联想ThinkPad P1 G4笔记本电脑--工作站版的X1 Extreme G4评测
ThinkPad X1 Extreme是联想几年来的多媒体旗舰笔记本，主要与戴尔XPS 15竞争。ThinkPad P1是工作站的对应产品，第四代产品得到了重大更新，因为联想现在使用16英寸显示屏，长宽比为16：10。除了英特尔的新Tiger Lake-H45处理器（包括至强），你还可以得到Nvidia的新专业GPU。
联想为ThinkPad P1 G4提供了两种基本型号（也适用于X1 Extreme G4），因为根据显卡的不同，你要么得到一个传统的冷却解决方案（与Nvidia T1200&RTX A2000在P1 G4中或RTX 3050 TiX1 Extreme G4中的Nvidia T1200和RTX A2000或RTX 3050 Ti），或结合更强大的显卡使用蒸汽室冷却。不过这种冷却方案需要更多空间，所以只有一个M.2-2280插槽，而且不能配备WWAN模块。
我们的ThinkPad P1 G4的测试单元是一个入门级的模型，代号为20Y30017GE，售价约为2400欧元，配备了新的16英寸显示屏和WQHD分辨率（2560 x 1600像素），配备了酷睿i7-11800H，新的Nvidia T1200 GPU），以及存储容量为512GB的快速PCIe 4.0 SSD。更多ThinkPad评论。

外壳 - 仍然是典型的ThinkPad
从机箱上看，你很难将新的ThinkPad P1 G4与它的前任区分开来。 前辈.然而，当你打开盖子时，你会立即注意到新的16:10屏幕，边框更窄，键盘旁边还有新的扬声器栅栏。新的电源按钮，也包括指纹扫描仪，稍微向上移动。
材料基本相同，你仍然得到光滑的塑料表面，下面是金属或混合材料。你可以很快看到指纹，与其他ThinkPads类似，我们预计会有油腻的地方。稳定性仍然很好，无论是底座，还是盖子都不能明显的扭曲或凹陷，也没有吱吱嘎嘎的声音。与以前的ThinkPad型号一样，P1 G4符合MIL-STD-810H要求，但联想没有列出个别测试。
两个铰链允许最大打开角度为180度，并且调整得很好，因为几乎没有任何弹跳。不过，在25度或更低的角度，盖子会自动关闭。在实践中，你几乎不会使用这个屏幕位置，所以这不是一个破坏性因素。配备4K触摸屏的机型再次获得了不同的盖子设计，带有碳纤维图案（印刷）。
与之前的笔记本P1，第四代略微更窄、更薄，但也反过来更深了一些。因此，更大的16英寸屏幕并没有真正影响整个机箱的尺寸。在对比组中，新的P1 G4是最大的设备之一，但也是最轻的设备之一，只有1.8公斤。
连接性 - 带有雷电4的ThinkPad
ThinkPad P1 G4的端口情况非常好。除了两个现代的USB-C端口，包括Thunderbolt 4，你还可以得到两个普通的USB-A端口，甚至一个全尺寸的SD卡读卡器。电源是通过熟悉的SlimTip连接器提供的，但你也可以通过USB-C给电池充电。然而，65瓦的标准ThinkPad适配器不起作用，我们不得不使用至少90瓦的设备。配备T1200 GPU的机型获得了HDMI 2.0输出（4K @60 Hz），而更强大的RTX GPU获得了HDMI 2.1（最大8K @60 Hz）。联想不再为新P1提供智能卡阅读器。

