你能买到的最快的酷睿i7-12700H笔记本电脑。联想Legion 5 15IAH7H评论
2022年的Legion 5 15是一个重大的更新,比起 2021年Legion 5 15.它采用了相同的GPU,尽管TGP目标更高(140W对130W),同时将CPU升级到最新的12代Alder Lake-H系列。外部机箱也进行了更新,以获得更新和更时尚的外观。
我们审查的配置是一个中端配置,配有Core i7-12700H,GeForce RTX 3060 GPU和1080p165 1080p IPS显示屏,零售价约为1600美元。其他SKU有较小的酷睿i5-12500H CPU,144赫兹显示屏,或更快的GeForce RTX 3070 Ti。
Legion 5 15的竞争对手包括其他中档的15.6英寸游戏笔记本电脑,如Razer Blade 15 Base Edition,Asus TUF Gaming F15,MSI Bravo 15, 或Acer Aspire Nitro 5 。Legion 5 15不应与Legion 5 Pro 相混淆,后者是一个更大的16英寸设计。

案例 -Legion 含有少量ThinkBook的案例
机箱保留了去年模型的总体审美,但所有侧面都有圆角,并重新设计了通风栅栏。更加干净的外观更接近于 思考本系列这可能不是一个巧合。与竞争者华硕TUF/ROG系列或微星系列相比,新的Legion 5 15看起来不那么像游戏机,而更像是半专业的。
机箱的刚性很强,但还达不到与 Razer Blade系列。例如,当试图扭转底座时,联想会表现出稍多的翘曲和吱吱作响,其显示屏也可以说是如此。铰链令人满意,但没有华硕TUF系列的超大铰链那么强。
由于Legion ,该模型更宽,因此比许多其他15.6英寸游戏笔记本电脑更重,因为大的突出的后部设计。虽然这有助于冷却和性能,但缺点是一个更笨重的笔记本电脑,不像许多替代品如Razer Blade 15 Base Edition那样适合旅行。
连接性 - 支持Thunderbolt 4
与基于AMD的2021型号相比,我们的英特尔型号将一个USB-A端口换成一个USB-C端口。两种型号之间的端口选项是相同的,只是重新安排了位置。大多数端口都在后面,与其他大多数游戏笔记本不同,无论好坏。
雷电4只支持沿左侧边缘的标示USB-C端口。
沟通
英特尔AX211是大多数SKU的标准配置,与Wi-Fi 6E和蓝牙5.2兼容。在与我们的6GHz网络配对时,我们没有遇到任何问题。

网络摄像头 - 低1MP质量
720p的网络摄像头的相机质量是浑浊的。也不支持Windows Hello。
维护
底部面板只需要一把飞利浦螺丝刀就可以拆下。用户最多可以添加/删除两个DDR5 SODIMM模块、两个M.2 PCIe4 x4 2280 SSD和一个M.2 WLAN模块。
配件和保修
除了交流电适配器和文件之外,盒子里没有其他东西。标准的一年有限制造商保修适用。
输入设备 - 伟大的键盘,海绵状的点击板
键盘
Legion 5 15采用了传统的基于膜的按键,而不是一些更高端的机型上的机械按键,如 诸如Alienware m15系列.尽管如此,与普通超极本的按键相比,Legion 上的按键反馈和行程更清晰、更深入。如果你经常打字,那么你可能会发现这里的键盘比便宜的IdeaPad或Dell Inspiron的键盘更适合办公任务。
所有配置中都有键盘背光,但有些只有单区白色,而有些则是四区RGB。没有每个键的RGB选项,可能是为了节省成本。所有按键和符号都会被照亮。
触摸板
点击板的大小与更昂贵的 "小白 "上的点击板相同。 Legion 7 1612 x 7.5厘米。反馈也是相同的,因此用户可以预期在按下时,会有一个有点海绵状的、不令人满意的点击。点击板的表面很光滑,就像周围的掌托一样,但我们建议使用一个外部鼠标,以便更容易地进行点击和拖动。
显示器 - 165赫兹,G-Sync,100% sRGB,IPS
与去年的机型相比,联想已经将IPS面板供应商从友达换成了CSOT。尽管如此,大多数属性几乎保持不变,以获得类似的观看体验。用户仍然可以得到G-Sync,100%的sRGB覆盖率,165赫兹的原生刷新率,快速的响应时间,明亮的350尼特背光,以及一个体面的~1000:1的对照率。一些SKU可能包括一个更便宜的1080p 144 Hz面板,由于其色彩空间较窄,我们建议避免使用。

在350尼特的情况下,该显示器只是比一般的游戏笔记本稍微亮一点,因为300尼特是很常见的。该屏幕在户外阴凉处观看很舒服,磨砂覆盖层有助于减少眩光,但如果在更明亮的条件下,一切都会变得很模糊。
性能 - MUX支持
测试条件
在运行以下任何性能基准测试之前,我们通过联想Vantage将系统设置为性能模式,将GPU设置为独立模式。强烈建议用户熟悉预装的Vantage软件,因为它是系统更新、MUX或混合图形模式、充电行为等的枢纽,如下面的截图所示。
处理器
CPU的性能比预期的要快,其结果比我们数据库中配备相同的笔记本电脑的平均速度快15%至25%。 酷睿i7-12700H处理器。事实上,Legion 5 15是你能得到的配备Core i7-12700H的最快型号之一。原始性能超过了 酷睿i7-12800H在更昂贵的 2022年的Razer Blade 15以明显的优势。
降级到一个较小的 酷睿i5-12500H配置后,单线程和多线程性能分别下降了5%和25%。

