联想IdeaPad 5 15ALC05在审查。 15.6英寸的笔记本电脑让人信服并感到惊喜

想法(l)Pad?

联想IdeaPad 5 15ALC05以不到1,000欧元（约1,174美元）的价格提供了强大的CPU/GPU组合和大电池，但它在测试中也令人惊讶，与它的14英寸姐妹型号相比，有几点批评。我们的审查揭示了15.6英寸笔记本电脑的确切优势和弱点。
AMD Lucienne (Zen 2) Laptop / Notebook Ryzen (Zen) Windows

联想IdeaPad 5 15ALC05配备了AMD Ryzen 5500U，包括AMD Radeon RX Vega 7GPU。此外，还有16GB的DDR4 SDRAM的双通道模式和512GB的SSD存储。因此，其配置在许多方面与14英寸IdeaPad 5 14ALC05相同。我们对IdeaPad 5 15ALC05的评测将阐明除显示屏对角线尺寸外的其余差异。

此外，审查样本必须与其他15.6英寸的对手竞争，如联想ThinkPad L15 G2 ，采用AMD Ryzen 5600U，以及 宏碁Aspire 5 A515-56-511A，采用Intel Core i5-1135G7。

外壳。有品位且相对较轻的铝制笔记本电脑

联想IdeaPad 5 15ALC05的设计是简单明了的。该设备采用灰银色的铝制外壳，仅在材料的选择上就给人留下了高质量的印象，这在手感上也可以得到证实。只有显示屏的黑色塑料边框有点破坏了画面。

做工方面没有批评的余地；所有的缝隙尺寸都是你所期望的那样。非常宽的铰链在打开和关闭盖子时相对坚硬。然而，显示屏晃动了相当长的时间。

除了Honor MagicBook 15

，联想IdeaPad 5 15ALC05是15.6英寸对比机型中最轻的。它的重量约为1.7公斤。连同电源适配器，当笔记本电脑被带在路上时，需要运输2公斤的东西。

在尺寸方面，该设备也不必避开其竞争对手。只有14英寸，联想IdeaPad 5 14ALC05（如预期）明显较小。大多数15.6英寸机的尺寸是几毫米，有时甚至多出几厘米。

连接性。基本的东西都在船上

联想IdeaPad 5 15ALC05提供了在这个价格范围内你应该期待的基本连接。三个USB端口沿左右两侧分布。

有一个用于外部显示器的HDMI输出，以及通过单个USB-C端口的DisplayPort。这是批评的焦点之一，因为这个端口也被用于充电。换句话说，当笔记本电脑插入时，没有其他USB-C设备可以在不借助于附件的情况下连接。

LAN、Thunderbolt和Kensington都不包括在内。然而，有一个读卡器作为回报。由于彼此之间有足够的空间，所有端口都很容易到达。

SD卡阅读器

结合我们的64GB东芝Exceria Pro SDXC UHS-II参考存储卡，该读卡器几乎可以说是完全失败。它是测试领域中最慢的。这绝对是令人惊讶的，因为14英寸的姐妹机型连同相同的东芝卡在对比机型中达到了最好的速率，这表明东芝知道该如何做。该设备适合于传输一些照片。然而，在传输大量数据时，你应该准备好不必要的漫长等待时间。

联想IdeaPad 5 15ALC05在我们的Wi-Fi评测中也没有真正切入细微的数据。它在这里的排名也远远落后，但至少它在发送数据时仍能达到比RealTek的内置Wi-Fi模块的平均水平更好的速率。像IdeaPad 5 14ALC05，也提供新的Wi-Fi 6 / WLAN轴的竞争对手，与英特尔Wi-Fi 6 AX200或AX201，在这里表现得更好。

网络摄像头

虽然网络摄像头只有通常的720p分辨率，但它在测试中给人的印象要好得多。它的平均ΔE值在比较领域中排名第二，仅次于Honor MagicBook 15 ，因此它的色彩捕捉效果相当好。从竞争情况来看，在高清摄像头方面也没有什么可抱怨的，所以没有什么能阻碍联想IdeaPad 5 15ALC05的视频通话之类的。

同样实用的是，摄像头可以用机械快门挡住。这应该为某些用户提供更好、更安全的感觉。

辅料

除了65瓦的电源适配器外，联想并没有为IdeaPad 5 15ALC05提供任何其他配件。制造商在其在线商店中提供可选配件，如扩展坞。这也可以帮助解决缺乏USB-C端口的问题。

维护

底部的九颗细小的Torx螺钉阻止了进入内部的通道。然而，由于是焊接的RAM，内部没有多少升级选项。

担保

联想在德国提供通常的24个月制造商保修。

输入设备。大的按键和窄的数字键盘

键盘

15.6英寸的显示屏对角线和基本单元左右仅约1.5厘米的边距为联想提供了足够的空间来容纳一个足够大的键盘和一个挤在旁边的数字键盘，尽管机箱相对紧凑。后者将该设备与其较小的同类产品区分开来，联想IdeaPad 5 14ALC05 。

