AMD Discontinues Driver Support for Ryzen Z1 CPUs
AMD has ended driver support for its Ryzen Z1 series of processors. The move may signal a transition in the company's product strategy for the handheld and embedded device markets. This decision serves as a reminder for embedded product designers of the importance of tracking silicon lifecycles and manufacturer support windows.
- The Ryzen Z1 and Z1 Extreme processors were officially launched in April 2023, making them roughly two and a half years old at the time support was reportedly discontinued. These "Zen 4" architecture-based chips were designed specifically for handheld PC gaming consoles. - Key devices impacted by this decision include popular handhelds like the Asus ROG Ally, Asus ROG Ally X, and the Lenovo Legion Go. Reports of the driver support cessation originated from a Lenovo Korea support forum, which stated there were no further driver update plans for the original Legion Go. - Owners of affected devices have noted the last stable driver update was released in August 2025, leaving them without optimizations for newer game releases. This lack of updates can result in poorer performance or compatibility issues with future software. - The process for updating drivers on these handhelds is complex, as AMD provides base drivers to Original Equipment Manufacturers (OEMs) like Asus and Lenovo. These OEMs must then test and validate the drivers for their specific hardware configurations, which feature a configurable TDP (cTDP) ranging from 9 to 30 watts. - While official confirmation from AMD has been lacking, the halt in updates for the Z1 series contrasts with the continued support for its successor, the Z2 Extreme. Lenovo has specifically warned users against trying to install drivers intended for newer models, like the Legion Go S, onto the original Legion Go due to incompatibility. - The Z1 Extreme is an 8-core, 16-thread processor built on a 4nm process, featuring integrated RDNA 3 graphics. It was first launched in partnership with Asus for the ROG Ally handheld console. - Competitors in the handheld space, such as those using Intel Meteor Lake chips like the MSI Claw, are continuing to receive regular driver updates, including support for new technologies like XeSS 3. - AMD's next generation of handheld processors includes the Ryzen Z2 series, which is based on the newer Zen 5 architecture and features RDNA 3.5-based integrated graphics.
