AMD is expanding its RDNA1-based Cyan Skillfish APUs with five new PCI device IDs. Discover why AMD still supports Navi 1x graphics in 2024, how it compares to RDNA 3.5 & 4.5, and what this means for Linux developers & budget devices.
AMD’s Surprising Move with Older RDNA1 Architecture
While the tech world eagerly awaits next-gen RDNA 4.5 and Strix Halo APUs, AMD is quietly expanding its RDNA1-based "Cyan Skillfish" APU lineup.
Recent open-source Linux driver patches reveal five new PCI device IDs, signaling that AMD isn’t done with its older Navi 1x graphics architecture.
Why would AMD invest in aging RDNA1-based APUs when RDNA 3.5 and RDNA 4.5 are on the horizon? The answer likely lies in cost-sensitive markets, embedded systems, and budget-friendly devices where cutting-edge performance isn’t a priority.
Breaking Down the New Cyan Skillfish Patches
1. New PCI Device IDs Added to AMDGPU Linux Driver
AMD’s latest patch series introduces five new PCI device IDs for Cyan Skillfish APUs:
0x13DB
0x13F9
0x13FA
0x13FB
0x13FC
These additions confirm that new APUs with RDNA1 graphics are in development, despite the architecture being four years old.
2. Cyan Skillfish: A Brief History
Originally introduced in 2021, Cyan Skillfish APUs were designed for Linux-based systems with Navi 1x (RDNA1) graphics.
While outdated compared to RDNA 3.5 (GFX1151) and upcoming RDNA 4.5 (GFX1250), these chips still serve niche markets requiring stable, open-source driver support.
3. Why RDNA1 in 2024? Market Strategy Explained
Cost Efficiency: RDNA1 is mature, reducing production costs.
Embedded & Industrial Use: Reliable for IoT, kiosks, and low-power systems.
Linux Compatibility: Strong open-source driver support benefits developers.
