戴尔 XPS 16 酷睿 Ultra X7 比酷睿 Ultra 5 声音更大、更耗电
ⓘ Notebookcheck
我们已经确定我们已经确定 XPS 16 Core Ultra X7 358H配置的速度明显更快，可以说，与配置较低的酷睿 Ultra 5 325 或酷睿 Ultra 7 355 相比，价格上涨是值得的。尽管如此，酷睿 Ultra X7 仍有一些缺点需要买家注意。
虽然所有 2026 XPS 16 SKU 都配备了相同的 100 W USB-C 交流适配器，但在运行苛刻负载时，酷睿 Ultra X7 SKU 的耗电量要比酷睿 Ultra 5 或 Ultra 7 配置高出大约 35%。不过，酷睿 Ultra X7 更高的性能水平抵消了更高的功耗，尤其是在图形性能方面。
Core Ultra X7 的散热解决方案与 Core Ultra 5 或 Ultra 7 完全相同，尽管功耗较高。因此，作为补偿，风扇噪音往往会更大。Core Ultra X7 配置中的双风扇更快地达到更高转速，比较低的非 X Core Ultra 配置中的风扇更明显。例如，在运行《赛博朋克 2077》时，风扇噪音会更快达到 38 dB(A)，而当 CPU 处于完全紧张状态时，甚至会达到更高的峰值，接近 49 dB(A)。
幸运的是，这些缺点只有在运行压力较大的工作负载时才会明显感觉到，因为所有配置在其他情况下都是静音的，而且在简单浏览网页或闲置时仍然非常省电。
