交流
有趣的是,联想将去年型号上的英特尔 AX201 换成了 RealTek RTL8852BE,这可能是为了降低成本。如下图所示,RealTek 模块的性能较慢,但传输速率稳定可靠。目标受众是普通家庭用户或学生,他们可能不会注意到两者之间的差异。

维护
底部面板很容易拆卸,显示出 2022 和 2023 型号之间没有重大的内部差异。
显示屏
今年的显示屏没有任何变化,甚至没有其他面板可供选择。令人遗憾的是,sRGB 的覆盖范围有限,但如下表所示,这也是经济型可转换产品的典型特征。

面板开箱后的校准效果很差,这对于一款经济型笔记本电脑来说是意料之中的。色温过高,色彩准确度也因此受到影响。使用我们的 X-Rite 色差计进行适当校准后,灰度和色彩会有明显改善,但由于前面提到的 sRGB 覆盖范围较窄,高饱和度的色彩仍然不准确。我们的校准 ICM 配置文件可在上面免费下载。

性能
测试条件
在运行下面的基准测试之前,我们将 Windows 和联想 Vantage 都设置为性能模式。无论好坏,Vantage UI 与去年相比都进行了全面修改,因此用户需要重新学习所有新的子菜单和重新定位的设置。
处理器
第 13 代 酷睿 i5-1335U与第 12 代 酷睿 i5-1235U的性能优势微乎其微。它的主要优势在于更快的 Turbo Boost,在启动应用程序或编辑图片时可以派上用场。如下图所示,我们的 CineBench R15 xT 分数在首次运行后会下降 18%,因为 Turbo Boost 时钟速率不是无限的。
升级到 酷睿 i7-1355U配置预计只能将处理器性能提升几个百分点。 ThinkPad X1 Yoga G8.

2023 型号采用了与三星 PM9B1M.2 2242 NVMe 固态硬盘。与价格更高的 PM9A1 不同,PM9B1 是一款中端 PCIe4 x4 固态硬盘,传输速率只有后者的一半左右,对于酷睿 i5 U 系列处理器来说仍然绰绰有余。不过,正如我们在下面的 DiskSpd 循环测试结果所示,在几分钟的压力后,性能仍会下降,这与我们在去年的型号上观察到的情况类似。

图形处理器性能
2023 Flex 5 14 中集成的 Iris Xe 80 EUs 比 2022 机型中的相同 GPU 快 5%,但从实际效果来看,这种差异并不明显。要想在性能上有更明显的提升,用户就必须考虑联想 Yoga 7-14 等更昂贵机型上的 Radeon 680M 或 780M 竞争产品。
根据我们对 ThinkPad X1 Yoga G8 的使用情况,升级到配备 Iris Xe 96 EU 的酷睿 i7-1355U 配置有望将图形性能提升 15%至 20%。

正如我们下面的压力测试部分所显示的,尽管处理器温度比去年的机型低得多,但风扇噪音并不比去年的机型大。不过,在浏览网页或视频流时,风扇偶尔还是会在静音和 28 dB(A)之间跳动。30 分贝(A)的低噪音范围还不足以造成困扰,但脉动会让人更加明显。

Pros
Cons
评语 - 值得尊敬的小改动,昂贵的 16GB 升级
2022 和 2023 型号的主要区别在于后者采用了更新的第 13 代英特尔 CPU,其性能更快、每瓦性能更高,电池续航时间也更长,只是略有优势。在实际使用场景中,这些优势并不明显,因此考虑使用 2022 型的用户不会有太大损失。
对于大多数家庭用户和多媒体播放用途来说,2022 型号可以提供与物理上相同的 2023 型号基本相同的性能和体验,而且价格更低。
IdeaPad Flex 5 14 比较令人失望的地方在于它缺乏显示屏选项和昂贵的内存升级。虽然我们明白,sRGB 的覆盖范围在经济型笔记本电脑上通常是有限的,但无论如何,一些新的选项本可以帮助新款机型更好地区别于旧款机型。至于内存,联想目前没有提供从 8 GB 升级到 16 GB 的简单途径。例如,最便宜的 8 GB SKU 售价仅为 605 美元,而最便宜的 16 GB SKU 售价为 840 美元。由于酷睿 i5-1335U 的性能与价格更高的酷睿 i7-1355U 非常相似,因此高端产品的性价比大幅下降。因此,最好等待 16 GB 配置的促销,或者选择与基本相同的 2022 型号 。
