从表面上看,CPU 原始性能的同比优势微乎其微,但一旦考虑到节流因素,这种优势就会扩大,有利于英特尔的新 Panther Lake 系列。
Laptop / Notebook Intel Ultrabook Review Snippet Meteor Lake

英特尔将首次推出 Panther Lake-H 两款功能强大的 SKU,包括 酷睿至强 X7 358H酷睿至尊 X9 388H这两款产品旨在取代上一代 Arrow Lake-H 酷睿至尊 7 255H酷睿至尊 9 285H分别取代上一代 Arrow Lake-H Core Ultra 7 255H 和 Core Ultra 9 285H。虽然新的集成 Arc B390GPU 与 Arc 140T/140V 系列相比有了巨大的飞跃,因此获得了很高的评价,但相比之下,CPU 性能的更新换代却没有那么明显。不过,直接优势还是值得一提的。

从下面的对比图中可以看出 华硕 ExpertBook Ultra采用酷睿 Ultra X7 处理器,与其他采用较早的酷睿 Ultra 7 255H 处理器的 14 英寸笔记本电脑相比,性能更快、更稳定。这意味着华硕的 Turbo Boost 时钟频率可以持续更长的时间,而 Arrow Lake-H 超小型笔记本的 Turbo Boost 时钟频率则更有可能随着时间的推移而变慢。例如,循环运行 CineBench R15 xT 会在华硕上得到相对稳定的分数,而在联想 Yoga Book 9 上进行同样的测试则会得到相对稳定的分数。 联想 Yoga Book 9 14则会导致性能下降近 25%。

不过,更快、更可靠的性能是有代价的。当长时间运行高负载时,华硕的 Panther Lake CPU 会在 89 摄氏度左右达到峰值,明显高于大多数其他 14 英寸机型,后者的温度在 70 摄氏度到 80 摄氏度之间较为常见。此外,我们也不能保证未来采用 Panther Lake 处理器的机型也能像华硕一样保持性能,尤其是该处理器被设计为可在多种功率范围内动态运行,以适应多种屏幕尺寸。

预计今年第二季度将有更多搭载 Panther Lake 处理器的笔记本电脑上市,包括 焕然一新的微星 Prestige系列将成为引人注目的产品。在此之前,用户可以查看 我们对 ExpertBook Ultra 的评测的更多早期基准测试和比较。
