联想 ThinkPad L14 4 代英特尔评测:不再符合标准

16:9 恐龙

在测试 ThinkPad L 系列最新机型之前,我们先来回顾一下。联想 ThinkPad L14 Gen 4 英特尔版具有许多值得办公人员使用的特性,但与更多的现代竞争对手相比,它在一些重要的方面存在不足,屏幕就是一个重要的例子。
Business Intel Laptop / Notebook Raptor Lake Windows Thunderbolt

ThinkPad L 系列是联想商务笔记本电脑的入门级产品。价格更实惠的只有联想 ThinkPad E 系列,该系列缺少 WWAN 和智能卡读卡器等功能,因此更适合消费者或小型企业使用。ThinkPad L14 是 L 系列中最受欢迎的机型之一--今天,我们将评测配备英特尔 CPU 的联想 ThinkPad L14 Gen 4。我们已经对 AMD 版本的 联想 ThinkPad L14 G4此外,我们还将对后继型号 ThinkPad L14 G5 进行评测。

底盘与连接:众所周知的 ThinkPad L 塑料设计

该机箱与我们已经测试过的 联想 ThinkPad L14 第 4 代 AMD.从外观上看,笔记本电脑由灰色哑光塑料制成。屏幕和掌托表面涂有光滑的油漆,底部和显示屏边框则有粗糙的纹理--这种纹理并不十分讨人喜欢,但也能起到一定的作用。尽管 L ThinkPad 没有采用镁合金防滚架,因此比 T 系列更灵活一些,但我们对其稳定性并无太大不满。尤其是左下角可以稍微扭动一下。带金属盖的银色铰链能牢牢固定屏幕,但无法单手打开。最大打开角度为 180 度。

与 AMD 版的 ThinkPad L14 G4 相比,英特尔版的 L14 G4 增加了一个雷电 4 端口,而 Ryzen 版则没有。该机型的一大特色是配备了 microSD 读卡器,这是近期大多数 ThinkPad 笔记本电脑都没有的功能。读卡器的速度一般。Wi-Fi 解决方案有点受限,联想采用了老式的英特尔 AX201。它能完成任务,但只支持 Wi-Fi 6,不支持更现代的 Wi-Fi 6E 或 7 标准。

ThinkPad L14 Gen 4 的升级能力不错。ThinkPad 有两个 SO-DIMM 插槽,可容纳过时的 DDR4 标准模块。最大容量可达 64 GB。固态硬盘也是模块化的,但令人遗憾的是,联想使用了较小的 M.2 2242 尺寸。因此,最大容量受到了限制。一个 M.2 2242 插槽是开放的。在这里,可以放入可选的 WWAN 卡,相应的天线已经就位。非常值得称赞的是用户可更换键盘,这是目前大多数现代笔记本电脑所缺乏的。

输入设备:经济实惠的 ThinkPad,出色的键盘和鼠标替代品

我们评测设备的输入设备与 ThinkPad L14 Gen 4 AMD 完全相同。触摸板、键盘和典型的红色 ThinkPad TrackPoint 都非常出色,尤其是对于一款相当便宜的笔记本电脑而言。无论是书写长篇文字还是使用鼠标导航,联想 ThinkPad L14 G4 Intel 都能轻松胜任,使用起来非常舒适。

这种廉价面板的另一个弱点是色域覆盖率低。这种屏幕不适合处理色彩,也不适合用于多媒体,因为色彩也缺乏深度。

LED 背光也不是特别强,因此 ThinkPad L14 G4 不适合户外使用。

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
20.5 ms ... rise ↗ and fall ↘ combined↗ 11.4 ms rise
↘ 9.1 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. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
30.1 ms ... rise ↗ and fall ↘ combined↗ 14.2 ms rise
↘ 15.9 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. » 37 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 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 8746 (minimum: 5 - maximum: 343500) Hz was measured.

性能:办公室战士速度不快

联想提供了多种不同的处理器选择,它们都源自 Raptor Lake 处理器。与 T 系列不同的是,用户可以选择经济实惠的选项,如 英特尔 U300以及 i3 CPU。 英特尔酷睿 i7-1370P是最顶级的选择。有了 英特尔酷睿 3 100U,英特尔酷睿 1 系列 CPU 已进入 L14 G4,但该芯片也基于 Raptor Lake。

至于 GPU,选择就比较有限了,因为大部分都是同一英特尔 iGPU 的不同版本: 英特尔UHD Graphics, Iris Xe(80EUs) Iris Xe (96EUs)以及 英特尔图形酷睿 3 100U 的英特尔图形处理器都属于这一类。Nvidia 英伟达GeForce MX550是一种可选的专用图形处理器,但不在欧洲市场销售。

