I don’t know too much about their technology and the website isn’t giving away too much detail. It doesn’t look like they are using spiking networks, so no event-based neuromorphic tech, but perhaps good old linear algebra/ANN ML. They’re using analog computation which is attractive power-wise, but in the past has always suffered from variability due to device mismatch. Unless they have some really revolutionary process or algorithm that magically makes the downsides of mismatch disappear, they’ll have a hard time going beyond what has been tried in analog computing before (and which had its heyday in the 70s).

Looks like a different approach. Intel's chip is based on digital circuits. They try an analog approach.
