Understanding GPU caches

Previously we explored the different types of memories available for access by the GPU, but only barely touched on the topic of caches. In this article we will make up for that by taking a look at the different caches available on modern GPUs to appreciate their role in the system. Having thorough understanding of GPU cache behavior enables developers to better utilize them and thus improve the performance of their graphics or compute applications.

Just as in the previous article, our primarily focus will be on discrete GPUs and their cache hierarchy, but occasionally we will also touch on integrated implementations like those found on APUs and SoCs. Before doing that, however, it’s worth spending a bit of time on understanding the general goals of caches and the way they are usually organized into hierarchies.
