During yesterday's Radeon RX 6800 & 6900 reveal event, AMD didn't exactly reveal a lot of details regarding its hardware support for ray-tracing.

However, one performance measurement for AMD's Ray Accelerator cores slipped through in the slides shared with the press, based on Microsoft's DXR SDK Procedural Geometry sample application. From this test alone, NVIDIA's Ampere-based GeForce RTX 3000 Series graphics cards appear to be significantly faster than the competition in ray-tracing, which we were kind of expecting given that NVIDIA had the headstart of an entire generation in this area. Of course, more tests will be needed in order to properly ascertain the performance differences between the latest AMD and NVIDIA graphics cards.
