How to Choose Hygon CPUs/DCUs? Introduction to the 3000/5000/7000 Series and the K100-AI Accelerator Card | Changfan Industrial Control

Hygon Information Product Overview: CPU + DCU Dual-Engine Drive

Hygon is one of the few Chinese chip companies possessing the R&D capabilities for both high-end general-purpose processors (CPUs) and coprocessors (DCUs). Its CPUs are compatible with the x86 instruction set—Hygon’s biggest advantage over other domestic CPU approaches: millions of x86-based system software, databases, virtualization systems, and cloud platforms can run directly, with virtually no application migration costs. The DCU (Deep Computing Unit) is a GPGPU coprocessor compatible with the CUDA (ROCm) ecosystem for AI and high-performance computing, and is one of the few accelerator cards in China supporting FP64 double-precision and full-precision computing.

These two product lines form a “dual-engine” drive: the HwHiPhi CPU serves as the foundation for general-purpose computing, while the HwHiPhi DCU acts as the engine for artificial intelligence and scientific computing. A single HwHiPhi server can simultaneously support business systems and AI workloads. Furthermore, the HwHiPhi CPU incorporates a hardware acceleration engine that supports national encryption algorithms and trusted computing mechanisms, providing a natural compliance advantage in government affairs, finance, telecommunications, and other innovative scenarios.

Detailed Information on HwHiPhi CPU 3000/5000/7000 Series

Hygon CPUs are divided into three series based on core count, memory channels, and PCIe expansion capabilities, allowing for clear positioning and selection according to specific needs:

• 3000 Series • High-performance entry-level models: Integrated with 4 to 8 cores, 2 DDR4 memory channels, 32 PCIe channels, and a maximum boost frequency of 3.3GHz. Characterized by high frequency and low core count, suitable for entry-level servers, workstations, and industrial control scenarios—a cost-effective choice for lightweight business and high-frequency sensitive applications.

• 5000 Series • Mainstream mid-range models: Integrated with 8-16 cores, 4 DDR4 memory channels, 64 PCIe channels, supporting up to 1TB of memory per chip, and supporting dual-channel configuration. Addressing the general server and edge computing needs of industries such as internet, finance, telecommunications, transportation, and energy, it is the primary model for government and enterprise information creation procurement.

• 7000 Series • Flagship Data Center Model: Integrates 16-32 cores, 8 DDR4 memory channels, 128 PCIe lanes, supports up to 2TB of memory per chip, and is optimized for power consumption in data center scenarios. Designed for scenarios with high requirements for core count, memory access performance, and scalability, such as cloud computing, big data, databases, distributed storage, and artificial intelligence.

Choose your model: Choose 3000 for high frequency and light load, 5000 for balanced general use, and 7000 for high concurrency and heavy load. Hygon CPUs have iterated to the third generation (Hygon 3) as the main product, with the fourth and fifth generations continuously evolving. It is recommended to confirm the specific generation and sales status of the selected model when purchasing.

Hygon DCU Deep Learning Series and K100-AI Accelerator Card

Hygon DCU (Deep Learning Series) is based on a GPGPU architecture, with a core specification of 60 to 64 deep computing units. It is compatible with the ROCm-like CUDA ecosystem and can be seamlessly migrated to frameworks such as PyTorch, TensorFlow, and PaddlePaddle. It is one of the lowest-cost ways to migrate AI computing power within China’s ecosystem. The K100 series is currently the mainstay:

• K100: 24.5 TFLOPS FP64 double-precision computing capability, peak power approximately 100 TFLOPS, 64GB GPU memory, 896GB/s bandwidth, and approximately 300W power consumption. It is one of the few accelerator cards in China supporting full-precision FP64 computing, designed for high-precision scenarios such as scientific computing, CAE simulation, and weather forecasting.

• K100-AI: A version suitable for AI workloads, with a peak FP16/BF16 computing capability of approximately 192 TFLOPS and INT8 of approximately 392 TOPS, 64GB VRAM, 896GB/s bandwidth, and 350W power consumption. It supports the ROCm ecosystem and domestic frameworks such as PaddlePaddle, suitable for training models with billions of parameters, memory-intensive tasks, and production inference environments.

Typical application scenarios for the K100-AI include: large model fine-tuning and inference, financial risk control modeling, biomedical molecular simulation, and intelligent manufacturing visual quality inspection. It should be objectively noted that compared to flagship international cards, there are still gaps in peak computing power and memory bandwidth. Its value lies in its large memory, FP64 full-precision support, ROCm ecosystem compatibility, and innovation and compliance capabilities. When purchasing, the actual throughput of the actual business model should be the standard, not the specifications on paper.

Hygon Platform Procurement Key Points

• Select the CPU series based on the workload: Choose the 3000 series for high-frequency, light-load scenarios; the 5000 series for general business scenarios; and the 7000 series for high-concurrency scenarios such as databases, virtualization, and AI.

• First, calculate the GPU memory usage for AI workloads: Estimate the parameter size + KV cache memory requirements for large model inference. The K100-AI’s 64GB GPU memory is suitable for memory-intensive tasks, while performance-sensitive tasks require actual measurement and evaluation.

• Confirm Production and Availability: Huawei CPUs follow a “one generation in mass production, one generation in R&D, one generation in planning” iteration cycle. When purchasing, please ensure the selected model is from the current mainstream generation to avoid purchasing discontinued models that could impact future expansion.

• Leverage x86 Compatibility Advantages: Huawei platforms can directly run mainstream operating systems and applications with low migration costs – however, compatibility testing for core business applications is still recommended.

• Information Creation Compliance Verification: For government, financial, and carrier projects, confirm procurement catalogs and localization requirements. Huawei’s built-in national encryption algorithms and trusted computing are scoring items.

• Overall Reliability: Confirm redundant power supplies, hot-swappable storage, out-of-band management, and overall system aging test reports; for DCU models, additional power supplies and thermal design for 350W-level single-card power consumption need to be considered.
