As technology continues its rapid advancement, one piece of hardware has emerged as a highly sought-after commodity: the graphics processing unit (GPU). In recent years, GPUs have gained popularity and become indispensable components in various devices, from high-end AI systems to everyday smartphones and gaming consoles.
Originally designed to generate and display complex 3D scenes and objects, GPUs have evolved to handle a wide range of tasks, including video stream decompression. What sets GPUs apart from central processing units (CPUs) is their parallel processing capability. While CPUs consist of a small number of cores that process tasks sequentially, GPUs have thousands of smaller cores that work simultaneously, resulting in faster and more efficient processing for tasks that require numerous simple operations.
The utility of GPUs goes beyond graphics rendering. They have found a significant role in the field of artificial intelligence (AI), particularly in machine learning techniques like deep neural networks. GPUs excel in performing matrix multiplication, a crucial mathematical operation in AI, due to their exceptional parallel processing capabilities. As a result, they significantly expedite AI-related computations.
Continual advancements in chip manufacturing, with companies like TSMC leading the way, have contributed to the increasing power of GPUs. Smaller transistors allow for more transistors to be packed into the same physical space, enhancing their overall performance. However, it’s important to note that traditional GPUs, while beneficial for AI tasks, are not the most optimal solution.
Enter data center GPUs and specialized AI accelerators. Designed to support machine learning tasks more efficiently, these accelerators offer faster processing speeds and increased memory capacity. Companies like AMD and NVIDIA have adapted their traditional GPUs to better handle AI workloads, while others like Google and Tenstorrent have developed purpose-built accelerators from scratch. These accelerators boast more memory, crucial for training large AI models, and can be combined to form supercomputers or produced as single, large-scale accelerators.
Meanwhile, CPUs have also made progress in supporting AI tasks, particularly inference tasks, but for AI model training, GPU-like accelerators are still crucial.
As the technology landscape evolves, the potential for even more specialized accelerators for specific machine learning algorithms is a possibility. However, the challenges lie in the substantial engineering resources required and the potential for these algorithms to become outdated.
In conclusion, GPUs have expanded beyond their initial purpose and become integral to the world of AI and computing. With their parallel processing capabilities and increasing power, they are driving advancements across various industries, shaping the future of technology.
