How does neuromorphic computing compare to biological brains in energy efficiency?

Neuromorphic systems strive to match the energy efficiency of the human brain, which consumes only about 20 watts of power. This is achieved through specialized hardware that mimics biological processes, such as spiking neurons, which transmit signals only when necessary.

For instance, the Loihi chip by Intel demonstrates this efficiency by performing complex pattern recognition tasks using a fraction of the energy needed by conventional processors. In robotics, this energy-saving feature enables devices like autonomous drones to operate longer without recharging.

Despite these advancements, biological brains remain superior in adaptability and multitasking. For example, your brain can recognize a friend’s face in various lighting conditions while simultaneously recalling their name and holding a conversation—tasks that are still challenging for machines.

Why are spiking neural networks (SNNs) a game changer in neuromorphic computing?

SNNs emulate the way neurons in the human brain communicate through spikes of electrical activity, unlike traditional artificial neural networks that use continuous signals. This allows neuromorphic systems to process information in a more time-sensitive and efficient manner.

A real-world example of SNNs in action is in autonomous vehicles. SNNs allow the car to detect obstacles, predict movements, and make driving decisions almost instantaneously. This real-time processing, combined with low energy consumption, makes them an ideal choice for edge computing applications where latency is critical.
