AMD just dropped a one-line patch in its open-source Linux AMDGPU driver that adds "GDDR7" to the VRAM name lookup table, the first explicit signal the company is prepping next-gen Radeon silicon for the faster memory standard Nvidia already shipped in its RTX 50 series. Current RDNA 4 cards stick with GDDR6, so this tiny code tweak—spotted by Phoronix and covered across PC Gamer, Tom's Hardware, and VideoCardz—lines up with every other hint pointing at RDNA 5 (GFX 13 / DCN 6 work) ditching the old stuff for higher bandwidth.

The same patch batch also enables IH 8.0 interrupt handling and NBIF 7.10 bus interface blocks, continuing the slow, deliberate Linux enablement cycle AMD runs years ahead of launch. Leakers and board partners keep saying the first real RDNA 5 card, reportedly a mid-range "AT2" die, is the only one with any shot at a 2027 release while the rest of the stack slides into 2028 amid the ongoing memory crunch that favors AI silicon over gaming SKUs.

Nvidia moved to GDDR7 across most of its 50-series desktop cards at launch; AMD skipping it entirely on RDNA 4 now looks like deliberate positioning, and this driver change confirms they're not staying behind forever. Whether the memory shortage actually lets any of these cards hit shelves on time is the real bracket to watch.
