LG Optimus 2X vs Motorola Atrix 4G: Dual-Core Performance Battle

We’ve been giving you a lot of stories about the Motorola Atrix 4G Android smartphone recently, which has now been released on AT&T. This dual-core Tegra 2 processor handset, with 4-inch display, 1024MB of RAM and 5-megapixel camera, has impressed a lot of people, including us. Now we are wondering how it performs up against other dual-core Android phones such as the LG Optimus 2X and also some single-core processor handsets.

Among our most recent articles on the Atrix 4G were a teardown look inside the handset, a ponder about whether it could be the best Android on AT&T, release and price details and a comparison against the Samsung Galaxy S2. The LG Optimus 2X has also had a lot of press and we included it in our pick of the best LG smartphones, and looked at a rather mixed review. There’s been a lot of fuss made about the new dual-core processor phones but how do they compare performance-wise?

This is where an article by Taylor Wimberly over on Android and Me comes in as they tested a range of 6 phones to see how they rack up against each other. The test lineup consisted of the two dual-core Tegra 2 phones available to them, the Atrix 4G and the Optimus 2X and also four single-core processor phones, the Nexus S, T-Mobile G2, Nexus One and Motorola Droid. Tests performed were Neocore, Nenamark1, Smartbench 2011 (Productivity and Games), and others and you can see the full results for each test with graphs over at the Android and Me link above.

In the Neocore test the LG Optimus 2X easily led with 77.2 fps while the Atrix 4G was down in fourth position. However the article points out that because the Atrix 4G has a higher resolution it has to work harder. The Nenamark1 tests again showed the LG Optimus 2X on top with the Nexus 2 coming second beating the Atrix 4G which in third. As far as the Smartbench 2011 tests are concerned the Productivity test showed the Atrix 4G as the leader but only just pipping the Optimus 2X. Both dual-core phones significantly beat all the single-core processor handsets at around three times the productivity performance. For the Games test the Optimus 2X just took the top spot from the Atrix 4G.

There are many more tests included but the conclusion is that the benchmark tests showed significant speed improvements for the dual-core phones over the single-core phones, as you may have expected but that overall although the Optimus 2X often topped the lists, the Atrix 4G wasn’t always as high up as we may have anticipated. If you want to find out more about the Atrix 4G head to the Motorola product pages for it here.