全尺寸的SD卡读卡器仍然包括在内，我们确定，结合我们的UHS-II参考卡（AV Pro V60），传输速度非常快，超过200 MB/s。

通信 - Wi-Fi 6E和蓝牙5.2
ThinkPad P1 G4配备了英特尔的最新Wi-Fi模块AX210。它支持新的Wi-Fi 6E标准以及蓝牙5.2。在我们与路由器Netgear Nighthawk RAX120进行的标准化Wi-Fi测试中，传输速率约为1.4Gbps，在实际测试中，我们也没有发现信号质量或范围有任何问题。没有以太网端口，所以如果你想使用有线网络，你必须使用相应的USB-C适配器。
你可以为ThinkPad P1 G4配置高通公司的5G模块（Snapdragon X55），但之后不能安装，因为没有包括必要的天线（不适合WWAN）。
网络摄像头 - ThinkPad，带1080p传感器
ThinkPad P1 G4是少数配备1080p网络摄像头（包括机械快门）的现代ThinkPads之一。与通常的720p传感器相比，分辨率和图片质量都略胜一筹，但我们仍然建议使用智能手机来拍摄好照片。还有一个额外的红外摄像头，用于通过Windows Hello进行面部识别。
维护
你只需要松开八颗标准的飞利浦螺丝，就可以拆下底盖，并把它抬起来。每个版本的P1 G4都有两个SODIMM插槽（DDR4-3200，最大64GB）和一个M.2-2280插槽，用于快速PCIe 4.0 SSD。我们配备T1200 GPU的设备（也适用于RTX A2000 GPU）提供一个额外的M.2-2280插槽（PCIe 3.0 x4）。你可以清洁风扇和更换电池（用螺丝固定），但所有其他组件，包括Wi-Fi模块都焊接在主板上。
输入设备--像X1 Carbon G9那样减少了按键行程
键盘
下一个大的变化是键盘，因为联想基本上使用了我们所知道的同样的装置，即从X1 Carbon G9，但它稍微宽一点，因为所有的键（也在右侧）都有相同的尺寸。联想将按键行程从之前的1.8毫米减少到1.5毫米。P1 G3/X1 Extreme G3而且还使用了更扁平的按键。与老款ThinkPad相比X1 Carbon G7/G8相比，后者也使用1.5毫米的键程，这导致打字体验略差。与目前的X1 Carbon G9相比，P1 G4的主观体验略好，这要归功于更坚固的底座。总而言之，它仍然是一个好的键盘，但与以前的型号相比更差，与戴尔或惠普等对手相比已经没有优势。有一个两段式的白色照明，适合较暗的环境。
触摸板和TrackPoint
ClickPad（11.5 x 6.9厘米）提供了良好的滑行能力，并支持微软的Precision 标准，因此包括手势在内的标准操作效果良好。点击机制也给人留下了良好和高质量的印象，点击的声音很闷。与旧的ThinkPad P1，TrackPoint键与X1 Carbon没有相似之处，它们是完全平的。这也意味着行程减少，主观印象更差。咔嚓声也相当响亮，而且还有点咔嚓声。TrackPoint本身运作良好，我们没有遇到任何光标漂移的情况。
显示屏 - WQHD，16:10
联想为第四代ThinkPad P1配备了IPS显示屏和16:10长宽比。默认屏幕已经是WQHD面板，分辨率为2560 x 1600像素，还有两个可选的4K屏幕（UHD+，HDR，一个带触摸功能）。我们测试装置中的标准显示屏提供了良好的主观画质，尽管是哑光表面，但明亮的表面不会出现颗粒感。内容很清晰，颜色显得很丰富。
制造商宣传的亮度为400尼特，对比度为1200:1，根据我们的测量，测试装置中的AU Optronics面板稍好一些（X-Rite i1 Pro 2 & CalMAN）。联想也在自己的ThinkBook 16p.我们没有发现PWM闪烁，响应时间也不明显。在最大亮度下，你可以注意到在黑色背景的右上角有一些混浊，但在日常工作中几乎看不出来。

该面板在开箱时就已经经过了很好的校准，只是在灰度中出现了轻微的绿色色调，但用肉眼几乎看不到。与sRGB参考色彩空间相比，DeltaE-2000的色彩偏差也非常小，大多数用户不需要额外校准。
我们通过校准成功地改善了画质（上面的盒子里有免费的配置文件），但最大亮度下降了30尼特。只有红色超过了3的重要标志，但由于全sRGB色域，该显示器仍然适合于图片/视频编辑。

