History

Historical Context

In July 2006 AMD announced a $5.4 billion all-stock purchase of Canadian graphics firm ATI Technologies, completing the deal on October 25 2006. The acquisition gave AMD in-house GPU design, enabling the later Fusion APUs that let it compete directly with Intel’s CPUs and Nvidia’s GPUs. This move built on AMD’s earlier strategy of buying complementary assets, such as the 2009 spin-off of its fabs into GlobalFoundries.
