Intel has announced a new version of Loihi, a self-learning neuromorphic chip (Greek: meaning nerve + form) that aspires to mimic the human brain, and is used in neural networks. Loihi 2 will be built using the Intel 4 process node, that’s not 4nm, but rather Intel’s unique process metric. It was previously called 7nm, although this doesn’t match any measurement on the die. This is the first silicon announced for this node, which is due to hit PC processors in 2023. Loihi contains a million artificial neurons and is destined for “neuro-inspired” research projects that aim to build a machine that ‘thinks’ rather than computes. A Loihi chip may never come to a rig on your desk, but the results of these research projects could be profound –CL.
