Hailo-8 vs. Hailo-8L: Choosing the Right Edge AI Accelerator
The edge AI landscape has shifted dramatically away from power-hungry GPUs toward dedicated, highly optimized neural processing units (NPUs). Among the most prominent players in this space is Hailo, whose high-performance processors have become standard choices for smart cameras, industrial automation, robotics, and developer boards like the Raspberry Pi 5.
Within Hailo’s flagship product line, two chips stand out for mainstream edge deployments: the Hailo-8 and its streamlined sibling, the Hailo-8L. While they share a common architectural DNA and software ecosystem, they target different performance thresholds, power budgets, and project costs.
Core Specifications at a Glance
| Feature / Metric | Hailo-8L | Hailo-8 |
| :— | :— | :— |
| Peak INT8 Performance | 13 TOPS | 26 TOPS |
| Compute Architecture | Full structural design (scaled) | Full structural design |
| Typical Power Consumption| ~1.5W – 2.5W (Workload dependent) | ~2.5W – 5W+ (Workload dependent) |
| Form Factors Available | M.2 (A+E, B+M keys) | M.2 (A+E, B+M, M keys) |
| PCIe Interface Lanes | Typically PCIe Gen3 x2 | Up to PCIe Gen3 x4 (M-key variants) |
| Target Use Case | Cost-sensitive, moderate vision tasks | High-throughput vision, multi-stream processing |
The Underlying Difference: Scale, Not Speed
At their core, the Hailo-8 and Hailo-8L are built on the same proprietary dataflow architecture, meaning they process neural networks using dataflow rather than traditional register-heavy von Neumann computing.
The primary physical difference is straightforward: the Hailo-8L features roughly half the compute elements (MACs and structural resources) of the full Hailo-8.
