Figure 1. Power delivery and power efficiency has become the largest concern in large scale computing systems. The industry has witnessed a dramatic increase in power consumed by processors with the advent of ASICs and GPUs processing complex AI functions. Rack power has also subsequently increased with AI capability being utilized in large scale learning and inferencing application deployments. In most cases, power delivery is now the limiting factor in computing performance as new CPUs look to consume ever increasing currents. Power delivery entails not just the distribution of power but also the efficiency, size, cost and thermal performance
The increasing complexity and variety of compute workloads demand immense processing capabilities. Whether used in a cloud data center or on-premise, a new breed of processors is able to increase throughput and reduce latency. However, processor advances are pushing power delivery boundaries.
