Nvidia tests: DPUs can cut power needed by servers


The chip maker says tests of its BlueField-2 data-processing units (DPU) in servers results in significant power savings over servers that don’t use the specialized chips to offload tasks from the CPUs.

The DPUs, or SmartNICs, take on certain workloads—packet routing, encryption, real-time data analysis—leaving the CPU free to process data. But Nvidia says they can also reduce power consumption.

The four tests involved running similar workloads on servers with and without DPUs, and Nvidia concluded that even with the additional power draw by the DPUs, overall power consumption by the servers dropped.
