任天堂Switch 2芯片首次曝光！搭载NVIDIA Tegra239支持DLSS
快科技4月24日消息，任天堂Switch 2的核心芯片终于揭开了神秘面纱，有网友首次曝光了一张内部芯片的实拍图，确认其搭载了NVIDIA为其定制的Tegra239处理器。
这也延续了任天堂与NVIDIA的合作传统，此前的Switch也采用NVIDIA的Tegra X1芯片。
根据此前的消息，Tegra239芯片拥有8个Arm Cortex-A78C核心，GPU部分融合了Ada Lovelace和Ampere，拥有1536个CUDA核心，理论性能相较前代有显著提升。
CPU主频预计在1.1GHz至1.5GHz之间浮动，具体取决于掌机或底座模式的运行状态，此外，该芯片还支持128位的LPDDR5内存接口，提升了带宽与功耗效率。
最主要的是Tegra239原生支持NVIDIA DLSS ，能够在较低分辨率下运行游戏的同时，输出接近4K的画质表现，大幅提高运行效率与画面体验。
得益于此，Switch 2具备了底座模式实现4K/60FPS输出的能力，这是前代产品难以实现的画质提升。
目前官方仍未公布Tegra239的完整参数，更多信息仍需等待后续拆解或进一步披露，此前有传闻称NVIDIA将与联发科合作，推出面向AI PC的N1/N1X SoC，但目前仍未见正式亮相。