单个字母键的尺寸约为16×16毫米，因此与标准PC键盘的尺寸差不多。F1至F12键有通常的双重任务，用于调整显示器亮度或音量，也用于启动计算器。此外，还有一个两段式背光，以及一个集成在数字键盘上方最右边的细长电源按钮中的指纹传感器。

总的来说，在我们的测试中，键盘很快就提供了良好和熟悉的打字体验。在打字过程中，噪音水平也被控制在一定范围内。即使是空格键，在许多笔记本电脑中也是相当响亮的，但在联想IdeaPad 5 15ALC05中，当你非常用力地敲击它时才会变得更响。

触摸板

触摸板的尺寸约为10.5 x 7厘米，大小适中；它位于空格键下方的中心位置，因此略微偏向机箱的左侧。它给人留下了坚实的印象。除了相当响亮的点击噪音，在底部区域发现的非分离式点击面的右侧有时会产生轻微的吱吱声。然而，这也可能是我们测试设备的问题。

显示揭示了测试中的弱点

联想在IdeaPad 5 15ALC05中安装了一个内部制造的15.6英寸IPS面板，分辨率为全高清（1920x1080像素）。该显示屏是不反光和哑光的，这一点我们将在下面详细讨论。

首先，我们要看一下我们在审查联想IdeaPad 5 15ALC05时确定的测量结果。

几乎没有屏幕渗漏。当涉及到响应时间时，该面板的得分比竞争对手要高。然而，这在 "非游戏笔记本电脑 "中并不那么具有决定性。否则，不幸的是，也有几个批评的地方。该显示器的色彩空间覆盖率很低，只有59%的sRGB和38%的AdobeRGB。这对于想要进行专业或半专业图形编辑或类似工作的用户来说是不够好的。

显示器的亮度是可敬的，最大为376cd/m²。然而，它在边缘处明显下降，这导致了最差的亮度分布率。联想IdeaPad 5 15ALC05在黑色水平、对比度和色彩再现方面的测试和对比机型中也表现不佳。简而言之：联想IdeaPad 5 15ALC05在这里的竞争者中拥有最差的显示屏。

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.

The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 35 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (32.8 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 8710 (minimum: 5 - maximum: 343500) Hz was measured.

性能。笔记本电脑有足够的动力满足日常使用

我们评测的联想IdeaPad 5 15ALC05的配置（82LN0035GE）配备了AMD Ryzen 5500U 和AMD Radeon RX Vega 7 图形单元，以及双通道模式的16 GB DDR4 SDRAM和512 GB SSD。另外，联想还提供IdeaPad 5的其他配置，如采用相同的CPU/GPU组合，只有8GB的内存（82LN0034GE），例如。

事先的简短信息。联想在其Vantage软件中提供了三种不同的能源配置文件。我们大多使用 "智能冷却 "模式进行基准测试。与 "高性能 "相比，在测量结果中没有发现明显差异。

处理器

内置的AMD Ryzen 5 5500U是一个六核处理器。它的基本时钟速度是2.1GHz，通过Turbo可以运行到4GHz。该CPU支持SMT/超线程（12个线程），但它不像Ryzen 5600U那样基于新的、更快的Zen 3架构。相反，这两个APU都是基于Zen 2架构，这意味着除其他因素外，L3缓存较少。

正如预期，联想IdeaPad 5 15ALC05在我们的CPU基准测试中与配备相同处理器的联想IdeaPad 5 14ALC05。在单核基准测试中，它们以微弱的差距落后于测试领域。相比之下，Ryzen 5500U能够在多核基准测试中展示其性能，将配备英特尔酷睿i5-1135G7的对手大大甩在后面。

正如我们下面进一步的压力测试也显示，在Cinebench R15多耐力测试中，该CPU在最初的小幅下降后，随着时间的推移保持了非常稳定的处理速度，它只略微低于，联想ThinkPad L15 Gen 2，配备更强大的AMD Ryzen 5600U。

储存

东芝选择三星的512GB M.2固态硬盘显然对自己没有好处。该装置与14英寸机型中的存储设备不同，显然不如它以及对比机型中的所有其他SSD。然而，这只是在日常使用中，最多在传输特别大量的数据时才会明显。

图形卡

联想没有在IdeaPad 5 15ALC05中包括一个专门的图形解决方案，而是使用AMD Radeon RX Vega 7的图形性能。板载图形单元的最高工作频率为1,800 MHz；它配备了2 GB的图形内存，并支持DirectX 12。

