LuxMark v3.1 Benchmark
LuxMark is a OpenCL cross-platform benchmark tool that has been around since 2009. It was intended as a promotional tool for LuxCoreRender and remains a popular benchmark for those interested in OpenCL performance. LuxMark is now based on LuxCore, the LuxRender v2.x API available under Apache Licence 2.0 and freely usable in open source and commercial applications.
BasemarkGPU was introduced back in 2018 as a free multi-platform, multi-API 3D graphics benchmark. The benchmark was written in C++ and developed using their own in-house game engine called Rocksolid. The desktop version runs an AAA quality game-like workload as each scene has tens of thousands of individual draw calls per frame. We ran this benchmark and charted the results for the DirectX 12 and Vulkan APIs.
