联想 ThinkPad T14 G4 英特尔笔记本电脑评测：T 系列的 Raptor Lake 升级

Name: Lenovo ThinkPad T14 G4 21HD0043GE
Brand: Lenovo

猛禽联想ThinkPad T14的2023版本采用了英特尔猛禽湖系列CPU。与前代产品相比，新 CPU 的功耗似乎有所降低，但除此之外，联想 ThinkPad T14 4 代英特尔版的升级似乎并不大。

如果你想搜索 "典型的 ThinkPad"，ThinkPad T 系列一定是热门竞争产品。经典的设计，历经多代的缓慢更迭，联想并没有轻言尝试。像联想ThinkPad T14 Gen 4这样的笔记本电脑，都有一种务实、认真的气质。今天，我们测试的就是这款为办公环境而生的英特尔版 ThinkPad。

由于联想并没有对 ThinkPad T14 G4 的设计进行任何改动，因此我们跳过机身、连接和输入设备部分，直接从屏幕开始。关于笔记本电脑这些方面的全面介绍，请参阅我们对联想 ThinkPad T14 G3 的评测。

网络摄像头

联想 ThinkPad T14 Gen 4 的新功能是更高分辨率的网络摄像头，联想将这一规格提高到了 500 万像素。这使得图像更加清晰，但与前代产品的 1080p 网络摄像头相比，并无太大改进。

ColorChecker Lenovo ThinkPad T14 G4 21HD0043GE: 16.91 ∆E min: 1.73 - max: 33.77 ∆E

显示屏：哑光低功耗屏幕，反应时间慢

联想没有改变格式（16:10）或屏幕尺寸（对角线 14 英寸）。可用的屏幕选项（ThinkPad 的屏幕选项通常很多）也基本保持不变。与联想 ThinkPad T14 第 3 代联想取消了 WQUXGA（3,840 x 2,160）IPS 产品。取而代之的是，用户现在可以购买配备 2.8K (2,880 x 1,800) OLED 面板的联想 ThinkPad T14 4 代英特尔版。

我们的评测样本使用的可能是最受欢迎的一种，即 WUXGA 分辨率（1,920 x 1,200）的低功耗屏幕。联想销售的这款显示屏亮度值为 400 cd/m²。我们的测量结果显示，平均亮度为 369 cd/m²，低于承诺值。这意味着，在我们的比较中，T14 G4 英特尔显示屏落后于竞争对手--这并不一定完全正确，因为在屏幕质量方面存在一些差异。而联想总是使用几家不同的供应商；总是流行屏幕抽奖。

同样明显的是，屏幕的反应时间并不好。遗憾的是，这种低功耗液晶屏经常出现这种情况。EliteBook 845 G10 的 WQXGA 屏幕在这方面的表现要好得多。

根据卡尔曼的测量，出厂时屏幕的色调略微偏绿，我们使用 X-Rite i1Pro 2 色度计和 i1Profiler 进行校准后，色调得以纠正。校准后，Colorchecker deltaE 的平均值从 4.3 降至 1.6，差异非常明显。我们创建的色彩配置文件可随时免费下载。

屏幕几乎完全覆盖了小范围的 sRGB 色域，用户可以使用联想 ThinkPad T14 Gen 4 进行轻度照片编辑。

在室外使用时，联想 ThinkPad T14 Gen 4 由于采用了雾面屏幕，亮度值超过 300 cd/m²，因此足够实用。不过，ThinkPad 用户应避免阳光直射。

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
32.6 ms ... rise ↗ and fall ↘ combined	↗ 19.1 ms rise
32.6 ms ... rise ↗ and fall ↘ combined	↘ 13.5 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 87 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
48.3 ms ... rise ↗ and fall ↘ combined	↗ 20.7 ms rise
48.3 ms ... rise ↗ and fall ↘ combined	↘ 27.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 82 % of all devices are better. This means that the measured response time is worse 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 17853 (minimum: 5 - maximum: 3846000) Hz was measured.

性能：英特尔猛禽湖 U15 相当令人失望

联想 ThinkPad 以配置多样而著称。在 ThinkPad T14 Gen 4 Intel 上，联想让买家难以选择，因为有八种（！）CPU 可供选择：英特尔酷睿 i5-1335U, i5-1345U, i5-1340P, i5-1350P, i7-1355U, i7-1365U, i7-1360P和 i7-1370P.最大的区别是什么？后缀为 "P "的 CPU 拥有更多的性能内核和更高的功耗，其中 i7-1370P 是唯一拥有六个性能内核的 CPU。此外，还有 vPro 和非 vPro 之间的差异。

另一个区别：i7 型号包含 96 EU 的 Iris Xe，而 i5 型号则包含 80 EU 的 iGPU。此外，ThinkPad T14 Gen 4 英特尔版本还配备了英伟达GeForce MX550.

