Ubuntu 24.04 outperforms Windows 11 in rendering and local AI performance benchmarks

Ubuntu 24.04 demonstrates a 24.1% performance advantage over Windows 11 across a comprehensive workload index of 60 speed checks. Testing conducted on RTX 5090 and RTX 5080 hardware reveals that Ubuntu consistently delivers faster render times in Blender 4.5.14 and higher token generation rates for local AI models, including Qwen, DeepSeek, and Llama. In Blender synthetic and classroom scenes, Ubuntu consistently reduces frame render times compared to Windows 11. For local AI, Ubuntu provides higher token-per-second throughput and lower latency for both initial and full response generation. Furthermore, Ubuntu exhibits superior memory management, offering significantly more available OS RAM headroom during intensive rendering and AI tasks. The testing also indicates that Ubuntu provides more efficient file-based I/O performance, with higher read speeds in fio benchmarks compared to Windows DiskSpd. These results suggest that for professional rendering and local AI inference, the Linux-based environment provides a more optimized software stack for current NVIDIA hardware.

Ubuntu 24.04 achieves a 24.1% faster overall performance across 60 distinct workload checks compared to Windows 11. Blender 4.5.14 render times are consistently lower on Ubuntu 24.04 across RTX 5090 and RTX 5080 configurations.

Local AI inference tasks show higher token generation rates and lower latency on Ubuntu compared to Windows 11. Ubuntu 24.04 provides significantly more available OS RAM headroom during heavy rendering and AI processing workloads.

File-based I/O benchmarks demonstrate higher read speeds on Ubuntu using fio compared to Windows DiskSpd. The testing confirms that Ubuntu 24.04 is fully capable of headless operation and provides robust fan control on NVIDIA hardware.
