Huawei launched three new smartphones at the CES 2013, including the 6.1-inch Ascend Mate which is touted as the "world's largest smartphone." Huawei also took the wraps off its flagship Ascend D2 smartphone.

Both the smartphones physically resemble each other and seem like mirror images, barring the size difference, and promise to create quite a stir post release.

We take a look at what sets the Android-powered Ascend Mate and Ascend D2 smartphones apart, the key differences that make them individualistic.

Processor

Under the hood, both the smartphones packs in processors that clock the same and seem equally powerful on paper. However, considering that the Ascend Mate's processor will power a bigger device, the Ascend D2 could well be the winner in this area.

The Ascend Mate has a 1.5 GHz Hi-Silicon quad-core processor, whereas the Ascend D2 has a 1.5 GHz quad-core Hi-Silicon K3V2 + Balong V7R1 processor.

Display

The screen size of both the phones is the most prominent of all the differences, but if you thought size ensured better resolution then be prepared to be surprised. The Ascend Mate has a 6.1-inch HD IPS+ LCD touchscreen with Corning Gorilla glass. By contrast, the Ascend D2 has a puny 5-inch Super Retina fast response IPS display with Cornilla Gorilla Glass.

However, the Ascend D2 has a pixel resolution of 1920 x 1080 versus the 1280 x 720 pixels resolution of the Ascend Mate. What's more, the Ascend D2 has a pixel density of 443 pixels per inch (ppi), compared to the 241 ppi of its bigger sibling.

USP

Another feature that sets the phones apart is that the Ascend Mate has the "Magic Touch," which provides "enhanced screen responsiveness even with gloves." This feature is notably absent in the Ascend D2; however, it has its own USP i.e. it is both water and dust proof unlike the Ascend Mate.

Form Factor

The obvious and most noticeable difference in the two Huawei smartphones is but of course the size. The Ascend Mate measures 6.44 x 3.37 x 0.39 inches, whereas the Ascend D2 measures 5.51 x 2.80 x 0.37 inches, which means that the former is taller, wider and fractionally thicker than the latter.

Weight-wise, at 6.98oz, the Ascend Mate (as expected) is much heavier than the Ascend D2 which weighs 5.99oz. The weight is attributed to its bigger size and heavier battery.

Storage and Memory

The Ascend D2 steals the show yet again with the on-board storage and memory options, making it a better bet for all your download and gaming needs.

It will be available in 32GB whereas the Ascend Mate will come in 16GB. Furthermore, the Ascend D2 has double the RAM of the Ascend Mate - 2GB versus 1GB.

Camera

Camera-wise, the Ascend Mate's 8-megapixel primary camera is no match for the Ascend D2's 13-megapixel one. The Ascend D2's camera also has a BSI sensor unlike the Ascend Mate's.

Moreover, the Ascend D2 packs in a better front-facing snapper as well. It has a 1.3-megapixel secondary camera whereas the Ascend Mate has a 1 megapixel one.

Battery

Another key difference between the two phones is the battery size and standby time supported.

The Ascend Mate packs in a 4050mAh battery to power the colossal 6.1-inch phablet, which supports up to nine days of standby time on 3G. On the other hand, a smaller 3000mAh battery fuels the Ascend D2 and offers a standby time of six days.

In conclusion, Ascend D2 scores in camera, display (ppi), processor speed, and storage and memory segments, whereas Ascend Mate scores in display (size) and battery segments.
