联想 ThinkPad T14s G4 酷睿 i7 笔记本电脑评测:与 AMD Ryzen 7 的艰苦较量
久负盛名的 ThinkPad T14s 系列今年又回来了,其 SKU 种类繁多,包括英特尔、AMD、IPS 和 OLED 等多种选择。我们已经评测过 AMD和 OLED系统,因此现在是检验英特尔 IPS 配置的最佳时机,看看它的比较结果如何。
我们的测试机配备了酷睿 i7-1365U vPro 和 1200p IPS 显示屏,售价约为 1400 美元。这是较实惠的配置之一,因为它不包括一些奢侈品,如广域网、智能卡和 500 万像素网络摄像头。
ThinkPad T14s 与其他 14 英寸商务笔记本竞争,如戴尔Latitude 7440,惠普 EliteBook 845 G10或 华硕 ExpertBook B9.

案例
要区分英特尔配置和 AMD 配置,除了它们的贴纸徽标外,还有一个简单的方法,那就是寻找 USB-C 端口旁边的 Thunderbolt 图标。除此之外,英特尔和 AMD 配置的机箱设计相同,没有其他视觉差异。
交流
与 Wi-Fi 6E(6 GHz)网络配对时,无线局域网性能稳定而出色。如下图所示,Wi-Fi 6(5 GHz)的性能稍显不稳定,但它仍然是可靠和完全可用的。
网络摄像头
我们的测试机配置的是 200 万像素网络摄像头,而不是 AMD 设备上的 500 万像素。红外摄像头是可选配置,而隐私滑块则是标配。
维护
显示屏
总共有以下六种(!)显示屏可供选择。我们的测试设备配置的是粗体字显示屏,它是最便宜的选择之一。
- 1920 x 1200,IPS,300 尼特,触摸屏,哑光,~60% sRGB
- 1920 x 1200,IPS,300 尼特,哑光,~60% sRGB
- 2240 x 1400,IPS,300 尼特,哑光, ~60% sRGB
- 1920 x 1200,IPS,400 尼特,哑光,100% sRGB
- 2800 x 1800,OLED,400 尼特(500 尼特 HDR),亮面,100% DCI-P3
- 1920 x 1200,IPS,500 尼特,触摸屏,哑光,100% sRGB
正如我们下面的测量结果所示,与高端面板相比,选择低端面板会明显牺牲色彩和亮度。我们建议至少选择第四种具有完整 sRGB 覆盖范围的面板,尤其是在进行图形编辑和改善户外可见度时。
没有高于 60 Hz 的显示屏可供选择,这是一个遗憾,因为与之竞争的 14 英寸子笔记本,如华硕专家本 B9拥有 90 Hz OLED 面板。

该显示器未经校准,其平均灰度和色彩 deltaE 值分别为 4 和 3.72。正如我们下面的 CalMAN 屏幕截图所示,通过自行校准可以解决色温过高的问题,从而获得更准确的灰度和色彩。即便如此,由于上述色彩覆盖面较窄的原因,在饱和度较高的情况下,显示器仍然会变得更加不准确。

性能
测试条件
在运行下面的基准测试之前,我们将 Windows 设置为性能模式。联想 Vantage 没有自己的电源配置文件集,以减少混淆。
处理器
酷睿 i7-1365U 酷睿 i7-1365U的单线程性能仅比 酷睿 i5-1335U.除此之外,这两款处理器的多线程性能几乎相同。您必须考虑 AMD Zen 4 配置才能获得更高的性能。
性能的可持续性只能算一般。例如,在循环运行 CineBench R15 xT 时,多线程性能会随着时间的推移下降约 20%,这表明 Turbo Boost 速度正在减慢。

鸢尾花 Iris Xe 96 EUs该升级了,因为它已经落后于 AMD 近期推出的替代产品。Radeon 780MRadeon 780MAMD 版 ThinkPad 14s G4 中的 Radeon 780M 可将性能提高 40% 至 60%,这绝不是微不足道的。降级到酷睿 i5-1335U 配置和 Iris Xe 80 EUs而不是 Iris Xe 96 EU,图形性能将受到 25% 至 30% 的影响。

系统噪音
风扇噪音,或者更确切地说,没有风扇噪音,是 ThinkPad T14s G4 的一大优点。尤其是当负载要求较高时,我们的英特尔设备运行时比 AMD 配置略微安静。换句话说,在需要更高转速之前,内部风扇可以保持更长时间的安静。

压力测试
在启动 Prime95 压力测试时,CPU 会升至 3.8 GHz、53 W 和 100 C。不过,大约 10 秒钟后,CPU 会降至 2.5 GHz 和 23 W,以保持 77 C 的核心温度。这种短暂的 Turbo Boost 潜能在搭载 U 系列处理器的超极本中很常见,与我们上述的 CineBench R15 xT 结果一致。
运行时的核心温度 Witcher 3时的核心温度稳定在 73 摄氏度,而最近的 Pavilion Plus 14的温度为 77 摄氏度。

耗电量
我们的英特尔系统在台式机上空转时比 AMD 系统略高几瓦。将这种情况延长几个小时,微小的差异就会增加,下一节的电池寿命结果就是例证。
由于酷睿系列的 Turbo Boost 潜能普遍较高,因此在启动 CPU 密集型任务时,英特尔设备的功耗要比 AMD 设备高得多。不过,功率峰值只会持续几秒钟,然后英特尔和 AMD 机型的功耗就会趋于正常,如下图所示。
每瓦性能显然对 AMD 有利。运行 Witcher 3或 Prime95,在考虑节流因素后,两款机型的要求大致相同,但 AMD Ryzen 7 配置的多线程 CPU 性能和图形性能明显快于英特尔酷睿 i7 配置。

结论 - AMD 的激烈竞争
酷睿 i7 vPro ThinkPad T14s G4 是目前最快的英特尔配置,但仍然比便宜的 Ryzen 7 Pro 配置在多线程 CPU 性能和图形性能方面都要慢一些。不仅如此,尽管整体性能较慢,但电池续航时间实际上比 AMD 方案更短。仅凭这些缺点,我们更倾向于推荐 AMD Ryzen 7 配置,它的售价为 1200 美元,比我们的酷睿 i7 评测配置(配备相同的 16 GB 内存、512 GB 固态硬盘和 1200p IPS 触摸屏)低 200 美元。
无论如何,酷睿 i7 ThinkPad T14s G4 并不可怕。相反,英特尔 U 系列处理器在性能上要逊色于 AMD Zen 4 处理器,尤其是 Ryzen 7 7840U。
英特尔 U 系列处理器支持 Thunderbolt 技术,而 AMD U 系列处理器则配备了 USB4 接口,可支持大多数 Thunderbolt 设备,如 eGPU 和显示器。因此,对于绝大多数用户来说,选择英特尔而不是 AMD 的好处微乎其微。用户可以选择 Ryzen 7 设备,然后配置 WAN 或智能卡等其他辅助选件,这样可以省钱或获得更多实惠。
价格和供应情况
目前,联想已经推出了多种配置的ThinkPad T14,英特尔配置的起价为1110美元,AMD配置的起价为920美元。我们的英特尔酷睿 i7 配置售价约为 1400 美元。
