After the “bold” declarations of the past few hours, Intel he has put on paper what he means by “beat NVIDIA in ray tracing performance“With a video and a post on the official website of Arc, the US company has published internal tests in which the video card Arc A770current top of the range of the Alchemist generation, is compared with the GeForce RTX 3060.

The test, carried out at the resolution 1080phighlights how the Arc card is capable of outperform NVIDIA’s proposition in nearly all titles – the average sees it in front of 14%, with a maximum advantage of 56% in Fortnite. The GPU loses in F1 2022, Guardians of the Galaxy, Battlefield V and Deathloop, but Intel still has a long way to go in driver optimization, so much so that chief of technical marketing Ryan Shrout highlights how the latest driver update has improved the performance. performance with Ghostwire Tokyo up to 25%.

Another graph shows us the 1440p resolution Arc A770 video card behavior with ray tracing and XeSS enabledwith Intel’s two-way upscaling technology.

In the video, Intel explains how it approached the hardware implementation of ray tracing, inserting it inside the GPU una Ray Tracing Unit (RTU) per Xe-core, that is a computing unit dedicated exclusively to technology. The RTU can calculate 12 box intersections per cycle, one triangle intersection per cycle and has a dedicated cache for BVH data.

Each RTU includes two Ray Traversal Pipelines to quickly trace the rays along the scene geometry and manage intersections. The last piece of the puzzle is called Thread Sorting Unit and serves to implement the so-calledAsynchronous Ray Tracingthat is, to take the ray tracing calculations and group them by complexity in order to better use the Xe-cores.

At the moment unclear when we will see Arc GPUs in Italy: the debut is taking place in stages, so much so that in the United States only the Arc A380 is seen, but the A750 and A770 solutions will also arrive by the end of the year. By then, however, both NVIDIA and AMD will have presented the first next-generation solutions, which will surely put these results in a different light.
