Fragment Shader Interlock Performance on an AMD Radeon RX 6900 XT

This is another update of the articles "Fragment Shader Interlock Performance (α Compositing)" and "Fragment Shader Interlock Performance on the Steam Deck", where I previously had a look at the performance of a GPU feature called fragment shader interlock for alpha composition. In the first article, I was not able to test the performance on AMD GPUs, as the fragment shader …

Fragment Shader Interlock Performance on the Steam Deck

This is an update of the article "Fragment Shader Interlock Performance (α Compositing)", where I previously had a look at the performance of a GPU feature called fragment shader interlock for alpha composition. In this article, I said: I would love to also test whether fragment shader interlock also comes out as the performance winner on AMD hardware, but unfortunately AMD does not …

Fragment Shader Interlock Performance (α Compositing)

Over the last decades, how GPUs can be used radically evolved. In the olden days™, GPUs had specialized units for vertex and fragment processing. Due to multiple reasons, one being that different applications may utilize these different types of units to different degrees, a shift to unified units happened that would perform both vertex and fragment processing. For a more in-depth view on the …
