Samsung announces the Exynos 7270, the first wearable SoC built on a 14nm process

Samsung has announced a new chip for wearable devices. Called the Exynos 7 Dual 7270, this is the first application processor for wearables that’s built on a 14nm process. 

Samsung started making smartphone SoCs using its 14nm manufacturing process back in 2015. The Exynos 7420, the chipset that powered the international versions of the Samsung Galaxy S6, S6 edge, and Galaxy Note 5, was the first Samsung chip that the company manufactured using the technology, but now Samsung is ready to utilize its state-of-the-art 14nm foundries to make chips for wearables as well. 

Back to the Exynos 7270, the wearable chip integrates two ARM Cortex A53 cores, which are designed to balance performance and power efficiency. Since the chip will be made using the 14nm node technology, Samsung says that the CPU will be about 20% more energy efficient compared to similar chips built on 28nm. 

Interestingly, the Samsung Exynos 7270 will also integrate an LTE Cat.4 modem, a feat that will allow wearables based on the chip to transfer data over carrier networks without going through a paired device. The Exynos 7270 will also integrate WiFi, Bluetooth, and FM radios, thus completing the essentials communications package. 

Another thing to note about the Samsung Exynos 7270 is that the AP will integrate the CPU, the radios, the DRAM, and the NAND flash memory chips in a single piece of silicone. Samsung says that the solution saves up about 30% of the total height, a feat that will allow wearable makers to design thinner wearables without sacrificing performance or power efficiency.

Samsung did not announce when the first wearables based on the Exynos 7270 will hit the market, but the company said that interested device manufacturers can already get their hands on a reference platform which consists out of the chip, an NFC chip, and various sensors. This way, device makers can already start work on their upcoming devices before the chip is ready to roll out. 

In closing, we’d like to note that, while Samsung did not mention it, we suspect that the Exynos 7270 will be at the heart of the upcoming Samsung Gear S3 smartwatch, a wearable that’s expected to launch as early as later this month.

Will it explode? There. I asked it for you. Dont be shy asking these, its your life at risk. And that is something Samsung can't replace.

Last time I heard it was a battery issue, not a SoC issue.

I would have expected halving the nanometer process would have yielded much higher efficiency not quite 100% more efficient but certainly more than 20%

20% more energy efficient and 30% smaller is a good news but why they wanna make a thinner watch instead of bigger battery?

They could make a thinner watch and have a bigger battery.

So it going to consume 25% more power than 28nm Cotex-A32 at same clock speed. If somebody decide to manufacture Cortex-A32 with Global Foundries' 22nm FDSOI it going to consume 75% less power and the cost will be the same with 28nm.

Not a good chip. A53 are midrange chips. A57+A53 would be super.

That would be true if it was intended to power smartphones. This chip is more than good enough for wearables which don't need as much processing power as smartphones and have to utilize energy sparingly because they have much smaller batteries.

Another weak processor! Why do they attempt to save about $15 per processor rather than put the best in their phones. Samsung which market do you want? Low end or high end? They are confused...

Yes, A72 has about twice the performance of an A53... The cost is not the problem here, the problem is battery consumption...! But I'd sure love to see a successor of aging A53. More powerful yet as efficient as The Cortex-A7... G'Day!

That's for wearables not for phones. It probably is unnecessarily expensive and powerful for the job.

Some people don't get that not every chip is made to power phones. This chip is designed for wearables. As such, it doesn't need as much processing power as those needed for phones, and the focus is on energy efficiency.

Did you even read the title? ..honestly...
