Recent media analysis suggests that AMD’s next-generation UDNA architecture will bring significant performance gains to Radeon GPUs, as well as the PlayStation 6 and next-gen Xbox consoles. This new unified architecture will replace the existing RDNA and CDNA architectures, integrating consumer and data center GPU designs. It aims to optimize rasterization, ray tracing, and AI performance, offering a more efficient graphics experience for gamers and tech enthusiasts.
Core Optimizations and Rasterization Performance #
The core of the UDNA architecture lies in its optimization of compute units. Compared to the RDNA 4 architecture released earlier this year, UDNA boasts approximately a 20% improvement in rasterization performance per compute unit. For example, while the Radeon RX 9070 XT only features 64 RDNA 4 compute units (fewer than RDNA 3’s 96), its rasterization performance is already close to that of the previous generation’s flagship. The UDNA architecture will further increase the number of compute units. UDNA’s compute units enhance instruction throughput and frequency by improving VRAM management and dynamic register allocation, allowing GPU Boost frequencies to approach 3GHz, thus achieving higher efficiency in traditional rendering tasks.
Significant Ray Tracing Advancements #
Ray tracing performance is another major highlight of the UDNA architecture. Compared to RDNA 4, UDNA’s ray tracing performance sees an impressive 100% improvement, thanks to the redesigned third-generation ray tracing accelerators. The new accelerators utilize “directional bounding box” technology to optimize Bounding Volume Hierarchy (BVH) data structures, reducing VRAM usage and improving ray traversal efficiency. Additionally, a new second intersection engine doubles the speed of Ray/Box and Ray/Triangle processing, while a dedicated ray transformation engine further enhances low-level BVH traversal performance. These improvements will significantly boost lighting, shadow, and reflection effects in ray-traced games, providing players with a more realistic visual experience.
Enhanced AI Performance and FSR 4 Redstone #
The boost in AI performance is equally remarkable. The UDNA architecture is equipped with second-generation AI accelerators that support FP8 and INT4 data formats, include new math pipelines, and optimize structured sparsity. This results in an 8x increase in AI computing performance compared to RDNA 4. This not only provides powerful support for neural network inference but also enhances the capabilities of AMD FidelityFX Super Resolution (FSR) sharpening technology. FSR 4 Redstone is AMD’s latest super-resolution technology, integrating neural network caching and machine learning-accelerated ray tracing and frame generation. By predicting indirect light reflection positions, neural network caching reduces the need for full path tracing, thereby improving performance and lowering power consumption. FSR 4 Redstone now supports over 65 games and is expected to expand to 75 by year-end, significantly boosting frame rates and image quality in 4K gaming.
Impact on Next-Gen Consoles #
The UDNA architecture will also be applied to next-generation game consoles. Both the PlayStation 6 and the next-gen Xbox will adopt the unified UDNA GPU architecture, paired with Zen 4 or Zen 5 CPUs. Unlike the PS5 Pro’s hybrid RDNA 3/4 architecture, the UDNA architecture will not rely on deep customization from Sony or Microsoft, with performance gains almost entirely attributed to AMD’s core technology. However, the UDNA SoC does not integrate 3D cache, which might surprise some players. Nevertheless, the unified architectural design will reduce development complexity, providing game developers with a more consistent optimization platform.
Display and Media Capabilities #
In terms of display and media processing, the UDNA architecture supports the AMD Radiance Display Engine, compatible with DisplayPort 2.1a and HDMI 2.1b. This enables ultra-high resolutions and refresh rates up to 8K 144Hz, along with 12-bit HDR and REC2020 color gamut, ensuring excellent color accuracy. The enhanced media engine supports AV1, HEVC, and H.264 codecs, offering professional-grade recording and streaming experiences. Combined with AMD FreeSync technology, UDNA can deliver tear-free and stutter-free gaming on over 4,000 compatible monitors.
Strategic Shift and Market Outlook #
The introduction of the UDNA architecture marks a significant shift in AMD’s GPU strategy. By unifying RDNA and CDNA, AMD is poised to challenge Nvidia’s CUDA ecosystem, aiming to attract more developers and expand market share. UDNA is not only targeting the gaming market but will also support AI and high-performance computing tasks. It is expected to enter mass production in Q2 2026, coinciding with the launch of the Radeon RX 9000 series graphics cards. Furthermore, UDNA will utilize TSMC’s N3E manufacturing process, further enhancing power efficiency and performance.
The release of the UDNA architecture comes at a crucial time as the gaming industry transitions towards ray tracing and AI-driven rendering technologies. Through FSR 4 Redstone and enhanced AI accelerators, AMD provides powerful support for super-resolution and frame generation, ensuring smooth frame rates even in high-load 4K ray-traced scenarios. Compared to Nvidia’s DLSS, FSR 4 has significantly narrowed the gap in image quality, particularly excelling in detail clarity and distant object rendering. For example, in 4K tests of Call of Duty: Black Ops 6, FSR 4 demonstrated excellent edge sharpening and shadow details.
The unified design of the UDNA architecture not only brings performance improvements to players but also lays the foundation for AMD’s long-term development. By integrating consumer and enterprise GPU architectures, AMD will more efficiently allocate R&D resources, accelerating technological iteration. UDNA is expected to boost AMD’s competitiveness in the mainstream gaming market and high-performance computing fields, injecting new vitality into the next generation of Radeon graphics cards and game consoles.
