NPU chips (neural network processors) and CPU chips (central processing units) are two different types of chips, and their differences are as follows:
< br >
NPU chips are specifically designed to accelerate neural network computing, while CPU chips are designed to perform general-purpose computing.
< br >
Architectures differ: NPU chips typically have a vector processor architecture that enables them to handle multiple computation tasks simultaneously, while CPU chips typically have a scalar processor architecture that can only handle one computation task at a time.

Different energy consumption: Due to the special architecture of the NPU chip, it is often able to provide higher performance when performing neural network computing tasks, while being able to use energy more efficiently, reduce computing time, and reduce energy consumption.

NPU chips are typically used in scenarios that require high-performance neural network computing, such as artificial intelligence, machine learning, and computer vision. The CPU chip is suitable for general purpose computing scenarios, such as running software programs, browsing the web and processing files.

In general, NPU chips and CPU chips are fundamentally different, and they are usually designed and optimized for different application scenarios. NPU chips have gradually become the standard for all kinds of smart devices, such as smartphones, cameras and even self-driving cars, and it will help people get more benefits from them in many areas.

People usually call the mobile phone processor CPU, in fact, this is not correct, the CPU is only a small part of the many processing units of the processor.

In fact, the more professional is the SOC,SOC is the abbreviation of System on Chip, called the chip-level system, there are also called system-on-chip, meaning that it is a product, is an integrated circuit with a special goal, which contains the complete system and all the content of embedded software. Generally speaking, it is a system-level chip.

The mobile phone processor is not only a CPU, it integrates many functions including the GPU for processing images, and the smart chip NPU also integrates signal baseband.

CPU is the brain of the whole system operation, is the central processing unit, simply put, is a digital calculator, processing data, all the software you see needs to calculate, such as playing sokoban games have to use the CPU calculation, calculate the result value.

Gpus are image processors that specialize in processing images. In order to solve the difficulties encountered by the CPU in large-scale computing GPU came into being, it must be called by the CPU control to work.

NPU is a neural network processing unit that simulates human neurons and synapses in circuits. Implement artificial intelligence computing. To produce a new kind of computing chip that can react in a similar way to human intelligence.
