According to the statement from AMD's Computing and Graphics SVP, Jack Huynh, the initial production units that were shipped to channel partners do not meet full quality expectations. AMD is now working to replace the initial production units, which will result in a short delay in retail availability.

The Ryzen 7 9700X and Ryzen 5 9600X processors will be available on August 8th, while the flagship Ryzen 9 9950X and Ryzen 9 9900X processors will go on sale on August 15th.

We appreciate the excitement around Ryzen 9000 series processors. During final checks, we found the initial production units that were shipped to our channel partners did not meet our full quality expectations. Out of an abundance of caution and to maintain the highest quality experiences for every Ryzen user, we are working with our channel partners to replace the initial production units with fresh units. As a result, there will be a short delay in retail availability. The Ryzen 7 9700X and Ryzen 5 9600X processors will now go on sale on August 8th and the Ryzen 9 9950X and Ryzen 9 9900X processors will go on-sale on August 15th. We pride ourselves in providing a high-quality experience for every Ryzen user, and we look forward to our fans having a great experience with the new Ryzen 9000 series.
