AMD to Use 18 Gbps GDDR6 Memory in RDNA 4 Radeon RX 8000 GPUs

Despite industry trends towards faster GDDR7, AMD opts for the existing GDDR6 standard to enhance affordability and power efficiency in its upcoming graphics cards.

AMD's next-generation RDNA 4 Radeon RX 8000 series will continue using 18 Gbps GDDR6 memory, foregoing the newer GDDR7.
The decision allows AMD to target the mainstream and entry-level market segments more competitively.
NVIDIA, in contrast, is moving to GDDR7 for its high-end Blackwell and GeForce RTX 50 Series, starting with 28 Gbps speeds.
AMD may leverage enhanced Infinity Cache designs to compensate for the slower memory speed in RDNA 4 GPUs.
Early launches of the Radeon RX 8800 XT, 8700 XT, and 8600 XT are anticipated before the end of the year.
