Micron's ultra-fast 24 Gbps GDDR6X is now in mass production for next-generation graphics cards

Micron's ready to power Nvidia's RTX 40 series with its latest GDDR6X memory modules

Creating next-generation computational technologies is a difficult process, not only does companies like AMD, Intel, or Nvidia need to develop the silicon behind each generation of innovations, they also need to rely on a myriad of hardware partners to ensure that their technologies move in step. 

High-end processors and graphics cards require fast memory subsystems to achieve peak performance, and Nvidia relies heavily on Micron to develop memory solutions that can deliver enough bandwidth to get the best performance out of their latest graphics cards. 

Like its RTX 30 series of Ampere based products, Nvidia's RTX 40 series of graphics cards are expected to utilise Micron's ultra-fast GDDR6X memory technology. Thankfully, Micron has managed to produce faster GDDR6X memory modules following the launch of Nvidia's RTX 30 series, offering customers memory speeds of up to 24 Gbps. 

Micron's website has confirmed that the company is now mass producing 21 Gbps and 24 Gbps GDDR6X memory modules, offering their 21 Gbps modules in both 8Gb (1GB) and 16Gb (2GB) capacities. Micron's faster 24 Gbps GDDR6X modules only appear to be available in 16Gb (2GB) capacities, which likely means that these speeds will only be used for flagship-level Nvidia products.

For most of Nvidia's GDDR6X based RTX 30 series products, Nvidia utilised 19 Gbps GDDR6X memory modules. For their RTX 40 series, Nvidia is expected to mostly use 21 Gbps GDDR6X memory modules, which offer users a 10.5% increase in memory bandwidth. In cases where 24 Gbps memory is used instead of 19 Gbps modules, memory bandwidth increases of 26.3% will be delivered. 

When combined with cache-based changes and other architectural enhancements for Nvidia's RTX 40 series, the company's next-generation graphics cards are expected to deliver a lot more effective bandwidth to their customers. That said, Nvidia has not discussed their RTX 40 series in great detail, so this is merely speculation.
