机箱 - Slim 7，全铝机箱
Yoga Slim 7 14 G8 的机身完全由铝合金制成，底座周围最圆润、最光亮的边缘设计与去年的Yoga Slim 9.当你使用这款笔记本电脑并将其随身携带时，你会发现它的盖子非常纤薄。与其他现代联想笔记本电脑类似，它也有一个摄像头凸起，看起来并不十分美观，但它能让你更轻松地打开盖子，单手就能完成。边框非常窄，整体设计很现代。联想为 Slim 7 14 提供银色和茶色两种颜色。在我们的评测期间，银色机身的磨砂表面对灰尘和指纹的抵御能力很强。由于键盘也是银色的，所以没有太多视觉上的亮点，只有黑色的边框很显眼。
总之，这款笔记本电脑给人的感觉很高档，稳定性也没有问题。我们无法扭转底座，也没有嘎吱嘎吱的声音，只有中间的键盘区域在受力时会有明显的推入感。不过，这在日常打字时应该不成问题。薄薄的盖子也相当坚固，但铰链跟不上。盖子很轻，但在调整打开角度（最大 180 度）时仍会有一些晃动，尽管铰链能在很小的角度下牢牢地将盖子固定到位。
新款 Yoga Slim 7 14 仅有 13.9 毫米，是我们对比组中最薄的设备之一，仅次于当前的 MacBook Air M2。由于采用了更大的 14.5 英寸屏幕，因此评测机和 Yoga Pro 7 都是最大的设备。超薄 7 14 的重量为 1.3 千克，比 Yoga（超薄）Pro 7 还要轻。瑜伽（超薄）Pro 7轻，仅次于 13.6 英寸的MacBook Air M2.65 瓦的电源适配器仅重 312 克。
连接性 - AMD Yoga 配备 USB 4
Yoga Slim 7 的端口情况与更昂贵的Yoga Slim 9只提供 USB-C 端口。左侧的两个接口支持高达 40 Gbps 的 USB 4，右侧的 USB 3.2 Gen.2 支持 10 Gbps。所有三个端口都支持电源传输和 DisplayPort 连接。不过，这意味着你可能时不时需要一些适配器。笔记本电脑Yoga Pro 7配备了额外的 HDMI 和 USB-A 接口，在这方面无疑更具优势。与 Yoga Slim 9 相反，Slim 7 的包装盒中没有 USB 集线器。
交流
联想为 Yoga Slim 7 14 使用了 Realtek 的 Wi-Fi 适配器（8852CE），它支持现代 6 GHz 网络（Wi-Fi 6E）和蓝牙 5.1。结合华硕的参考路由器，我们可以获得非常高且稳定的传输速率。Yoga 的传输速率在 1.7-1.9 Gbps 之间，是这方面速度最快的设备之一。

网络摄像头
联想采用了标准的 1080p 网络摄像头，在光线条件良好的情况下也能拍出不错的照片。显然，你不应该指望一个 200 万像素的网络摄像头能创造什么奇迹，但它能完成自己的工作。机身右侧有一个 eShutter 按钮，还有一个红外模块用于通过 Windows Hello 进行面部识别。
维护
下面板由几颗 Torx 螺钉（T5）、额外的塑料夹和一个额外的夹子固定，夹子位于设备中心（您可以看到电池上部的对应部分）。这意味着拆卸面板并不容易。除了清洁风扇或更换 M.2-2280 固态硬盘和 Wi-Fi 模块外，没有什么可做的。内存是焊接的，无法更换。
输入设备 - 1.5 毫米行程和可选触摸屏
Yoga Slim 7 14 G8 的键盘也是银色的，这就造成了白色背景照明（两级）的问题。如果天还没有完全黑下来，设备会自动激活照明（通过传感器，也可以手动开启），那么按键和字体之间几乎没有任何对比度。我们已经批评过老款微软 Surface 设备的这个问题。茶色版本在这方面应该有优势。
输入体验本身非常舒适，1.5 毫米的键程和精确的按键敲击让人倍感舒适。键盘也非常安静，只有较大的空格键声音稍大。与Yoga Pro 7一样，这也是一款非常出色的键盘，输入较长的文字也不成问题。
宽大的点击板（13.5 x 8 厘米）为多达四个手指的多点触控手势提供了充足的空间，并具有良好的滑动功能。我们在光标控制方面没有遇到任何问题。你可以用物理方式点击下半部分的触控板，这样会发出很大的声音，显得有点廉价。我们的评测机没有触摸屏，但 Yoga Slim 7 14 G8 可以选配触摸屏。
显示屏 - 14.5 英寸 OLED，90 赫兹
迄今为止，Yoga 机型通常配备的是 2.8K OLED 屏幕，存在轻微摩尔纹效果的问题，尤其是在明亮的内容和屏幕距离较短的情况下。新款 Yoga Slim 7 14 G8 是首款配备全新 14.5 英寸 2.9K OLED 的设备，其分辨率高达 2944 x 1840 像素（16:10）。屏幕非常光亮，但不支持触摸输入。
让我们来谈谈画质，我们一眼就能看出，新的 OLED 面板没有出现之前提到的摩尔纹效应。主观画质非常出色：内容清晰锐利，色彩非常鲜艳，对比度极高，因为黑色内容就是黑色。90 Hz 的较高频率也使画面的移动受益匪浅。
不过，新型 OLED 的亮度没有那么高。SDR 值在 390 尼特左右完全没问题，而其他 OLED 竞争对手通常只能达到 340-370 尼特，但 HDR 效果却令人失望。联想宣传在 HDR 模式下可达到 500 尼特，但我们只能达到 435 尼特，这意味着 HDR 功能有限。Windows 的 HDR 实现也仍然是个问题，因为你必须手动激活 HDR 模式，这也意味着 SDR 内容仅限于 sRGB，而且看起来比预期的要苍白一些。黑色值为 0，这意味着最大对比度极高。OLED 屏幕没有背光出血现象，响应时间非常快。

