Unexpected Vulkan Speedup in LLM Benchmarking
Read Full Article: Unexpected Vulkan Speedup in LLM Benchmarking
Benchmarking local language models (LLMs) on a 3080 10GB GPU revealed that while CUDA generally outperforms Vulkan in token generation rates, certain models show unexpected speed improvements with Vulkan. Notably, the GLM4 9B Q6 model experienced a 2.2x speedup in prompt processing and a 1.7x speedup in token generation using Vulkan. Similarly, the Ministral3 14B 2512 Q4 model saw a significant 4.4x speedup in prompt processing and a 1.6x speedup in token generation. These findings suggest that Vulkan may offer performance benefits for specific models, particularly when partially offloaded to the GPU. This matters as it highlights potential optimizations for developers working with LLMs on different hardware configurations.
