What are some of the popular AI Hardware platforms available?

Do you want to explore the AI (Artificial Intelligence) on the edge and looking for a suitable embedded hardware for the same?

Recently, I got interested in AI on the edge and tried to find suitable hardware to start experimenting, instantly I got to know that thousands of people are searching for AI hardware on Google search but the information is scattered and lacking an article or blog which shares a list of useful AI hardware one can choose from. So, I decided to write one.

What are some of the popular AI Hardware platforms available? 1

Background on Computing for AI

AI algorithms takes a lot of computing power to execute and that’s the push for the need of such hardware accelerator which can solve this problem. Although, the compute power required will largely depend on the use case at hand.

More and more companies are working on building AI hardware chips because of its ability to solve complex problems once considered impossible and today, there are many options already available in the market to explore AI on the edge without spending too much money.

The list of AI hardware options listed below are a mix of complete Edge Computing board to an addon AI accelerator which could be connected to another embedded computing board over the USB.

List of popular AI Hardware:
