Samsung unveiled its latest set of wearables at MWC 2014 in February, but at launch, the Korean tech giant didn't provide the exact details regarding the specifications of the devices.For example, it said that the Gear 2 and Gear 2 Neo smartwatches were powered by a 1GHz processor that remained unnamed. Now, SamMobile provide us with the missing bits of information.
First off, the Gear 2 has been showed to be running on the Exynos 3250 chip with a dual-core processor running at 1GHz. So there’s no Snapdragon goodness under the hood and by the looks of things, that has been reserved for Android Wear devices.
The Exynos 3250 comes from Samsung’s own garden and has been specially developed for low-power devices such as the smartwatches. In the original Galaxy Gear, Samsung had to use an 800MHz processor in order to keep battery life at decent levels.
So it seems the Gear 2 smartwatch is an in-house endeavor running on Samsung’s own chip architecture and Tizen OS platform.
Moving on, the Gear Fit is powered by a rather dull ST-Microelectronics chip, which is reportedly based on the STM32F439 chip, a Cortex-M4-based solution that resembles more a microcontroller and not a full-fledged processor.
The chip may not be that powerful, but the upside of this is that it’s extremely low on energy, allowing the Gear Fit to last up to five days on a single charge.
