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。

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。

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。
