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.

This is what should have been done by Intel:

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. ...
The A15 is a far more modern design, also out of order but much wider than A9. I fully expect that something A15-class can outperform Medfield, especially if the former is in a dual-core configuration. Krait falls under the A15-class umbrella so I believe Medfield has the potential to lose its CPU performance advantage within a couple of quarters.

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?

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

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果堆全部non-HK/MG 40nm, 即使係22nm FinFET, 對住都會係HK/MG 28nm

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.

btw, 就算出都太遲喇, 好多c9已經比左5K野samsung 買i9100,note等等,
你依家出返同一個功能的野有咩用??

A15係3-issue, superscalar, Out-Of-Order
A9係2-issue, superscalar, in-order
你話效能會唔會差唔多

Ti唔會show NV, power management已經無得比
Qualcomm一日重有baseband一日都係用最少external chip果間
Samsung...
