According to Tom's Hardware, AMD has begun adding GDDR7 memory support to its open-source Linux kernel driver, along with patches for new graphics IP blocks: IH 8.0 (interrupt handler) and NBIF 7.10 (bus interface). The changes follow earlier driver work for Display Core Next 6 and GFX 13.0.x, suggesting AMD is steadily upstreaming components of a future GPU architecture.
The source notes AMD has not identified the architecture, but the GDDR7 addition is the most explicit sign yet that standalone Radeon GPUs are in the works. Current RX 9000-series cards use RDNA 4 with GDDR6, so GDDR7 support implies a next-generation discrete GPU, likely tied to RDNA 5. Still, software enablement does not mean an imminent launch, and AMD has disclosed no official RDNA 5 details or schedule.
Tom's Hardware also recalls that AMD's next-gen lead architect, Laks Pappu, was previously described as building chiplet-based and monolithic graphics SoCs, though that profile disclosure was later removed. Based on typical 2.5–3.5 year GPU development cycles, RDNA 5 could already be in testing, but the article advises treating these developments cautiously. No other sources were provided, so there are no conflicting accounts to compare.
