According to a leak from the Chiphell forum, AMD's next-generation graphics architecture, UDNA, is set to power its Radeon gaming GPUs and potentially the upcoming Sony PlayStation 6 (PS6). Mass production is reportedly planned for Q2 2026.
UDNA: A Unified Architecture
UDNA aims to unify AMD's CDNA (Instinct) and RDNA (Radeon) architectures. This marks a departure from AMD's current dual-architecture approach, streamlining development and potentially improving performance and efficiency.
Radeon RX 9000 Series and PS6
The leak suggests that the Radeon RX 9000 series will utilize the UDNA architecture. While the naming isn't confirmed, AMD typically rebrands its gaming GPUs with new architecture launches. Importantly, the PS6 is also rumored to feature UDNA, potentially leveraging the same compute capabilities as the next-gen Radeon cards.
The leaker also states that the UDNA architecture will share a similar ALU design to the older GCN architecture, indicating a fresh approach rather than an iterative update.
Other Key Points from the Leak:
- The current "CDNA-Next" Instinct MI400 series will also transition to the UDNA branding.
- RDNA 4 will be the final generation using that naming convention.
- AMD is developing an AI-enhanced FSR solution, similar to NVIDIA's DLSS.
- The PS6 CPU architecture (Zen 4 or Zen 5) is currently unconfirmed. AMD hardware is also expected to power the next-gen Sony handheld.
- Microsoft is reportedly considering either Qualcomm or AMD for its upcoming handheld console.
Impact and Future Outlook
With RDNA 4 targeting the mainstream market, it will be interesting to see if the first-generation UDNA architecture will allow AMD to reclaim a stronger presence in the high-end enthusiast market dominated by NVIDIA. The integration of UDNA into the PS6 further underscores its importance in AMD's future.
