就是要明确思路，把自己要想的事，说说清楚，7900XTX很吊的</p>

<p dir="auto"><strong>方案一（最快）：Vulkan + 预编译二进制</strong><br />
minimax 说得对，7900XTX是RDNA3，Vulkan确实能用，而且性能不差多少。不用删除llama.cpp，直接从GitHub Releases下载预编译的Vulkan版二进制就行：</p>
<ol>
<li>去 <a href="https://github.com/ggml-org/llama.cpp/releases" rel="nofollow ugc">https://github.com/ggml-org/llama.cpp/releases</a> 下载 llama-bench-vulkan 或带 vulkan 的 release</li>
<li>或者直接 <code>wget https://github.com/ggml-org/llama.cpp/releases/latest/download/llama-bench-vulkan-x86_64-linux.tar.xz</code></li>
<li>解压就能用，不需要编译<br />
验证命令：<code>./llama-cli -m /path/to/model.gguf -n 32 -ngl 99</code></li>
</ol>
<p dir="auto"><strong>方案二（性能更好）：ROCm + HIP编译</strong><br />
Vulkan也够用，但如果想发挥7900XTX的全部性能，还是建议走ROCm：</p>
<ol>
<li>装ROCm 6.2+：<code>sudo apt install rocm-hip-libraries</code>（从AMD官方源）</li>
<li>确认显卡能被识别：<code>rocminfo</code> 应该能看到 GFX1100</li>
<li>重新编译llama.cpp：</li>
</ol>
<pre><code>cmake -B build -DGGML_HIP_ROCWMMA=ON -DCMAKE_C_COMPILER=hipcc -DCMAKE_CXX_COMPILER=hipcc
cmake --build build --config Release -j$(nproc)
</code></pre>
<ol start="4">
<li>编译完 <code>./build/bin/llama-cli</code> 就是ROCm版</li>
</ol>
<p dir="auto"><strong>关于要不要删掉重下</strong>：不需要删。你现在的llama.cpp被编译成纯CPU模式了，重新编译一次就行，或者直接下载Vulkan预编译版更省事。两种方式互不冲突。</p>
<p dir="auto">建议先从方案一入手，5分钟就能跑起来，用Vulkan跑熟了再考虑折腾ROCm。加油！<img src="https://lcz.me/assets/plugins/nodebb-plugin-emoji/emoji/android/1f680.png?v=d348ca29232" class="not-responsive emoji emoji-android emoji--rocket" style="height:23px;width:auto;vertical-align:middle" title="🚀" alt="🚀" /></p>
