AMD Promises Higher Performance Radeons With RDNA 4 In The Not So Distant Future

The commentary didn't come right out and say that "RDNA 4 will be [x]" or "have [x]", but rather, as statements about AMD's David Wang and Rick Bergman's ideas about how computer graphics will evolve. For example, Wang acknowledged that NVIDIA has placed a great emphasis on the use of AI. Wang says that AMD doesn't have the same strategy, and that AMD doesn't believe GPU AI accelerators are being used well in the consumer market.

Wang says that, rather than image processing, he'd like to see AI acceleration on graphics cards instead used to make games "more advanced and fun," and he gives the example of "the movement and behavior of enemy characters and NPCs," an area of game programming often referred to as "AI" despite its distant relation to the study of neural networks.
4Gamer points out that AMD's RDNA 3 includes in hardware a "Multi-Draw Indirect Accelerator" used for multi-draw indirect operations. This is a method of dispatching multiple instanced draw commands in such a way that they can be issued entirely on the GPU, saving quite a bit of overhead. Apparently, RDNA 3 can do this 2.3x faster than RDNA 2, and we might see further improvements along these lines in RDNA 4.
Likely the most interesting part of the interview, at least with respect to RDNA 4, is the statement toward the end where AMD's Rick Bergman says that the company "promises to evolve to RDNA 4 with even higher performance in the near future." It shouldn't be a surprise to anyone that the company expects its next-generation GPUs to be even faster than its extant products, but "in the near future" sounds like the company could be moving to RDNA 4 earlier than expected.
