Surface Pro 4杀手？惠普Spectre x2平板电脑评测

北京时间12月2日消息，科技网站LaptopMag今日刊文称，惠普最近发布了全新的Spectre x2混合型平板电脑，其直接对手就是微软的Surface Pro 4。在容量和内存保持一致的情况下，Spectre x2的起售价为800美元，比Surface Pro 4便宜200美元，性价比极高。售价中还包括键盘的价格，而Surface Pro 4的键盘需单独购买（130美元）。除了超高性价比之外，这款平板还有那些特点呢？请看下面的详细评测。

1、外观设计

▲Spectre x2外观

Spectre x2采用2合1混合平板设计，机身融合黑、银、灰三种色调，商务气息浓厚。机身背部采用拉丝金属材质，机身四角运用弧形过渡，整体手感舒适。标配键盘通过惠普独家研发的磁力技术与屏幕进行连接，键盘底部还配有金属底板，保证按键按下时键盘不会弯曲，即使放在腿上打字也不用担心变弯。平板背部配有金属支架，与Surface Pro的支架不同，它采用的是U形支架，并且内嵌于平板背部，滑动开关即可弹出，但在打开时稍感僵硬，优点是可变换角度更大。

在不连接键盘时，其机身尺寸为11.81 x 8.23 x 0.31英寸，重1.87磅（848克）；连接键盘后，机身尺寸变为11.81 x 8.23 x 0.52英寸，重2.68磅（1215克），比Surface Pro 4更大、更重，但是相对传统的2合1平板――比如东芝的Satellite Radius 12和联想的Yoga900，它已经足够轻薄了。

2、键盘和手写笔

▲Spectre x2键盘

Spectre x2配有可拆卸的背光键盘，也可以将其翻转垫在平板下面。笔者在进行打字测试时，每分钟可输入82词，相比平均75-80词/分钟的速度，这款键盘的打字体验还是很棒的。可能很多人会抱怨它的键程只有1.36mm，略低于惠普推荐的1.5mm键程，但是其干脆利落的敲击体验可以让你忽略缩短的键程。在这款键盘上还配备了宽大的触控板，尺寸为4.75 x 2.25英寸，表面采用拉丝金属材质，触感异常顺滑。该触控板还支持多重手势操作，比如双指滚动页面等。

▲Spectre x2手写笔

与键盘不同，Spectre x2的手写笔需要单独购买，售价50美元（约320元）。这款手写笔支持2048压力感受级，在笔身中部有两枚按键，电源键位于笔的顶端。因为Spectre x2采用的是和冠公司的触控笔技术，所以如果你嫌官方手写笔太贵，完全可以使用第三方触控笔。

3、屏幕

▲Spectre x2屏幕

Spectre x2采用12英寸屏幕，分辨率为1920 x 1080，显示效果清晰锐利，但是相比同类产品，其色彩表现不够鲜艳和生动。在观看《星球大战：原力觉醒》时，Jakku星球上的细节尽收眼底，但是整体红色调偏淡，而沙漠和天空的颜色则饱和度过高。使用光度计测量时，其屏幕亮度为322尼特，超过了Yoga 900（282尼特），但仍然不敌Satellite Radius 12（338尼特）和Surface Pro 4（382尼特）。色彩精度上，Spectre x2的Delta-E数值为0.71（数值越接近0则精度越高），远远落后于Surface Pro 4（0.4）。

▲Spectre x2主屏

该屏幕的最大问题还是色域范围。在我们的测试中，其sRGB色域覆盖率仅为71.9%，相比竞争对手93-100%的色域覆盖率，这块屏幕的变现还有很大差距。

4、音效和发热

Spectre x2配有两个Bang & Olufsen扬声器，在键盘里还藏着两个扬声器。实际体验时，其音效让人满意，尤其是中音比较饱满，低音区表现也很不错。在发热测试中，笔者连续用Hulu在线播放高清视频15分钟，Spectre x2的平均温度保持在35℃，机身背部的最高温度为35.5℃。

5、扩展接口

▲Spectre x2接口

Spectre x2没有采用常规的Type-A或microUSB接口，而是配备两个USB Type-C接口，虽然正反两面都可以插，但在连接普通打印机或手机时难免有些不便，好在惠普随机赠送了接口转换器。除此之外，该平板还配有microSD卡槽，允许存储卡扩展；配有microSIM卡槽，支持4G LTE网络，通过USB C接口还是可以向外输出1080p视频。不足是开启SIM卡槽时需要一根非常细的针，对于经常换卡的用户来说可能有些不便。

6、相机

▲Spectre x2前置摄像头

Spectre x2配有3颗摄像头：前置500万像素摄像头，后置800万像素主摄像头+英特尔RealSense 3D摄像头。其前置摄像头表现优秀：室内自拍时，在保证曝光度的前提下，笔者的面部、背后的墙壁以及电视等细节表现丰富，相比之下，其后置摄像头在拍摄时则会出现明显的曝光不足。

▲RealSense 3D摄像头

平板背部的RealSense 3D摄像头采用实感技术，可以对不同物体进行3D扫描。可惜目前支持的App很少，只有一款名叫itSeez3D的软件，用它可以扫描面部和身体，但是很不好用。在面部识别方面，它的表现还是不错的，可以对不同形状的物体进行辨别。

7、性能表现和电池续航

▲Spectre x2性能

Core M7-6Y75处理器、8GB内存、256GB固态硬盘，对于一款800美元的平板来讲，Spectre x2的配置可谓强劲。使用体验上，笔者连续开启10个Chrome网页，同时在线观看1080p Youtube视频，完全不会感到卡顿。Geekbench 3的跑分成绩为5814，不敌Core i5版Surface Pro 4 (6,811)和Core i7版Yoga 900 (6,264)，但二者价格高达1429美元和1399美元，所以相比而言这样的成绩还算不错。其固态硬盘的读取速度约为149MBps。

▲Spectre x2图形处理

图形处理方面，该机搭载Intel HD Graphics 515显卡，运行《炉石传说》这样的休闲游戏还是游刃有余的，但是在玩魔兽世界时，分辨率设置为1920 x 1080，其帧率保持在41fps，只能说勉强能玩。3DMark跑分成绩为668，相比Surface Pro 4 (843)和Yoga 900 (840)还是差了一截。

电池续航是Spectre x2的致命伤。在进行标准电池测试时，屏幕亮度保持100尼特，连接WiFi状态下连续上网，x2只能维持6个半小时，而普通超极本的平均成绩为8小时10分钟。

9、总结

▲惠普Spectre x2平板电脑

Spectre x2的起步价为800美元（约5100元），高配版1400美元（约8900元），相比Surface Pro 4而言性价比更高。外观设计上成熟稳重，做工坚实可靠，键盘体验尚佳，尤其是支持SIM卡，还可以使用4G网络。遗憾的是电池续航和屏幕表现不够理想，除此之外，Spectre x2可以说是一款非常理想的2合1平板电脑。
