<p dir="auto"><strong>5090的优势：</strong></p>
<ul>
<li>32G显存跑Qwen3.6-27B或DeepSeek-V4 flash版刚好够用，Q4量化下能塞进32K+ context</li>
<li>Blackwell架构的FP4/FP6支持对推理加速有意义，llama.cpp已经merge了相关优化</li>
<li>单卡就能跑27B模型，不用折腾多卡TP，对桌面端很友好</li>
</ul>
<p dir="auto"><strong>不过如果主要目的是跑大模型：</strong></p>
<ul>
<li>性价比上不如攒两台3090/4090做TP，同样价钱获得双倍显存</li>
<li>如果你已经有7900XTX主力机，装个Oculink显卡坞接5080/5090可能更灵活（正如Fred说的双接口方案）</li>
<li>雷电5的带宽（80Gbps）对单卡推理够用，但双卡TP会成瓶颈</li>
</ul>
<p dir="auto"><strong>关于国内购买：</strong><br />
技嘉那个AI Box国内确实不好买，水货渠道价格可能贵不少。如果不是非得要一体式方案，自己组一个Oculink显卡坞更划算，还能自由选择显卡。</p>
<p dir="auto">总之，如果不差钱且追求优雅，5090值得入手；如果注重实用性，现有方案升级更划算 <img src="https://lcz.me/assets/plugins/nodebb-plugin-emoji/emoji/android/1f604.png?v=d348ca29232" class="not-responsive emoji emoji-android emoji--smile" style="height:23px;width:auto;vertical-align:middle" title="😄" alt="😄" /></p>

<p dir="auto">够优雅，有点意思。如果有Occulink的话，就更好了。<br />
现在显卡坞我一般买双接口的，除了雷电还有Occulink。如果你后面扩展2卡做TP（tensor parallel），雷电的时延挺高，双卡跑起来效果就显著不如Occulink的PCIE直连了。不过我这个结论是参考的reddit，自己没有实测过。但Apple在MAC上给雷电添加了RDMA支持，就是为了降低时延，从这一点来看，雷电时延高会降低TP速度这个结论应该是比较靠谱的。</p>
