Frequently Asked Questions (FAQs)

FAQs About GPU Repurposing Factories in China

What are Chinese factories doing with Nvidia gaming GPUs

Chinese factories are disassembling Nvidia gaming GPUs, such as the GeForce RTX 4090, to convert them into AI accelerators for use in data centers. This process involves desoldering the GPU and memory components and reassembling them on custom-designed circuit boards.

Why are Chinese factories repurposing Nvidia GPUs

The repurposing is a response to US sanctions that restrict the export of high-end AI accelerators like Nvidia’s A100 and H100 GPUs to China. With these sanctions in place, Chinese companies are finding alternative ways to meet their AI computing needs by converting available gaming GPUs.

How many GPUs are being repurposed

The scale of repurposing is significant. For example, one Chinese factory reported disassembling over 4,000 Nvidia GeForce graphics cards in December alone, with the activity increasing fourfold in a short period.

Who are the main customers of these repurposed AI accelerators

The primary customers are public enterprises and small AI labs that did not stockpile enough commercial AI accelerators before the US sanctions took effect. These entities are relying on these repurposed GPUs to meet their AI computing requirements.

Are Chinese companies developing their own GPUs to replace Nvidia’s

Yes, Chinese companies like Biren Technology and Moore Threads are developing domestic GPUs to compete with Nvidia. However, these domestic GPUs still face challenges in matching the performance and ecosystem of Nvidia’s products, particularly in areas like the CUDA software ecosystem.
