最新机型配备的是 140 瓦 USB-C AC 适配器,而不是去年机型配备的 170 瓦适配器。幸运的是,性能并未受到负面影响。
Arrow Lake Business Laptop / Notebook Workstation Review Snippet

ThinkPad P1 16 Gen 8 是一款注重超薄便携性的移动工作站,同时还提供酷睿 Ultra H 性能和 Nvidia 独立显卡选项。它的外观设计和尺寸与去年的 ThinkPad P1 16 7 代但更新了内部结构,并采用了更新、更小的 USB-C AC 适配器。后者尤其有趣,因为更薄的适配器额定功率仅为 140 W,而去年的型号为 170 W。值得庆幸的是,性能似乎并没有受到较小功率上限的影响。

我们在 2025 ThinkPad P1 16 Gen 8 的评测中,我们发现 CPU 和 GPU 的性能都有所提高。的评测中,我们发现尽管使用了更小的交流适配器,但 CPU 和 GPU 的性能始终快于 2024 Gen 7 版本,如下图基准测试所示。需要注意的是,在运行苛刻的负载时,功耗与以前大致相同,这意味着即使是去年的 7 代机型也没有完全利用 170 W 的功率上限来提高性能。

不过,更大的 170 W 适配器有一个关键优势。当同时运行高负载时,ThinkPad P1 16 Gen 7 能够以更快的速度充电,因为更大的适配器为充电提供了电力开销。相比之下,在较新的 8 代机型上运行要求较高的负载时,耗电量已经达到 120 瓦至 140 瓦,几乎是 140 瓦 USB-C AC 适配器的全部容量。因此,如果 CPU 长时间处于忙碌状态,充电速度就会减慢。不过,就大多数旅行和使用目的而言,我们更喜欢通用的 USB-C 交流适配器,而不是较旧 ThinkPad 机型上标配的较重的专有适配器。
