机箱和连接性 - 配备 Thunderbolt 4 和 Power Delivery 的 B3
高质量的材料是徒劳的：做工精良的外壳由哑光黑色塑料制成，表面光滑。底座和盖子可以轻微扭动，但这并不影响正常使用。铰链调节得很紧，盖子的最大开启角度为 180 度。取下底板后，可以接触到电池和其他内部组件。
笔记本电脑配备两个 USB-A 端口（USB 3.2 Gen 2）和两个 USB-C 端口（1 个 Thunderbolt 4、1 个 USB 3.2 Gen 2）。后两个端口支持 Power Delivery，TB4 端口还可以输出 DisplayPort 信号。这意味着 B3 共有两个视频输出端口（HDMI、DP）。它没有 SD 读卡器。它的网络摄像头（0.9MP）在同类产品中并不突出，但至少有一个机械盖。
在最佳条件下（附近没有 WLAN 设备，笔记本电脑和服务器电脑之间的距离很短），它的 WiFi 数据传输率非常高。B3 使用的是 WiFi 6E 芯片（英特尔 AX211）。有线连接由英特尔公司的控制器（I219-LM；1 GBit/s）负责。ExpertBook 系列还有配备 LTE 调制解调器（型号B3404CMA）的机型。
输入设备 - 商务笔记本电脑配备背光键盘
chiclet 键盘的凹面按键（单级背光，可防止溅水）具有适中的升力和清晰的压力点。在我们看来，按键的阻力还可以再清晰一些。对我们来说，键盘的轻微弯曲并不是问题。不足之处方向键和回车键有点偏小。支持多点触控的点击板（约 13 x 8.2 厘米）可作为鼠标的替代品，其特点是抬起时间短，压力点清晰。
显示屏 - 16:10 面板，色彩空间覆盖率低
华硕为这款 ExpertBook 配备了 14 英寸哑光显示屏（1,920 x 1,200 像素），宽高比为 16:10，非常适合工作使用。效果不错：我们没有注意到任何 PWM 闪烁。亮度和对比度均未达到各自的目标值（大于 300 cd/m² 和 1,000:1）。您也可以选择配备亮度更高的 500 尼特面板（2,560 x 1,600 像素）的 B3。这两款显示屏还可选择用作触摸屏。

开箱后，屏幕显示的色彩还可以接受：不过，由于偏差在 5.5 左右，因此未能达到目标（DeltaE < 3）。校准显示屏后，该值降至 3.9，灰阶也更加均衡。该面板不支持 DCI-P3、sRGB 和 AdobeRGB 色彩空间--尽管大多数竞争对手的屏幕也是如此。另一款 500 尼特面板（WQXGA）据称能提供更好的色彩描绘（DCI-P3）。

性能 - Raptor Lake 和 Ampere 为 14 英寸设备提供动力
ExpertBook-B3-B3404C 系列是商务领域的 14 英寸笔记本电脑。该系列采用 Raptor Lake（B3404CVA、B3404CVF）和 Meteor Lake CPU（B3404CMA）。您可以选择配备专用 GeForce-RTX-2050GPU 的型号，我们的测试设备就是其中之一。
测试条件
您可以使用组合键 "Fn "+"F "在三种制造商特定的风扇模式（见表）之间切换。我们使用了性能模式（基准测试）和耳语模式（电池测试）。前者仅在连接电源时可用。这些模式会影响 CPU 和 GPU 性能。
| 性能模式 | 标准模式 | 低音模式 | |
|---|---|---|---|
| 功率限制 1 (HWInfo) | 35 瓦 | 35 瓦 | 17 瓦 |
| 功率限制 2 (HWInfo) | 55 瓦 | 55 瓦 | 55 瓦 |
处理器
酷睿 i7-1355U 酷睿 i7-1355U的 10 个 CPU 内核（2P、8E）的最高时钟频率分别为 5 GHz（P）和 3.7 GHz（E）。连续多线程负载（CB15 Loop）导致其时钟速率从第一次运行到第二次运行略有下降，从第二十一次运行到第二十二次运行再次下降。此后，每次都保持恒定水平。我们注意到基准值高于之前的 CPU 平均值（连接电源）。在电池模式下，单线程和多线程性能均减半。

