Intel seems pretty confident about its upcoming Arc A770 and A750 graphics cards, especially in terms of ray tracing as it claims that they can match NVIDIA's RTX 30-series GPUs, or even surpass them, in ray tracing performance.
Speaking to PC Gamer, Intel's Ryan Shrout and Tom Petersen shared that they expect A770 and A750's performance will be able to compete with NVIDIA's RTX 360 in games that run DirectX 12 adding that their ray tracing units (RTU) are "particularly well suited for delivering real ray tracing performance."
"And you'll see that when you do ray tracing on comparisons with an [RTX] 3060 versus A750 or A770, we should fare very, very well," Peterson said. "Yeah, we're definitely competitive or better than NVIDIA with ray tracing hardware."
Peterson explained that two key factors lead to the company's confidence that Intel's RTU will beat its competitors in terms of ray tracing acceleration. The first one is a bounding volume hierarchy (BVH) cache within the GPU which is used to accelerate BVH traversal, and another factor is a thread sorting unit which plays an important role in the processing hierarchy of how ray tracing functions on an Arc GPU.
According to Peterson, while the two technologies help A770 and A750 to reach great ray tracing performance, Intel also had to make sure that those technologies required as little developer engagement as possible in order to make them work.
"All of our technology pretty much has to work with low dev rel (developer relations) or dev tech engagement," he said. "And so things like our cache structure and our hierarchy, you know, our thread sorting unit, which are the two techs that we're going to talk about in [the upcoming video explainer], they work without any dev rel or dev tech work."
