Blender 5.1 Delivers Some Nice Gains For CPU Rendering Performance On Linux

With this week's release of [2]Blender 5.1 I have begun benchmarking it on different CPUs and GPUs. In this article is an initial look at the positive impact Blender 5.1 is having on CPU-based rendering performance on Linux.

Blender 5.1 release notes mention the CPU rendering performance on Windows is improved by 5~20%. There wasn't any Linux mention specifically but with Blender 5.1 I am finding up to a few percent faster render speeds on Linux compared to Blender 5.0. The Cycles engine in Blender 5.1 is said to improve GPU rendering performance by 5~10%, but in my tests with the NVIDIA CUDA and OptiX back-ends I didn't see that overall and for a few scenes was slower with Blender 5.1 compared to Blender 5.0.

Most of my testing thus far of Blender 5.1 was done on the new [4]System76 Thelio Mira desktop with the AMD Ryzen 9 9950X Zen 5 processor and NVIDIA GeForce RTX 5080 graphics card while running Pop!_OS 24.04 LTS.

With Blender 5.1 the CPU rendering performance was up to a few percent faster across the different scenes tested. With complex scenes like Barbershop this can equate to some measurable time savings if doing a lot of work with Blender. These CPU results align with what I've seen out of Blender 5.1 on various other CPUs tested thus far.
