AMD is announcing the Ryzen 5 5600X3D -- except the launch is being handled entirely by Microcenter, including distribution of news, press releases, review samples, and handling of the product. The R5 5600X3D is a peculiar launch: It will be exclusive to Microcenter and, from what the retailer told us, it will be in-store only. Supply is expected to last maximally 3-6 months. The 5600X3D is likely the final AM4 chip that will ever launch, technically extending the platform's life into 2023.