当涉及到图形性能测试时，该测试设备排名在中场。然而，它的性能总是高于所有配备AMD Radeon RX Vega 7 的设备的平均水平，这意味着联想设法从GPU中获得了很多。此外，即使在负载下，GPU也能长期保持恒定的运行速度，尽管只有1300MHz左右。

当设备加载图形密集型计算时（如游戏），你甚至不需要在附近设置电源插座。毕竟，在电池供电的情况下运行3DMark 11时的总分是5080分，它的表现比插电时（5421分）差不到10%。

游戏性能

尽管联想IdeaPad 5 15ALC05绝对不是一款游戏笔记本电脑，但它至少可以用于偶尔的游戏环节。唯一的条件是，用户在图形质量方面不要期望太高。这是因为所提供的性能只有在选择最低，或根据游戏，甚至是中等或高的图形设置时，才足以实现流畅的游戏。

温度

当联想IdeaPad 5 15ALC05处于低负荷时，它的温度几乎没有超过室温。相比之下，它在负载下达到的温度略高于40°C（约104°F）。我们在顶部测量了最高的温度，位于显示器前面的中心位置。这不应该是一个惊喜，因为热空气被风扇通过铰链区域的通风槽输送到外面。

因此，笔记本电脑不仅在压力下保持相对凉爽，而且在任何情况下都可以正常操作，没有烫伤的危险。

联想IdeaPad 5 15ALC05在压力测试中出奇的放松。CPU的时钟频率稳定在3,400 MHz，GPU的时钟频率略低于1,300 MHz。温度在这种性能下保持不变，略高于75℃（约167°F）。没有发现任何节流现象，这意味着与最高性能相比几乎没有任何性能损失，即使硬件处于长时间的负载之下。在压力测试后立即运行3DMark 11基准测试时，与冷启动相比，笔记本电脑实现了相同的速率。

联想IdeaPad 5 15ALC05的内置立体声扬声器是一些最好的。诚然，像大多数其他笔记本电脑的扬声器一样，它们几乎没有任何低音，而且它们不会变得特别响。然而，它们以线性和相当平衡的方式再现了中音和高音。它们足以再现一些视频游戏的声音，流媒体电影，或在工作时听一些音乐。

能源管理。IdeaPad 5 15ALC05是节俭和持久的。

能源消耗

令人惊讶的是，联想IdeaPad 5 15ALC05实际上比几乎装备相同的14英寸模型消耗更少的电力。这表明，该面板的能源效率要高得多。与其他竞争者相比，该测试设备位居中场。它的最大消耗量为52瓦，这意味着65瓦的电源适配器是绝对足够的。此外，由于快速充电，电池可以迅速充电。

电池寿命

由于低消耗和非常大的70Wh电池，联想IdeaPad 5 15ALC05是一个真正的耐力跑者。它不能完全跟上LG Gram 14Z90P ，它是该级别的领导者。然而，在我们的比较中，它肯定足以击败竞争的15.6英寸设备。在Wi-Fi测试中，它的持续时间有时是竞争对手的两倍。即使是它较小的14英寸对应产品，也会提前3个小时耗尽能量。

联想IdeaPad 5 15ALC05在我们的测试中基本上令人信服。

该设备的得分，特别是它的大电池和长电池运行时间与低消耗相结合。CPU和GPU在测试中的表现正如人们所期望的那样，并且符合人们从稍小的14英寸姐妹机型中熟悉的情况，联想IdeaPad 5 14ALC05 。

但令人惊讶的是，15英寸机型在某些方面的得分明显比14英寸机型差。根据我们的测量，它的固态硬盘速度较慢，显示屏较差，读卡器也较弱。这有点令人惊讶，它减少了联想IdeaPad 5 15ALC05在我们测试中的良好印象。

单一的USB-C端口是不方便的，因为它被电源适配器占据。然而，上述对手无论如何都无法做得更好。否则，联想IdeaPad 5 15ALC05在测试中只显示了一些弱点，并证明它是一个用于办公、流媒体、浏览等方面的比较坚实的笔记本电脑。在图形要求不是特别高的情况下，甚至偶尔的游戏也可以玩。

简而言之：一个良好的全能型产品，具有很强的续航能力，价格合理，不需要害怕来自Acer Aspire 5 A515-56-511A和的竞争。 华硕VivoBook S15 D533UA.较小的 联想IdeaPad 5 14ALC05以及两款15.6英寸的笔记本电脑，分别是 联想ThinkPad L15第二代和 Honor MagicBook 15，在我们的测试中只获得了稍好的成绩。

价格和可用性

在撰写本文时，联想IdeaPad 5 15ALC05在美国似乎大多没有库存。尽管如此，你可以在Amazon或newegg，例如，看看该设备是否出现在那里。
