Qwen2部署在4090上速度多快

关于“qwen2部署在4090上速度多快”的问题,以下是相关内容的整理和回答:

  1. qwen2的性能

    • Qwen 2模型的参数范围从0.5到720亿,具有强大的语言生成能力。
    • Qwen 2 72B模型的性能超过Llama3 70B模型,显示出其在处理复杂任务时的优势。
  2. 在4090上的运行速度

    • 在4090显卡上运行Qwen2 14B的量化版本需要21.62 GB的显存,推荐速度为63.71 tokens per second。
    • 4090显卡的显存为24GB,但在处理大模型(如70B)时可能会不足,尤其是在没有NVLink的情况下,多个显卡的性能不如单个显卡。
  3. 对比其他显卡

    • A100显卡更适合运行大规模模型(如70B),而4090显卡在处理大模型时可能会受到显存的限制。
    • 4090显卡在没有NVLink的情况下,多个显卡的性能不如单个显卡,可能需要更多的显卡来满足需求。
  4. 总结

    • Qwen2在4090上的速度表现为63.71 tokens per second,适合中等规模的模型,但在处理更大规模的模型时可能会遇到显存不足的问题。

综上所述,qwen2部署在4090上的速度为63.71 tokens per second,适合处理中等规模的任务,但在面对更大规模的模型时,可能需要考虑显存的限制。

Qwen-2-7B和GLM-4-9B:“大模型届的比亚迪秦L”_qwen2 glm4-CSDN博客

文章浏览阅读2.4k次,点赞19次,收藏13次。实测下,7B到14B其性能是飞跃性的,实际体感上,Qwen-1.5-14B已经是非常好用的模型了。我们第一时间部署了GLM-4-9B到本地服务器,将之前的项目替换LLM引擎,在使用上GLM-4-9B表现较好,不如Qwen-1.5-32B,但也可以支撑起整个应用流程,大概到了Qwen-1.5-14B的水平。感觉Qwen-2-7B和GLM-4-9B的接连发布,有点比亚迪秦L内卷能耗的感觉,入行一周年,深感这一年间大模型行业发展迅速。Qwen-2-7B在......
