GDDR7 memory to come in 2GB to 8GB capacity

The new memory standard is faster and has more capacity options.

According to NVIDIA hardware leaker “Kopite7kimi”, the first products using GDDR7 memory will be sticking to the minimum density of 16 Gb (2GB) per module, the same capacity as currently utilized by GDDR6X models.

At its introduction, the 2GB GDDR7 capacity will already be an upgrade over GDDR6, which debuted with 8 Gb (1GB) density and was extensively used by first graphics cards using this technology, such as GeForce RTX 20 and later RTX 30 series. Worth reminding that the lack of 2GB GDDR6(X) modules was the reason RTX 3090 required 24 modules on both sides of the PCB.

The 16Gb density is the lowest density as defined by JEDEC GDDR7 specs. It’s the same capacity as currently used by RTX 40 series. However, what’s important to note is that JEDEC specs also enable 24Gb (3GB), 32Gb (4GB), 48Gb (6GB) and even 64Gb (8GB) densities. Such non-standard densities are not a new thing, even GDDR6 had 12 Gb (1.5GB) capacity listed, but it was never mass-produced.

In the case of GDDR7, Micron actually does plan to make 3GB GDDR7 modules. This company developed the GDDR5X and GDDR6X custom variants for NVIDIA, which may suggest that NVIDIA will be exploring new capacity configurations in future GPUs.

The first products expected to feature GDDR7 memory are the GeForce RTX 50 series based on Blackwell architecture and AMD Radeon RX 8000 series based on RDNA4. Unfortunately, neither has a release date; however, the hope is that both product series will be unveiled by the end of this year.
