Radeon RX 6800 XT performs half as good compared to RTX 3080 in Vulkan Ray Tracing tests

Radeon RX 6800 XT performs half as good compared to RTX 3080 in Vulkan Ray Tracing tests

You've been able to read our many Radeon RX 6800 reviews, where we noted that DirectX Raytracing performance does lack quite a bit compared to NVIDIA"s the latest generation. However, VULKAN just started supporting raytracing as well.

The Khronos Group released an extension for the use of Ray Tracing with Vulkan. Vulkan is an open source API that traces way back towards AMD's own Mantle API if you can remember it. Somewhat a solution or alternative to OpenGL. However, the Ray Tracing extension for Vulkan relies heavily on the VK_NV_ray_tracing extension that Nvidia worked hard to support RT on Vulkan. Some early testing has been performed, and that paints a rather red picture for AMD's Radeon 6800 XT. Testing was performed in Quake II RTX, which uses a full path tracer to render for its non-complicated 1997 geometry.

Performance sucks on both of them.

The RX 6000 series' lack of RT performance is a bit of a mystery. It really seems like AMD was aiming at barely beating/matching the first generation Nvidia RT, despite the huge criticism back in the day about Turing RT being next to useless in practice. AMD specifically didn't include ray tracing in the 5000 series because they didn't feel like they were ready for it. Didn't AMD seriously anticipate Nvidia overhauling the ray tracing performance in the Ampere architecture? It's puzzling.

This is AMD's first attempt at RT. No surprises here for me . I wonder how it looks compared to the first generation RT from NV. Nevertheless RT sucks on both of them. Without cheating with DLSS even NV 30 series sucks. IMO RT is great but for the future :)

I'm going to skip this generation out. Not going to pay scalping prices for unpar RT performance. That was my requirement to upgrade the GPU.

Wait for 4080Ti or 7800XTX next year for more performance at half of current costs.
