联想ThinkPad P14s G2 AMD笔记本电脑评论。拥有哑光4K液晶显示器和Ryzen 5000
到目前为止，联想ThinkPad P系列一直是英特尔处理器的一个堡垒。不过有一个例外。14英寸的联想ThinkPad P14s是联想工作站中的移动入门级机型，从去年开始也有采用AMD Ryzen CPU的版本。虽然去年联想工作站笔记本电脑使用了AMD Ryzen Pro 4000，但随着ThinkPad P14s G2的推出，AMD Ryzen Pro 5000自然也随之而来。
该ThinkPad P14s AMD前辈已经提供了出色的CPU性能，但它缺乏一个专用的GPU。这种不寻常的缺乏也涉及到较新的模型，因此，看看它在与更多采用英特尔CPU和Nvidia GPU的传统工作站的比较中表现如何，将是很有趣的。
由于联想没有在机箱上做任何改变，我们请你参考我们对联想ThinkPad T490的评论，以了解有关设计、设备和输入设备的信息。

ThinkPad笔记本电脑中的哑光UHD显示屏
对于使用与前代机型相同设计的笔记本电脑来说，其他方面的变化必须为购买提供论据。显示器就是这样一个领域。然而，在联想ThinkPad P14s G2 AMD中，大多数LCD选项仍然与上一代产品相同。 联想ThinkPad P14s G1前代机型，而且不幸的是，14英寸液晶显示器的16:9格式也没有改变。
新的变化是，基于AMD的机型首次也提供了4K超高清显示屏（3840 x 2160像素），这在去年还是保留给英特尔ThinkPad的。此外，UHD液晶显示器以前是光面的，但现在是哑光的。虽然我们能够测试新的、无光泽的UHD液晶显示器，以及全高清分辨率（1920 x 1080像素）的低功耗液晶显示器，但本评论的重点是带有4K UHD液晶显示器的型号。
UHD显示屏的亮度应该达到500cd/m²，这确实是最高值的情况。最高值确实是512 cd/m²，但联想笔记本电脑的平均亮度 "只有 "486 cd/m²。这使得它比能够在ThinkPad X1 Carbon Gen 8 中测试的光面UHD LCD略微暗一些。但与此相反，这里没有使用脉冲宽度调制（PWM）进行亮度控制。而与低功耗的FHD LCD相比，另一个突出的优势是UHD屏幕的响应时间明显更好。

尽管ThinkPad笔记本电脑在交付状态下应该已经被校准，但我们用X-Rite i1 Pro 2色度计和Calman进行的测量显示出一种红色色调。我们使用X-Rite i1Profiler进行的校准消除了这种色调。创建的色彩配置文件可供您免费下载（见上文 "下载ICC文件 "链接）。校准后，显示效果非常好，内容显示非常清晰，色彩鲜艳，这也是由于对比度值好。
不仅完全覆盖了sRGB色彩空间，而且宽泛的DCI-P3色彩空间也几乎完全覆盖，达到96.8%。这意味着我们绝对可以想象使用联想ThinkPad P14s G2的超高清液晶显示器进行图像处理。
哑光表面是在户外使用笔记本电脑的一个巨大改进。你不必担心恼人的反射，而且高亮度使在户外工作时非常舒适。然而，阳光直射仍然造成一些困难。

视角的稳定性？由于几乎所有的笔记本电脑都使用了IPS显示屏，这几乎不再是一个问题，联想ThinkPad P14s第二代AMD在这方面也表现得非常出色。
CPU性能。Ryzen 5000提高了联想笔记本电脑的单核性能
在联想ThinkPad P14s G2 AMD中，你可以在AMD的两款Ryzen Pro CPU中进行选择，分别是AMD Ryzen 5 Pro 5650U和AMD Ryzen 7 Pro 5850U.与其他工作站相比，P14s AMD没有配备专用GPU。这意味着，集成的AMD图形芯片必须完成这项工作。一块M.2-2280固态硬盘也完成了存储解决方案的工作。在内存方面，最大是48GB的DDR4-3200，其中16GB是焊接在一起的。单个SO-DIMM插槽最多能够接受32GB的模块。
处理器
实验结果AMD Ryzen 7 Pro 5850U是一个具有八个核心和十六个线程的处理器，基于Zen 3架构和Cezanne U系列。作为U系列的CPU，典型的TDP为15瓦，时钟频率在1.9和4.4GHz之间。你可以将该处理器与当前其他CPU进行比较，在我们的 CPU列表.
由于我们测试的是 ThinkPad P14s G1与 Ryzen 7 Pro 4750U，它是5850U处理器的直接前身，你可以很容易地看到Ryzen 5000与Ryzen 4000相比的优势。较新的联想ThinkPad P14s第二代AMD在多核基准测试中快10%左右。在单核测试中的优势甚至更大，5850U平均比前代机型快17%。另一个有趣的比较是与 P14s G2英特尔和ZBook Firefly 14 G8使用i7-1165G7。英特尔的CPU在几个核心的负载下明显较慢。他们只在单核性能上有一些部分优势。
在电池运行情况下，3DMark 11物理测试中的CPU性能会降低约28%。

ǞǞǞ AMD Radeon RX Vega 8作为单一的GPU。GPU-Z称其为 "AMD Radeon Pro Graphics"，这表明ThinkPad P14s第二代中使用了特殊的工作站驱动程序。
有了经过认证的驱动程序，使用CAD解决方案的客户，例如，将知道他们的软件可以在ThinkPad笔记本电脑上运行。然而，纯粹的性能和预期的一样弱。作为一个带有集成图形芯片的入门级工作站，没有自己的专用存储，其性能能力还不到工作站平均水平的一半。但至少性能比前代产品略好。另一方面， ThinkPad P14s英特尔和 ZBook Firefly 14 G8都以其专用GPU (Nvidia T500).
如果你用电池电源运行联想ThinkPad P14s G2 AMD，在3DMark 11 GPU测试中的GPU性能下降了约33%。

