联想ThinkPad L14 G3 AMD笔记本电脑评测。长电池寿命加上AMD动力
除了几个令人兴奋的改进，联想ThinkPad L14 G3 AMD也比ThinkPad T14 G3 有一些优势。在本评论中，我们将讨论它们是否足以使L14成为更好的选择。L14 G3有两个内存插槽--这是T系列的一个进步，T系列的AMD机型甚至只配有焊接的内存。
L14同样比T14的英特尔变体有一个至关重要的优势：25瓦的更高功率限制和更好的冷却解决方案。因此，主要针对商业用户和公司的L系列，现在也有可能对消费者产生吸引力。
与上一代L14相比，新设备的底盘明显更薄，看起来更像 ThinkPad E14.此外，一些型号的电池容量已经增加到63Wh（以前是45Wh）。也就是说，在材料的选择上也有变化，不一定是最佳的。我们将在后面的评论中更多地讨论这个问题和其他变化。ThinkPad L14 G3直接与笔记本电脑竞争，如 惠普ProBook 445 G8以及 戴尔Latitude 14 5420和 Inspiron 14 5425.

外壳：ThinkPad L14拥有一个紧凑的尺寸
ThinkPads通常是黑色的。上一代机型就是这种情况。相比之下，新L14的颜色绝对可以说是灰色。
通常情况下，L系列在其结构中使用了大量的塑料。联想再次没有包括一个镁质框架来加固笔记本电脑，与前辈L14 G2不同。.一些联想的机型配备了部分由碳制成的底座，以及可选的铝制盖子。我们的评测单元没有这些功能。
不幸的是，机箱在掌托周围的区域会出现弯曲，尽管这在日常使用中不是一个问题。同样，我们希望机盖能更硬一点。铰链非常结实，可以防止你用一只手打开笔记本电脑，但显示屏可以向后折叠180°。设备的表面在大多数情况下是光滑的，盖子的质地略显粗糙。在装配和完成方面，我们没有注意到笔记本电脑机身的任何缝隙或缺陷。
显示器周围的边框变得相当薄，导致屏幕与机身的比例达到81.8%。因此，ThinkPad L14 G3比E14 G3更加紧凑。 ThinkPad E14 G3.它的侧面也比E14 G3短1厘米（0.4英寸）。 侧面比ThinkPad T14另一方面，由于采用了16:10的显示屏，它更窄。
此外，新的L14比其前身轻约200克（0.44磅），在审查配置中重1.566公斤（3.45磅），使其与竞争对手处于同一水平。最轻的L14型号为1.39公斤（3.06英寸），电池选项占了重量差异的一部分。
联想ThinkPad L14 G3具有广泛的功能
在端口选择方面没有什么变化--这是件好事。除了一个HDMI 2.0输出，一个microSD读卡器和一个千兆以太网端口（幸好已经移到了后面），该设备上有四个USB端口：2个USB-C（最大10 GBit/s），都支持PD 3.0和DisplayPort 1.4，以及2个USB-A 3.2 Gen 1.然而，你不会得到任何雷电或USB 4支持。
SD卡阅读器
我们用我们的参考卡AV PRO micro SD 128 GB V60测试了ThinkPad L14上的SD读卡器，发现它的读写速度相当一般。相比之下，ThinkPad L14上的读卡器戴尔Latitude 14 5420的读卡器表现要好得多，提供的传输速度要高两到三倍。

连接性
来自AMD/Mediatek的可替换Wi-Fi 6模块在我们的比较中几乎完全领先。根据我们的测量，与上一代ThinkPad L14相比，其发射和接收速率几乎翻了一番。此外，新的L14型号都没有配备缓慢的Realtek芯片。
我们的评测机型是可以使用WWAN的（即它有一个免费的M.2插槽和一根天线线）。蓝牙5.1没有给我们带来任何问题，这与越来越多的关于配备最新AMD处理器的ThinkPads的报告相反。NFC可作为一个选项。