* ... smaller is better
我们使用专业的 CalMAN 软件结合 X-Rite i1 Pro 2 分光光度计进行分析。预装的 Vantage 应用程序提供四种不同的色彩配置文件：默认、sRGB、P3、AdobeRGB。默认配置文件在默认情况下处于激活状态，但色彩有点过饱和。显示器应该覆盖 P3 色域，因此我们使用相应的 P3 配置文件进行评分。
P3 配置文件开箱后已经非常精确，灰度和色彩与 P3 参考色彩空间相比，DeltaE2000 偏差都不超过 3，因此用户无需进行校准。只有色温略微偏高。我们无法通过自己的校准来进一步提高图像质量，因此目前还没有提供相应的配置文件。
当你想在较小的 sRGB 色彩空间中工作时，sRGB 配置文件也非常有趣。相应的配置文件同样非常精确，而且限制了色彩空间，因此也可以编辑图片和视频。而 AdobeRGB 配置文件则没有太大意义，因为它的 AdobeRGB 色域只覆盖了 87%。

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 360 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 360 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 360 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||
在所有亮度水平下，我们测量到该面板的 PWM 频率为 360 Hz。不过在高亮度下振幅很低，我们必须放大测量值才能检测到。PWM 闪烁是肯定存在的，如果你对它很敏感，你就不会对这块屏幕感到满意。与华硕的 Zenbook S 13 相比，联想还需要努力。Zenbook S 13例如 Zenbook S 13）相比，联想还需要努力，因为华硕使用了直流调光技术和软件解决方案来解决低亮度时的 PWM 闪烁问题。
由于 OLED 屏幕表面非常光亮，因此户外可用性非常有限。我们的示例图片很好地说明了这个问题。在阴天应该能找到合适的位置，但在阳光普照的时候就难多了。OLED 面板的视角稳定性非常好，只是在极端角度下会出现轻微的蓝色。不过，这在实际使用中并不重要。
性能 - AMD Zen4 Phoenix
我们已经提到，新款 Yoga Slim 7 14 G8 配备了 35W 处理器，来自 AMD 当前的 Phoenix 代 Zen4 内核。用户可以选择 Ryzen 5 7560S 或Ryzen 7 7840S但规格与相应的 HS 系列芯片相同。Ryzen 5 只配备 16 GB 内存，而 Ryzen 7 则可配备 16 或 32 GB 内存（LPDDR5x-6400，焊接）。图形处理器由集成 GPU 处理Radeon 760M或780M.
审查设置
预装的 Vantage 应用程序提供不同的电源配置文件，可通过组合键（Fn+Q）进行切换。高性能"、"智能散热 "和 "电池节能 "三种配置文件的 TDP 范围在 12-52 瓦之间，差异很大。我们在下表中列出了详细数值：
| 模式 | CPU 负载 | Cinebench R15 Multi | Time Spy 图形 | 最大风扇噪音 |
|---|---|---|---|---|
| 电池保护器 | 20 -> 12 瓦 | 1006 分 | 1725 分 | 32.9 分贝(A) |
| 智能冷却 | 40 -> 30 瓦 | 2223 分 | 2814 分 | 42.5 分贝(A) |
| 高性能 | 52 -> 42 瓦 | 2475 分 | 2865 分 | 45.5 分贝(A) |
在以下基准测试和测量中，我们默认使用高性能模式。在日常情况下，您可以轻松切换到智能冷却模式，因为它仍能提供强劲的性能，但风扇噪音更小。
处理器 - Ryzen 7 7840S
......（英文AMD Ryzen 7 7840S是联想产品的专属型号，但它基本上是Ryzen 7 7840HS.这款处理器的功耗为 35W，配备 8 个现代 Zen4 内核，主频高达 5.1GHz，最多可同时执行 16 个线程。唯一的区别似乎是联想可以使用的 TDP 范围更广。例如Ryzen 7 Pro 7840HS在HP EliteBook 845 G10的 Ryzen 7 Pro 7840HS 在最高效模式下的功耗仍高达 35 瓦，而联想的功耗仅为 12 瓦。
在高性能模式下，该处理器的功耗可高达 52 瓦，然后降至 42 瓦。这意味着多核性能比目前的酷睿 i7-13700H在申克 Vision 14(45/40 瓦）相比，多核性能要好得多，但也比老式的酷睿 i7-1280P（52/35 瓦）快得多。Yoga Slim 9 14.在多核测试中，最接近的竞争对手是Yoga (Slim) Pro 7配备了Ryzen 7 7735HS(Zen3+），但该处理器的功耗也更高（60/50 瓦）。
Cinebench R15 Multi Loop
在单核基准测试中，Zen4 芯片比 7735HS（Zen3+）快约 10%-13%，但在大多数测试中仍被英特尔芯片的高性能内核击败。不过，差距已经不大。
该处理器的电池功耗为 45/40 瓦，因此多核性能仅下降了约 4%。更多 CPU 基准测试可在我们的 技术部分.

