Acer on Thursday announced the Iconia Tab A510 tablet with Android 4.0, joining the growing market of device makers releasing quad-core tablets.

The tablet has a 10.1-inch screen, and the device is designed for video and mobile gaming, Acer said in a statement. Acer until now has offered only dual-core tablets, and the latest tablet is the first with a quad-core processor.

The Iconia Tab A510 is available for pre-sale for $449.99 in the U.S. and Canada. Acer's competitors that have already announced or are shipping quad-core Android tablets includes Asus, Lenovo and others.

Acer estimates the A510 tablet can provide 12 hours of video playback time. The Asus Eee Pad Transformer quad-core tablet in the past received positive reviews partly for long battery life.

The A510 tablet has a screen that displays images at a 1280-by-800 pixel resolution, which is comparable to screens on other Android tablets. However, the A510 screen pales in comparison to the 2048-by-1536 resolution display of Apple's new iPad, which started shipping last week. The A510 can display 720p images, Acer said, while Apple's iPad can display full 1080p high-definition images because of the high-resolution screen.