网络摄像头
安全问题
在ThinkPad L14 G3上，联想将可选的指纹识别器集成到了电源按钮上。这款笔记本电脑还为企业用户配备了一整套安全功能，包括TPM 2.0、智能卡读卡器、肯辛顿插槽、带物理快门的红外摄像头和Mirametrix Glance.
辅料
虽然L系列缺乏一个对接端口，但它仍然可以连接到USB-C底座上。在包装盒中，你只会发现笔记本电脑附带的65瓦USB-C电源适配器。而90%的包装都是由可回收或来自可持续林业的材料制成。
维护
卸下11颗十字头螺钉后，你可以用飞刀卸下底盖。但要小心：塑料夹子很容易断裂。
在我们看来，内部结构有很多优点：两个内存插槽，一个可拆卸的Wi-Fi模块，一个用于WWAN的免费M.2插槽，一个容易维护的冷却系统，以及一个可更换的SSD。与前代产品不同的是，L14 G3使用的固态硬盘具有更短的M.2 2242外形尺寸，以适应更大的电池（也可更换）。其中一个USB-A端口在一个子板上，因此如果它坏了也可以更换。
担保
联想在德国和美国都为L14 G3提供了12个月的保修。虽然我们的校园机型配有高级现场支持，但默认的保修只提供快递或携带服务。但是，你可以升级和延长保修期，大约95欧元（99美元），三年，大约210欧元（189美元）。
伟大的输入设备有一些怪癖
键盘
从第一代开始，ThinkPad L14的键程就比较短，为1.5毫米（0.06英寸）。这意味着如果你喜欢1.8毫米（0.07英寸）的键程，E系列仍然是唯一的选择。六排全宽键盘打字非常舒适、快速和安静。
联想在其ThinkPad上使用了来自不同供应商的键盘；我们评测单元上的键盘是由Sunrex制造的，感觉没有我们的ThinkPad T16上的键盘那么清晰。 键盘，感觉不如我们的ThinkPad T16评测样本上的键盘感觉更清晰。由于缺乏镁质框架，键盘在被刻意压下时表现出明显的弯曲。在打字时，你只会注意到数字键6至9和向下箭头键有一些弯曲。所有重要的特殊功能键都是专用的。
触摸板和跟踪点
触摸板现在宽了15%，但短了同样的百分比，尺寸为11.5×5.5厘米（4.53×2.17英寸）。略显粗糙的Mylar表面并不像目前T系列机型那样光滑。但它的使用感觉仍然很好。触摸板反应灵敏、精确，能够毫无延迟地识别普通手势。集成按钮的点击深度很低，但按起来感觉很沉闷。
键盘中间的红色TrackPoint像预期的那样工作，让你在屏幕上快速而精确地移动鼠标光标。下面的三个TrackPoint按钮现在是完全平的。尽管如此，它们仍然提供了一个明显而准确的点击。
可选的低功耗显示器能够达到400尼特
我们的评测单元配备了一个哑光的全高清IPS显示屏（1,920 × 1,080），长宽比为16:9，尽管ThinkPad L13已经跳到了16:10的显示屏。在这个分辨率下，屏幕看起来足够锐利，并且由于其1219:1的巨大对比度和0.24尼特的低黑度，能够产生相对饱和的黑色。在7,071K时，白点并没有完全达到6500K的最佳值。
该屏幕的峰值亮度较低，为282尼特。如果可能的话，你应该选择低功耗显示选项，因为400尼特的亮度更高，因此对户外使用更实用。我们没有检测到任何PWM闪烁的情况。除了 IdeaPad 5 Pro 14和 ThinkPad T14 G3之外，比较中的所有其他设备都有类似的性能水平。
有以下显示选项（均为哑光）。

