For decades, semiconductor advancements followed Moore’s Law, which predicted that the number of transistors on a chip would double approximately every two years, leading to significant improvements in digital technology. This trend explained the dramatic enhancement in the performance and affordability of devices like smartphones. However, as transistors have become extremely small, continuing this predictable progress has become challenging due to economic and physical limits.
Bill Dally, chief scientist at Nvidia, acknowledges that Moore’s Law is no longer driving the rapid advancements it once did. Nvidia, known for its powerful graphics processing units (GPUs) crucial for AI, is innovating in other ways to improve performance. Despite the rising costs and diminishing returns of smaller transistors, Nvidia’s Hopper architecture, launched in 2022, achieved better performance through alternative innovations.
Researchers at Nvidia, Google DeepMind, and other institutions are exploring new methods to enhance AI hardware. One technique involves sparsity, which reduces computational load by rounding small numbers to zero without affecting the accuracy of neural networks. Dally remains optimistic about continued progress in hardware innovation, which will support the growing power of AI and impact various fields such as healthcare, finance, and e-commerce.
