Beijing, China – Facing stringent US export controls designed to impede its technological progress, particularly in military applications, China has reportedly achieved a significant breakthrough in chip development. According to a detailed report published by Chinese publisher DeepTech, researchers have developed a novel optical chip that they claim demonstrates processing speeds substantially exceeding those of commercially available advanced graphics processing units (GPUs).
The development comes as US restrictions have effectively blocked Chinese entities from purchasing high-end GPUs like Nvidia’s RTX 4090 and the anticipated RTX 5090, key components for advanced AI training and high-performance computing.
A Leap in Optical Computing Power
The new optical chip, the technical specifics of which were outlined in the DeepTech report, is reported to achieve a theoretical peak computing power of 2,560 TOPS (tera-operations per second). This performance is cited at an optical frequency of 50GHz. Researchers claim this capability allows for a dramatic increase in ‘optical computility’ – the processing power derived from light – without requiring a corresponding increase in the chip’s physical size.
To put this in perspective, the report offers comparisons to Nvidia’s powerful GPUs, which are widely used in data centers and for AI development globally. The RTX 4090, a high-end consumer and prosumer card, is noted to have reached 1,321 TOPS. While Nvidia’s next-generation RTX 5090 is anticipated to peak at 3,352 TOPS, the new Chinese optical chip’s claimed 2,560 TOPS places it theoretically between these two powerful conventional electronic chips in raw processing operations per second.
Developers associated with the project stated that this achievement represents a potential 100-fold or greater increase in optical computing efficiency compared to previous attempts. They position this advancement as paving a crucial “new path for future optical computers,” which could fundamentally alter the landscape of high-speed computation.
Integrated System Architecture
The technological achievement is embodied in an integrated system referred to as Meteor-1. The DeepTech report details that this system utilizes a fully self-developed architecture. This architecture is composed of several key components, highlighting China’s focus on indigenous innovation in critical technology areas.
The core components of the Meteor-1 system include a light source chip, which generates the optical signals used for computation; an optical interaction chip, which facilitates the complex interactions and processing of light signals; an optical computing chip, the central processing unit leveraging light; and a modulation matrix driver board, which controls and directs the optical signals through the system.
This comprehensive, self-reliant architecture underscores an effort to build a complete domestic ecosystem for advanced computing, reducing reliance on foreign technology chains, particularly those impacted by US export controls.
Implications for AI and Data Centers
The researchers behind the optical chip development anticipate that this innovation will provide significant hardware acceleration, specifically targeting the escalating computational demands faced by artificial intelligence development and large-scale data centers. The relentless growth of AI models and the increasing volume of data necessitate ever more powerful and efficient processing capabilities.
Conventional electronic chips face physical limitations as they approach atomic scales, leading to challenges with heat dissipation and energy consumption. Optical computing, which uses photons instead of electrons, theoretically offers the potential for higher speeds, lower power consumption, and greater bandwidth.
The development of a functional, high-performance optical chip capable of exceeding the processing power of leading conventional GPUs could therefore offer a viable alternative or complement to existing silicon-based computing infrastructure. This is particularly critical for China’s ambitions in AI research, development, and deployment, areas heavily reliant on massive computational resources.
The Global Tech Race Intensifies
This reported breakthrough occurs within the broader context of an intensifying global competition for technological supremacy, particularly between the United States and China. The US export controls, initially implemented to curb China’s access to advanced semiconductors that could enhance its military capabilities, appear to be inadvertently accelerating China’s pursuit of alternative computing paradigms.
While the practical performance and scalability of the new optical chip in real-world applications remain to be fully demonstrated and verified by independent sources, the theoretical capabilities outlined in the DeepTech report signal a notable step forward in optical computing. It underscores China’s determination to overcome external technological constraints through focused domestic research and development, potentially reshaping the future trajectory of high-performance computing and artificial intelligence globally.
