How do cuda cores help with gaming?

Solution

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...

The Kepler to Maxwell architecture jump saw nearly a 40% efficiency gain in CUDA core processing ability, illustrating the difficulty of linearly drawing comparisons without proper benchmarks.

CUDA Cores are parallel processors, just like your CPU might be a dual- or quad-core device, nVidia GPUs host several hundred or thousand cores. The cores are responsible for processing all the data that is fed into and out of the GPU, performing game graphics calculations that are resolved visually to the end-user. An example of something a CUDA core might do would include rendering scenery in-game, drawing character models, or resolving complex lighting and shading within an environment.



So the short answer to your question: Yes it gives more fps added in other factors also ofc like speed of the gpu chip and memory speed.

You can look to Tom's history for the answer. C+P this question into that search box up there. Tom's archive is monstrous. You can look to it for so many different answers and questions, tutorials, articles and so much more.

http://www.tomshardware.com/answers/id-2187119/cuda-cores-games.html gives a short and sweet answer.

Same here http://www.tomshardware.com/forum/363933-33-what-cuda . There's more to a GFX card than FPS and GAMING!!! Soundworks 2017? LOVES CUDA cores. AMD cards? Not so much. It's called GPU acceleration.
