Is IBM's NorthPole AI Chip The Power-Efficient Game Changer We Need?

Attention tech enthusiasts, did you read about IBM unleashing its NorthPole AI processor?

Let's dive into the details!

IBM Corporation unveiled NorthPole, an AI chip it developed in-house, claiming to be more efficient at using power than similar CPUs in the market.

The eight years it took to create NorthPole were spent in the company's research facility in Almaden, California. The chip expands upon IBM's TrueNorth artificial intelligence processor, the result of a previous research effort. NorthPole, as claimed by IBM, is roughly 4,000 times quicker!

The newly released chip uses a 12-nanometer fabrication method to create its 22 billion transistors. IBM claims that this large number of transistors can do 2,048 eight-bit operations per clock cycle inside its 256 cores. To put it another way, the calculations are performed on numbers as little as eight bits in size.

Each of NorthPole's 256 cores has its own dedicated memory pool for storing data while it is being processed. The proximity of the chip's memory circuits and cores means that information can move quickly between them. As a result, performance is enhanced by a decrease in the processing delays normally associated with data transport.

“Architecturally, NorthPole blurs the boundary between compute and memory,” said Dharmendra Modha, IBM’s chief scientist for brain-inspired computing. “At the level of individual cores, NorthPole appears as memory-near-compute and from outside the chip, at the level of input-output, it appears as an active memory.”

What Are The Benefits Of IBM's New NorthPole AI Chip?

The memory circuits included in NorthPole's cores not only improve performance but also reduce power consumption. Transferring information from one part of a chip to another uses up resources and slows down processing. NorthPole's architecture is more efficient because it reduces the amount of time data spends traveling between memory and processing cores.

IBM determined the chip's energy usage by having it process an instance of the open-source ResNet-50 image recognition model. The model is often used to evaluate the efficacy of various AI processors. When compared to graphics cards and CPUs based on 12- and 14-nanometer nodes, IBM claims that NorthPole's power efficiency for running ResNet-50 is 25 times higher.

The NorthPole chip is manufactured at a 12-nanometer node, which is several generations behind the most modern chip manufacturing method, which operates at a 3-nanometer node. The processor, however, can be updated to make use of more recent production methods. Based on their analysis, IBM experts believe that NorthPole can improve energy efficiency by a factor of 25 compared to competing devices using "current designs."

The quantity of heat generated by a CPU is proportional to its power consumption. IBM claims that NorthPole's maximum temperature is capped by the chip's energy efficiency, meaning that it can function with minimal external cooling. Therefore, it may be used in systems with limited room for cooling equipment, such as driverless vehicles. #Innovation
