On Tuesday, Nvidia announced a "GeForce Special Event" on Sept.

1, during which CEO Jensen Huang will speak about the chipmaker's "latest innovations in gaming and graphics." Meanwhile, the website for the event promises to unveil "the biggest breakthroughs in PC gaming since 1999." .

1999 was the year Nvidia introduced its first GeForce graphics processing unit for the gaming market.

Analysts say the debut of next-generation graphics chips could spark a major upgrade cycle, which should fuel growth for Nvidia and fellow chipmaker Advanced Micro Devices. .
