LG Optimus 2X vs. Motorola Atrix 4G – Review

by Jerry D on February 21, 2011

It’s a battle of the dual-core phones… The LG Optimus 2x just hustled out the Motorola Atrix to grab the title of ‘world’s first dual-core phone’. But is first necessarily best? Let’s get this big phone fight on…

XXXX versus graphic LG Optimus 2X vs. Motorola Atrix 4G – Review XXXX


The Optimus 2X is equipped with a 3G/HSDPA (10.2Mbps) chipset, along with 802.11b/g/n Wi-Fi and Bluetooth 2.1 with A2DP. The Atrix, meanwhile, boasts 3G/HSDPA/HSPA+ (14.4Mbps), 802.11b/g/n Wi-Fi and Bluetooth 2.1 with A2DP and EDR. (0-1)

Size & Weight:

Contrast the two phones and the Optimus 2X is ever-so-slightly fatter than the Atrix with dimensions of 10.9mm versus 10.1mm. The Atrix, however, is broader, measuring 63.5mm to the Optimus 2X’s 63.2mm. But you won’t even notice. Measure the weight of the duo and the Optimus 2X weighs 139g, while the Motorola Atrix is 136g. There’s practically nothing between them. (0-1)



The Optimus 2X rocks an 8.0 Megapixel camera (3264 x 2448 pixels) with autofocus, an LED flash, geo-tagging and top-of-the-line Full HD (1080p) video recording. For video calls, there’s also a front-facing camera.

The Atrix, in comparison, boasts a decent 5.0 Megapixel camera with autofocus, an LED flash, image stabilization, geo-tagging and 720p video capture. But it’s no match for the Optimus 2X. That said, the Atrix does also include a second camera on the front, which can be used for video calling. (1-1)


The Optimus 2X features a 4.0-inch touch-sensitive LCD display with a resolution of 480 x 800 pixels. The screen has 384000 pixels in total, giving it a rating of 233.25 pixels per inch.

The Atrix’s touch-sensitive LCD display is the same size. But with a higher resolution display (540 x 960 pixels) and with 518400 pixels onscreen, the pixel density is 275.25 pixels per inch. (1-2)


How speedy are the two combatants? The Atrix uses a Dual-core NVIDIA Tegra 2 processor, rated at 1GHz. The Optimus 2X’s core is also a 1GHz NVIDIA Tegra 2, which incorporates a dual-core ARM Cortex A9 chip and ULP GeForce graphics GPU. (1-2)


As for the operating systems, the Optimus 2X runs Android 2.2 (Froyo), which LG promises will be upgradeable to 2.3 (Gingerbread) in time. The Atrix uses the same Android build, enhanced with Motorola’s MotoBlur. Like the 2X, an update to Android 2.3 is planned for later in the year. (1-2)


The 16GB in the Atrix trumps the 8GB capacity of the Optimus 2X. The Optimus 2X also has a microSD interface, which can extend the overall capacity to 40GB. The inclusion of a microSD expansion slot on the Atrix bumps up the capacity to 48GB. (1-3)

Battery life:

So how much battery life do you get? The Optimus 2X boasts 8.0 hours of talktime according to LG, while the Atrix is rated at 9.0 hours. Standby time is rated at 400 hours and 250 hours respectively. So the Optimus 2X loses this one. (1-4)


Note: The Standby time specification is an industry standard that is only intended to allow comparison of different mobile phones under the same circumstances. Power consumption in a standby state is strongly dependent on factors including: network, settings, location, movement, signal strength and cell traffic.


The Optimus 2X also includes GPS/A-GPS, DLNA content sharing, HD (720p) TV-out via HDMI, a digital compass and a gyro-sensor.

In comparison, the Atrix features GPS/A-GPS, Gorilla Glass, an HDMI out, 1080p capable video playback (via post-launch software update), an eCompass, stereo FM radio with RDS and a very clever laptop docking capability. (1-5)

The Motorola Atrix 4G wins!

The LG Optimus 2X might have been the first dual-core phone, but it’s been eclipsed by the Motorola Atrix 4G. Where? The Atrix has support for HSPA+, more memory and a far superior screen, which comes closest to matching the resolution of the iPhone 4.
