摘要：In recent years, modern graphics processing units have been widely adopted in high performance computingareas to solve large scale computation problems. The leading GPU manufacturers Nvidia and ATI haveintroduced series of products to the market. While sharing many similar design concepts, GPUs from thesetwo manufacturers differ in several aspects on processor cores and the memory subsystem. In this paper,we choose two recently released products respectively from Nvidia and ATI and investigate the architecturaldifferences between them. Our results indicate that these two products have diverse advantages thatare reflected in their performance for different sets of applications. In addition, we also compare the energyefficiencies of these two platforms since power/energy consumption is a major concern in the highperformance computing system.