图形处理器性能 - Radeon 780M
所有图形均由集成的 Radeon 780M 处理，与 Ryzen 7 7840S 结合使用时，主频可达 2.7GHz。iGPU 的性能还得益于双通道配置的快速 LPDDR5x-6400 内存。这是迄今为止我们评测过的最快版本的 Radeon 780M。合成基准测试表明，780M 比目前配备 96 个 EU 的 Iris Xe Graphics G7 快约 50%，但在 Wildlife Extreme Unlimited 测试中，Apple 配备 10 个内核的 M2 GPU 仍然快 25%。在 OpenCL 基准测试中，AMD 的 iGPU 速度更快。
我们的标准游戏基准测试再次显示 Yoga Slim 7 14 G8 领先于竞争对手，许多老游戏都可以在 1080p 的高设置下进行。而《赛博朋克 2077》等现代游戏只能在低细节下流畅运行。
在较长时间的工作负载中，图形性能保持稳定，在Time Spy 压力测试（98.8%）和我们的Witcher 3 循环测试中都是如此，在电池电量方面也是如此。更多 GPU 基准测试 这里.

系统噪音
Yoga Slim 7 14 的两个风扇在空转和轻度工作负载时通常是静音的，但在 28 dB(A) 左右时会有轻微的杂音。一旦开始对处理器施加更大的压力，声音就会很快变大，尤其是在高性能模式下，这也显示了超薄机身与快速 Ryzen 处理器结合的缺点。风扇的噪音最高可达 45.5 dB(A)，但频率并不恼人。在其他两种模式下，笔记本电脑明显更安静，下表显示了不同配置文件下的结果。我们的评测机没有显示任何其他电子声音的迹象。

温度
Yoga Slim 7 14 G8 的表面温度在空载和轻度工作负载时没有问题，但负载再次显示了纤薄机身与快速处理器结合的妥协。键盘中/上部的温度高达 42 °C，这在打字时很明显，但没有任何限制。更大的问题在于处理器区域的底部。我们测得的温度超过 55 °C，因此应避免皮肤接触。
在 CPU/GPU 负载的压力测试中，最初几分钟的功耗为 43 瓦，之后降至 40 瓦左右。压力测试结束后，我们没有发现性能立即下降。

能源管理 - 电池运行时间长和 PSU 不足
耗电量
OLED 屏幕的闲置功耗在很大程度上取决于所显示的内容，因为更高的图像需要更多的电量。与竞争对手的 IPS 屏幕相比，Yoga Slim 7 的耗电量较高，但与去年的 2.8K OLED 屏幕相比，我们看到了明显的优势。Yoga Slim 9 14.我们的负载测试清楚地表明，65 瓦的电源适配器是不够的。在我们的压力测试中，耗电量锁定在 67 瓦，这是电源适配器的极限。在一小时的压力测试中，CPU 的消耗量发生了变化，电池百分比下降了 3%。使用智能散热模式时没有问题，但如果有高性能模式，制造商应确保电源适配器足够用，Yoga Slim 7 14 应该配备 90 瓦的电源适配器。

