Choosing Your Edge AI Engine: Hailo-8 vs. Hailo-8L
Deploying artificial intelligence at the edge—where power, space, and thermal budgets are tightly constrained—requires hardware that punches well above its weight class. Enter Hailo, a pioneer in specialized deep learning processors. Known for mimicking the dataflow architecture of the human brain, Hailo’s accelerators bypass the traditional bottlenecks of power-hungry GPUs.
Within their lineup, two prominent choices frequently land on the developer’s workbench: the high-performance Hailo-8 and its streamlined sibling, the Hailo-8L. While they share a foundational architecture and software ecosystem, they target distinct performance tiers, price points, and workloads.
1. Core Specifications at a Glance
The most direct way to understand the difference between the two processors comes down to compute capacity and physical interface options:
| Feature | Hailo-8 | Hailo-8L |
| :— | :— | :— |
| INT8 Performance | Up to 26 TOPS | Up to 13 TOPS |
| Compute Architecture | Full-scale neural core | Exactly half the compute resources of the Hailo-8 |
| Form Factors | M.2 (Key M, Key B+M, Key A+E) | M.2 (Key B+M, Key A+E) |
| PCIe Interface | Up to PCIe Gen3 x4 (Key M) or x2 | PCIe Gen3 x2 |
| Typical Power Consumption | ~2.5W – 8.25W (depending on workload) | Ultra-low power (~1.5W typical) |