16英寸的屏幕在户外效果很好，你仍然可以在明亮的环境中使用它。视角的稳定性也非常好。
性能 -Tiger Lake-H45和Nvidia T1200
处理器 - 酷睿i7-11800H
芯片酷睿i7-11800H来自英特尔的酷睿i7-11800H目前在许多笔记本中使用。它有8个核心（16个线程），最高时钟可达4.6GHz。联想将TDP限制非常慷慨地设定为109瓦，但这个数值纯粹是理论上的。然而，在实践中，该处理器甚至在其标称的45瓦特的TDP下艰难地运行。看一下我们下面的Cinebench循环数据就会发现，TDP很快就超过了50瓦特，但随后迅速下降到40瓦特以下。
对于一台昂贵的工作站来说，在纯粹的CPU负载情况下，这是一个非常糟糕的结果。与我们数据库中的i7-11800H的平均得分相比，i7-11800H也慢了20-30%。总而言之，CPU性能与采用第九代英特尔CPU的移动工作站相当（所以两年多了）。i7-11800H可以快得多，这一点从超薄的游戏笔记本电脑中可以看出Alienware x15，就是一个例子。AMD目前的移动处理器如Ryzen 9 5900HX在价格较低的ThinkBook 16p提供了更多的性能。我们已经迫不及待地想看看采用蒸气室冷却的机型将如何表现。
在电池供电的情况下，性能至少是稳定的。更多的处理器基准测试可在我们的 技术部分.

系统性能
从主观上讲，新的ThinkPad P1 G4是一个反应非常快的系统，但当你考虑到包括快速PCIe 4.0在内的组件时，这应该不足为奇。基准分数是平均水平，并不表明有任何限制。

DPC-Latency
我们的标准化延迟测试显示了一些问题，P1 G4不适合实时音频应用。4K视频播放（YouTube）也导致一些掉帧。我们希望联想能在即将到来的BIOS更新中解决这些问题。

GPU性能 - Nvidia T1200，60瓦特
Nvidia的新入门级专业GPU被称为T1200(Quadro的名称不再使用），与更强大的RTX型号相比，不支持光线追踪。联想将该GPU列为Max-Q型号，但Nvidia已不再使用Max-Q。该GPU基于图灵TU117芯片，所以它与消费版GeForce GTX 1650 Ti相当。它在P1 G4中的运行功率为60瓦，这是一个平均值（据Nvidia称35-95瓦是可能的）。我们的基准测试显示最大核心时钟为1840 MHz。
纯粹的性能比消费者的GPU稍好一些GeForce GTX 1650 Ti Max-Q在旧的ThinkPad X1 Extreme G3而且也明显领先于老款Quadro T1000/T2000。下一个专业GPU，即新的RTX A2000，明显更快。我们的专业SPECviewperf测试表明，新的T1200和它在某些情况下甚至相当接近RTX A2000。总而言之，Nvidia的新入门级GPU的性能很好。
在持续的工作负荷下，性能也很稳定，该设备轻松通过了苛刻的Time Spy 压力测试（98.2%）。TGP在电池电量上从60瓦特减少到35瓦特，这导致合成基准测试中的性能赤字约为15%。更多的GPU基准测试可在 这里.

排放--采用传统冷却方式的入门级ThinkPad P1
系统噪音
这两个风扇在空转和执行日常任务时非常安静，但当你使用高性能模式时，它们会偶尔开始旋转。我们建议你在浏览网页或观看视频时使用平衡模式（左键点击任务栏中的电池符号），那么你通常会享受到一个安静的设备。我们也没有注意到任何电子声或线圈啸叫。
更多的负载（游戏、纯粹的CPU/GPU负载或综合负载）很快就会导致最大的风扇噪音几乎达到47 dB(A)，这是很明显可以听到的。虽然风扇杂音的频率并不高，也不令人讨厌，但在比较安静的环境中会引起注意。我们还建议在游戏时戴上耳机。我们还不能说任何关于蒸汽室冷却的行为。

温度
ThinkPad P1 G4在执行普通任务时没有任何温度问题，但在游戏过程中或当你真正给笔记本施加压力时，有一些地方的温度超过了50℃。在这些情况下，你不应该把这个移动工作站放在你的腿上。
看一下处理器和显卡的数据，我们注意到两件事。GPU是系统的首选，在压力测试中可以保持其60瓦的TGP，而处理器只得到20瓦。冷却方案似乎没有太多的余地，因为两个风扇已经转得很快了。对于移动工作站来说，压力测试中的低CPU性能再次让人有点失望，因为它应该提供高而可靠的性能数据。
配备RTX A2000 GPU使用相同的传统冷却设置的型号，要么会遭受更高的表面温度，要么GPU在综合工作负荷下也会被限制在60瓦。
(-) The maximum temperature on the upper side is 50.6 °C / 123 F, compared to the average of 38.2 °C / 101 F, ranging from 22.2 to 69.8 °C for the class Workstation.

