你英语好不好?我转贴的英语红字已经说明T4在续航测试中,伴核根本没有发挥作用,一直是四核A15在工作。
自己贴的自己仔细看看,别只看红字部分,下面写的很清楚了
Unlike under Android, there’s no hot plugging of CPU cores under Windows RT – there are always four Cortex A15s presented to the OS/scheduler, regardless of whether or not the companion core is active. Microsoft tells me the companion core is used on Surface 2 (unlike its predecessor), however specifics are tough to come by. Microsoft claims the companion core is used during full screen video playback.

伴核在surfacce2被使用了,不像前任(surface1),而且微软声称在视频播放时候,伴核被使用了,写的够清楚了。
这样的好处就是逻辑可以不跑在四核a15上,可以保持所有核心的频率降低(还是那个同步cpu的弊病,不能单个cpu跑高频所以只能把逻辑扔开),即使如此,省电也并不比bt好。 |