与 CPU 选择一样复杂的是内存的选择。ThinkPad T14 G4 有 DDR4-3200 和 DDR5-5200 两个版本。两者都有一些焊接内存，DDR4 型号为 8 GB，DDR5 配置为 16 GB。两种配置都有一个 SO-DIMM 插槽，因此内存最大容量分别为 40（DDR4）GB 和 48（DDR5）GB。但这只适用于 iGPU 机型，dGPU 机型有 16 或 32 GB 焊接式 LPDDR5X-6400 内存。

固态硬盘很好，很容易解释：只有一个 M.2 2280 插槽，通过 PCIe 4.0 连接。

测试条件

联想使用 Windows 设置来控制能耗配置文件和 CPU 速度。有三种配置文件可以调节处理器的功率限制，从而调节其功耗和速度。功耗限制 1 可以长期使用，而功耗限制 2 则适用于短期性能任务：

最佳电池寿命：PL1 11 瓦/PL2 11 瓦
平衡：PL1 14 瓦 / PL2 20 瓦
最佳性能：PL1 22.5 瓦 / PL2 50 瓦

处理器

使用英特尔酷睿 i5-1335U，我们对联想 ThinkPad T14 Gen 4 的基本型号进行了评测。这颗 Raptor Lake i5 芯片属于 U15 系列，由 2 个性能核心和 8 个效率核心组成，设计 TDP 为 15 W。在上一代英特尔 CPU 中，CPU 的功耗远高于标称 TDP。最高时钟频率达到 4.6（P 核心）和 3.4 GHz（E 核心）。通过超线程技术，CPU 拥有 12 个线程。如需更详细的比较，请参阅我们的 CPU 比较列表。

联想 ThinkPad T14 Gen 4 英特尔版的 CPU 性能总体上令人失望。所有竞争对手都有更好的表现。诚然，与 AMD 相比，英特尔处理器在单核性能方面具有优势，但当使用所有内核时，英特尔 ThinkPad 就被甩在了后面，英特尔 ThinkPad T14 Gen 3 处理器的单核性能仅次于 AMD。ThinkPad T14 Gen 3 英特尔也更快。值得一提的是，旧型号使用的是 P28 CPU，它多了两个 CPU 内核。此外，我们主要将性能低于平均水平的原因归咎于英特尔，因为 T14 Gen 4 的 PL2 为 22.5 W，其功耗仍高于该 CPU 标称的 15 W TDP - 近期的英特尔 CPU 非常耗电，在超极本设计中没有太大意义。

在电池模式下，我们没有发现 CPU 性能有任何限制。

GPU

对于英特尔来说，自 2021 年以来在 iGPU 领域一直没有太大的动静，Tiger Lake 。联想 ThinkPad T14 G4 英特尔版配备了相同的Iris Xe w/80 EUs我们已在许多其他Tiger Lake 、Alder Lake 和 Raptor Lake 笔记本电脑上测试过这款 i5 处理器。

作为一个集成的 GPU，它没有自己的内存，而是依赖于主系统内存--因为它始终在双通道模式下运行，所以尽管有空闲的 SO DIMM 插槽，性能也不会受到限制。GPU 仍无法胜任最简单的任务，游戏性能也几乎不值一提。不过，对于一款面向商务用户的笔记本电脑来说，这一点并不重要。

能源管理：ThinkPad T14 G4 的电池续航能力不错

耗电量

联想ThinkPad T14 G4的功耗出乎我们的意料--出乎意料的低，因为与ThinkPad T14 G3 AMD版相比，它的功耗更低。就 2022 年的 ThinkPad 而言，AMD 版本的效率更高。另一方面，惠普笔记本电脑和戴尔笔记本电脑的功耗较高也不足为奇，因为两者的屏幕分辨率都较高。

67.2 W 是负载下的最大功耗，高于 65 W 充电器的容量。由于负载下的功耗会迅速降低，电池应该不会因此而放电。

电池寿命

结论：ThinkPad T14 Gen 4 英特尔版是一款非常适合商务用户的设备

当该机型最大的新闻是令人困惑的内存选择时，情况就很清楚了：从 ThinkPad T14 G3 Intel 到 ThinkPad T14 G4 Intel 的更新并没有达到震惊世界的程度。在 "新功能 "列表中，我们可以看到英特尔 Raptor Lake 的预期更新，以及新的内存选项（Nvidia 型号为 DDR5 或 LPDDR5X）和新的 500 万像素网络摄像头。此外，还有一个新的可选 OLED 屏幕，但我们没有在此进行测试。

总而言之，联想 ThinkPad T14 Gen 4 英特尔版的配置与前代相同。由于前代产品已经是一款非常出色的商务笔记本电脑，因此这并不意味着消极的含义。低功耗的雾面显示屏、丰富的端口选择、出色的输入设备、超长的电池续航时间、低温和噪音排放，所有这些都集成在一个坚固耐用且移动性良好的机箱中，使 ThinkPad 笔记本电脑成为一款出色的商务笔记本电脑。用户可更换键盘也是笔记本电脑中不多见的功能，可升级的 WWAN 插槽也值得赞赏。

比较遗憾的是性能，但这只是联想的部分原因，更多的是英特尔当前 CPU 的问题。不过，如果联想能像惠普目前的许多 EliteBook 笔记本电脑一样，在 ThinkPads 上少焊一些元件并安装两个内存插槽，那就更好了。这款笔记本电脑的另一个问题是屏幕速度太慢。

可靠：如果需要一款可靠的办公笔记本电脑，联想 ThinkPad T14 Gen 4 Intel 是一个不错的选择。不过，性能并不是这款机型的强项。

与惠普 EliteBook 845 G10，联想ThinkPad T14 Gen 4有了一个强劲的竞争对手，其CPU性能完全不在一个水平线上--尽管测试的版本为此牺牲了电池续航时间。英特尔的 T14 G4 也受到了 AMD 自身机型 T14 G4 AMD with Ryzen 7040U 的内部竞争。该机型现在还配备了 USB4 接口，抢走了英特尔机型的优势。我们非常期待测试 AMD 型号。
