Yes, it may be a difficult problem to handle exposing hardware-specific functionality in a non-portable way, but if GPUOpen is to have any substance at all it&#x27;s obvious that they&#x27;re going to actually do some of that. This can&#x27;t just be an announcement of a batch of OpenGL vendor extensions.<p>And at the moment, it seems like GPU architectures within one company aren&#x27;t really that much more diverse than Intel&#x27;s CPU architectures over a similar time period. They&#x27;re not overhauling the ISA every year.