图形卡
在 Nvidia 当前的 RTX GPU 阵容中，RTX 2050 GeForce RTX 2050(2,048着色器、64位总线、4 GB GDDR6、光线追踪、DLSS）的性能几乎垫底。华硕为其设定的 TGP 为 40 瓦。其基准测试结果和帧速率略高于 GPU 的平均水平。GPU 允许在低至高设置下进行全高清游戏。要求不高的游戏允许更多。目前的游戏通常需要降低设置。
TravelMate 和ThinkPad 配备的 iGPU 无法与 RTX 2050 相提并论。明显的区别在于它们的内存采用单通道模式运行。如果安装第二个内存模块，两台电脑的性能都会大幅提升。尽管拥有相同的 GPU，ProBook 也无法与 B3 匹敌--惠普将其 TGP 设置为 30 瓦。

排放与电力 - 电池续航时间长的华硕电脑
噪音排放
在日常使用中，风扇非常不活跃，经常完全静止不动。在负载情况下，笔记本电脑的噪音会大幅上升：我们注意到噪音值高达 49.3 dB(A)，但平均噪音值并不高。使用 "耳语"模式可降低总噪音--但代价是降低部分计算性能。
总的来说，风扇噪音可以承受，尤其是在中低转速时。它不会发出任何恼人的声音。缺点我们有时会注意到笔记本电脑内部发出噼里啪啦的电子声，这可能是固态硬盘发出的声音。

温度
在负载（压力测试、 Witcher 3测试）时，电脑的发热量并不高。我们偶尔会测到低于 40 摄氏度的数值。在日常使用中（办公、上网），其数值保持在绿色区域。
我们的极限压力测试场景（Prime95 和 Furmark 连续运行）检查了系统在满负荷情况下的稳定性。CPU 时钟从最初的 3.8 GHz (P)和 2.9 GHz (E)，在几秒钟内降至基本时钟以下。图形核心的运行频率约为 1,000 至 1,100 MHz。
(+) The maximum temperature on the upper side is 33.2 °C / 92 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 40.4 °C / 105 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 24.4 °C / 76 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 24.5 °C / 76.1 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 (+3.1 °C / 5.6 F).

立体声扬声器产生的声音总体上还不错。使用耳机或外置扬声器可以获得更好的音效体验。

耗电量
在笔记本电脑的功耗方面，我们没有发现任何异常。由于对 CPU 进行了节流，其功耗在压力测试开始后几秒钟就下降了。在测试过程中，其功耗保持不变。 Witcher 3测试期间保持不变。电源功率（90 瓦）足够大。

运行时间
在我们的实际 WLAN 测试（通过脚本映射访问网站时的负载）中，这款 14 英寸设备的运行时间达到了 10:55 小时，这是一个不错的值。这款 ThinkPad L14 G4的续航时间明显更长。

评价 - 商务伴侣和休闲游戏玩家
办公和上网任务对于安装有 酷睿 i7-1355U和 32 GB 内存（双通道）组成的组合，办公和上网任务易如反掌。需要 GPU 的应用程序和游戏则可从 GeForce RTX 2050.高速的 1 TB SSD 可确保较短的加载时间。
华硕 ExpertBook B3 B3404CVF 是一款适用于公司、组织和教育机构的全面工作设备。
这款笔记本电脑重量适中（约 1.65 千克），运行时间长（WiFi 约 11 小时），便于携带。两个 USB-C 端口可轻松集成到现有的工作场所设置中。此外，它们还可用于为设备供电，并提供额外的扩展选项（显示器、基座、外置 GPU）。
作为一款配备专用 GPU 的紧凑型笔记本电脑，它的排放值尚可。其安装的 16:10 WUXGA 屏幕（IPS，14 英寸）只能提供有限的色彩空间覆盖范围，对比度仍低于目标值（> 1,000:1）。您可以选择华硕提供的更好的 500 尼特面板（WQXGA），它能覆盖 DCI-P3 色彩空间。
B3 之外的另一种选择是 联想 ThinkPad L14 G4.这款笔记本的运行时间更长，但性能却落后于 ExpertBook。L14 没有配备 Thunderbolt 4、USB 4 或 dGPU。
