The upcoming NVIDIA GeForce RTX 30 Series Graphics Cards, based on the next-gen Ampere Architecture, will have GDDR6X Memory modules. This next-generation VRAM is expected to confidently break the 1TB/s bandwidth barrier that none of the previous generation Graphics Cards have managed to even reach. The current-generation GDDR5 memory can barely reach 800 GB/s.
NVIDIA’s long-term partner and memory module supplier Micron, has confirmed that the Graphics Cards maker is going with GDDR6X memory for its premium NVIDIA GeForce RTX 3090. Micron has supplied memory modules for GeForce graphics cards for several years, and the company has confidently developed and manufactured the next generation of memory modules on priority specifically for NVIDIA.
NVIDIA GeForce RTX 3090 Ampere Graphics Card To Feature 12GB GDDR6X Memory?
Micron confirmed that GeForce RTX 3090 will sport memory based on the next-generation GDDR6X technology. In fact, NVIDIA GeForce RTX 3090 Graphics Card is listed on the Micron website with 12GB GDDR6X memory. The memory module manufacturer is confident that GeForce RTX 3090 will be able to break the 1 TB/s barrier. The official revelation reads as follows:
“Micron GDDR6X is the world’s fastest graphics memory, delivering legendary performance to help drive ray tracing, shadow mapping, and silky-smooth animation for an immersive PC gaming experience.”“In the Summer of 2020, Micron announced the next evolution of Ultra-Bandwidth Solutions in GDDR6X. Working closely with NVIDIA on their Ampere generation of graphics cards, Micron’s 8Gb GDDR6X will deliver up to 21Gb/s (data rate per pin) in 2020. At 21Gb/s, a graphic card with 12pcs of GDDR6X will be able to break the 1TB/s of system bandwidth barrier! Micron’s roadmap also highlights the potential for a 16Gb GDDR6X in 2021 with the ability to reach up to 24Gb/s. GDDR6X is powered by a revolutionary new PAM4 modulation technology for Ultra-Bandwidth Solutions. PAM4 has the potential to drive even more improvements in data rate.”There were several reports about the use of GDDR6 Memory within the upcoming Ampere-based NVIDIA GeForce RTX 30 Series of Graphics Card. However, previous benchmark leaks had failed to identify the type of memory used in engineering samples or early prototypes of next-gen NVIDIA Graphics Cards. This strongly indicated the use of next-gen memory. Still, not a single memory manufacturer confirmed the same.
NVIDIA GeForce RTX 3090 Ampere Graphics Card Specifications And Features:
Micron has only confirmed the use of 12GB of GDDR6X memory modules on a single variant of the NVIDIA GeForce RTX 3090. Previous reports, however, have indicated this premium or high-end Graphics Cards would pack 10 GB, 20 GB, or even 24 GB memory.
With the power of the GDDR6X memory, the NVIDIA GeForce RTX 3090 Graphics Card could stay between 912 and 1008 GB/s. However, to achieve 1TB/s bandwidth, the graphics card would require a clock speed of 21 Gbps and a memory bus of 384-bit. The estimation indicates NVIDIA hasn’t yet finalized the speed on the premium Graphics Card. Nonetheless, the card should confidently reach speeds in excess of 19 Gbps per pin.The NVIDIA GeForce RTX 3090 is now believed to be the fastest Graphics Card from the NVIDIA Ampere-based lineup. It will reportedly feature the GA102-300-A1 GPU which will have 5248 CUDA cores or 82 SMs. Buyers can expect at least a 20 percent boost in performance over the GeForce RTX 2080 Ti.
There will be at least three high-end GeForce RTX graphics cards on announcement day on 1st September. Hence, there’s still ample time for more leaks to surface and NVIDIA is known to make some last-minute modifications or tweaks.
