[中央處理器] Intel big little?

點解intel學唔到arm 咁玩big.little?
atom加core,正常時就行atom一開部份program就行core?

因為intel core i3/i5/i7 idle下耗電量不比atom差幾遠

但係運作情況下差距應該唔細吧?

Atom同U版CPU Performance per watt相差唔遠:https://www.cpubenchmark.net/power_performance.html#id2

你可以咁諗
Core m 架構上同Desktop CPU一樣,
所以Desktop以低頻低壓運作已經可以做到little效果

desktop當然唔需要big little,我係想用係ultrabook到core m加core i/atom 加core i
   ,咁電池可以做細,插AC又有好performance

回覆 6# weirdoxlee
你要Mac OS同Window改寫......難D
如果你話好似電話在閑置時停用部分CPU會易D

都話m同i一樣
而m同atom performance per watt差唔多
所以冇乜作為

intel's version's called big PROFIT, LITTLE improvement


Fact: when the power envelope allows you to scale from 1 to 3GHz, why bother a less efficient design?

intel洗鬼搞咁多野咩,本身架構做得好就唔洗再哂料堆big little
