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。

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。
Display Response Times
ℹ
Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.| ↔ Response Time Black to White | ||
|---|---|---|
| 19.3 ms ... rise ↗ and fall ↘ combined | ↗ 10.7 ms rise |  |
| ↘ 8.6 ms fall | ||
| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 37 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21.5 ms). | ||

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 34 % of all devices are better. This means that the measured response time is better than the average of all tested devices (33.7 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.| Screen flickering / PWM not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17903 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
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.

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%。

电池续航时间比以前延长了约半小时。我们可以记录下近 10 个小时的无线局域网实际使用时间，这与 Inspiron 14 7435 2 合 1 或宏碁 Aspire 5 Spin 14.
这次从空机充电到满电仅需 75 分钟，充电速度更快。

Cons
- 16 GB 内存升级价格昂贵
- 扬声器音量可以更大
- sRGB 覆盖范围有限
- 没有酷睿 i7 选项
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 。
