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 XC6SLX150 has about 29% more logic capacity (147K vs 114K LUT4 equivalents).
They use different logic architectures: the EP4CE115 is built from LUT4 and the XC6SLX150 from LUT6, so the raw LUT counts (114K vs 92.2K) are not directly comparable.
For arithmetic, the EP4CE115 has 266 18×18 multipliers against 180 DSP48A1 slices on the XC6SLX150.
The XC6SLX150 has more on-chip memory (4.7 Mb vs 3.8 Mb).
The EP4CE115 is designed with Altera Quartus Prime and the XC6SLX150 with AMD ISE Design Suite.
