Motorola Mobility is supposedly set to unveil its much-anticipated Atrix HD, as reportedly revealed on the company website. However, the website page, which divulged almost all details on the upcoming smartphone listed as MB886, is longer available.

Codenamed as "Dinara", the device features a 4.5-inch ColorBoost display with 720p resolution, a 1.5GHz dual-core processor, 8GB of built-in storage, 1GB of RAM, an 8-megapixel rear-facing camera, and a 1.3-megapixel camera on the front. The smartphone will head to AT&T according to the carrier's logo found in front of the pictured handset. Amongst other specifications that the forthcoming device will include are Android 4.0 Ice Cream Sandwich OS, 4G LTE connectivity as well as microSD card support.

The phone will also feature a Gorilla Glass-enforced screen with Kevlar-backing for durability, and a 1,780 mAh battery will be found in the smartphone. With HDMI video output, Bluetooth 4.0, and mobile hotspot functionality up to five tethered devices, the Atrix HD is expected to be a hit with tech geeks.

Despite Samsung's latest Galaxy S3 hogging the limelight as of now, Motorola's upcoming device still stands a chance to compete with the South-Korean company's third generation smartphone. Amongst the features Galaxy S3 sports are an 8-megapixel rear-facing camera, a powerful Li-Ion 2100 mAh battery, LTE support for specific regions, and a massive 4.8-inch HD display that's backed by a 1.4 GHz quad-core processor. Taking into comparison these specifications, Motorola has scored well with its Atrix HD.

Moreover, the Motorola smartphone, which looks quite similar to Droid RAZR, is relatively thinner at 8.4mm compared to Galaxy S3's 8.6 mm thickness. Another noticeable change that one might find is that the Atrix HD offers light user interface modifications and also includes the Smart Actions application that's found in Droid RAZR.
