CUDA Cores -- Just a small part of the larger whole when it comes to an nVidia GPU. A "CUDA Core" is nVidia's equivalent to AMD's "Stream Processors." NVidia's proprietary parallel computing programming model, CUDA (Compute Unified Device Architecture), is a specialized programming language that can leverage the GPU in specific ways to perform tasks with greater performance. Each GPU can contain hundreds to thousands of CUDA cores. Architecture changes in a fashion that makes cross-generation comparisons often non-linear, but generally speaking (within a generation), more CUDA cores will equate more raw compute power from the GPU. The Kepler to Maxwell architecture jump saw nearly a 40% efficiency gain in CUDA...
