This month I have been doing a lot of Panther Lake benchmarking under Linux with the Core Ultra X7 358H. One of the areas of much interest has been the Arc B390 Xe3 graphics that have been working nicely out-of-the-box with the Intel open-source driver stack on Linux although there still are some gaps to fill against Windows. Those Intel Arc B390 Linux benchmarks so far have been focused on OpenGL and Vulkan graphics, but what about OpenCL and GPU compute with the open-source Intel Compute Runtime? Today's article is looking at the performance of the Xe3 Panther Lake graphics on the newest Compute Runtime release compared to prior Intel graphics generations and the AMD Ryzen AI competition.
