In a recent technology brief Micron has confirmed that it has been developing GDDR6X memory for NVIDIA’s next-generation Ampere graphics card lineup. Micron has been a memory module supplier for the Geforce graphics cards, and this new partnership with Nvidia takes things to a whole new level, by bringing GDDR6X memory type support.
The GeForce RTX 3090 graphics card is being listed on the Micron website with 12GB GDDR6X memory, so we can expect the bandwidth to be between 912 to 1008 GB/s. The clock speed is not yet set, but it should be between 19 and 21 Gbps. But to achieve 1TB/s bandwidth, the memory bus width needs to 384-bit wide.
The NVIDIA GeForce RTX 3090 is expected to feature the ‘GA102-300’ GPU die having 5248 CUDA cores, but this hasn’t been fully confirmed yet.
Despite Micron claiming the RTX 3090 would launch with 12 GB GDDR6X memory; there have been numerous leaks before pointing to a 22, 20, and even a 16GB configuration. This leak from Micron however confirms the flagship Ampere GPU is named as RTX 3090, and the RTX 30 series nomenclature is indeed correct. It also confirms the RTX 3090 would support up to 21 Gbps memory modules with bandwidth up to 1 TB/s.
Nvidia is hosting a Geforce Special Event on September 1st, and we expect the Green team to announce the next-gen Ampere Gaming GPU lineup, aka the RTX 30 series.
To quote Micron’s press statement:
“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 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.”
Hello, my name is NICK Richardson. I’m an avid PC and tech fan since the good old days of RIVA TNT2, and 3DFX interactive “Voodoo” gaming cards. I love playing mostly First-person shooters, and I’m a die-hard fan of this FPS genre, since the good ‘old Doom and Wolfenstein days.
MUSIC has always been my passion/roots, but I started gaming “casually” when I was young on Nvidia’s GeForce3 series of cards. I’m by no means an avid or a hardcore gamer though, but I just love stuff related to the PC, Games, and technology in general. I’ve been involved with many indie Metal bands worldwide, and have helped them promote their albums in record labels. I’m a very broad-minded down to earth guy. MUSIC is my inner expression, and soul.
