At Apple’s latest product event, the Cupertino-based company announced two new additions to the MacBook Pro lineup — along with the previously-announced Mac Pro. As previously speculated, both the 13-inch and 15-inch models sport Intel Haswell processors found in the new Macbook Air, while touting the same Retina displays adorning the 2012 MacBook Pro. Both the 13-inch and 15-inch MacBook Pros feature the newly-launched Mavericks OS, in addition to 802.11ac Wi-Fi and Thunderbolt 2.0, and integrated graphics courtesy of Intel Iris and Iris Pro.

Cosmetically, the new models aren’t vastly different. The 13-inch model 15-inch models are slightly thinner and lighter than their predecessors, measuring 0.71 inches thick and weighing in at 3.46 and 4.46 pounds, respectively. Apple claims that battery life has gotten a significant boost thanks to updated specs and software optimization courtesy of Mavericks. This could extend battery life an additional two hours beyond the previous models, offering a total of up to nine hours of usage and 30 hours of standby time. Although the $1,999 15-inch model ships with Intel’s Iris Pro integrated graphics, users can always opt the $2,599 model, which includes a Nvidia GeForce GT 750M GPU which should provide you with more graphics processing power over Iris Pro.

The 13-inch MacBook Pro starts at $1,299, while the 15-inch MacBook comes in at $1,999. Both are on sale now. Check out our comprehensive spec comparison for a closer look at how the 2013 MacBook Pro stacks up against last year’s Retina Macbook Pro.
