never thought i'd see a 90nm cpu be considered the most energy efficient in 22/28nm era

true but considering it uses a 1/3 of the power of a 8bit chip is sweet.

Home appliances? I dread the days when our microwaves, toasters and coffee makers have lan ports or wifi cards and operating systems.

makes you wonder what a 22nm chip like this will be like. Maybe it will be able to run on less than 0.1w of power.

Well, by strict definition, everything with a chip has an OS... And well... Samsung already has several appliances with WiFi

Cheers!

Why 90nm ? why not less?

Hail to the era of power efficiency...

I'd bet $10 your microwave is running unix right now.

90nm probably costs less to make?

Since when is Amps a measure of energy? Energy is measured in JULES. If you're gonna give amps, at least give voltage too.

Efficiency comes down to how much electricity is turned into usable energy. Just because something uses nearly 0 energy won't necessarily make it efficient.

I have to disagree. It all depends on the appliance. For example, notifications from items like shared washing machines and laundry dryers would kick a** in an apartment setting especially. *Bing* Your dryer is done... *Bing* The dryer is now free *Bing* The rinse cycle has started... etc etc etc.

I love when people make mistakes while angrily pointing out others' mistakes. I think you meant "joules".

"consumes only one third of 8-bit and 16-bit processors that are used in the application field targeted by the processor"


I think something's missing ... consumers only one third the power of 8-bit ...

consumes*

2) I need to turn off auto-correct

So how does this translate to smartphone usage? Don't tell me that i still have to charge it everyday...

It takes nine microwatts per megahertz, I think it would be under your 0.1W figure most of the time.

As for 22nm, maybe with a die this small they'd have problems with power gating and whatnot to stop leakage from a smaller process, just a guess. Otherwise I can't think why something they want to draw the least possible power would be on such an old process, even 65nm would have higher yields and still be very attainable.

Even a dumbphone (err, featurephone) would have a more powerful processor than this, its not made for smartphones and I doubt it could run a modern OS, this is for appliances that just need to send and receive simple information like power draw of other appliances.

I sure hope they put a "Mute" button

Finally, we will see +48 hour battery life again in our phones soon.

Given that most people don't have even the slightest clue what a "joule" is, the use of amps in this case is acceptable as it doesn't send people off to google to research wtf a "joule" is, yet still gets the point across.

Good catch... or maybe it's a zombie. ; )
