联想IdeaPad Flex 5可转换审查。小型i3-1215U的强大入口

高效的灵活性。

IdeaPad Flex设备简单,但有一些亮点,如Thunderbolt、键盘照明,当然还有触摸屏,它结合了办公笔记本电脑和14英寸平板电脑。相当实惠的第12代i3以其沉默给人留下深刻印象,但也有令人惊讶的速度。
Alder Lake Convertible / 2-in-1 Laptop / Notebook Touchscreen Windows Thunderbolt

联想IdeaPad Flex 5 14IAU7是一个相对高效的可转换产品,它希望成为消费领域任何场合的笔记本电脑。其性能和设备对于办公用笔记本电脑来说处于一个较高的水平。当你把它作为平板电脑放在腿上时,它保持了相对安静和凉爽。在14英寸,它的尺寸不再是绝对的移动,而是为流媒体、冲浪和工作提供了一个舒适的大屏幕区域。

有了 联想IdeaPad Flex 5i 14IAU7我们已经测试了一个更强大的版本,现在入门级版本具有最小的配置和相应的最低价格近700欧元(约737美元),必须在这个测试中证明自己。 小型i3-1215U使用一个瘦身的图形单元,计算单元较少,仅由8GB的内存支持。

一个竞争对手是例如明显更薄的 三星Galaxy Book Pro 360 13,以及 华硕Vivobook Flip 14Acer Spin 3 SP314也提供了类似的结构和相当的计算性能。

案例和设备 - 坚固的IdeaFlex没有任何缝隙

金属显示盖立即确保了高质量和相当坚固的印象。IdeaPad Flex也证实了这一点,它的重量相对较高,为1.6公斤(约3.5磅),使其成为较重的可转换设备之一。底座是由塑料制成的,似乎是准确地组装起来的。翘曲的尝试只导致了有限的成功,这可能与高重量有关。

显示器的铰链调整得很好。你可以用一只手打开盖子,直到60度的角度。在那之后,就很难再打开了,以防止触摸显示器时出现一些恼人的晃动。

两个USB-A和一个Thunderbolt 4端口肯定足够用于连接外围设备。有了HDMI、SD读卡器和用于耳机的音频端口,一些额外的有用连接也可以使用。尽管你可以通过Thunderbolt端口为可折叠机充电,但这并不是你唯一的充电选择,该端口通常可以保留用于其他用途。在路上,你仍然可以用标准充电器或合适的电源为笔记本电脑充电。

WLAN的速度略低于平均水平,但近1000兆比特/秒的速度仍在电缆连接的范围内。具有全高清分辨率的网络摄像头即使在光线不好的情况下也能提供令人信服的图像质量。虽然相应的麦克风可以听起来更好一点,但它仍然可以清晰地记录你的声音,即使在较远的距离也能可靠地记录。

可以更换固态硬盘、WLAN模块和电池。

输入设备 - 带有良好的键盘的可转换设备

联想IdeaPad Flex的键盘接近于标准尺寸,这确保了打字的成功率,而不需要适应它或需要任何调整。虽然近1毫米的行程并不令人印象深刻。然而,各个按键的阻力可以说是调整得很好。即使是较长的打字任务也会变得很舒适,即使该键盘不能与大多数商务笔记本电脑的键盘竞争。但至少有一个键盘照明。

触摸板为12 x 7厘米(约4.7 x 2.8英寸),尺寸舒适。光滑的表面允许指尖准确滑动。只有底部区域的隐藏键可以变得更清晰一点。

剩下的是最重要的输入法:16:10格式的大触摸屏使你可以毫不费力地控制IdeaPad。通常的命令,甚至是用几个手指的命令,都能准确地成功。特别是使用屏幕键盘的书写很有趣,因为按键的大小与物理键盘接近。

除了略高于全高清的非常合适的分辨率之外,该显示器并不十分令人印象深刻。亮度只是勉强能够满足最低要求,平均仅有290cd/m²。对比度值仍然不错,尽管它倾向于在较低的范围内,约为1,100:1。

