With some of the clpeak benchmarks the Intel Compute Runtime performance did come in short of the NVIDIA driver.

VkResample benchmark with settings of Upscale: 2x, Precision: Single. RTX 3080 was the fastest.

The Intel Arc Graphics were also performing well with VkResample for Vulkan compute, but I'll leave more of the Vulkan compute benchmarks for a separate article while also incorporating the Radeon graphics cards with RADV.

Overall this was the best showing we've seen yet out of the Intel Arc Graphics OpenCL/compute performance under Linux with their open-source software coming together quite well. While the Arc Graphics A770 at the top-end can't come close to matching the best possible solutions from NVIDIA or AMD, when it comes to maximizing your value and/or being concerned about having a fully open-source driver stack, the Intel Arc Graphics are increasingly proving quite capable for Linux users. Plus with Ubuntu 23.10 and Fedora Workstation 39 around, the out-of-the-box Intel Arc Graphics experience for OpenGL and Vulkan is much nicer now in H2'2023 than it was in H1. There's also other excitement on the horizon such as the forthcoming Xe kernel driver.

Those wishing to see this round of OpenCL NVIDIA vs. Intel compute benchmarks in full can find all the data v ia this result file. Stay tuned for the 1080p Linux gaming/graphics comparison next week.
