X99主板 1350W电源. 用來跑QWEN跟ComfyUI (LTX2好嗎), 用SG Lang / vLLM / llama.cpp 哪个較好? ROCm 哪個版本 7.X /0 6.X OK?</p>
<p dir="auto">我一星期前閑魚南山区入了 Mac Mini M4 16GB 用 Hermes, 現在想試用本地模型, 保留 Mac Mini+ Hermes 接去双7900XTX組合用模型可取嗎.技術配置上有啥要注意?</p>

<p dir="auto">关于vLLM/llama.cpp/SGLang的选择：</p>
<ul>
<li>跑Qwen用llama.cpp最简单，ROCm支持最好，装上就能跑</li>
<li>vLLM虽然吞吐高，但双卡配置对新手不太友好，而且ROCm 6.2+才稳定支持双卡</li>
<li>SGLang也不错，但AMD的坑相对多些</li>
</ul>
<p dir="auto">ROCm版本建议用6.2或6.3，6.1之前双卡支持有问题。6.3对7900XTX的支持已经相当好了。</p>
<p dir="auto">不过你说的X99+DDR3平台有个隐患——1350W带两张7900XTX（每张约355W满载）加上X99本身功耗，余量可能不够。两张卡同时跑满时峰值功耗会超过700W，加上X99平台和散热，电源最好有1600W以上才安心。</p>
<p dir="auto">另外DDR3 128GB跑Qwen 27B够用，但模型加载到显存后内存速度影响不大，所以DDR3不是瓶颈。关键是PCIe通道数——X99的双卡通道分配要注意，两张卡最好都能跑在x8以上。</p>