尽管它整体上相当弱,但该分辨率仍然使显示器在冲浪、办公任务,甚至视频流方面工作得很好。

我们没有注意到在低亮度下屏幕的任何闪烁。也只有极少的屏幕出血,考虑到相当弱的背景照明,这也不是很令人惊讶。

颜色没有得到最佳的再现。在DeltaE高于6的情况下,我们测量的偏差显然是在可见的范围内。但至少没有明显的色差。照片往往显得略微苍白和灰暗,但如果你不直接看它们的对比,这就变得不那么引人注目了。

色彩空间的覆盖率也处于较低水平。许多中档笔记本电脑使用的sRGB色彩空间只显示到64%。在看高清晰度的数码照片时,这将变得很明显。这也使得该显示器几乎不适合图像处理。然而,这些数值对于娱乐目的来说还是可以的。

Display Response Times

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
20 ms ... rise ↗ and fall ↘ combined↗ 11 ms rise
↘ 9 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. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (20.8 ms).
       Response Time 50% Grey to 80% Grey
30 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 16 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 36 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 8580 (minimum: 5 - maximum: 343500) Hz was measured.

由于最大亮度较低,且表面反光,在户外不会有太多东西可看。此外,在电池运行时,最大亮度更低。但至少在阴暗的地方,你仍然可以轻松地阅读文本。

性能--具有高效计算核心的可转换装置

有三种处理器可供选择,其中包括英特尔酷睿i3-1215U, i5-1235U,或i7-1255U,联想IdeaPad Flex 5 14IAU7提供高效和节俭的计算核心,而且还涵盖了大带宽。目前最快的型号价格为1000欧元(约1053美元)。

我们的测试设备,也就是配备最小的处理器、小型固态硬盘和仅有少量内存的敞篷车,价格约为700欧元(约737美元)。即使设备简陋,这仍然比绝对的入门级产品高出不少。然而,程序的快速启动、始终流畅的视频再现和多媒体应该不会对硬件造成任何问题。另一方面,多任务处理将相当快地显示出其性能的极限。

测试条件

预装的 "Lenovo Vantage "软件,不幸的是包括许多错别字和不幸的翻译,提供三个性能级别。极限性能、智能冷却和节省电池模式。

我们所有的测试都是在极限性能模式下运行的,这也是默认模式。然而,这些设置对CPU的功率限制没有影响。

处理器

这款英特尔酷睿i3-1215U在我们的IdeaPad测试单元中,有两个性能和六个效率核心,属于Alder Lake系列中最小的型号。然而,这也意味着它仍然明显领先于入门级的CPU,如 Intel Celeron 7300奔腾8500同一代处理器。

除其他外,它支持10个线程,这在我们的Cinebench R15恒定负载测试中得到了反映。例如,它仍然比上一代的i5-1135G7平均高出约10%,尽管那确实是一个更高级别的处理器,可以在许多小型商务笔记本电脑中找到。

对于一个移动的i3处理器来说,其结果肯定是令人印象深刻的。计算性能对于几乎所有与工作无关的任务来说应该是完全足够的。当你同时运行两个不同的程序时,情况也是如此。

系统性能

凭借其有限的硬件,联想IdeaFlex获得的评价与我们测试的所有转换机的平均值相差不大。它甚至能够大大超过一个非常简单的模型,如 Acer Spin 3 SP314.

在打开新程序、冲浪或并行运行程序时,系统的反应很快。另一方面,安装过程需要更多的时间,比如说。此外,太多打开的程序或众多的浏览器标签会完全填满有限的工作内存,这大大限制了速度。

存储解决方案

由于有了放置器,M.2固态硬盘可以被标准2280格式的模型所取代。
由于有了放置器,M.2固态硬盘可以被标准2280格式的模型所取代。

如果没有更多的照片收藏,所提供的256GB,几乎有200GB,应该足以满足所有的程序和个人数据。尽管2242格式的短固态硬盘是通过PCIe 4.0连接的,但它只达到了PCIe 3.0的速度。在恒定负载测试中,由于电路板的升温,传输率下降,尽管它被一层厚厚的热浆覆盖。

然而,这不会造成限制性影响。IdeaFlex的性能不足以充分利用固态访问率。此外,竞争对手的速度也只是很少的。

图形卡

英特尔UHD Graphics 64EUsiGPU不允许流畅地执行复杂的图形任务。与办公用的笔记本电脑相比,其性能几乎没有达到平均水平。即使是配备英特尔酷睿Tiger Lake 和英特尔Iris Xe 80EUs的旧笔记本电脑也有优势。在这里有一个优势。