ThinkPad L14的性能很好，但有稳定性问题
我们的评测单元配备了一个8GB的内存模块，可以支持高达64GB的DDR4-3200内存，分为两个SODIMM模块。它还具有一个六核的AMD Ryzen 5 PRO 5675UBarcelo CPU，集成 Vega 7图形和一个PCIe 4.0 SSD的256GB存储。
这些硬件对于办公和商业用途来说已经足够了，但我们建议升级到至少16GB的内存，以满足更苛刻的任务。L14 G3的其他AMD型号有四到八个核心的CPU，而英特尔的变种则有从 酷睿i3-1215U到 酷睿i7-1260P.
测试条件
在ThinkPads上，联想已经将性能模式整合到Windows电源选项中。在进行所有与性能有关的基准测试时，我们使用了高性能配置文件并禁用了自动模式。
在 "最佳性能 "和 "更好的性能 "模式下，AMD处理器最初消耗了30瓦的电力，然后分别在40秒和25秒后将其电力使用减少到25瓦。在 "更高的电池效率 "模式下，功耗在几分钟内从21瓦特逐渐下降到18瓦特。
处理器
对于AMD Ryzen 5 PRO 5675U ，25瓦的功率限制是合理的。该处理器能够比ThinkPad T16 （限制在20瓦）中的英特尔Alder Lake CPU的持续性能高出30%。
有趣的是，新的L14的CPU性能与它的上一代的八核Ryzen CPU 。但是，我们的数据库 ，表明在相同的功率限制下，使用八个塞尚/巴塞洛U核心，你将获得大约25%的性能提升。
由于有两根铜质热管，温度在很长一段时间内只达到75℃（167℉）。相比之下，L14 G3的英特尔变体只配备了一根热管，与ThinkPad T系列类似。在我们的比较中，所有其他设备由于采用了六核AMD CPU，大多提供了类似的性能。
在电池上，持续性能没有下降。32秒的初始提升至30瓦的功能被简单地禁用（见电源使用记录和截图）。
也就是说，我们遇到了一个非常恼人的错误：每次从睡眠模式唤醒后，CPU会在500到800MHz左右徘徊。这个问题只能通过重启笔记本来解决，然后导致功率限制停留在20瓦。我们并不真正理解什么时候以及为什么我们能重新获得25瓦的完整功率限制。

系统性能
根据我们的经验，系统性能非常快。应用程序和网站的加载没有任何延迟，即使在后台播放4K视频时也是如此。尽管采用了单通道内存，但合成基准测试结果与竞争对手的水平大致相同，比采用英特尔Alder Lake处理器的ThinkPad T16略好。然而，Alder Lake处理器在网络浏览基准测试中具有相当大的领先优势，这是因为它具有更高的射程涡轮增压。

大容量存储
我们的评测单元安装了一个Kioxia/东芝BG5 PCIe 4.0 SSD。由于空间限制，不得不使用外形尺寸较短的M.2 2242的驱动器。因此，ThinkPad L14 G3的存储速度比上一代产品的PCIe 3.0固态硬盘还要慢。尽管如此，你只有在日常使用中复制大量数据时才会注意到这一点。

图形卡
图形处理是由Radeon RX Vega 7.图形性能不是很好，因为GPU受到单通道内存的约束。
即使是老游戏也必须在低设置下进行。但是考虑到该设备不是为游戏而设计的，而且你可以通过添加第二个内存模块来提高性能，这对ThinkPad L14来说是没有问题的。
也就是说，如果不是因为以下问题的话。Far Cry 5在多次尝试和重启后仍拒绝启动，而且每次我们试图运行GRID Legends时，L14都会重新启动。关于这一点，请看 "压力测试 "部分。
用电池运行笔记本并不影响图形性能。

排放。联想办公笔记本运行安静且相当凉爽
噪声排放
你很少会听到来自L14的任何风扇噪音。笔记本电脑必须要运行高要求的软件，你才能注意到风扇的声音。在浏览互联网时，你可以同时打开尽可能多的标签，但很少会听到来自风扇的任何声音。即使在最大负荷下，风扇的噪音也从未超过31.7分贝（A）。对比组中的大多数设备都运行得更响，特别是在最大负荷下。
然而，当笔记本电脑处于持续负载或运行游戏时，风扇频繁地旋转起来，每次都会产生一个响亮的、略微恼人的高音调噪音。在我们的评测单元上，我们没有检测到任何线圈的啸叫。

温度
在最大负荷下，在底板右侧朝后的位置有一个热点，温度达到45.8℃（114.4℉）。不过在日常负载情况下，ThinkPad L14 G3并没有变得那么热，即使是在机箱的那个特定区域，也可以在膝上使用而没有问题。
笔记本电脑上的所有其他区域触感都相当凉爽。相比之下， ThinkPad T14 G3 AMD和 ThinkPad E14 G3 AMD的运行温度都很高。
(±) The maximum temperature on the upper side is 40.4 °C / 105 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(-) The bottom heats up to a maximum of 45.8 °C / 114 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 27.4 °C / 81 F, compared to the device average of 29.5 °C / 85 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 34.3 °C / 94 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 31.9 °C / 89.4 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (-4.3 °C / -7.7 F).

