The chip included in the benchmarked machine is a Core i7-4950HQ running at 2.4 GHz and offering Intel's new high-end Iris Pro 5200 integrated graphics. Intel's promotional materials for Iris previously showed graphics performance gains of 2-2.5x for this i7-4950Q with Iris 5200 compared to the i7-3840QM with HD Graphics 4000 found in the current stock high-end Retina MacBook Pro.
Apple typically includes a dedicated graphics chip with their 15-inch MacBook Pro; however, the site speculates that perhaps Apple will only use integrated graphics for some models to improve battery life even further. Currently the 15-inch MacBook Pro offers up to 7 hours of battery life.
