An Indian cloud provider has adopted Nvidia GPU servers cooled using synthetic diamonds.

Akash Systems this week announced it has delivered the world's first diamond-cooled GPUs to NxtGen AI, an Indian cloud provider.

NxtGen has received Nvidia H200 GPU servers equipped with Akash's proprietary diamond cooling technology.

Full details on the number of servers and where they have been deployed haven't been shared.

California-based Akash says its cooling tech is projected to reduce data center energy consumption and increase FLOPs/Watt by up to 15 percent per server in facilities running at temperatures up to 50°C (122°F), compared to the common standard of 24-29°C (75-85°F).

"Diamond cooling solves the two hardest problems in the AI infrastructure race – energy and capital efficiency – by improving Power Use Effectiveness and rapidly densifying token output. Diamond cooling raises the bar for performance and speed of data center deployments by significantly reducing power consumption and densifying server capacity," said Dr. Felix Ejeckam, co-founder & CEO of Akash Systems. "In a world where a one to two percent increase in compute is meaningful, a 15 percent increase in GPU compute is truly game-changing. We're proud to partner with NxtGen on the first-ever deployment of diamond-cooled servers in the world."

Diamond is a very efficient thermally conductive material, enabling heat to be removed 5x faster than the current industry standard, copper. Akash uses synthetic diamond materials on the chips to remove heat more efficiently than copper. The company claims to be able to reduce GPU hotspot temperatures by 10°C (50°F).

"At NxtGen, our mission is to build the most performant cloud backbone to power India's AI innovators. By integrating Akash's diamond cooling into our infrastructure, we are delivering a more competitive solution for our customers, while driving cost-efficiency for our bottom line," said A.S. Rajgopal, CEO of NxtGen. "Diamond cooling is going to become part of every AI Factory's development strategy – with this world first deployment, NxtGen just took a major step ahead."

NxtGen offers a number of IT services, including cloud, CDN, colocation, and disaster recovery. The company reportedly currently operates data centers across Ahmedabad, Bangalore, Faridabad, and Mumbai

Reports last year said the two companies had signed a $27 million deal for the supply of the diamond-cooled GPUs.

Akash is backed by venture capital investors Khosla Ventures and Founders Fund. The firm has secured more than $20 million across six funding rounds.

The company originally developed its gallium nitride-on-diamond (GaN-on-diamond) technology for use in orbit for satellite radios. As well as the Nvidia H200, Akash offers several server variants equipped with AMD GPUs and plans to release additional aftermarket diamond cooling solutions for other Nvidia GPU systems, including the Blackwell series.
