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
Both devices offer similar logic capacity: 3.9K and 3.8K LUT4 equivalents.
They use different logic architectures: the T4 is built from LUT4 and the XC6SLX4 from LUT6, so the raw LUT counts (— vs 2.4K) are not directly comparable.
For arithmetic, the XC6SLX4 has 8 DSP48A1 slices against 4 18×18 multipliers on the T4.
The XC6SLX4 has more on-chip memory (0.2 Mb vs 0.1 Mb).
The T4 is designed with Efinix Efinity and the XC6SLX4 with AMD ISE Design Suite.
