这不仅仅是因为价格:对于许多2026款笔记本电脑而言,消费者或许选择购买较早的2025款型号会更划算。联想ThinkBook 14 G9 IPL在性能上很难超越其前代机型。
Business Review Snippet Laptop / Notebook Zen 5 Panther Lake

基本上,现在大家都已经听说过内存和固态硬盘短缺的问题,这导致整个科技市场的价格普遍上涨。这使得所有个人电脑的价格大幅上涨,当然也包括笔记本电脑。 这意味着:如果你追求高性价比,那么在2026年购买笔记本电脑不会让你感到满意,或者说,这会导致你的银行账户所剩无几。

除了价格因素外,还有另一件事让购买2026年的笔记本电脑变得不那么吸引人。那就是功能上的退步,包括内存减少、SSD容量缩小或屏幕质量下降。但有时还包括CPU性能的退步。

一个典型例子:随着英特尔从2025年CPU世代——Lunar Lake和Arrow Lake——向2026年Panther Lake产品线的过渡,存在一些性能妥协。 首先是GPU性能:只有Core X7和X9系列中性能最强的Panther Lake型号才拥有更快的图形处理单元,而标准版Panther Lake的性能实际上甚至不如Arrow Lake或Lunar Lake。

英特尔Panther Lake:如今已不再是毫无争议的升级选择

其次,标准版八核Panther Lake在CPU性能上落后于Arrow Lake,仅能与Lunar Lake CPU系列持平——而许多人早已认为后者性能略显不足。

一个最近的例子就是 我们评测过的联想 ThinkBook 14 G9 IPL。其前代机型 ThinkBook 14 G8 IAL 搭载了 Arrow Lake 架构的英特尔酷睿 Ultra 7 255H 处理器,而我们此次评测的新款机型则搭载了英特尔酷睿 Ultra 5 325 处理器。 总体而言,较早款的联想笔记本在 CPU 性能上快了 32%,在 GPU 性能上快了 55%。

现在,新款机型运行时温度略低,电池续航时间也有所提升,但差异并不大——不过性能却明显下降了。当然,你可能会问:为什么不买一款搭载更快速CPU的新款ThinkBook呢? 遗憾的是,这款机型无法选配更快的H系列处理器,而且即便选配了,其显卡性能依然会更差。

除非你购买的是搭载英特尔X7或X9处理器的笔记本,否则今年很可能不得不接受性能的下降——而且还要为此付出高昂的代价。 即使避开英特尔,也无助于提升2026年笔记本电脑的吸引力:AMD只不过是给旧款CPU换了个新名字,这意味着产品停滞不前。
