According to an investigation, Apple’s latest-generation MacBook Pro systems may face the same material defect in their dedicated graphics hardware as encountered by earlier models. The integrated GeForce 9400M chipset, which is used across all of Apple’s new MacBooks as well as a handful of newer Windows systems, is shown to use proper eutectic (low melting point) bumps and so shouldn’t be prone to the same issues. The related 9300M and the low-end 6400 lineup should also be reliable.
It’s unclear whether the issue affects all MacBook Pros, though the sample used to reach the findings was a retail example from just after the official launch in mid-October. Numerous reports have surfaced in Apple’s support forums of screens going black in graphics-intensive games and of excessive heat in other conditions, though NVIDIA is already understood to be transitioning over to the true eutectic bumps for all its video hardware.
