Rumors started over the past weekend about Apple's plans suggest that it will not embrace Intel's āArrandaleā line of chips, at least for now. The standard format of the models that will be present in it brings an integrated graphic chipset, a component already considered as the main reason for the rejection of its use in MacBooks.

Along with this line (which initially offers three models of processors), Apple would also have rejected the āCalpellaā platform (suggested for Mac mini), due to the same reason. While the graphics power that exists in Intel's new integrated GPUs has grown significantly, it appears that future updates to the Mac line will not stop using NVIDIA graphics solutions.
The source of the speculation suggests that Intel would have to provide a special version of the āArrandaleā chips to Apple (without integrated graphics), but although the two companies have shown signs of mutual collaboration in the past, the technical implications for this would not be very favorable for those who produce processors. In addition, it will still be possible to include a dedicated GPU in the architecture of future MacBooks Pro, even based on processors with integrated graphics already included.
All this concern about the future of Apple laptops is greatly affected by the legal fight between Intel and NVIDIA, in which the current supplier of GPUs for Macs was prevented from producing new chipsets for them, in order to work with the Core i5, i7 and later. Since then, some Ma products have been produced in formats that avoid using these components, including the Mac Pro and models quad-core of the new 27-inch iMac.
