Micron Roadmap Details GDDR7 Memory For Next-Gen NVIDIA GPUs: Up To 24Gb & 32 Gbps Dies In 2024, 24Gb+ & 36 Gbps In 2026

wccftech.com:

Micron has published its latest roadmap which details its upcoming memory technologies including GDDR7 for next-gen NVIDIA GPUs.

NVIDIA has been selecting Micron's GDDR solutions for its graphics cards for quite some time. The green team first co-developed the GDDR5X standard with Micron with its GeForce 10 series cards & currently uses the fastest GDDR6X modules for its latest RTX 40 graphics cards. The company also uses standard GDDR6 chips in its budget-friendly & mainstream designs. Now, Micron has released its latest roadmap which gives us a glimpse of what to expect in the future.

Starting with the initial GDDR7 Graphics DRAM from Micron, we are looking at 16Gb & 24Gb DRAM dies. A 24 Gb module will give us 3 GB VRAM capacity per die versus the 2 GB VRAM capacity on a single 16Gb die. The memory modules will also operate at higher clock speeds of 32 Gbps, offering up to 128 GB/s bandwidth per module. A lowly 128-bit solution will be able to output 512 GB/s of bandwidth. For comparison, the GeForce RTX 4060 with a 128-bit bus GDDR6 interface outputs 272 GB/s of bandwidth so GDDR7 offers nearly twice as much bandwidth.

The first generation GDDR7 memory modules are expected by the mid of 2024 which also hints that we can expect NVIDIA's next-generation lineup around the same time. The company plans on refreshing its GeForce RTX 40 portfolio with the new "SUPER" family with an unveiling planned for CES 2024. Those could also benefit from the higher speeds offered by the existing GDDR6X DRAM (up to 24 Gbps).

Following is the bandwidth the 32 Gbps pin speeds would offer across multiple bus configurations:

Moving forward, Micron will further upgrade its GDDR7 memory with even higher speeds and more capacities. This will be made