对于个人用途的图像甚至视频处理来说,其性能是足够的,即使你有时仍然需要等待一下。要求不高的老游戏也可以顺利进行。例如,2018年的《奇异旅团》在最低设置下达到明显超过60帧。图形性能也保持绝对稳定(尽管是在低水平),正如我们的TheWitcher 3 恒定负载测试显示的那样。

系统噪音

无论铰链的开启角度如何,风扇的通风口几乎没有被遮挡。
无论铰链的开启角度如何,风扇的通风口几乎没有被遮挡。

对于要求不高的任务,联想IdeaFlex不会产生任何噪音。在同时播放视频时打开几个标签会导致风扇启动,但它很少变得令人讨厌。大多数时候,风扇保持沉默或只有极少的声音。

仅仅在最大负荷下,我们测量到42分贝,这比竞争对手略高。然而,这将是一个例外。

温度

怠速运行时和低负荷下缺乏风扇噪音也带来了一些明显的升温,尽管最高35℃(95°F)的温度仍然可以接受。在冲浪或流媒体视频时,将其放在腿上或其他柔软的表面上使用似乎是现实的。

另一方面,当有高要求的任务时,我们会建议将其安全地放在桌子上。在近48°C(118°F)的温度下--但只是在压力测试中--它比大多数竞争对手的温度更高。

IdeadPad Flex在低音和中低音方面没有很好的处理,但高音和声音听起来很好。 这使得该款可转换产品只在有限的意义上适合听音乐。不过,作为笔记本电脑的扬声器,它们仍然做得很好。

电池寿命

我们的网上冲浪测试也显示了该处理器的效率。10小时的大关只是勉强错过,而更强大的 联想Yoga Slim 7i而性能更强的联想Yoga Slim 7i的电池容量更大,例如,它几乎提前一小时停止。非常相似的 联想IdeaPad Flex 5i我们还测试了非常相似的联想IdeaPad Flex 5i,它的CPU速度更快,几乎处于同一水平。

评语 - 一辆速度不快但装备非常好的敞篷车

IdeaPad Flex 5几乎通过银行让人印象深刻。相对较小的处理器为几乎每项任务提供足够的性能,同时仍然保持高效。在负载情况下,这让底部稍微变得太热,虽然。

所有重要的连接,包括HDMI和SD卡插槽都可用。Thunderbolt端口也允许你轻松地连接外部固态硬盘或底座。

操作也很好,键盘和触摸板提供了良好的质量。我们特别喜欢在冲浪时将触摸屏与Windows 11的平板电脑模式相结合。

联想IdeaPad Flex 5 14IAU7良好的工作速度、有用的连接和舒适的操作确保了它的高度灵活性。

我们还徒劳地寻找其他方面的弱点。与双阵列麦克风一起,网络摄像头非常适用于视频通话。虽然小型扬声器的音质当然可以更好,但对于笔记本电脑或可转换的产品来说,它是可以的。

只有显示屏让人觉得没什么激情。亮度和色彩强度都处于较低水平。但这几乎不会成为一个障碍,因为无论如何IdeaPad不是为图像处理或HDR视频而设计。相反,它以其良好的分辨率提供了细节丰富的图像。

有限的存储空间和工作内存也应该足以满足个人使用。那些想用它来冲浪、流媒体、或完成简单的办公任务或玩小型游戏的人不会过度消耗硬件。

另一方面,如果事情需要明显加快,否则几乎相同的 联想IdeaPad Flex 5i配备i5-1235和更多的内存将是一个不错的选择。但如果你主要需要用平板电脑看视频和冲浪,那么更简单的Acer Apin 3 SP314-21N-R4GU可能也足够了。

价格和可用性

英特尔版本的联想IdeaPad Flex 5可直接从联想,起价765美元。.然而,虽然规格列出了三种不同的英特尔处理器,但目前似乎只有i7型号在美国有售。采用第11代处理器的更简单的i3版本可从亚马逊购买,价格为338美元。.
