Nvidia launches liquid-cooled GPUs to save water and electricity

According to NVIDIA official news, today, NVIDIA released the first data center PCIe GPU using Direct-to-Chip cooling technology.

Equinix is ​​validating the A100 80GB PCIe liquid-cooled GPU in its data center, and the GPU is now in trial phase and is expected to be officially released this summer.

According to reports, data center operators aim to eliminate the chillers used to cool the gas inside the data center because it evaporates millions of gallons of water each year. With liquid cooling, the system only needs to recycle a small amount of liquid in the closed system and can focus on the main hot spots.

Both Equinix and NVIDIA have found that data center workloads with liquid cooling can match air-cooled facilities while consuming approximately 30 percent less energy . NVIDIA estimates that the PUE for liquid-cooled data centers may reach 1.15, which is much lower than the PUE of 1.6 for air-cooled data centers. Under the same space conditions, liquid-cooled data centers can achieve double the amount of computing. This is because the A100 GPU uses only one PCIe slot, while the air-cooled A100 GPU uses two PCIe slots.

At least a dozen system makers plan to use liquid-cooled GPUs in their products later this year, including ASUS, ASRock Rack, Foxconn Industrial Internet ), GIGABYTE, H3C, Inspur, Inventec, Nettrix, QCT, Supermicro, Wiwynn ) and hyperfusion (xFusion).
