Samsung Electronics Co. Ltd. on Thursday teased its upcoming Gear 2 smartwatch – to date known by its codename “Orbis” – due for release at IFA 2015, September 4 – 9. Apart from a series of images, the company revealed nothing about the smartwatch, but as expected, it is round instead of rectangular like its predecessor.

Love it or hate it, since its release the Apple Watch has transformed the smartwatch market and has become the yardstick against which every existing and new smartwatch will be measured for years to come. While we know almost everything there is to know about the Apple Watch, we only have rumors to go on for the Samsung Gear 2. Nevertheless, what follows is a comparison of the two, based on what we know so far.

Apple Watch

Dimensions

Apple Watch comes in two case sizes: 38mm and 42mm. Both of which can be set up to work on either the left or right wrist.

Display

The retina touchscreen display features Force Touch and sapphire glass or Ion-X glass cover, depending on model. Display sizes: 38mm at 340×272 pixels; 42mm at 390×312 pixels.

Chipset

Apple S1 computer-on-a-chip, of which few details are provided. Here’s what Wikipedia has to say of the System-in-Package chip:

“It uses a customized application processor that together with memory, storage and support processors for wireless connectivity, sensors and I/O comprise a complete computer in a single package. This package is said to be filled with resin for durability. Very little is known about it, in any respect, but Chipworks believes that they have at least identified the processor handling the Wi-Fi and Bluetooth as a Broadcom BCM4334. It would be the medium size processor in the center at the top of the illustration below.”

Navigation

Capacitive touch (tap, swipe), Force touch (press) Digital crown (scroll, zoom, home, time, accessibility, Siri), Button (Friends, Apple Pay, power).

Storage

8GB internal memory (with an estimated 2GB of internal storage for music and 75MB of storage for photos).

Sensors

Heart rate sensor, accelerometer, ambient light and gyroscope.

On the back of the case, a ceramic cover with sapphire lenses protects a specially designed sensor that uses infrared and visible-light LEDs and photodiodes to detect your heart rate during workouts and when using the heart rate Glance.

Connectivity

Wi‑Fi (802.11b/g/n 2.4GHz) and Bluetooth 4.0 connectivity and GPS

Battery

18 hours of mixed usage, which equates to 90 notifications, 90 time checks, 45 minutes of app use and a 30-minute workout session with music streaming via Bluetooth. The battery is replaceable. Type unknown.

Apple says it will take 90 minutes to reach an 80% charge on the battery from zero percent and 2.5 hours to reach 100 percent.

OS

Apple’s watchOS 1.0.1

Samsung Gear 2

Dimensions

Unknown, but likely to be feature a 42mm diameter casing.

Display

Super AMOLED display with a 360×360 pixels resolution at 305ppi.

Chipset

Samsung’s Exynos 3472 dual-core processor clocked at 1.2 GHz, the Mali-400 MP4 GPU clocked at 450 MHz and 768 MB of RAM.

Navigation

Release notes from a Gear A software development kit (SDK) released in May revealed that the smartwatch will feature a “rotating bezel” similar to those found on conventional watches. The same SDK also pointed at a digital crown, much like the one found on the Apple Watch. Together, the bezel and digital crown will allow users to navigate and interact with the user interface.

Storage

4GB of onboard storage, with no detail on how that storage is allocated – if at all.

Sensors

A built-in GPS, accelerometer, gyro, barometer and heart rate sensors.

Connectivity

Bluetooth 4.1, 802.11 b/g/n Wi-Fi standards and Wi-Fi Direct.

Battery

250 mAh battery, no detail on expected battery life.

OS

Samsung’s Tizen operating system.
