B.1 GPU Compute Capability Tables

As we discussed in Chapters 6-10, maximizing the kernel performance on a particular GPU requires knowledge of the resource limitations in the GPU hardware. Therefore, the main hardware resource provisions in each GPU are typically exposed to applications in a standardized system called compute capability. The general specifications and features of a compute device depend on its compute capability. For CUDA, the compute capability starts at Compute 1.0, and at the time of this writing the latest version is Compute 3.5. Each higher level of compute capability indicates a newer generation ...