(+) The palmrests and touchpad are reaching skin temperature as a maximum (35.5 °C / 95.9 F) and are therefore not hot.

两个立体声扬声器（2x 2瓦）位于键盘旁边，将声音导向用户。联想安装了杜比访问应用程序，它提供不同的预设（包括可定制的预设）。你应该确保杜比软件正在运行，否则模块会听起来很尖锐和安静。一旦软件运行，你就可以享受到非常好的声音，可以轻松跟上其他好的多媒体笔记本电脑。我们只希望看到一个小型的专用重低音扬声器，以获得更多的冲击力。

消耗功率
ThinkPad P1 G4是我们对比组中空转时最高效的设备之一。总而言之，结果是不明显的，在压力测试中我们可以测出短时间内几乎不超过130瓦，但很快就会平息在110瓦左右。附带的170瓦电源适配器是绰绰有余的，并且在负载下仍有空间为电池充电。然而，联想应该再次关注待机消耗，待机消耗太高，约为2瓦特。

电池运行时间
90Wh的电池使实际运行时间达到9小时左右（Wi-Fi和视频测试为150尼特），这几乎与旧的思考板P1.当你使用最大亮度时，Wi-Fi运行时间下降到6.5小时左右；负载下的最小运行时间为90分钟左右。

Pros
Cons
结论 - ThinkPad P1 G4的CPU性能平平
联想用第四代ThinkPad P1进行了重大更新。最明显的变化是新的16英寸显示屏，长宽比为16:10，而机箱尺寸基本没有变化。新的入门级面板已经提供了WQHD分辨率，在我们的测量中留下了良好的印象。第二个明显的变化是键盘，它现在与较小的兄弟姐妹ThinkPad X1 Carbon G9相似。我们对这一发展相当挑剔，因为输入设备肯定比以前的型号下降了。以前的ThinkPad曾经拥有出色的键盘，但似乎这已成为过去。当然，新键盘无论如何都不差，但与来自戴尔或惠普的对手相比，没有更多优势。
新的联想ThinkPad P1 G4有一些积极的变化，比如更大的16英寸屏幕或良好的扬声器。但输入设备的发展是一个问题。键盘还不错，但以前的型号提供了明显更好的输入设备。
考虑到性能，我们的入门级配置给人留下了混合印象。新的Nvidia T1200 GPU性能良好，在负载下提供稳定的性能，但处理器的问题更大。联想使用了英特尔的45W CPU，但P1 G4在纯粹的CPU负载下甚至难以维持这个标称的TDP，它很快就降到了40W的水平。综合工作负载仅导致CPU的功率为20W，这对于昂贵的移动工作站来说很难说是一个好结果。
总而言之，新的ThinkPad P1 G4再次成为一个非常好的移动工作站，但是有一个问题。CPU的性能，特别是在综合工作负载的情况下，是相当低的。另一方面，Nvidia的T1200 GPU表现良好，尤其是在专业基准测试中。
考虑到ThinkPad P1 G4（或X1 Extreme G4，分别）有两种基本型号，情况就更复杂了。配备 "较小 "GPU的型号使用带有热管的传统冷却解决方案，这需要较小的空间，并为第二个M.2-2280插槽以及可选的WWAN模块提供空间（但P1 G4不具备WWAN功能）。拥有更强大的GPU的型号（至少是RTX A3000或X1 Extreme G4的RTX 3060）得到一个新的蒸汽室冷却，但它需要更多的空间，可能也有点重。
我们目前正在审查戴尔的新 Precision 5560而且我们预计下周会有更强大的ThinkPad P1 G4版本，配备GeForce RTX 3070和亚光4K显示屏。我们已经迫不及待地想知道新的蒸气室冷却的表现如何。
价格和可用性
我们的评测单元在Lenovo.com上以2319美元的价格上市。而其他型号也可提供。
