IC: Turning to gaming solutions, because there is a lot of interest in how Intel is going to attack the gaming space: what we’ve seen today is a compute GPU based on chiplets. Moving from a monolithic graphics chip to a chiplet design is a tough paradigm to solve, so does working on chiplets help solve the ‘multi-GPU’ issue on graphics? Is the future of graphics still consigned to single GPU, or should we expect multiple GPU scaling easier to manage?
RK: That’s a great question. As you know, solving the multi-GPU problem is tough – it has been part of my pursuits for almost 15 years. I’m excited, especially now, because multiple things are happening. As you know, the software aspect of multi-GPU was the biggest problem, and getting compatibility across applications was tough. So things like chiplets, and the amount of bandwidth now going on between GPUs, and other things makes it a more exciting task for the industry to take a second attempt. I think due to these continual advances, as well as new paradigms, we are getting closer to solving this problem. Chiplets and advancement of interconnect will be a great boost on the hardware side. The other big problem is software architecture. With many interesting cloud-based GPU efforts, I am optimistic that we will solve the software problems as well.
