This is what should have been done by Intel:

引用:

Although the CPU core is mated to a 512KB L2 cache, there's a separate 256KB low power SRAM that runs on its own voltage plane. This ULP SRAM holds CPU state and data from the L2 cache when the CPU is power gated in the deepest sleep state. The reasoning for the separate voltage plane is simple. Intel's architects found that the minimum voltage for the core was limited by Vmin for the ULP SRAM. By putting the two on separate voltage planes it allowed Intel to bring the CPU core down to a lower minimum power state as Vmin for the L2 is higher than it is for the CPU core itself. The downside to multiple power islands is an increase in die area.

出貨先講LA  

出到既

出到果陣上面果個表已經out左半年 :o)

TSMC / GF 28nm都出唔到大貨

I just knew Intel and its x86 will rule.

其實仲有一樣野係未知既 (price)
斷估就算佢勁過Tegra 2一大截, 都唔會同佢鬥價 (us$1x)

Medfield 係 X86?

玩贏Ti/Qualcomm/Samsung已經夠啦.

Ti有難度...

今次班ARM大帝大檸樂.
22nm要上就上,省電更上一層樓,而且貨要幾多有幾多,對班手機生產商都咪話唔吸引.

NV呢D賤價王我怕變左AMD,頭啖湯都無得食. ...

ARM Cortex A15行out of order + high freq
篇文都話, 舊年出會係壓倒性, 但係今年有A15, 邊個嬴都仲未知

不過最少Intel會有入場券先

Though Intel dished something interesting finally, the war has yet to be over.
How long would it take for Intel to make a follow up?

At least 2013 with OoO / 22nm chip

btw 唔睇好 因為兼容問題

Android係VM on linux

Intel下一代應該會出OOO "Atom"啦掛.......
28nm v.s. 32nm,定係28nm v.s. 22nm都無人知,唔使輸點都有機會.

而家Intel quote果堆chip全部non-HK/MG 40nm, 即使係22nm FinFET, 對住既都會係HK/MG 28nm A15

即係40對32,28對22.
A15雙核先追到Atom單核(同頻),22一出應該Keep到掛.

A15會出quad wor

A9都有quad (Tegra 3)
你唔係期望A15得dual下話

電話應該無咁快Quad掛,Tablet果邊Atom雙核迎戰.

唔太睇好4-thread的phone CPU

qcmadness

phone有4-thread都好難用
其實以VM的方法, 更加會係2-thread係最好

所以Atom單核玩贏雙核A15就夠.
Tablet果邊玩Dual core Atom.

大家都知呢個機會唔大

正如你可以期望Atom打嬴Bulldozer / K10

Android.......
有Native唔玩玩VM,浪費CPU資源,難怪窒到嘔.
唔知Intel既Brutal force能唔能夠解開Android窒機魔咒.

唔會

玩VM就係為mutli-platform (ARM / x86)
