We're learning more and more about the internals on Samsung's new wearables which will be available on Friday. The Gear 2 and Gear 2 Neo are nothing running on Exynos chips. Those two are running on the Exynos 3250 chip, which has a dual-core 1GHz processor. This is a Samsung-made chip that was made specifically for lower-powered devices, like smart watches. It's the same processor that Samsung used in the Galaxy Gear, but they had to down-clock it to 800MHz so that they could achieve adequate battery life. While the Gear 2 and Gear 2 Neo both run on Tizen, Samsung was able to allow the processor to run at it's full clock speed without any issues.
Now the Gear Fit is running a completely different chip, which Sammobile is reporting is the STM32F439, which is a Cortex-M4 based solution that is more of a micro controller rather than a full fledged processor. With the max clock speed of 180MHz. So it's obviously a lot less powerful than what's inside the Gear 2 and Gear 2 Neo. But because of this, it uses such a small amount of energy, which means they can put in a smaller battery and it'll still last a long time. According to Samsung, the Gear Fit can last about 5 days on a charge. Which I think is plenty, since you could charge it every night, but being able to get a bit more than a day or two out of it means you're not out of luck if you forget to charge your Gear Fit that night.
The Gear Fit and Gear 2 Neo are available for pre-order now for $199, with the Gear 2 at $299. All three will be available on Friday, April 11th, from carriers like AT&T, Sprint, Verizon and T-Mobile as well as retailers like Amazon.
