Agent-BONCHIP ATTEND PCIe M.2 Gen5 connector, which fully supports the above signals and protocols, is widely used.AIoT terminal, intelligent medical instrument, industrial control board and edge serverWait.

Efficient synergy between AI accelerator and M.2 connector

AI accelerators (such as GPUs, TPUs, FPGAs, ASICs, etc.) are processors optimized for deep learning and neural network computing. These modules have extremely high requirements for bandwidth, data throughput, and low latency.

✅Advantages of M.2 connectors:

Multi-channel PCIe high bandwidth: Ensure fast data flow for large-scale model training and data inference.
Small design for easy integration: Suitable for space-limited platforms such as laptop, embedded AI box, vehicle-mounted equipment, etc.
Strong protocol compatibility: Support various AI acceleration modules to adapt to different scene requirements
Modular expansionSupport hot plug and flexible expansion, easy system upgrade and customized deployment

The key to SSD storage performance upgrade-M. 2 Interface

in the AI systemSSDNeed to undertake the task of high-speed storage and recall of large-scale training data, especially inReal-time generative AI applicationsThe system has high requirements for storage latency, bandwidth, and concurrent processing capabilities.

🔋M.2 interface to enhance the role of SSD:

Significant increase in read and write bandwidthNVMe SSD with M.2 interface, read and write speed up to several GB/s
Ultra-low access latencyEspecially critical for real-time AI inference scenarios (e. g. image recognition, speech processing)
Enhanced edge computing capabilities: Some M.2 SSDs integrate AI coprocessors to enable local data preprocessing and reduce the pressure on the main system.

The underlying dynamics driving the development of generative AI

Generative AI models represented by GAN and Transformer require a lot of computing power and massive storage resources, and the application of M.2 connectors enables the flexible integration of these resources, driving the rapid landing of generative AI in multiple industries.

📈Changes brought about by the integrated M.2 solution:

Increased training efficiency: AI accelerator NVMe SSD works together to greatly shorten the model training cycle.
Decreased inference latency: Smoother response for real-time scenes such as image generation and content creation
System scalability is stronger: Supports multi-module cascading to adapt to the growing trend of model size
Promote innovation in AI researchReduced hardware bottlenecks allow researchers to focus on algorithm optimization and model expansion.

M.2 Future trends in connectivity technology

M.2 technology is still evolving rapidly and is expected to further advance AI hardware in the future:
