Raspberry Pi's latest AI HAT+ 2 promises to bring serious AI horsepower to the beloved single-board computer. But does the performance justify the cost? That's the question I've been wrestling with after putting this add-on through its paces.
Hailo NPU: A Real Step Up?
The star of the show is undoubtedly the Hailo NPU (Neural Processing Unit). Tom's Hardware reports that this chip offers a significant boost in AI processing capabilities compared to previous Raspberry Pi AI solutions. The claim is that it's now capable of running larger language models (LLMs) and handling complex image inference tasks directly on the device. This opens up exciting possibilities for edge computing applications, robotics, and local AI processing, where sending data to the cloud isn't feasible or desirable.
I tested the AI HAT+ 2 with a few different models. The performance jump is noticeable. Image recognition tasks that choked older Raspberry Pi setups now run smoothly. LLMs, while not blazing fast, are actually usable for simple tasks. The real benefit here is offloading the AI workload from the Raspberry Pi's CPU, freeing it up for other tasks and improving overall system responsiveness. But I'm not entirely sold that the performance increase justifies the premium price.
The Price is the Problem
And that brings us to the elephant in the room: the price. The exact cost hasn't been officially announced by Raspberry Pi, but sources suggest it will be significantly more expensive than previous AI HATs. This puts it in competition with other dedicated AI development boards. For hobbyists and makers on a budget, this price point could be a deal-breaker. The value proposition is questionable. Are you better off buying a more powerful Raspberry Pi, or even a different single-board computer altogether?
The build quality seems solid enough, but frankly, at this price, I expect nothing less. The software integration is also relatively smooth, which is a plus. However, the high cost makes it a tough sell unless you absolutely need that extra AI processing power in a Raspberry Pi form factor.
The Raspberry Pi AI HAT+ 2 is a powerful piece of kit that brings real AI capabilities to the Raspberry Pi ecosystem. However, the high price tag makes it difficult to recommend for the average user. Unless you have a specific need for on-device AI processing and are willing to pay a premium, you might be better off exploring other options. We'll need to see the final pricing and availability to truly assess its value.
