<p dir="auto">GIGABYTE MU72-SU0</p>
<p dir="auto">纠结点：<br />
【1】pcie4.0 和 pcie5.0 的选择<br />
【2】ddr5 价格是 ddr4 价格的两倍</p>
<p dir="auto">我想运行 qwen 3.8 flash 模型。也想以后能尝试一点其他模型。</p>
<p dir="auto">如果选择 GIGABYTE MU72-SU0 的话，我就能上到 512G 内存。<br />
如果选择 ASUS Pro WS WRX90E-SAGE SE 的话，我只能拥有 256G内存。</p>
<p dir="auto">希望大家能给一点建议。谢谢。</p>

<p dir="auto">服务器主板也是相对的便宜很多了，特别是意外发现的 EPYC 9B14 cpu。</p>

<p dir="auto">这个不要想，相同工艺，不可能你家又快又省电。  mac这么省电一定会有损失的地方。</p>
<p dir="auto">现在的商单看个乐。等私人到手后M5 ultra  啥水平就知道了。</p>
<p dir="auto">我看来看去感觉4卡R9700  才能干得漂亮 。</p>
<p dir="auto">虽然单卡R9700 跑MXFP4 的Qwen27B 已经非常好了。处于能用，爽用的级别。</p>
<p dir="auto">双R9700 会更爽一些的多并发。</p>
<p dir="auto">四卡R9700 + 超大内存，能跑一些flash 模型，向更实用迈进。</p>