M.2 2242 SSD 最大存储容量为 2 TB。在内存方面,上限为 64 GB DDR4-3200,提供两个 SO-DIMM。

测试条件

通过 Windows 设置可以设置以下不同功率限制的性能模式(PL1 = 负载下的性能,PL2 = 短时间内的性能):

  • 最佳电池使用时间:PL1 10 W / PL2 20 W
  • 平衡:12.5 W / 35 W
  • 最佳性能:PL1 15 W / PL2 45 W

处理器

英特尔 英特尔酷睿 i5-1335U是一款拥有十个内核的处理器,其中两个 P 内核的时钟频率在 1.3 至 4.6 GHz 之间,八个 E 内核的时钟频率在 0.9 至 3.4 GHz 之间。作为 Raptor Lake U 芯片,英特尔计划将该芯片的 TDP 控制在 15 到 30 W 之间。 CPU 列表可用于详细的性能比较。

在低功耗限制下,联想 ThinkPad L14 Gen 4 的性能在预期范围内。它足以满足办公需求,但这款机型并不是性能冠军。搭载 AMD Ryzen 5 Pro 7530U 的 AMD 版 ThinkPad 在多核负载下速度更快,但在单核基准测试中表现不佳。

在电池模式下,联想限制了 CPU 的性能。在 Cinebench R23 多核测试中,ThinkPad 仅达到 6000 分,而不是 9000 分。

GPU

在 GPU 基准测试中,联想 ThinkPad L14 Gen 4 只能获得低于平均水平的性能分数,这并不奇怪。无论如何,这台笔记本电脑配备的 80 EU iGPU Iris Xe 并不是最快的 GPU,而且还受到单通道内存的限制。对于简单的办公任务来说,GPU 的速度已经足够快了。其他工作最好使用其他设备。对于长时间工作后的游戏,L14 G4 Intel 绝对不是一款合适的笔记本电脑。

排放与能源:ThinkPad L14 G4 大部分时间保持静音

噪音

ThinkPad 在空转或平均负载(配置文件:平衡)时保持安静。只有在压力测试期间的性能模式(配置文件:最佳性能)下,L14 G4 Intel 的风扇才会打开。即使在这种情况下,它的声音也不会特别大,只有 32 分贝(a)。

我们确实检测到了一些线圈啸叫。但几乎听不到,只有将耳朵贴在键盘上时才能听到。

压力测试(Prime95 + FurMark)

ThinkPad 笔记本电脑的性能并不出色。好的一面是,发热量得到了控制。最高温度为 45.5 摄氏度/114 华氏度,机箱温度并不高。

在 Prime95 和 FurMark 的压力测试中,我们没有发现任何节流现象。

联想 ThinkPad L14 Gen 4 的立体声扬声器面向用户,因为联想将其置于键盘上方。但它们的声音仍然太小,而且缺乏底座,因此外置扬声器和耳机很容易成为选择。

耗电量

对于像联想 ThinkPad L14 Gen 4 Intel 这样的办公系统来说,4.1 W 的最低功耗太高了。通常情况下,使用节能 CPU 且没有 dGPU 或高分辨率屏幕等功能的机型应该更加高效。

由于充电器的输出功率高达 65 W,68.3 W 的最大耗电量可能是个问题。不过,由于耗电量下降很快,在使用设备时电池应该不会放电。

由于耗电量大,联想 ThinkPad L14 G4 Intel 的电池续航时间低于平均水平并不令人感到意外。不过,令人失望的是,在 Wi-Fi 测试(150 cd/m²)中,联想的 57 Wh 电池的续航时间未能超过 8 小时。

结论:ThinkPad L14 G4 是一款可靠但过时的办公设备

联想 ThinkPad L14 Gen 4 是典型办公人员的可靠选择,但仅此而已。从很多方面都可以看出,无论是设计还是组件,这款系统都不是最新的硬件。

对我们来说,这与处理器的关系不大,而更多的是与屏幕等方面有关。16:9 的屏幕格式在笔记本电脑中已经过时,屏幕质量也低于平均水平。此外,电池续航时间令人失望,性能也没有什么特别之处。至少,输入设备非常好,连接选项也很不错,而且设备工作时没有很大的风扇噪音。

ThinkPad L14 G4 英特尔版在两个方面堪称猛禽:它使用的是 Raptor Lake,而且在屏幕格式方面是个 "恐龙"。硬件的过时确实给这款原本性能稳定的办公笔记本电脑带来了负面影响。

如果 ThinkPad L14 G4 英特尔版有较大折扣,那么这款设备可以成为一款可靠的办公笔记本电脑,尤其是对于学生而言。否则,最好还是换一款笔记本电脑--也许是配备 AMD CPU 的联想 ThinkPad L14 G5,我们将很快对其进行测试。惠普 HP ProBook 445 G10也是不错的选择。

定价和可用性

联想 ThinkPad L14 Gen 4 Intel 在德国的售价为 762 欧元。亚马逊在美国的售价为 1,200 美元
