Qualcomm Adreno 32.0.181.0 Driver Causes Snapdragon X2 Elite Local AI and Premiere...
A Reddit user's testing found that after the Snapdragon X2 Elite was upgraded to Adreno driver 32.0.181.0, local LLM inference and Premiere Pro video rendering performance dropped sharply, with declines of up to 87%. When running Qwen3 series models with llama.cpp using the OpenCL backend, Qwen3-0.6B's generation speed fell from 98.1 tokens per second to 12.8 tokens per second, Qwen3-4B from 29.5 to 9.0, and Qwen3-Coder-30B-A3B-Instruct from 26.8 to 5.9. Another user reported that the export time for a 7-minute 1080p video increased from 1 minute 40 seconds to about 10 minutes. After rolling back to driver 32.0.172.2, performance returned to normal, with the CPU and NPU not noticeably affected. Qualcomm has not yet issued a statement on the matter.
