Intel’s line of Ultrabooks now have a little bit of competition in the war to take back some of the ultraportable laptop market share from Apple’s Macbook Air.

Earlier this week Hewlett Packard announced the Sleekbook, which is everything an Ultrabook is save for the inclusion of a Trinity APU from AMD instead of an Intel chip. As the inclusion of the Trinity APU allows for some cost savings, HP’s ENVY Sleekbooks come in at a lower pricepoint than their Ultrabook peers: $600 and $700 for the 15.6-inch and 14-inch models, respectively.

HP says these models will get between 8 to 9 hours of battery life, which is on par or slightly above current Ultrabook offerings.

According to published stats, these ENVY Sleekbooks are approximately the same dimensions as an average Ultrabook: both the 15.6 and 14-inch models are 19.8mm thick; the 15.6-inch model weighs 1.81 kg while the 14-inch comes in at 1.7kg.

Both models will have a screen resolution of 1366×768, and an HD webcam. The Sleekbooks will also include two USB 3.0 ports, HDMI, and a gigabit Ethernet port.

HP says the Envy 4 will be available with the option of just a 500GB hard disk or a 32GB mSATA cache drive and 500GB hard disk. The Envy 6 will offer a 120GB SSD and the option of a hard disk starting at 320GB.

It will be interesting to see how HP’s Trinity powered Sleekbooks compare to their Intel powered Ultrabook peers in benchmarking and sales.
