Densest GPU system architecture: NVIDIA GRID provides the highest number of concurrent, interactive data streams by using multi-GPU servers and sophisticated NVIDIA VGX GPU-sharing technology.
In some cases the technologies sit side by side in devices - Apple's iPhone 5, for example, features a PowerVR GPU based on Imagination's architecture, and Apple's A6 CPU which is based on ARM's work.
Hyper-Q -- This enables multiple CPU cores to simultaneously use the CUDA architecture cores on a single Kepler GPU. This dramatically increases GPU utilization, slashing CPU idle times and advancing programmability.
