AMD is one of the world’s biggest computer chip companies, best known for its fierce competition with Intel. It’s a rivalry that really kicked off in the early 2000s when AMD’s Athlon and Opteron processors saw great success. While AMD has often struggled to keep up with Intel, its latest Ryzen Zen 3 and Zen 4 CPUs are some of the most competitive chips it has produced in years. AMD also acquired ATI in 2006, a 3D graphics card company. It now produces a variety of Radeon GPUs that compete with Nvidia’s GeForce line of graphics cards. AMD also produces the chips found in the latest PS5 and Xbox Series X / S consoles and re-entered the server market with its Epyc brand in 2017.
