- Chinese photonic chips reportedly outperform conventional GPUs in narrow, specialized generative AI tasks
- ACCEL combines photonic and analog electronic components to achieve high computational throughput
- LightGen uses over two million photonic neurons for all-optical generative AI processing
Chinese research institutions have described new photonic AI chips that allegedly outperform conventional GPUs by a very large margin under specific conditions.
The institutions and researchers claim these chips show dramatic upgrades in speed and energy efficiency when executing narrowly defined generative workloads.
They reported China’s light-based AI chips offer 100x faster speed than Nvidia GPUs at some tasks, particularly in areas such as image synthesis, video generation, and vision-related inference.
Claims of extreme speed from optical computing research
These claims are framed around laboratory evaluations rather than commercial deployment scenarios, but the performance gap is closely tied to fundamental architectural differences.
Nvidia GPUs, including widely used accelerators such as the A100, rely on electronic circuits where electrons move through transistors to execute programmable instructions.
This approach allows flexibility across many workloads but results in high power consumption, significant heat output, and dependence on advanced manufacturing nodes.
The Chinese photonic chips instead rely on light-based signal processing, where photons replace…
