While general purpose computing on GPUs continues to enjoy higher computing performance with every new generation. The high power consumption of GPUs is an increasingly important concern. To create power-efficient GPUs, it is important to thoroughly study its power consumption. The power consumption of GPUs varies significantly with workloads. Therefore, in this work we study GPU power consumption at a detailed level and its correlation with well-known workload characteristics such as IPC. The low IPC kernels are further explored for the possible bottlenecks.
