Micron has disclosed promising efficiency metrics for its cutting-edge graphics reminiscence, sparking optimism for the prospects of future graphics cards should these numbers prove accurate.
The corporation asserts that its GDDR7 VRAM technology will deliver up to a 30% boost in gaming performance, with this purported improvement applicable both to games heavily reliant on ray tracing and those relying solely on traditional rasterization techniques. Will Nvidia’s impending RTX 50 series, touted for harnessing the power of GDDR7 memory, ultimately deliver a transformative upgrade that surpasses initial expectations?
Micron initially shared information on its newly unveiled GDDR7 modules, which boast speeds of up to 32Gb/s, directly comparing them to its existing GDDR6 memory that tops out at 20GB/s. While GDDR6X memory can reach up to 24 GB/s per pin for comparability, this marks a significant improvement regardless; however, it’s essential to note that GDDR7 memory will start at 28Gb/s.
Micron highlights several key benefits of its GDDR7 technology. Startingly, bandwidth increases by up to 60% when utilizing the highest-capacity GDDR6 or GDDR7 memory modules, with GDDR7 capable of achieving a remarkable system bandwidth exceeding 1.5 terabytes per second.
Micron highlights another significant advantage of GDDR7: a substantial boost in energy efficiency. According to the company, this newer memory standard is up to 50% more power-efficient compared to its predecessors, with its innovative sleep modes capable of slashing energy consumption by as much as 70% when the device is in standby mode. By streamlining operations, Micron successfully reduced response times by up to 20%, a significant benefit for generative AI applications.

While first-party benchmarks are useful, it’s always crucial to approach them with a healthy dose of skepticism. Despite their complexity, certain numbers remain impossible to deny. While the exact impact of a 30% boost in frames per second is uncertain, we can confidently assert that the fastest GDDR7 memory will yield a substantial increase in memory bandwidth.
Micron’s comparison highlights a setup featuring 12 GDDR7 built-in circuits (ICs) and a 384-bit memory interface, which surpasses an actual match from the previous era, thereby pushing bandwidth beyond the 1.5TB/s threshold. Meanwhile, the RTX 4090 boasts faster GDDR6X memory that reaches speeds of up to 21Gbps, ultimately peaking at slightly above 1 terabyte per second. The good points are indeed evident.
Nvidia’s prospects appear to have received a significant boost. Current speculation surrounding the specifications of the forthcoming RTX 50-series is underwhelming, with significant advancements reserved for the flagship RTX 5090 model, while the lower-end variants are expected to see more modest performance enhancements. While matching CUDA core counts might evoke rapid recall, it’s actually faster VRAM that propels GPUs forward in terms of fps, even when their core counts are similar.
In reality, that 30% allocation won’t actually utilize each GPU individually. However, a slim memory bus can still hinder even the most potent VRAM, as evident in GPUs such as the Nvidia RTX 4060 Ti with its 16GB capacity. Among the RTX 40-series offerings, Nvidia conservatively allocated memory resources across many graphics cards, retaining a consistent approach to memory allocation and interface architecture. While the same technology is used in the RTX 50-series, a significant improvement comes with the introduction of GDDR7 memory, even if only a 30% boost is reserved for GPUs like the RTX 5090.
Micron’s newly released reminiscence modules appear to be quite impressive, with the possibility that they will debut on NVIDIA’s forthcoming graphics cards. According to recent reports, AMD is expected to stick with GDDR6 memory technology for its upcoming RDNA 4 graphics architecture. By integrating AI-powered technology into its GPUs, this could potentially give Nvidia a competitive advantage across multiple fronts.
