6SLX25 with AMD ISE Design Suite.
