Wow, people are desperately grasping at straws for a tiny glimmer of hope that there will be a discrete GPU.
Guess what. Not gonna happen, with all those batteries, and soldered RAM, simply no room.
.
I can agree with you until I see two Thunderbolt ports and an HDMI port. How does an Intel HD4000 drive the native Retina and three external displays? It will take a 650M to drive them, will it not?
I was convinced Apple would only include the Intel HD4000 until I saw that port configuration. I don't get what else it could mean? Apple only allows one TB port to work for display? Or either a TB or HDMI port can work, but not both simultaneously with displays connected?
I just don't see the same concept of two 27" ACDs, a Retina native display, and a 1080P HDMI display all driven by an Intel HD4000.
Please explain what the port configuration means. I completely agree that there isn't much room for a dGPU, but I am not an computer science engineer. Less the optical drive, and the same thickness as the 15" rMBP, and there is no way for a dGPU?
Thanks in advance for your reply.
