On Monday, Nvidia unveiled the Blackwell B200 tensor core chip—the company's most powerful single-chip GPU, with 208 billion transistors—which Nvidia claims can reduce AI inference operating costs (such as running ChatGPT ) and energy consumption by up to 25 times compared to the H100 . The company also unveiled the GB200, a "superchip" that combines two B200 chips and a Grace CPU for even more performance.

The news came as part of Nvidia's annual GTC conference, which is taking place this week at the San Jose Convention Center. Nvidia CEO Jensen Huang delivered the keynote Monday afternoon. "We need bigger GPUs," Huang said during his keynote. The Blackwell platform will allow the training of trillion-parameter AI models that will make today's generative AI models look rudimentary in comparison, he said. For reference, OpenAI's GPT-3, launched in 2020, included 175 billion parameters. Parameter count is a rough indicator of AI model complexity.

Nvidia named the Blackwell architecture after David Harold Blackwell , a mathematician who specialized in game theory and statistics and was the first Black scholar inducted into the National Academy of Sciences. The platform introduces six technologies for accelerated computing, including a second-generation Transformer Engine, fifth-generation NVLink, RAS Engine, secure AI capabilities, and a decompression engine for accelerated database queries.

On Wednesday, authorities arrested former Google software engineer Linwei Ding in Newark, California, on charges of stealing AI trade secrets from the company. The US Department of Justice alleges that Ding, a Chinese national, committed the theft while secretly working with two China-based companies.

According to the indictment , Ding, who was hired by Google in 2019 and had access to confidential information about the company's data centers, began uploading hundreds of files into a personal Google Cloud account two years ago.

The trade secrets Ding allegedly copied contained "detailed information about the architecture and functionality of GPU and TPU chips and systems, the software that allows the chips to communicate and execute tasks, and the software that orchestrates thousands of chips into a supercomputer capable of executing at the cutting edge of machine learning and AI technology," according to the indictment.
