How do the freshly released Samsung Galaxy Tab S2 and the rumored Microsoft Surface Pro 4 and the Apple iPad Air 3 compare to one another? 

Samsung launched the Galaxy Tab S2 on Sept. 3. It is powered by the company's own Exynos 5433 processor that is paired with a Mali-T760 MP6. It features 3 GB of RAM and has a Super AMOLED display that offers 2K Full HD resolution for both its 8-inch and 9.7-inch variants. 

As for its camera, the Tab S2 has an 8 MP rear camera and a 2.1 MP front camera. It's home button also serves as a fingerprint scanner and the device supports the use of a microSDXC memory card that allows for storage expansion of up to 128 GB. 

Meanwhile, the Microsoft Surface Pro is reportedly going to sport a new Intel Skylake chipset and its storage may go up to 1 TB, Tech Radar reports. According to WCCFTech, the device will come in 13-inch and 14-inch variants, both supporting 2160 x 1440 pixel resolution. 

No information about the Surface Pro 4's camera has been released, although many speculate that it may feature a RealSense 3D Camera and even an IRS scanner. 

Apple's iPad Air 3, on the other hand, may sport the A9 chip, according to MacWorld, or possibly its successor. The report states that Apple might refrain from just putting in the most powerful processor to elevate battery life. 

The iPad Air 3 may retain the same 12 MP rear camera now featured on the iPhone 6s and 6s Plus or it may use the 8 MP shooter featured on the iPad Air 2. It is also stated that the screen may keep up with the iPhone 6 and feature a Retina HD display. 

As both the iPad Air 3 and Microsoft Surface Pro 4 have yet to be released, this comparison thus far is hypothetical. However, if the specs turn out to be accurate, then the Surface Pro 4 may be the most powerful device among all three choices. But this would also mean it would be the most expensive, with the Galaxy Tab S2 sitting in the middle ground.
