Windows Skylake Convertible / 2-in-1

小而优。 m3版本的Spectre x2 12在899欧元(约6640人民币)的价位上提供了LTE模组。这台设备能否提供优秀的性能,还是会像m7版本一样会有降频问题呢?

Cons

- 无工艺缺陷
- 处理器表现比我们预想略低
- 尽管搭配了酷睿m3但性能较弱

搭配m7处理器的姊妹机型的最大问题在m3机型上也可以找到:在我们的实际测试中它的续航时间只有6个小时。幸运的是,我们的测试机搭配了LTE模组,它为用户带来了很多额外选择。

m3机型的性能比我们预期略低,比如Surface Pro 4搭载的相同处理器性能就稍高一筹。Spectre x2 12的m3和m7机型是同类变形本机型中性能最弱的两款(系统性能和处理器运算)。在一对一比较中,这两个机型十分接近,也各有优势:m7机型在单核测试中遥遥领先,而m3机型的LiteOn固态硬盘提供了更高的速度。

惠普Spectre x2 12-a001ng (P0T72EA)表现让人出乎意料:在一些卖家处它的售价只有899欧元(约6633人民币)。在这个价位上,它显然是个不错的选择,十分值得推荐。不过在1000欧元(约7378人民币)的价位上,它可能会有些不够诱人。

另一方面,许多同类机型售价1250-1300欧元(约9258人民币到9628人民币)。在定价800欧元(约5925人民币)的Acer Aspire Switch 12 Alpha(水冷,酷睿i5 6200U和3K屏幕)上市后它应该会有所折扣。

Alpha和我们的测试机面向相同的用户群体,需要性能和便携兼顾,可以适应日常和商务用途。

这类产品的市场十分引人侧目,请参见我们的变形本Top 10排行。联想IdeaPad Miix 700Surface Pro 4和华为MateBook(正在测试中)都可以作为备选机型。
