The previously built-in Nvidia Geforce 320M was definitely more powerful.

To sum things up, buying the new MacBook Pro 13 means better CPU performance at the expense of graphics rendering power. This translates to a decrease in performance of 13 – 46% depending on the benchmark at hand. The difference becomes still more pronounced in the 3D Mark '06 Benchmark, where the new on-board GPU is behind at a mere 2550 points, compared to the 4707 points of the GeForce at a resolution of 1280x800 pixels. The Intel HD Graphics 3000 in the new MBP 13 isn't quite up to muster, working at a slower 10.94 Bps. The Nvidia GeForce 320M from last year's MBP 13 managed 12.61 Bps in the Cinebench R11.5 OpenGL test. The level of graphics card performance isn't quite as exciting. In the Apple Store, its priced starting at 1150 Euro, but other retailers are offering it starting at under 1100 Euro. The basic configuration of the MBP 13 reviewed here is equipped with an Intel Core i5-2415 CPU, Intel HD Graphics 3000, 4 GB RAM, 320 GB hard drive and the brand new Thunderbolt port. Now, Apple has finally made the leap to a new set of processors, since on the one hand the Intel HD Graphics 3000 comes much closer to satisfying Apple's high standards and-on the other hand-it would truly be astounding if Apple still stayed with an older generation of processors. Choosing to replace the graphics card instead, Apple chose to house the Nvidia GeForce 320M in the MBP 13 in mid 2010 rather than switching to Core i5 processors (since the included Intel HD on-board graphics card didn't jive with Apple's preferences)-our review of that model was aptly tagged graphics update. Apple fans have anxiously been awaiting the current revision of the small MacBook Pro, having to make due with the antiquated Core 2 Duo series processors until now.
