Definitions and functional focus
AI Chip:
This a chip specifically designed for processing artificial intelligence tasks. Its primary function is to efficiently run deep learning algorithms, such as training and inference of neural networks. For instance in image recognition tasks, an AI chip can quickly process pixel information in images, recognizing target objects through numerous convolution and pooling operations. Common application scenarios include AI in data centers, smart voice assistants, and environmental perception in autonomous vehicles. The focus is on accelerating the execution of AI algorithms to provide high-performance AI computing capabilities.
SoC Chip (System on a Chip):
This is a chip that integrates multiple functional components, aiming to provide a complete system solution. It usually includes a processorlike CPU, GPU), storage units, various interfaces (like USB, Ethernet, SPI, etc.), and other peripheral devices (like timers, interrupt controllers, etc An SoC chip can control and coordinate the operation of multiple devices. For example, in a smartphone, the SoC chip manages various components such as the display camera, and communication module, enabling them to work together to provide functions like making calls, browsing the internet, and taking photos.
Internal architecture
AI Chip:
architectural design focuses on how to efficiently handle matrix operations and tensor operations in AI tasks. It generally has a large number of dedicated computing units, such as Tensor Processing (TPU) or specialized Neural Network Processors (NPU). These computing units can process large amounts of data in parallel, accelerating the inference and training of learning models. For instance, some AI chips use a systolic array architecture, where data flows between computing units in an orderly manner, like blood flowing through veins significantly improving computational efficiency.
SoC Chip:
The architecture is relatively complex as it needs to integrate various types of functional modules. It typically centers around one or more-purpose processors (like a CPU), surrounded by various dedicated hardware accelerators (like a GPU for graphics processing, a DSP for digital signal processing), a storage subsystemincluding high-speed caches, memory controllers, etc.), and various interface controllers. These modules communicate with each other through high-speed buses (like AMBA buses) to data can be quickly transmitted between different components.

Energy Consumption Characteristics
AI Chip:
When executing AI, the energy consumption mainly focuses on a large number of parallel computing units. Since it is specifically designed for AI tasks, it can achieve high energy efficiency when running learning algorithms, provided that the algorithm and chip architecture match well. For example, during image recognition tasks, AI chips can quickly complete calculations and enter a low state. However, if used for non-AI tasks, the energy consumption may be high or the efficiency low due to the architectural characteristics.
SoC Chip:
The energy consumption situation is more complex, as it includes multiple functional modules, and the energy consumption of different modules varies in different working states. For instance, when the in the SoC chip performs complex calculations or the GPU renders graphics, the energy consumption will significantly increase. During standby or execution of simple tasks, power management technology reduce the energy consumption of some modules. The design of SoC chips needs to consider the energy consumption of each functional module to achieve overall low-power design.