噪声排放
当联想ThinkPad P14s AMD G2在空闲状态下运行时，无论选择何种性能模式，风扇都保持关闭。因此，它在日常冲浪和办公操作中也会保持安静。负载下的噪音水平会发生变化，但在我们用3DMark 06进行的中位测试中，风扇仍然非常安静地运行。28.19 dB(A)几乎听不到了。在压力测试的几分钟后，噪音水平增加到40.77 dB(A)，这是很明显的。然而，主动冷却从来没有变得令人讨厌的噪音。
如果你把耳朵贴在键盘上，你可以听到安静的嘶嘶声，但在与笔记本的正常工作距离内，你将无法再听到这种噪音。

温度
在空闲运行期间，联想ThinkPad P14s第二代AMD几乎保持完全冷却。在Prime95和FurMark的压力测试中，机箱的升温相对均匀。底部的热点达到47.5 ºC（117.5ºF），顶部达到42.8ºC（109ºF）。这没有理由让人担心。不幸的是，掌托也明显升温，这可能导致一些手汗，特别是在夏天。
在压力测试中，CPU在开始时能够全速运行，但过了一会儿就会改变。在长达一小时的测试接近尾声时，联想笔记本电脑中的AMD处理器被限制在11瓦左右，这对于1.4GHz的时钟速度来说仍然足够。就在压力测试之后，ThinkPad达到了明显较低的3DMark 11成绩，只有5057分（-20%），因此CPU和iGPU都受到了节流的影响。
(±) The maximum temperature on the upper side is 42.8 °C / 109 F, compared to the average of 38.2 °C / 101 F, ranging from 22.2 to 69.8 °C for the class Workstation.

发言人
联想ThinkPad P14s AMD G2的立体声扬声器位于键盘和屏幕之间，将声音投射到用户身上。它们的音量是可以接受的，即使是缺乏低音频率的声音。因此，声音不是音乐的理想选择，但联想笔记本电脑的扬声器足以用于视频会议。
对于其他一切，建议使用可通过蓝牙或工作无误的3.5毫米音频端口连接的外部解决方案。

消耗功率
由于我们也能够测试P14s G2 AMD与全高清低功耗液晶显示器几乎相同的配置，我们可以很容易地记录4K UHD显示器带来的更高功耗。在空闲运行期间，差异约为10%至24%，而低功耗显示器主要在最大亮度下具有优势。这意味着，这种配置提供了一个优势，特别是在户外使用时，因为你可以在最大亮度下运行更长时间。
在最大负荷下，与配备Nvidia GPU的英特尔型号相比，缺乏专用GPU导致联想ThinkPad P14s G2 AMD的消耗量更低。电源的性能为65瓦，没有完全使用到极限。

电池寿命
电池寿命仍然是联想ThinkPad P14s AMD前代产品的一个不好的弱点，我们曾将其主要归因于PrivacyGuard显示屏。幸运的是，联想从联想ThinkPad P14s G2 AMD的50瓦时电池中获得了明显更多的电池寿命。即使是4K UHD液晶显示器，它在150cd/m²显示亮度的Wi-Fi测试中仍然达到了8小时以上。采用全高清省电显示屏的配置持续了约10小时。对于4K液晶显示器，你只需记住，如果你将显示器亮度设置到最大水平，电池寿命就会明显变差。在这些条件下，在Wi-Fi测试中，电池只能勉强维持6小时。

结论：ThinkPad P14s G2 AMD弥补了G1的弱点
我们已经评估了 第一代联想ThinkPad P14s AMD值得推荐，尽管它的PrivacyGuard显示屏不是很有吸引力，而且测试配置的电池寿命很低。因此，采用AMD Ryzen 5000的较新的联想ThinkPad P14s第二代也将获得推荐，这并不奇怪，因为电池寿命明显更好，而且新的ThinkPad笔记本电脑可以配置出色的哑光4K UHD显示屏。这个选项在前代产品中还没有。
有了这个，最糟糕的弱点得到了弥补，这使得联想ThinkPad P14s G2 AMD成为非常好的入门级工作站。它是一个非常好的选择，特别是对于那些注重CPU性能的应用。另一方面，在与其他工作站的比较中，GPU性能是一个弱点，就像缺乏Thunderbolt一样。此外，P14s没有提供全尺寸的SD读卡器，Realtek Wi-Fi卡是有限制的，如果它采用16:10格式，对目标群体来说会更好。
联想ThinkPad中的高分辨率显示屏和AMD Ryzen--联想ThinkPad P14s G2 AMD的确是第一款提供非常好的4K UHD显示屏的Ryzen ThinkPad。
虽然这代表了与一些较新的ThinkPad设计相比的劣势，如 联想ThinkPad X1 Carbon G9，具有1.8毫米键程的 "老 "键盘是这款ThinkPad笔记本电脑的重要优势之一。与惠普的 ZBook Firefly 14 G8，ThinkPad P14s G2 AMD提供了更好的CPU性能和工作内存的可扩展性作为重要优势，但ZBook提供的图形性能反而略高。
价格和可用性
联想目前提供各种配置的联想ThinkPad P14s G2 AMD，起价1136美元。在美国。然而，目前所有可用的配置似乎都使用了各种全高清显示屏版本，尽管页面上注明了显示屏 "高达14英寸4K UHD"。另一方面，亚马逊提供英特尔配置的4K UHD显示屏，起价2315美元.
