alt Hacker NewsApple used nVidia GPUs in most of its computers. Around 2008-2009, nVidia produced a line of faulty GPUs that were used in the Macbook Pro. This led to widespread hardware failures, and was known as "Bumpgate" because the problem was caused by faulty solder bumps inside the GPU chip. nVidia refused to fully reimburse Apple for repairs because it wasn't contractually obligated to do so. In response, Apple switched away entirely from nVidia GPUs.
I think it was well into 2013 because both the 2011 and 2013 MBPs I had suffered from it. but I thought that was an apple issue (ie not soldering the dicrete gpu well enough to save money on it)
after the 2 faulty products in a row, I haven't bought an apple product since.
