AMD will be utilizing "slow" 18Gbps GDDR6 memory modules with its next generation "RX 8000-series" RDNA 4 GPU lineup, according to a post from prolific leaker Kepler on X (Twitter). If true, this will be the fourth RDNA architecture in a row to utilize GDDR6 memory.
The first RDNA chips from the RX 5000-series used GDDR6 clocked at 12–14 Gbps. RDNA 2 and RX 6000-series GPUs bumped that to 14–18 Gbps (note that only the RX 6600 uses 14Gbps memory, while the others are all 16–18 Gbps). Most recently, RDNA 3 and the RX 7000-series GPUs have used 18–20 Gbps GDDR6 memory. So if RDNA 4 only uses 18Gbps chips, that would actually be a step backward.
Only 18Gbps 🤔April 23, 2024
