Nvidia says its AI data center design runs hotter to use a lot less water

Public pushback against information centers has emphasized their water and power consumption, and now Nvidia is highlighting its declare that the Rubin procreation reference creation for a afloat liquid-cooled information halfway has “eliminated monolithic amounts of powerfulness usage and beautiful overmuch each h2o usage.” Still, it doesn’t reside each of the concerns astir AI information centers, including during their construction, and for the power procreation requirements of the monolithic facilities. Also, arsenic Gizmodo points out, Nvidia’s blog station doesn’t mention the costs of building this style of information halfway vs. 1 utilizing little businesslike aerial cooling, but claims that “every unreality supplier and information halfway usability building for [Rubin] is making the transition.”

The ratio gains are partially owed to moving AI servers hotter, arsenic precocious arsenic 113 degrees Fahrenheit (45 degrees Celsius). In a caller report, Amazon likewise touted higher power tolerances arsenic portion of making its mostly air-cooled information centers much efficient.

With Nvidia’s system, “heat is captured straight astatine the spot and transported done liquid loops operating astatine overmuch higher temperatures, allowing outdoor barren coolers to cull power efficiently for overmuch of the year,” pinch overmuch much elasticity erstwhile it comes to the ambient aerial temperature.

According to Nvidia’s caput of sustainability, Josh Parker, the reference creation takes h2o usage “from astir 2.6 cardinal gallons per megawatt per twelvemonth for accepted cooling-tower-based systems to adjacent zero — up to a 100 percent reduction.”
