Panther Lake XPS 16 非常高效，空闲时功耗仅为 1.5 瓦，电池寿命超长
ⓘ Notebookcheck
2026 XPS 16 为该系列带来了内外两方面的重大变化。在内部，戴尔放弃了 Arrow Lake 和 NvidiaGeForce 选项，只采用 Panther Lake。通过放弃独立显卡，戴尔既能缩小机身，又能大幅提高能效。
下图显示了 XPS 16 FHD+ 配置在最低亮度设置和启用 VRR 的情况下，在桌面上空转两分钟的功耗。该系统的平均功耗仅为 1.5 瓦，这对于 16 英寸大屏幕来说非常可观。竞争机型如 华硕 ZenBook S16或 微星 Prestige 16等竞争机型在类似条件下的功耗都在 3 瓦到 5 瓦之间。
如果将新款 XPS 16 的亮度从最低调至最高，平均功耗将从 1.5 瓦增至 4.5 瓦，但仍远低于许多竞争对手。
当然，Panther Lake 的高效率可以显著延长电池寿命。例如，我们的测试设备在启用 VRR 并将亮度设置为 150 尼特的平衡功耗配置文件下进行 WLAN 循环测试时，可持续使用近 27 个小时。即使考虑到新款 XPS 16 配备了较小的 70 Wh 电池，测试结果也比上一代 XPS 16 机型轻松延长了几个小时。
尽管如此，新款 XPS 16 的所有变化还是带来了一些明显的缺点，尤其是在图形性能方面。更多基准测试和比较可参见我们的 最近对 2026 XPS 16 的评测.
