AMD's next-generation gaming graphics cards featuring the RDNA 5 GPU architecture are unlikely to debut before the second half of 2027, according to well-known hardware leaker Kepler_L2. The leaker suggests that AMD is unlikely to release any RDNA 5 desktop graphics cards before Computex 2027, indicating that these GPUs will probably arrive in the latter half of that year. AMD is expected to lead with the silicon codenamed "AT2," which is part of a family of discrete RDNA 5 GPUs. This will be followed by "AT0," "AT3," and "AT4," which are expected to launch a few quarters later in 2028.
Since "AT2" likely refers to a mid-range design, AMD might begin its rollout with a mid-range GPU first, followed by flagship and lower-end models in 2028. Previously, it was learned that AMD's RDNA 5 GPUs will incorporate GDDR7 memory with unknown capacities, as GDDR7 is now listed among the supported VRAM types in the AMDGPU driver. Currently, AMD's graphics cards use GDDR6 for the consumer RDNA 4-based Radeon RX 9000 series, while Instinct MI data center and workstation GPUs use HBM3E and HBM4 memory. Since AMD is developing data center GPUs with HBM and consumer cards are the only models using GDDR, the GDDR7 placeholder suggests future support for RDNA 5.
Additional details reveal that the Display Core Next (DCN) 6 display engine, responsible for display output, image scaling, monitor ratio output, and pixel manipulation, will debut in version 6 for RDNA 5. With DCN 6, AMD has introduced new scaling integrity and cost surfaces, a UPSP pre-scaler to sample 4:2:0 and 4:2:2 content before scaling, and new pixel formats within the display logic. This means the final GPU will support modern high-refresh and high-resolution gaming across various aspect ratios and configurations, ensuring smooth content delivery.
