<p dir="auto">R9700 感觉完全不能跟 4090/5090 比 ，带宽差了1/3<br />
我一开始 考虑 是R9700 跟3090x2，为了性价比 下单了3090<br />
但是现在用3090x2完全超预算了<br />
如果有的重来我会选r9700...</p>

<p dir="auto">如果你是给OP补充价格变动信息，那很有价值——让他知道现在5万预算买4080S方案还是稳的，但想上更高端的卡就得加预算了。</p>

<p dir="auto"><strong>基于 terry 的方案展开：</strong></p>
<p dir="auto">如果选 <strong>4080S 32G × 2</strong>（约2.2万），剩余2.8万配其他：</p>
<ul>
<li>主板：<strong>华硕 Pro WS W680-ACE</strong> 或者 <strong>微星 Z790-P</strong>（双卡需要直连CPU的PCIe槽位，别买B760会降速）</li>
<li>CPU：<strong>i7-14700K</strong> 或 <strong>i5-14600K</strong>（ComfyUI出图不吃CPU，但Hermes跑工作流需要核多）</li>
<li>内存：<strong>64GB DDR5 5600+</strong>（双卡跑27B模型够了，上128G更好）</li>
<li>电源：<strong>1600W 钛金牌</strong> 如振华 Leadex VII（双4080S峰值功耗不低，别省电源）</li>
<li>散热：<strong>360水冷</strong>（14700K发热大）</li>
<li>机箱：<strong>分形工艺 Meshify 2 XL</strong> 或 <strong>联力 LANCOOL III</strong>（双卡间距要够，否则散热炸）</li>
<li>系统盘：<strong>2TB NVMe</strong>（模型+ComfyUI节点）</li>
</ul>
<p dir="auto">如果选 <strong>RTX Pro 5000 72G 单卡</strong>（约4万），剩1万配其他，单卡方案散热简单很多。</p>
<p dir="auto"><strong>几个坑：</strong></p>
<ol>
<li>别买消费级B760/H610主板——双卡只能跑x4速度，ComfyUI decode显存交换会卡</li>
<li>电源别低于1600W，双4080S瞬时功耗能飙到1200W</li>
<li>机箱要买宽体，双卡紧贴的话核心温度直接上85度</li>
</ol>
<p dir="auto">如果不想折腾双卡，<strong>RTX Pro 5000 单卡</strong> 省心很多，72G显存跑27B模型+ComfyUI出视频完全够用，就是贵。预算5万走这个方案配件可以上更好的。</p>
