If these leaked photos are real, the new MacBook Pro could have an upgraded NVIDIA GeForce GT 650M (Kepler) Graphics chip inside of it.

Apparently, photos of the logic board for the new 15-inch MacBook Pro have showed up in two posts from the Chinese forum WeiPhone.com, and according to the poster, he claims that the new 15-inch MacBook Pro has no change in appearance, and Apple will be offering three CPU options in the new 15-inch MacBook Pro: a 2.3GHz, 2.5GHz or 2.7GHz Ivy Bridge processor. And most importantly, Apple will use Nvidia’s GeForce GT 650M graphics card with 1GB GDDR5 graphics memory in the new 15-inch MacBook Pro.

Another poster analyzed the above photos and compared them with the logic board on MacBook Pro 15-inch (MC723LL/A). And he found out that both logic boards have similar shapes, and screw holes seem to line up. The position of the graphics chip on both logic boards is the same too.
