Nvidia’s GTC Conference: Shifting the Focus to Energy Efficiency in AI

Nvidia’s GTC developer conference in San Jose, Calif., has been making waves in the world of AI. Dubbed as the “AI Woodstock,” the event witnessed the gathering of industry giants, including Nvidia, OpenAI, xAI, Meta, Google, and Microsoft, as well as executives from major companies such as L’Oréal, Lowe’s, Shell, and Verizon, all looking to implement AI technology.

During the conference, Nvidia CEO Jensen Huang unveiled the company’s latest graphics processing unit (GPU), the Blackwell GPU. This new chip boasts an impressive 208 billion transistors, surpassing the capabilities of its predecessor, the H100 GPUs, which had 80 billion transistors. The larger chips of the Blackwell GPU offer twice the speed for training AI models and are five times faster for generating outputs from trained models (referred to as inference). Nvidia also introduced the powerful GB200 “superchip,” incorporating two Blackwell GPUs connected to its Grace CPU, surpassing the existing Grace Hopper MGX units used in data centers.

One noteworthy aspect of the Blackwell GPU is its power profile, and Nvidia is leveraging this to its advantage in marketing the chip. In the past, powerful chips consumed more energy, with energy efficiency taking a backseat to raw performance. However, with the unveiling of the Blackwell GPU, Huang emphasized its greater processing speed and highlighted the reduced power consumption during training compared to previous models. Training ultra-large AI models using 2,000 Blackwell GPUs would require 4 megawatts of power over 90 days, compared to 8,000 older GPUs that would consume 15 megawatts for the same training period. This significant difference in power consumption addresses concerns about the monetary cost and carbon footprint associated with AI technology.

The focus on power consumption is crucial, as increasing awareness of the expenses and environmental impact of AI has made companies reluctant to fully embrace the generative AI revolution. Cloud providers, for instance, charge high fees for running GPUs, not just to account for the cost of the chips themselves, but also to cover the energy consumption and cooling requirements of data centers. Nvidia recognizes this concern and aims to alleviate it by highlighting the Blackwell’s energy efficiency. Additionally, Nvidia points out that AI experts have found ways to mimic the performance of larger, power-intensive models like GPT-4 with smaller, less energy-consuming models.

While the energy consumption of data centers for AI currently represents a small fraction of the world’s total power usage, estimates suggest it may increase rapidly in the future. Schneider Electric, for instance, approximates that AI consumes energy equal to that of Cyprus on an annual basis. According to a Microsoft expert, the deployment of Nvidia H100s alone is expected to consume as much power as the entire city of Phoenix by the end of this year.

However, the concern about AI’s energy consumption in data centers may be somewhat misplaced. Most of the data centers utilized by cloud hyperscalers, where the majority of AI processing occurs, now rely on renewable energy or low-carbon nuclear power. By contracting for large amounts of renewable power at set prices, these hyperscalers have played a vital role in encouraging renewable power companies to build wind and solar projects. This has resulted in more renewable power being available to everyone, benefiting both the cloud providers and the sustainability of energy sources. Nevertheless, the water consumption necessary for data center cooling remains an area of concern for sustainability efforts.

Although many data centers are powered sustainably, some regions may lack access to renewable energy. If AI continues to expand and AI models grow larger, the demand for renewable energy may outstrip low-carbon supplies even in the United States and Europe. This is prompting efforts, such as Microsoft’s interest in using AI to expedite the approval process for new nuclear power plants in the U.S.

AI’s energy consumption also highlights one of the many areas where natural human brains surpass the artificial ones we have created. The human brain consumes approximately 0.3 kilowatt-hours daily, primarily from caloric intake, whereas the average H100 GPU requires about 10 kilowatt-hours daily. To ensure the widespread and sustainable adoption of AI without harming the planet, artificial neural networks may need to operate with energy profiles more closely resembling their biological counterparts.

The U.K.’s Advance Research and Invention Agency (Aria), akin to the U.S. Defense Department’s DARPA, aims to address this challenge. Recently, Aria committed £42 million ($53 million) to fund projects focused on reducing the energy footprint of running AI applications by a factor of a thousand. Aria is considering radical approaches to building computer chips, including ones that rely on biological neurons for computation instead of silicon transistors. While the outcome remains uncertain, the mere existence of the Aria challenge and Nvidia’s emphasis on energy efficiency at the GTC conference signify a growing focus on reducing AI’s energy consumption and advancing sustainable practices.
