Highlighted values are higher. Logic is compared in LUT4 equivalents; see how FPGA vendors count logic.

Key differences

Both devices offer similar logic capacity: 364K and 356K LUT4 equivalents.

They use different logic architectures: the 10AX048 is built from ALMs and the XC7K355T from LUT6, so the raw LUT counts (182K vs 223K) are not directly comparable.

For arithmetic, the XC7K355T has 1,440 DSP slices against 1,368 variable-precision DSP blocks on the 10AX048.

The 10AX048 has more on-chip memory (28.1 Mb vs 25.1 Mb).

Both have transceivers: 36 at up to 17.4 Gb/s on the 10AX048 and 24 at up to 12.5 Gb/s on the XC7K355T.

The 10AX048 is designed with Altera Quartus Prime and the XC7K355T with AMD Vivado.
