While Apple's MacBook Air got its direly needed hardware upgrade this June, it left its MacBook Pro lineup untouched. The company plans to hold a press event in September, when it plans to unveil its next MacBook Pro lineup. These could include MacBook Pro driven by Core "Haswell" GT3e processors, which feature large integrated graphics cores, featuring 40 execution units, allowing it to do away with discrete GPUs, and improve battery life. A new rumor doing rounds in the tech circles states that Apple could make Intel build-to-order a new class of Haswell GT3e processors with even faster graphics cores than Iris 5200, the graphics core inside today's Core i7-4950HQ.
