In the interview, Su called ray tracing an important technology, and she revealed AMD is working on it as well, both from a hardware and software standpoint:
“I think ray tracing is an important technology, and it’s something we’re working on as well, both from a hardware and software standpoint,” Su said. “The most important thing, and that’s why we talk so much about the development community, is technology for technology’s sake is okay, but technology done together with partners who are fully engaged is really important.”Su said parts of the ray tracing ecosystem aren't ready yet, which means the consumer doesn't see a lot of benefit today. She provided no indication on when we can expect the first ray tracing GPUs from AMD, this will likely take a lot of time.