电池运行时间
70 Wh 的电池提供了不错的续航时间，但与 IPS 竞争对手相比，Yoga 仍然很吃力。在 150 尼特（最大 SDR 亮度的 67%）和 60 Hz 的条件下进行的 Wi-Fi 测试结果为 9.5 小时左右，比去年的Yoga Slim 9 14.全亮度下的 Wi-Fi 测试时间为 7.5 小时，视频测试（同样为 150 尼特）时间约为 11.5 小时。90 Hz 下的运行时间较低，我们在下表中列出了结果：
| 模式 | Wi-Fi 测试（150 尼特） | Wi-Fi 测试（最大亮度） | 视频测试（150 尼特） |
|---|---|---|---|
| 60 赫兹 | 571 分钟 | 444 分钟 | 690 分钟 |
| 90 赫兹 | 539 分钟 | 418 分钟 | 649 分钟 |
总之，对于一款高分辨率 OLED 屏幕（也比大多数同类设备大一些）来说，效果非常不错，但你不要忘了，一些竞争对手的屏幕寿命要长得多。其中包括申克 Vision 14等机型，尤其是Yoga Pro 7 14以及稍小的MacBook Air M2的运行时间超过 13 小时（有时甚至更长）。
如果以全亮度观看 HDR 视频，运行时间仅为 3 小时多一点（196 分钟），在高性能模式下，满负荷运行 1 小时多一点即可耗尽电池。设备开启后，完全充电需要 120 分钟，68 分钟后可获得 80% 的电量。

结论 - Yoga Slim 7 14 图像质量出色，性能强劲
目前，联想推出了大量配备 14 英寸显示屏的非常出色的超极本/多媒体笔记本电脑，新款 Yoga Slim 7 14 G8 也不例外。与 Yoga Pro 7 相比，它的机身更薄，缺少 HDMI 或 USB-A 等接口，但也配备了 AMD 最新的 Zen4 处理器和全新的 2.9K OLED 屏幕。
处理器Ryzen 7 7840S处理器是联想笔记本电脑独有的，但我们没有发现它与普通的Ryzen 7 7840HS.只有最低 TDP 可以设置为低于 35 瓦，因此联想对电源配置文件的影响更大，这一点也是显而易见的。在高性能模式下，性能表现非常出色，尤其是多核性能要优于该 TDP 范围内的现代英特尔 CPU，但我们也不得不说，纤薄机箱中的散热解决方案很难与强大的处理器相抗衡。如果你真正使用处理器的性能，风扇很快就会发出很大的噪音，机箱也会变得很热。显然，你可以使用更高效的电源配置文件，但就散热性能而言，U 系列处理器会是更合适的选择。
铝制机箱本身给人留下了非常好的印象，而且非常坚固，你会立刻注意到纤薄的盖子。铰链可以再坚固一些，银色的键帽与白色背景照明之间的反差不大。键盘本身提供了非常舒适的键入体验。联想还为机身配备了 6 扬声器音响系统，这在同类产品中是最好的。
新款联想 Yoga Slim 7 14 G8 是一款非常出色的子笔记本，配备了强大的 AMD Zen4 处理器，但对散热方案也是一个不小的挑战。全新的 2.9K OLED 屏幕相比上一代质量有所提升，但由于最大亮度相对较低，HDR 功能受到限制。
新的 2.9K OLED 屏幕总体上给人留下了不错的印象。旧版 2.8K 屏幕的摩尔纹效果问题已经不复存在，联想还提供了非常准确的 P3 和 sRGB 色彩配置文件。不过，也存在一些问题，如 HDR 最高亮度较低以及 PWM 不断闪烁。华硕用自己的 OLED 笔记本展示了如何在这方面做得更好。尽管如此，这并不能改变画质出色的事实，而在实际使用中，光面是一个更大的问题。
对于 OLED 设备来说，电池续航时间非常不错，但 IPS 竞争对手的续航时间更长。最大的竞争对手之一是联想自己的Yoga Pro 7采用 Zen3+ 芯片，速度并不慢，但 IPS 面板不使用 PWM，电池运行时间明显更长。还有一款配备独立GeForce RTX 4050 笔记本电脑，其图形性能要高得多。华为的MateBook X Pro也是一款非常不错的替代产品，但价格要贵得多。如果你更喜欢没有风扇噪音的小巧设备，那就不能错过MacBook Air M2尽管它的配置（1 TB 固态硬盘、24 GB 内存）也更贵。申克申克 Vision 14拥有更好的维护选项、更多的端口和更长的电池续航时间，但速度稍慢，价格也更贵。
