Who knows what would’ve happened
Recently, Forbes magazine got an ex-AMD employee to open up about the company. It turns out back in 2006, before AMD acquired ATI in order to get into the GPU business, it almost went ahead and acquired NVIDIA. According to the ex-AMD employee, AMD actually had NVIDIA as first pick ahead of ATI but the deal went under because NVIDIA CEO Huang, insisted on being chief executive of the resulting combined company.
So instead, AMD went ahead with the acquisition of ATI for its fledgling graphics division. And the rest as they say, is history.
NVIDIA has since developed massively on a number of fronts. It has dominated the graphics processor industry, introduced new technologies like PhysX and stereoscopic 3D vision, and then made a splash in the mobile industry with its Tegra graphics chips and it is still going strong. But then again, who can say that NVIDIA under AMD would have been such a success?
