Lenovo is offering two levels of their new Ultrabook series, the U410 with a Core i7-3517U, 8 GB DDR3-1333 RAM and a 1GB GeForce 610 while the U310 sports a Core i5 3317U, 4GB DDR3-1600 and relies on the built in HD4000.  There is another major difference as well, the U310 may be less powerful but its chassis is more attractive and comes in a variety of colours, making it perfect for those who need a bit of mobile power but not something focused on performance.  The lack of a discrete GPU also lowers the price and makes it more affordable for students.  Hardware.Info reviewed both of them separately, the U310 here and the more impressive U410 here.

"For the price you get a pretty powerful and well-equipped Ultrabook. Most brands offer a Core i5 at this level, but Lenovo includes an energy-efficient Core i7 and 8 GB memory. And instead of the typical 500 GB hard drive you get a 1 TB version and even a dedicated graphics card by Nvidia. While it's just the GeForce 610, it's still a nice addition."