GPU性能--高140 W TGP
图形性能非常好,3DMark结果比我们数据库中配备相同的笔记本电脑快10%至15%。 GeForce RTX 3060GPU。高于平均水平的性能可以部分归因于140W的TGP目标,这比大多数其他游戏笔记本要高。
系统必须设置为性能模式,以充分发挥GPU的作用。例如,如果在平衡模式下运行,图形性能将下降约10%,正如我们下面的Fire Strike 结果所示。

系统噪音
与2021年型号的风扇相比,内部风扇在需要升温之前保持更长时间的安静。 2021型号.例如,当运行3DMark 06的第一个基准场景时,风扇噪音最高只有29.3 dB(A),而旧型号则为54 dB(A)。这意味着,在风扇变得可闻之前,你可以运行低至中度负载,如网络浏览或视频流,时间更长。
运行 Witcher 3在平衡模式下运行将导致风扇噪音水平在43至48 dB(A)之间,而在性能模式下运行时,噪音水平为51.4 dB(A)。因此,如果用户希望充分发挥GPU的作用,就必须忍受更大声的风扇。整体风扇噪音比Razer Blade 15基础版要大,但比Razer Blade 15基础版要安静。华硕TUF游戏F15每一个都有相同的GeForce RTX 3060 GPU。

压力测试
当运行Prime95对CPU施加压力时,时钟频率和电路板功耗将分别飙升至4.1GHz和110W,持续约一分钟左右。此后,CPU将稳定在3.6GHz,101W和97C。非常热的核心温度表明,与其他游戏笔记本相比,处理器正在推动冷却解决方案的极限,以挤压额外的性能。笔记本HP Envy 16例如,在类似的测试条件下,采用相同的Core i7-12700H CPU的惠普Envy 16将稳定在2.1 GHz和66 C。
运行在 Witcher 3如果在平衡模式下,GPU将稳定在1665 MHz、95 W和70 C,性能下降10%,详见上文的GPU性能部分。因此,如果用户想最大限度地利用GPU,必须通过Vantage软件启用性能模式。
用电池运行限制了性能。在电池上进行的Fire Strike 测试将返回物理和图形分数,分别为23698和12906分,而在主电源上则为30779和22257分。

能源管理--高CPU负载下的需求
消耗功率
该系统在桌面上闲置时要求异常苛刻。在混合图形的最低亮度设置和电源配置文件下,功耗在20W之间,而在dGPU激活的最高亮度设置和电源配置文件下,功耗为49W。相比之下,2021年的模型将在7瓦和16瓦之间。
运行时 Witcher 3需要大约187瓦,而去年的型号是175瓦,这与我们2022年的型号的TGP目标高出10瓦密切相关。
当CPU和GPU处于100%的利用率时,我们能够从大型(约19.8 x 9.8 x 2.5厘米)300瓦交流适配器中记录到268瓦的最大功耗。这个最大值比大多数其他运行在AMD或第10/11代英特尔平台上的游戏笔记本要高,因为第12代酷睿系列的要求更高。

电池寿命
由于电池容量仍为80Wh,WLAN的运行时间与去年的机型基本相同。当开启快速充电时,从空电到满电只需要35分钟,而其他大多数笔记本电脑则需要1.5到2小时。
只支持通过后部的USB-C端口进行USB-C充电。然而,充电可能只与可选的联想USB-C充电器兼容,而不是大多数第三方充电器。我们尝试了三个独立的USB-C充电器(30W、100W和130W),但只有联想的130W充电器能工作。

Pros

结论 - 大尺寸,大性能
2022年Legion 5 15的最令人惊讶的方面是它比平均水平更快的性能。尽管我们已经测试了大量的游戏笔记本,其中包括 酷睿i7-12700HCPU和 GeForce RTX 3060GPU,这款联想机型的运行时钟速率明显高于许多配备相同硬件的竞争对手。如果你担心不小心购买了一台硬件欠频的笔记本电脑,那么Legion 5 15将压制任何这种担忧。
2022年的联想Legion 5 15擅长在一个几乎半专业的机箱中最大限度地提高性能,并将RGB灯降到最低。然而,它是相当大和重的,而且一些辅助方面可以使用一些改进。
额外的性能是以更重更大的机箱为代价的。巨大的突起的后部很难被忽视,像华硕TUF游戏机F15 FX507ZM或Razer Blade 15 Base Model这样的竞争对手都明显较轻。如果你经常旅行,那么更高的性能可能不值得更重的重量。笨重的300W交流适配器也没有使联想的旅行非常友好。
对于未来的机型,我们希望看到对海绵状的点击板、像素化的网络摄像头质量、糟糕的第三方USB-C充电支持和小铰链的改进。特别是后者将有助于证明与竞争对手相比,更重的机箱是合理的。
价格和可用性
联想现在正在发货其Legion 5 15系列,起价为1100美元至1900美元,取决于配置。我们的具体审查配置目前以1350美元发货。
