Intel’s New AI Chip
Intel’s Loihi is different because its crude analogs of neurons are burned into hardware, and its design differs fundamentally from the computer chips the world runs on today. In conventional chips, data shuttles back and forth between a processor and separate memory. Loihi’s “neurons” and the adjustable connections between them function as both processor and memory, saving time and energy required to shuffle data around. The connections—analogous to synapses—between neurons can adjust to patterns in their activity over time, mimicking a learning mechanism seen in real brains. Tests of this ability have included showing the chip videos of people performing movements such as bicep curls, and challenging it to recognize the same motion in fresh video clips.
