联想 ThinkPad E14 G5 英特尔笔记本电脑评测:酷睿 i7-1355U 对 Ryzen 7 7730U
在最近评测了 ThinkPad E14 G5 AMD 版之后,我们现在准备评测 ThinkPad E14 G5 Intel 版。这两个版本的机箱设计相同,因此我们建议查看 我们对 AMD 版的评测了解该机型的更多物理特性。不过,两者之间还是存在一些内部差异,我们将在下面的评测中提及。
我们的测试机是英特尔的中间配置,配备第 13 代 Raptor Lake 酷睿 i7-1355U CPU 和 1200p FHD+ 显示屏,售价约为 915 美元。其他 SKU 从酷睿 i3-1315U 到酷睿 i7-13700H,可选GeForce MX550 显卡和分辨率更高的 2240 x 1400 IPS 显示屏。可配置的范围比预期的要宽,尤其是对于 14 英寸的子笔记本而言。
ThinkPad E14 G5 的替代产品包括其他中高端商务子笔记本,如HP EliteBook 845 或戴尔Latitude 7440 。

案例
要区分 ThinkPad E14 G5 英特尔版和 AMD 版,最简单的方法也许就是寻找左侧边缘的 Thunderbolt 徽标。AMD 版本不支持 Thunderbolt 和 USB4,因此英特尔版本在扩展坞功能方面更胜一筹。
交流
英特尔 AX201 支持 Wi-Fi 6 和蓝牙 5.1。需要 Wi-Fi 6E 连接的用户可选配价格更高的 AX211。

网络摄像头
虽然隐私快门是所有型号的标准配置,但 1080p 分辨率和红外传感器是可选配置。低端型号可能配备 720p 传感器。
维护
英特尔和 AMD 版本的一个有趣区别是,英特尔版本不支持全长的 M.2 2280 固态硬盘,如下图所示。最多仍可安装两个驱动器(PCIe4 x4 + PCIe3 x4),但每个驱动器的长度必须不超过 42 毫米(2242)。
配件和保修
包装盒内除了交流适配器和文件外没有其他附件。如果在美国购买,制造商提供一年有限保修。
显示屏
有以下三种显示选项:
- 1920 x 1200、IPS、60% sRGB、60 赫兹、300 尼特、非触摸、哑光
- 1920 x 1200,IPS,60% sRGB,60 赫兹,300 尼特,触摸,哑光
- 2240 x 1400、IPS、100% sRGB、60 赫兹、300 尼特、非触摸、哑光
我们的 AMD 设备配置的是 1400p 面板,而我们的英特尔设备配置的是粗体选项。如果您的工作负载需要更准确的色彩和更高的对比度,我们建议您使用 1400p 面板。除此之外,亮度和黑白响应时间等其他属性在所有选项中似乎都是一致的。

性能
测试条件
测试前,我们将 Windows 设置为性能模式。联想没有提供任何专门的电源配置文件,而是依靠 Windows 的电源配置文件来减少混乱。
处理器
处理器性能低于预期,比我们数据库中配备相同的 酷睿 i7-1355U.这一不足可归因于系统较弱的 Turbo Boost 可持续性。例如,当循环运行 CineBench R15 xT 时,如下图所示,最初的 1539 分将在第二次循环时下降 35% 至 40%。
与 Ryzen 7 7730U相比,我们的酷睿 i7-1355U 的单线程性能提高了 25% 至 30%,但在考虑节流因素后,多线程性能降低了 25% 至 30%。

图形处理器性能
内存仅为 DDR4-3200,速度低于平均水平,这对集成显卡性能产生了负面影响。我们的 Iris Xe 96 EUs与我们数据库中采用相同 GPU 的普通笔记本电脑相比,速度要慢 10% 到 15%,原因是 CPU 和内存速度太慢。整体性能与 RX Vega 8的性能差不多。

系统噪音
AMD 和英特尔版本的风扇噪音差别不大。在游戏等高负载情况下,每个版本的风扇噪音最大值相近,都略高于 40 dB(A),而在浏览或流媒体等低负载情况下,仍会出现轻微的风扇脉动。在运行中低负荷时,风扇很容易被忽略。

压力测试
启动 Prime95 压力时,CPU 时钟频率和主板功耗将分别飙升至 4 GHz 和 52 W,持续约 30 秒,核心温度为 97 C,然后处理器将在 1.6 GHz 至 3.9 GHz 和 14 W 至 43 W 之间循环,以保持较低的核心温度,如下图所示。时钟频率节流范围非常大,这也是上文提到的 CineBench 结果慢于预期以及下一节中功耗数据范围较大的原因。
当运行压力较大的负载时,核心温度会徘徊在 80 摄氏度左右,而戴尔 7440 的核心温度则略低于 70 摄氏度。 戴尔Latitude 7440.

能源管理
耗电量
功耗行为反映了上文提到的急剧的 CPU 节流行为。例如,在运行 Prime95 时,功耗会在 29 W 和 67 W 之间循环,而在 AMD ThinkPad E14 G5 上进行完全相同的测试时,功耗会稳定在 47 W。
当 CPU 的利用率达到 100% 时,小巧(9 x 4.7 x 2.7 厘米)的 65 W USB-C 交流适配器的功耗可高达 67 W。因此,当 Turbo Boost 达到最快时(如多任务或启动应用程序时),英特尔系统比 AMD 系统更耗电。如下图所示,在启动 CineBench R15 xT 基准测试时,也可以观察到这一点。此外,在桌面空闲或运行要求不高的负载时,两个版本的耗电量基本相同。

电池寿命
与我们的 AMD 配置相比,某些英特尔配置的电池容量较小(47 Wh 对 57 Wh),因此如果用户配置较小的电池,运行时间可能会缩短。在自动关机前,我们可以浏览约 5.5 个小时的网页,而 AMD 版本则需要近 10 个小时。
此外,使用随附的交流适配器从空闲状态充电到满载状态也非常快,只需一个多小时。快速充电功能默认已启用。

Pros
Cons
评语:不错,但与 AMD Ryzen 7 版本相比更难推荐
我们的英特尔产品配置了酷睿 i7 处理器、16 GB 内存、1200p 触摸屏和 512 GB 固态硬盘,售价约为 915 美元,而配置相同内存、触摸屏和固态硬盘的 Ryzen 7 版本售价为 865 美元。选择 AMD 版本将获得更快的多线程性能、更长的电池续航时间和适当的 M.2 2280 SSD 支持,而英特尔版本将获得更快的单线程性能和 Thunderbolt 支持。在图形性能、表面温度和风扇噪音等其他方面,两个版本也非常相似。因此,除非你真的很看重单线程性能和 Thunderbolt,否则对于大多数感兴趣的买家来说,AMD 版比英特尔版更容易推荐。
与价格较低的 Ryzen 7 相比,基于英特尔的 ThinkPad E14 G5 表现出更陡峭的节流行为。
ThinkPad E 系列缺少了一些以商务为中心的辅助功能,如广域网和智能卡,但这也是设计的初衷,因为 ThinkPad E 系列应该是更高端、更昂贵的 ThinkPad T 系列的经济实惠的替代品。 ThinkPad T 系列或 X 系列.