压力测试
我们无法为我们的综合压力测试（同时运行Prime95和FurMark）获得任何数据，因为每次我们试图这样做时，系统就会崩溃。这本身就是一个结果，表明系统有稳定性问题--这是我们以前在尝试启动一些游戏时遇到的问题。至少在系统进行纯粹的CPU压力测试时，CPU没有节流，运行在2.72GHz，这仍然高于其基本时钟。
一个缺点是，核心温度确实达到了95°C（203°F）的关键水平。作为比较， L14 G2没有超过65°C（149°F）。当系统仅在图形负载下，GPU温度达到86°C（187°F），这是不寻常的高。假设一下，这可能是联想的员工对散热膏使用得太重了。

发言人
向上发射的扬声器声音不大，最大音量只有68分贝（A）。但至少有一丝低音，而且高音和中音听起来平衡而平缓。尽管如此，如果你真的想享受音乐，我们建议通过音频插孔或蓝牙将笔记本电脑连接到外部音频设备。

电源管理。ThinkPad L系列终于获得了良好的电池寿命
消耗功率
尽管L14 G3的空闲功耗不算太差，但 ThinkPad T14 G3 AMD相比之下，ThinkPad T14 G3在闲置时需要的电量要少得多。
在负载情况下，该设备消耗约30瓦的电力，鉴于指定的功率限制，这符合我们的预期。即使是一个45瓦的电源适配器也不会有任何区别。

电池寿命
由于电池容量增加了23%，ThinkPad L系列的一个主要缺陷终于得到了解决。我们的评测单元配备了57Wh的电池。在屏幕亮度为150尼特的情况下，L14 G3在我们的Wi-Fi测试中成功地持续了13小时以上。这是一个很好的结果，使该笔记本在比较中领先于所有其他设备。即使使用45Wh的电池选项，你仍然可以期待该设备的电池寿命超过10小时。对于那些想要更大电池的人，还有一个63Wh的选项。

Pros

评语。是ThinkPad T14的最佳替代品
联想ThinkPad L14 G3是一款不错的办公笔记本电脑，与前代产品相比，它拥有更大的电池和更薄的机箱。再加上它有两个内存插槽，出色的CPU性能、安静的运行和低功耗的显示选项使L14成为流行的ThinkPad T14的一个有吸引力的替代品。，后者运行温度较高，并有一个焊接的Wi-Fi模块。T14的AMD变体甚至有完全焊接的内存。
有一点是肯定的：L14在输入设备和外壳坚固性方面没有接近ThinkPad T14，尽管键盘和触控板对于这个价格来说是很好的。如果你不介意有些更基本的机箱，你可以用1,019欧元（1,104美元）购买L14，而不是T系列笔记本电脑，这样可以节省很多钱。
L14 G3可能是受欢迎的ThinkPad T480当之无愧的继任者。它提供两个内存插槽，电池寿命长，性能好，排放低。还有一个很好的显示屏选择。
然而，我们的评测单位配备的显示屏亮度不足（282尼特），仅覆盖61%的sRGB色域。因此，如果有这个选项，你应该选择更明亮的低功耗显示屏。同样令人遗憾的是，联想保留了16:9的长宽比，故意将该产品与ThinkPad T14区分开来。
那些绝对想要更长键程的人应该看看ThinkPad E14 。它在大多数方面的性能与L14惊人地相似，只是在端口选择和与商业有关的安全功能方面落后。但E14至少有一个内存插槽。如果你想以较低的价格获得16:10的显示屏，你可以考虑购买IdeaPad 5 Pro 14 或Dell Inspiron 14 。后者也有两个内存插槽，但其键盘没有那么好。
价格和可用性
我们的评测单位是，是为学生和教育工作者准备的特殊型号(仅在德国销售），价格为939欧元（915美元）。一台，存储量为512的AMD型号的AMD机型，价格约为1,699美元。
ThinkPad L14 G3的英特尔型号起价为1399美元，可直接从Lenovo US购买。.
