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: 370K and 382K LUT4 equivalents.

They use different logic architectures: the 5SGXB5 is built from ALMs and the XC6VHX380T from LUT6, so the raw LUT counts (185K vs 239K) are not directly comparable.

For arithmetic, the XC6VHX380T has 864 DSP48E1 slices against 399 variable-precision DSP blocks on the 5SGXB5.

The 5SGXB5 has more on-chip memory (41 Mb vs 27 Mb).

Both have transceivers: 66 at up to 14.1 Gb/s on the 5SGXB5 and 72 at up to 11.18 Gb/s on the XC6VHX380T.

The 5SGXB5 is designed with Altera Quartus Prime and the XC6VHX380T with AMD ISE Design Suite.
