A cognitive computer is a computer that hardwires artificial intelligence and machine learning algorithms into an integrated circuit that closely reproduces the behavior of the human brain.[1] It generally adopts a neuromorphic engineering approach. Synonyms include neuromorphic chip and cognitive chip.[2][3]
In 2023, IBM's proof-of-concept NorthPole chip achieved remarkable performance in
In 2013, IBM developed
IBM TrueNorth chip
TrueNorth was a

Memory, computation, and communication are handled in each of the 4096 neurosynaptic cores, TrueNorth circumvents the
The neurons are emulated using a Linear-Leak Integrate-and-Fire (LLIF) model, a simplification of the leaky
According to IBM, it does not have a clock,[15] operates on unary numbers, and computes by counting to a maximum of 19 bits.[6][16] The cores are event-driven by using both synchronous and asynchronous logic, and are interconnected through an asynchronous packet-switched mesh network on chip (NOC).[16]
IBM developed a new network to program and use TrueNorth. It included a simulator, a new programming language, an integrated programming environment, and libraries.[15] This lack of backward compatibility with any previous technology (e.g., C++ compilers) poses serious vendor lock-in risks and other adverse consequences that may prevent it from commercialization in the future.[15][failed verification]
Research
In 2018, a cluster of TrueNorth network-linked to a master computer was used in stereo vision research that attempted to extract the depth of rapidly moving objects in a scene.[17]
IBM NorthPole chip
In 2023, IBM released its NorthPole chip, which is a
Intel Loihi chip
Pohoiki Springs
Pohoiki Springs is a system that incorporates Intel's self-learning neuromorphic chip, named Loihi, introduceed in 2017, perhaps named after the Hawaiian
The first iteration of the chip was made using Intel's 14 nm fabrication process and houses 128 clusters of 1,024
In October 2019, researchers from
In March 2020, Intel and Cornell University published a research paper to demonstrate the ability of Intel's Loihi to recognize different hazardous materials, which could eventually aid to "diagnose diseases, detect weapons and explosives, find narcotics, and spot signs of smoke and carbon monoxide".[26]
Hala Point
Intel's Loihi 2, named Pohoiki, was released in September 2021 with 64 cores.[27] It boasts faster speeds, higher-bandwidth inter-chip communications for enhanced scalability, increased capacity per chip, a more compact size due to process scaling, and improved programmability.[28]
Intel claimed in 2024 that Hala Point was the world’s largest neuromorphic system. It uses Loihi 2 chips. It is claimed to offer 10x more neuron capacity and up to 12x higher performance.
Hala Point provides up to 20 quadrillion operations per second, (20 petaops), with efficiency exceeding 15 trillion (8-bit) operations S-1 W-1 on conventional deep neural networks. This rivals levels achieved by GPU/CPU architectures. Hala Point packages 1,152 Loihi 2 processors produced on Intel 3 process node in a six-rack-unit chassis. The system supports up to 1.15 billion neurons and 128 billion synapses distributed over 140,544 neuromorphic processing cores, consuming 2,600 watts of power. It includes over 2,300 embedded x86 processors for ancillary computations.
Hala Point integrates processing, memory and communication channels in a massively parallelized fabric, providing 16 PB S-1 of memory bandwidth, 3.5 PB S-1 of inter-core communication bandwidth, and 5 TB S-1 of inter-chip bandwidth.
The system can process its 1.15 billion neurons 20 times faster than a human brain. Its neuron capacity is roughly equivalent to that of an owl brain or the cortex of a capuchin monkey.
Loihi-based systems can perform inference and optimization using 100 times less energy at speeds as much as 50 times faster than CPU/GPU architectures.

In 2021, The New York Times released Steve Lohr's article "What Ever Happened to IBM’s Watson?".[32] He wrote about some costly failures of IBM Watson. One of them, a cancer-related project called the Oncology Expert Advisor,[33] was abandoned in 2016 as a costly failure. During the collaboration, Watson could not use patient data. Watson struggled to decipher doctors’ notes and patient histories.
