Exploring stacked main memory architecture for 3D GPGPUs

• The tremendous number of threads on general purpose graphic processing units (GPGPUs) poses significant challenges on memory architecture design. 3D stacked main memory architecture atop GPGPU is a potential approach to provide high data communication bandwidth and low access latency to meet the requirement of GPGPUs. In this paper, we explore the performance of 3D GPGPUs with stacked main memory. The experimental results show that the 3D stacked GPGPU can provide up to 124.1% and on average 55.8% performance improvement compared to a 2D GPGPU scheme.
