AMD has a lot riding on Ryzen. The company's CPUs and SoCs haven't been able to compete with the performance of Intel's mainstream desktop offerings in most workloads for some time, and competition with the blue team's high-end desktop and server chips has been further out of the question. To say that the red team has a lot riding on Ryzen would be something of an understatement. Anandtech reports that the description of a presentation that AMD will give at the Game Developer Conference gives away a launch date some time before the end of of the conference on March 3.
GDC is scheduled to begin on February 27 and end on March 3. Anandtech has a screen capture of the presentation description that reads, in part: "Join AMD Game Engineering team members for an introduction to the recently-launched AMD Ryzen CPU followed by advanced optimization topics." The page has since been altered to remove the phrase "recently launched." If Ryzen CPUs do in fact launch before March 3, the launch will have taken place well in advance of the end of AMD's first fiscal quarter at the end of March.
AMD fans and anyone looking to put together a machine for content creation has been looking forward to the new chip's launch ever since the company first put the new architecture on its roadmap back in mid-2015. AMD CEO Lisa Su has been promising a Q1 2017 launch for chips based on the Zen architecture since an announcement in the shadow of the Intel Developer Forum in San Francisco in August.
