AMD Linux Driver Gains GDDR7 Support for Future GPUs
A new patch adds GDDR7 recognition to the AMDGPU driver, signaling preparation for next-generation Radeon hardware.
Key points
- AMD's Linux driver now recognizes GDDR7 memory, indicating support for future Radeon GPUs.
- The update includes new hardware blocks like IH 8.0 and NBIF 7.10 alongside the memory change.
- Current RX 9000 cards use GDDR6, but the driver shift suggests next-gen models will use GDDR7.
AMD has quietly updated its open-source Linux graphics driver to recognize GDDR7 memory. This change marks the first direct reference to the next-generation video RAM standard within the company's software stack, suggesting that upcoming Radeon GPUs will move away from the current GDDR6 standard.
The update is a small but significant code addition that lists GDDR7 alongside existing memory types like GDDR6 and HBM. While the patch does not name a specific product, it aligns with industry expectations that AMD's next architecture will adopt faster memory to compete with recent NVIDIA releases that already use GDDR7.
Driver patch adds new memory type
According to reports from videocardz.com, the change was implemented by AMD engineer Frank Min. The patch adds a specific identifier for GDDR7 to the list of memory types recognized by the amdgpu driver. This allows the operating system to correctly identify and manage the new memory chips once they appear in consumer hardware.
The modification was reviewed by senior AMD staff and submitted by Alex Deucher, a key maintainer of the AMDGPU driver. By adding this support now, AMD ensures that its software foundation is ready before the hardware ships, preventing potential compatibility issues for early adopters of the next generation of graphics cards.
Support includes new hardware blocks
The GDDR7 support is part of a broader set of updates aimed at enabling future AMD hardware. The same wave of patches includes support for IH 8.0, a new revision of the interrupt handler, and NBIF 7.10, an updated bus interface. These components work together to manage data flow and system communication within the GPU.
Additionally, recent driver work has included changes for Display Core Next 6, or DCN 6. These updates are already present in the Linux 7.3 kernel and are expected in version 7.4. This indicates that AMD is preparing its software ecosystem for a full refresh of its internal graphics and display architecture, not just a memory upgrade.
Next-gen Radeon cards likely to use it
Current Radeon RX 9000 series cards, based on the RDNA 4 architecture, still use GDDR6 memory. However, competitors have already shifted to GDDR7 in their latest desktop products. The addition of GDDR7 support in the Linux driver strongly implies that AMD's next generation, widely rumored to be RDNA 5, will adopt this faster memory technology.
AMD has not officially announced memory specifications for its next graphics cards, but the driver changes provide a clear technical signal. This move positions AMD to offer higher bandwidth and potentially better performance in future high-end GPUs, addressing a key area of competition in the desktop graphics market.
