NVIDIA & AMD To Utilize 16 Gb Dies on First-Gen GDDR7 GPUs, 2 GB Memory Capacity & 32 Gbps Speeds

wccftech.com:

The first generation of NVIDIA & AMD GPUs to utilize GDDR7 memory are most likely going to stick with 16 Gb dies for 2 GB VRAM capacities.

First Wave of GDDR7 Memory-Powered GPUs From NVIDIA & AMD To Use 16 Gb Dies, Offering 2 GB Capacity & 32 Gbps Pin Speeds Per Module

The news comes from kopite7kimi, who disclosed that the first iteration of GPUs from NVIDIA and AMD with GDDR7 memory will come with a 16 Gb density, meaning that the minimum capacity we will see for the next-generation standard is 2 GB of VRAM. For comparison, the GDDR6 era kicked off with 8 Gb dies offering 1 GB VRAM capacity per module. We have reiterated this in an earlier post, where JEDEC defined the GDDR7 standard as a whole.

For a quick recap on GDDR7, up until now, we have seen solutions by Samsung & Micron, with both aiming for 32 Gbps pin speeds and 16 Gb dies as well. Micron has also teased 24 Gb & 24 Gb+ dies for the future. With 24 Gb modules, you can get a maximum of 3 GB VRAM per die, and with 24 Gb+ (32 Gb or higher), you can get 4 GB+ VRAM capacities. These higher density dies are likely not going to come this early as GDDR7 has yet to roll out and it will take time for the standard to hit maturity level to allow such capabilities but eventually, by 2026-2028, we will see the rollout of higher VRAM offerings for GPUs.

Following is the maximum bandwidth and memory capacity the 16 Gb dies + 32 Gbps pin speeds would offer across multiple bus configurations:

• 128-bit @ 32 Gbps: 512 GB/s (8 GB)
• 192-bit @ 32 Gbps: 768 GB/s (12 GB)
• 256-bit @ 32 Gbps: 1024 GB/s (16 GB)
• 320-bit @ 32 Gbps: 1280 GB/s (20 GB)
• 384-bit @ 32 Gbps: 1536 GB/s (24 GB)
• 512-bit @ 32 Gbps: 2048 GB/s (32 GB)

2 Gb memory densities would mean that the first iteration of GDDR7 GPUs from NVIDIA and AMD will likely stick with the same memory capacities that we got on current-gen chips. For those who were
