Nvidia had been touted as Apple's new mistress after they were seen holding hands and the Nvidia GeForce GT 650M graphics card was mentioned in OS X beta code.
But AMD has has been the mother of many of Apple's children. The MacBook Pros currently use AMD's Radeon HD 6770M and Radeon HD 6750M for graphics processing. AMD has been loyal despite rumours of Jobs' Mob's roving eye.
It turns out that 9to5Mac found Nvidia crying in the loos after Apple returned to AMD, after it had some plastic surgery and was sporting some nice new bouncy Trinty chips.
Nvidia should have seen the writing on the wall. The MacBook Pro is due in June and there is no way that Nvidia could be its parent.
It seems that the GeForce GT 650M with its offers of better performance for gaming was not enough to woo Apple back.
