Where is AMD?

Better than AMD = Better than competition ?

If Intel think like this, they will never win

Once again a larger battery

0.36W 就差唔多 :o)

possible? given that provide enough processing power

Medfield: Battery-Guzzler Edition

Now the bad news: the power budget is quite high.  The platform reportedly has a 2.6W TDP at idle and a maximum power consumption of 3.6W when playing 720P Flash video.  By launch the maximum power is intended to drop to 2.6W, while the idle is also likely to drop a fair bit.

Still, these numbers are pretty horrible if Intel hopes to squeeze Medfield on a smartphone.  Some quick "napkin math":

    An average smartphone battery is around 1600 mAh
    The output voltage is typically 3.7 V
    The total battery power is thus 5.92 Wh
    Thus the platform would last a bit over two hours at idle in a smartphone before dying

In other words there's no way Intel can hope to launch this chip in a smartphone.

It's disappointing to see Intel is still trailing so badly in power.  For example, a loaded Tegra 2 reportedly draws around 1 W, meaning that it could sip the aforementioned battery for around 6 hours before kicking the bucket.  Intel's chip is fast, but it appears to be a "battery-guzzler".

More troubling is the fact that these results come from a 32 nm part, where as NVIDIA and Qualcomm have 40 nm parts (Samsung is also at the 32 nm node).  In other words, that process advantage Intel is always talking about appears to be nonexistent here.

Intel's best hope power-wise is its 3D FinFET technology, which wil be introduced to Medfield sometime in the 2013-2014 window.  That will likely be the true test of Intel's fading hopes in the mobile space.  If Intel's 22 nm finFET transistor chip can't meet or beat ARM in power budget, it's game over.

Still want to argue in power consumption front?

I just know playing a HD movie will doom Intel.

That's why AMD is not "fighting" it yet
They are NOT Ready

in fact this is a good move
just Intel and AMD invest too little in low-power computing
