MagyarRobo and Kala TW220 二合一 OLED 平板电脑评测：超越微软 Surface Go 3
TW220 是美籍华人公司 Robo and Kala 最新推出的 Windows 11 旗舰平板电脑。它是极少数采用 ARM SoC 的 Windows 平板电脑之一，更不用说采用 高通骁龙 8cx Gen 3集成 Adreno 690 图形处理器。因此，它直接与微软 Surface 系列产品竞争，包括最近推出的 Surface Pro 9 ARM采用了完全相同的高通处理器。
除了不常见的 SoC 之外，它的规格也像一款高端平板电脑，包括 16:10 2560 x 1600 OLED 触摸屏（98% DCI-P3 色彩）、16 GB LPDDR4X 内存、512 GB NVMe 固态硬盘和可拆卸键盘底座，售价 599 美元，比一般采用酷睿处理器的 Surface Pro 便宜数百美元。

案例 - 强烈的第一印象
铝制机身坚固耐用，给人留下了深刻的第一印象，因为它比 Surface Pro 更薄、更轻，边框也更窄。键盘底座也很坚固，但其连接插针太容易从平板电脑上脱落。
平板电脑本身重 712 克，键盘底座重 350 克，总重 1.06 千克。它比大多数甚至所有 Surface 型号都要轻，包括较小的Surface Go 3.
连接性
两个 USB-C 端口分别支持 DisplayPort 和充电。我们能够以 8 位色深输出最高 4K 和 60 Hz 的图像。没有耳机插孔。
交流
高通 WCN685x 是 Wi-Fi 6 和 Wi-Fi 6E 连接的标准配置。在与华硕 AXE11000 6 GHz 网络配对时，我们没有遇到任何问题。
网络摄像头
TW220 的网络摄像头分辨率为 1300 万像素，比以下两款产品的网络摄像头分辨率都要高 Surface Pro 9(10 MP）和 Surface Go 3(800 万像素）都要高。内置的红外摄像头支持 Windows Hello，但没有隐私快门。
配件和保修
零售包装盒包括背光可移动键盘底座和 4096 级压力智能笔。键盘底座有自己的内置电池，可以通过蓝牙无线连接到平板电脑，也可以通过连接插针物理连接到平板电脑。键盘底座没有集成任何端口，因此只能在与平板电脑物理连接时才能充电。
制造商提供标准的一年有限保修服务。
输入设备
键盘
平板电脑的可拆卸键盘几乎总是不如传统笔记本电脑的键盘。不过，TW220 的键盘其实还不错。按键反馈均匀、清晰，1.3 毫米的键程是标准配置。遗憾的是，按键感觉有些僵硬，手指需要花更大的力气才能按下并记录输入。
触摸板
点击板的尺寸为 11 x 6.5 厘米，比 Surface Pro 键盘上 10.2 x 5.8 厘米的点击板要大。点击时的反馈较浅，但比大多数笔记本电脑更有力。不过，咔哒声随后会变得尖锐而响亮。
显示屏 - OLED
TW220 是我们数据库中第一款采用夏普 RM69380 OLED 面板的设备，与之形成鲜明对比的是 LG 飞利浦 LP129WT2 或京东方 NV105WAM IPS 面板。Surface Pro 9或 Surface Go 3 分别采用的是 LG Philips LP129WT2 或 BOE NV105WAM IPS 面板。与 IPS 相比，OLED 具有固有的优势，包括更快的黑白响应时间以减少重影、更深的黑阶、更宽的色彩范围和更好的亮度均匀性。

尽管显示屏是高质量的 OLED 面板，但并没有经过预校准。它的目标色温是 P3，但过冷的色温意味着在饱和度较低时色彩不准确，正如我们下面的 CalMAN 测量结果所示。

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 60.6 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 60.6 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 60.6 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17903 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
在所有亮度级别（包括 100% 设置）下都会出现闪烁。我们能检测到 60 Hz 的闪烁，这与大多数其他配备 OLED 显示屏的平板电脑、笔记本电脑或智能手机的情况类似。
实际上，Robo 和 Kala 的显示屏比 Surface Pro 9 或 Surface Go 3 的显示屏亮度要高出 25% 到 35%。不过，还是建议在阴凉处工作，以减少眩光，最大限度地提高色彩鲜艳度。
性能 - 多线程情况下比酷睿 i3 更快
测试条件
在运行以下基准测试之前，我们将 Windows 设置为性能模式。值得注意的是，许多应用程序都无法在 Windows ARM 上启动，包括我们常用的许多基准测试应用程序。LatencyMon、PCMark 10、3DMark、i1Profiler、BaseMark、Geekbench 5.4、GPUScore Sacred Path、3DMark 06、HWiNFO 传感器读数和某些 Windows 批次文件只是我们在测试过程中遇到问题的部分应用程序。
处理器
原始多线程性能始终领先于三年前的酷睿 i5-1035G1而单线程工作负载则恰恰相反。4K 编码或 Blender 等高要求任务的运行速度比酷睿 i5 慢，这意味着高级用户仍应考虑使用酷睿 i7 微软 Surface Pro。至少 骁龙 8cx Gen 3要比速度慢得令人发指的 Surface Go 2.
在 Prime95 下运行时，CPU 时钟频率在最初几秒内会高达 2.7 GHz，几分钟后才会下降并稳定在 2.1 GHz。

系统性能
主观而言，Windows 11 在骁龙 SoC 上运行流畅，反应灵敏，测试过程中没有出现 BSOD。尽管如此，请记住大多数应用程序都是通过模拟运行的，因此出现不兼容的几率很高。
操作系统导航不如大多数Android 平板电脑流畅，部分原因是显示屏的刷新率为 60 Hz。如今，大多数平板电脑已经采用了刷新率更高的显示屏，如联想 P11 的 120 Hz 显示屏。 联想 P11.

耗电量
OLED 触摸屏明显更耗电，因为根据颜色和亮度设置的不同，它本身的功耗就高达 9 瓦。与 Surface 机型相比，它可能提供更深的色彩和更亮的背光，但用户需要为此付出更高的功耗。

Pros
Cons
评语：Surface Pro 和 Surface Go 之间的绝佳中间点
Robo and Kala TW220 的最大亮点在于其 OLED 触摸屏、不错的 ARM 性能以及相对实惠的售价（铝制机身和键盘底座做工精良）。OLED 显示屏尤其有助于将 TW220 与竞争对手 Surface Pro 和 Surface Go 系列区分开来，是该机型的一大亮点。如果用户能够欣赏或利用 OLED 显示屏更宽广的色彩和更深邃的黑阶，就会发现 TW220 比其他大多数 Windows 平板电脑更有价值。
如果你能接受 Windows ARM 的限制，那么 Robo and Kala TW220 将是 Surface Go 3 甚至 Surface Pro 9 的经济实惠的替代品，如果你不需要英特尔酷睿 i7 的强大性能的话。
对于未来的型号，我们希望看到显示屏经过预校准，这样用户开箱即可享受到准确的 OLED 色彩。键盘连接插针可以更牢固一些，如果能提供更多的连接选项，包括 MicroSD 或 LTE/5G 选项，我们将不胜感激。ARM 处理器不可避免地存在某些兼容性问题，因此，采用英特尔酷睿处理器的替代机型可能会吸引更多感兴趣的买家。不过，对于浏览、收发电子邮件和流媒体等基本任务来说，TW220 是我们所见过的同价位最高效的 Windows 平板电脑之一，尤其是与较小的 Surface Go 系列相比.
