<p dir="auto">花了一个周末，让 OpenAI Codex 在它的基础上折腾了一轮，补上了 MiniMax-H3 Ref2VA FP8 的全引用支持，图片、动作视频、音乐可以混合输入，已经完整跑出了成品。</p>
<p dir="auto">这轮主要围绕 RDNA4 优化 GPU 算子、显存布局和双卡调度。在双 R9700 上，既把全引用流程跑通了，也明显缩短了实测生成时间，并完整的利用上了64G显存。</p>
<p dir="auto">当然，两张 RDNA4 只是这次的实测配置，这种优化思路还有向更多显卡扩展的空间。在主板 PCIe 通道、互联带宽和软件支持到位的前提下，可以把模型权重和计算任务合理分摊到不同显卡上，提高显存与算力的利用率。</p>
<p dir="auto">我觉得它的吸引力就在这里，通过多卡协作，让相对便宜的硬件也能承担一些原本需要大显存专业卡才能处理的任务，向 Pro 6000 那类显卡的任务承载能力靠拢。当然，实际速度还要看具体负载，显存容量相加也不等于性能直接相加。</p>
<p dir="auto">具体移植、优化和调试由 Codex 完成的，底子还是原作者的 Radiance，这次真的是站在了“巨人”的肩膀上了。</p>
<p dir="auto">先发个小预告，详细过程、性能对照和实验分支稍后整理。</p>
<p dir="auto">AMD 的硬件潜力确实还有得挖一下，就是生态需要多折腾... 趁现在还没反应过来，锤友们想搞的多买几张总不会错的。</p>
