The Galaxy Note 3 can support the Exynos 5 Octa 5410 silicon that was pegged for the Samsung Galaxy S4, so we'd expect the Galaxy Round to be just as flexible if it catches on with consumers.

In terms of software, expect to find Android 4.3 on all three phones.

Samsung Galaxy Round vs Galaxy S4 vs Galaxy Note 3 - Storage

Where the Galaxy Note 3 and the Galaxy S4 are available in 16, 32 or 64GB capacities, the Samsung Galaxy Round comes in a take-it-or-leave-it 32GB option.

That said, it features the same microSD slot as the other two Samsung devices, enabling the storage to be boosted to as much as 96GB with the addition of a 64GB memory card.

Samsung Galaxy Round vs Galaxy S4 vs Galaxy Note 3 - Battery life

As far as battery life is concerned, the Galaxy Round seems to feature a smaller 2800mAh battery, compared to the 3200 mAh cell in the Galaxy Note 3. This is obviously a disadvantage of the new curvy design.

That said, the Galaxy Note 3 didn't gobble up battery life as expected, especially considering its 5.7-inch display. The Galaxy S4 hides a 2600mAh Li-Ion pack.

So performance should be similar - Samsung rates the Note 3 with a standby time of 420 hours and a talktime of 21 hours. Use the Round for email, web browsing, music playback and all the other things that a smartphone is capable of doing, and you'll easily get a day's use on a single charge.

Samsung Galaxy Round vs Galaxy S4 vs Galaxy Note 3 - Early verdict

Far from being a new super-phone, the Samsung Galaxy Round is essentially a curved-screen version of the Galaxy Note 3. Bar LTA-A and 14g of weight loss, the two tablet-phones are almost identical, differentiated by the Round's flexible screen and the tilt functionality that it enables.

The screen itself isn't any better (or worse) than existing displays and it's hard to see the populist value in the new design.

If Samsung had debuted a truly flexible display, we'd be clamoring to own one. As is, the Galaxy Round is hardly going to change the game.
