Recent updates from AMD's ROCm (Radeon Open Compute Platform) have provided new details about the RDNA 4 GPU architecture, confirming the upcoming release of two GPU models: Navi 44 and Navi 48. This information, seen in the ROCm's GitHub repository, confirms AMD's product plans for its next generation of GPUs, which will follow the RDNA 3 architecture used in the Radeon RX 7000 series graphics cards. The RDNA 4 GPU architecture represents AMD's ongoing development in graphic processing technology. In a shift from previous naming conventions where smaller numerical identifiers indicated larger models, the RDNA 4 architecture reverses this trend. Under this new convention, Navi 48 is anticipated to be a higher-end model compared to Navi 44, which suggests potential product names such as Radeon RX 8800 for the Navi 48 and Radeon RX 8600 for the Navi 44.

Despite advancements in architecture, AMD will continue to use GDDR6 memory in the RDNA 4 GPUs instead of transitioning to GDDR7, opting to maintain a balance between cost and performance enhancements. This decision aligns with the industry's gradual memory technology adoption rates and reflects a strategic choice to maximize compatibility and appeal within the existing market conditions.

The expected release timeframe for the Radeon RX 8000 series, which will house the RDNA 4 architecture, is not slated for 2024. Indications point towards a launch in the first quarter of 2025, aligning with AMD's typical product release cycle and giving ample time for further development and market preparation.
