شريحة تعمل بالضوء تعزز الذكاء الاصطناعي بكفاءة 100 مرة

University of Florida Researchers unveiled a light-powered chip designed to push AI to new heights. The purpose-built microchip relies on photons rather than electrons to provide performance comparable to today’s most advanced options, while using only a fraction of the energy. Here’s how the light-powered chip could help to push AI technologies further than ever before.

لماذا يحتاج الذكاء الاصطناعي إلى حلول عتادية جديدة

As AI systems become critical to many of today’s most advanced technologies, cracks continue to appear in the current strategy.  Today’s approach relies on ever-evolving algorithms to increase performance. In the past, this strategy was effective because AI engineers could develop more efficient and purpose-built algorithms to enhance performance without hitting hardware roadblocks.

متطلبات الحوسبة

However, today’s AI ecosystem looks much different, as the hardware can’t keep up with growing computational demands. Even the smallest technological limitations, such as the time it takes for electrons to travel across a chip, have proven to be limiting factors in driving AI performance ahead.

استهلاك الطاقة

This computational overhead also comes with added energy requirements. The more chips used to power an AI system, the more energy it uses. Today’s most powerful AI system requires massive data centers that can consume as much energy as entire cities.

قيود التوسع

These requirements have put a cap on the scalability of the current AI system. In order to surpass these restrictions, AI engineers need to reduce the computational requirements of AI tasks, as chip speed enhancements have stalled. As part of this strategy, scientists have begun to look at ways to reduce the computational demand of convolution operations.

لماذا عملية الالتفاف تستهلك طاقةً كبيرةً في الذكاء الاصطناعي

Convolution operations are a crucial task that AI systems undertake. This term refers to how neural networks can identify patterns. Notably, convolution can span multiple sources, locating patterns through text, image, and video files. This process is one of the core components of modern AI, and it’s the most power-hungry aspect of modern systems. Notably, in some AI systems, up to ~90% of total power consumption is due to convolution.
