How to Choose the Right FPGA: Xilinx vs Altera vs Lattice

Why the right FPGA choice matters

Choosing an FPGA is one of the highest-impact decisions in any new hardware design. The three major suppliers — Xilinx (AMD), Altera (Intel PSG) and Lattice Semiconductor — cover very different points on the cost / performance / power spectrum. As an IC chip distributor working with all three brands every day, ICseekers puts together this practical selection guide.

Xilinx / AMD: performance leader

Xilinx dominates where raw logic density, DSP capability and transceiver bandwidth are required. The Virtex UltraScale+ (XCVU9P, XCVU13P) family targets 5G radio, radar processing and AI acceleration; Kintex UltraScale (XCKU085, XCKU115) delivers similar fabric at lower cost for medical imaging and broadcast. For cost-sensitive designs, Artix-7 and Spartan-7 remain popular. Xilinx devices are usually the choice when a single FPGA must absorb an entire signal chain.

Altera / Intel PSG: balanced and feature-rich

Intel’s PSG business (formerly Altera) is strong in transceiver-dense designs and hardened SoC solutions. The Stratix 10 / Agilex families compete head-to-head with Virtex; Cyclone V / Arria 10 SoC FPGAs combine ARM hard processor systems with fabric, simplifying designs that need both a CPU and custom logic. For legacy designs, EPM7256 and EP4CE series are still widely sourced — ICseekers keeps long-term supply of these discontinued favourites.

Lattice: low power wins

Lattice’s iCE40, MachXO and ECP5 families own the low-power, small-package niche: battery instruments, sensor fusion, and system management. If your design draws milliamps, Lattice is often the only realistic FPGA.

Sourcing tips from our team

• Check availability before locking the pin-out — lead times vary from 8 to 52 weeks.
• For legacy parts (XC5VLX50T, EP4SGX180, LC4064V), verify date codes and traceability with your supplier.
• Buy one extra lot for engineering builds; late-stage shortages are common on new families.
