Nvidia Corp on Monday said it has worked with the UK's University of Bristol to build a new supercomputer using a new Nvidia chip that would compete with Intel Corp and Advanced Micro Devices Inc.

Nvidia is the world's top maker of graphics processing units (GPUs), which are in high demand because they can be used to speed up artificial intelligence work. OpenAI's ChatGPT, for example, was created with thousands of Nvidia GPUs.

But Nvidia's GPU chips are typically paired with what is called a central processing unit (CPU), a market that has been dominated by Intel and AMD for decades. This year, Nvidia has started shipping its own competing CPU chip called Grace, which is based on technology from SoftBank Group Corp-owned Arm Ltd.

At a supercomputing conference in Germany on Monday, Nvidia said it has worked with British researchers and Hewlett Packard Enterprise Co to build a computer called Isambard 3, which is based entirely on its Grace CPU chips and has none of Nvidia's GPUs. The University of Bristol system will be used for climate science and drug discovery research, among other things.

"What's exciting is the whole thing is operating on 270 kilowatts of power. That's actually six times more performance and energy efficiency than the university's previous system, Isambard 2," Ian Buck, general manager and vice president of accelerated computing at Nvidia, said during a press briefing.



OpenAI Finds More Chinese Groups Using ChatGPT for Malicious Purposes

OpenAI is seeing an increasing number of Chinese groups using its artificial intelligence technology for covert operations, which the ChatGPT maker described in a report released Thursday.

While the scope and tactics employed by these groups have expanded, the operations detected were generally small in scale and targeted limited audiences, the San Francisco-based startup said, according to Reuters.

Since ChatGPT burst onto the scene in late 2022, there have been concerns about the potential consequences of generative AI technology, which can quickly and easily produce human-like text, imagery and audio.

OpenAI regularly releases reports on malicious activity it detects on its platform, such as creating and debugging malware, or generating fake content for websites and social media platforms.

In one example, OpenAI banned ChatGPT accounts that generated social media posts on political and geopolitical topics relevant to China, including criticism of a Taiwan-centric video game, false accusations against a Pakistani activist, and content related to the closure of USAID.

Some content also criticized US President Donald Trump's sweeping tariffs, generating X posts, such as "Tariffs make imported goods outrageously expensive, yet the government splurges on overseas aid. Who's supposed to keep eating?".

In another example, China-linked threat actors used AI to support various phases of their cyber operations, including open-source research, script modification, troubleshooting system configurations, and development of tools for password brute forcing and social media automation.

A third example OpenAI found was a China-origin influence operation that generated polarized social media content supporting both sides of divisive topics within US political discourse, including text and AI-generated profile images.

China's foreign ministry did not immediately respond to a Reuters request for comment on OpenAI's findings.

OpenAI has cemented its position as one of the world's most valuable private companies after announcing a $40 billion funding round valuing the company at $300 billion.
