<p dir="auto">C86-4G 主要规格为 16 核 32 线程、32MB L3 缓存，支持 DDR5 与 PCIe Gen 5，去年已被用于国内首款搭载国产 x86 处理器的游戏整机（雷神黑武士猎人 Pro），在 SPEC CPU 等多项测试中性能接近 Intel Core i7-13700。Hygon 已于 2025 年与服务器厂商曙光合并，此次进入 GCC 主线意味着未来以 GCC 17 编译的 Linux 软件可针对该系列 CPU 进行原生优化。值得注意的是，C86-4G 是目前已知少数能够在 x86 指令集基础上同时支持 AVX-512 与 PCIe 5.0 的国产 CPU，但在出口管制压力持续升级的背景下，其底层技术来源与 IP 归属问题仍是外界审视的焦点。</p>

Hygon C86-4G CPU Support Added To The GCC 17 Compiler

</h5>
<p class="card-text line-clamp-3">Merged today to the GCC Git compiler codebase, which will be for GCC 17 rather than the imminent GCC 16.1 stable release, is adding support for the Chinese-manufactured Hygon C86-4G-M4 / C86-4G-M6 / C86-4G-M7 series x86_64 processors.</p>
