Cisco unveils AI-focused chip to link massive data centers

/in /tarafından

Cisco Systems has introduced a new networking chip, the P200, designed to connect large-scale AI data centers across vast distances. The technology, which will power a new generation of high-capacity routers, has already attracted major clients including Microsoft Azure and Alibaba Cloud, the company announced Wednesday.

The P200 aims to solve a growing challenge in artificial intelligence — connecting geographically distant data centers so they can operate as one massive computing system. “AI training jobs are now so large, they require multiple data centers working together — even a thousand miles apart,” said Martin Lund, Cisco’s executive vice president of common hardware.

The chip consolidates what previously required 92 separate components into one, allowing routers to use 65% less power. Cisco said the innovation helps AI firms manage rising energy demands as data centers spread to regions such as Texas and Louisiana, where electricity is more abundant.

The P200 will compete directly with Broadcom’s networking chips, offering faster data synchronization and more efficient buffering technology, a crucial feature for ensuring AI workloads remain stable across distributed systems.

Industry leaders including Microsoft’s Dave Maltz praised the move, saying the chip provides “faster networks with more buffering to absorb bursts of data,” critical for scaling AI operations. Cisco did not disclose investment costs or revenue expectations but said the chip represents a major leap in AI infrastructure efficiency.

Samsung and SK Hynix to Supply Chips for OpenAI’s $500 Billion Stargate Project

/in /tarafından

Samsung Electronics and SK Hynix, South Korea’s top semiconductor manufacturers, have signed letters of intent to supply memory chips for OpenAI’s massive Stargate project, marking a major step in Seoul’s growing role in global artificial intelligence infrastructure.

As part of the deal, OpenAI will collaborate with both companies to build two new AI data centers in South Korea, branded as “Korean-style Stargate,” aligning with President Lee Jae Myung’s goal of turning the country into an AI innovation hub in Asia. The decision leverages South Korea’s strong industrial base and its status as the world’s second-largest ChatGPT subscription market after the United States.

The agreements were announced on Wednesday following a high-profile meeting in Seoul between OpenAI CEO Sam Altman, President Lee Jae Myung, and the chairmen of Samsung Electronics and SK Hynix.

The Stargate project, unveiled by U.S. President Donald Trump in January, aims to invest $500 billion into developing next-generation AI infrastructure with global partners such as SoftBank, Oracle, and now the South Korean chip giants. The initiative seeks to secure the computing capacity needed to sustain AI’s rapid growth and maintain U.S. leadership in the field.

South Korea’s presidential adviser Kim Yong-beom revealed that OpenAI plans to order 900,000 semiconductor wafers by 2029 and establish joint ventures with Samsung and SK Hynix to operate two 20-megawatt-capacity data centers domestically.

“The significant part of the Stargate project would be impossible without memory chips from the two companies,” said Kim.

He added that South Korea may also participate in financing the project.

Altman, in his remarks, emphasized the strategic importance of Korea:

“Korea has an industrial base like nowhere else in the world that is critical for the development of AI. We’re very excited to build Stargate Korea with Samsung and Hynix to support the sovereign AI needs of the country.”

Together, Samsung and SK Hynix control about 70% of the global DRAM market and nearly 80% of the HBM (High Bandwidth Memory) market. HBM technology, introduced in 2013, stacks chips vertically to save space, boost performance, and reduce power consumption, making it vital for AI data processing.

Analysts estimate that 900,000 wafers of advanced DRAM could be worth more than 100 trillion won ($70 billion), though prices may fluctuate depending on market conditions.

In addition to the memory supply deals:

  • Samsung SDS, an IT services affiliate, signed a partnership with OpenAI to develop and operate AI data centers under the Stargate framework.

  • Samsung Heavy Industries and Samsung C&T will collaborate on floating offshore data centers, designed to reduce cooling costs and carbon emissions.

Meanwhile, Google has also been in talks with several South Korean companies to explore potential AI collaborations. In June, SK Group announced a 7 trillion won investment, including $4 billion from Amazon Web Services, to build another major data center in the country.

Despite optimism about AI’s transformative potential, some investors remain cautious, citing the risk of a tech infrastructure bubble as companies rush to build large-scale data facilities.

The Stargate project, delayed earlier by prolonged negotiations and site selection, is now poised to gain new momentum through this South Korea partnership, reinforcing the nation’s position at the heart of the global AI supply chain.

Microsoft expands Wisconsin AI data center investment to $7 billion

/in /tarafından

Microsoft announced plans to build a second major artificial intelligence data center in Wisconsin, raising its total investment in the state to more than $7 billion. The new $4 billion facility will join a $3.3 billion data center already under construction in Mount Pleasant, Racine County, first unveiled last year.

The initial data center is expected to open in 2026 and employ about 500 people, while the addition of the second will expand staffing to around 800. Microsoft says the combined site will eventually host the world’s most powerful AI supercomputer, linking together hundreds of thousands of Nvidia chips.

The development comes on land once earmarked for Foxconn’s highly publicized $10 billion factory, a project dramatically scaled back after initial political fanfare during Donald Trump’s presidency. When President Joe Biden attended Microsoft’s first announcement last year, he highlighted Foxconn’s retreat as a cautionary tale while framing Microsoft’s plan as a sign of renewed investment.

Microsoft said it will pre-pay for electrical infrastructure to avoid burdening local customers with higher power bills and will use Wisconsin’s cold climate for energy-efficient cooling. Annual water consumption will be capped at roughly the level of an average restaurant. To offset its energy use, the company will also build solar power elsewhere in Wisconsin, though Microsoft President Brad Smith noted new fossil fuel generation—specifically liquefied natural gas—will still be part of the mix.

While the 800 permanent jobs fall short of the thousands promised by Foxconn, Smith emphasized the importance of ongoing skilled labor positions, including pipefitters and electricians, needed for both construction and long-term maintenance.
