Q & A

What is the current status of the Chinese AI chip development?

China is making significant progress in AI chip development, with companies like Huawei developing competitive AI GPUs, such as the Ascend 910B, which performs close to NVIDIA’s A100 GPU.

Why are yields a major issue in Huawei's AI chip manufacturing?

Huawei is facing low yields, with 4 out of 5 chips being defective. This is a significant problem because low yields indicate a higher percentage of defective chips, making mass production inefficient.

What challenges does SMIC face in manufacturing Huawei’s AI chips?

SMIC is struggling to manufacture 7nm chips without EUV machines. They are relying on DUV machines with a complex and error-prone multi-patterning technique, which leads to yield issues.

What design strategy might Huawei use to improve yields in their AI chips?

Huawei may redesign their chips using more relaxed layout design rules, known as DRC rules, or utilize different design libraries. This approach has worked in their Kirin chip redesign and could help improve yields.

What impact does Ampere Computing have on the AI chip market?

Ampere Computing, a US-based startup, focuses on developing energy-efficient ARM-based chips for the cloud market. Their AmpereOne chip, with 256 cores, claims significant energy efficiency and performance benefits over competitors like AMD and Intel.

Who are Ampere Computing's primary competitors in the cloud chip market?

Ampere’s main competitors are Intel and AMD, which offer their Sierra Forest, Clearwater Forest, and Bergamo CPUs. Ampere differentiates itself with better performance per watt.

Why is power efficiency so important in data centers?

Power efficiency is critical due to the growing energy consumption of AI workloads in data centers. It is estimated that by 2030, data centers could use 10% of the total US electricity output and more than double their CO2 emissions.

What is the role of multi-core designs in Ampere’s chips?

Ampere’s multi-core design aims to achieve higher performance by using a large number of smaller cores. Their AmpereOne chip, for example, features 256 cores, optimized for cloud-native tasks.

What is the trend in the chip industry regarding vertical integration?

There is a growing trend for companies to build their own chips, integrating vertically. Major players like Amazon, Microsoft, Google, and NVIDIA are all developing custom chips to meet specific performance and power efficiency needs.

How could Ampere remain competitive in the future?

Ampere’s success depends on its ability to deliver chips that are either significantly better in performance or much cheaper than competitors, especially as many of its original customers are now building their own chips.
