NVIDIA GeForce RTX 3090 Ti confirmed to feature Micron’s 21 Gbps GDDR6X memory

NVIDIA GeForce RTX 3090 Ti gets Micron GDDR6X memory

Ultra-fast memory for NVIDIA’s upcoming flagship.

The GeForce RTX 3090 Ti is to feature 21 Gbps memory from Micron. The Taiwanese media outlet “Uniko’s Hardware”, which often shares information on unreleased products has now provided the exact code from Micron’s GDDR6X memory catalog. According to this information, a memory codenamed “MT61K512M32KPA-21U” is to be used for RTX 3090 Ti. The code appears to confirm it will be a 21 Gbps bandwidth per module.

Apart from the speed, the card is also the first product to utilize 16Gb (2GB) modules based on GDDR6X technology. NVIDIA has thus far been unable to provide this 2GB GDDR6X memory variant to any of its products because such modules simply did not exist. This led the company to use GDDR6 memory on its workstation products that require high-capacity frame buffers and as many as 24 modules on its current flagship, the RTX 3090 non-Ti.

With the upcoming Ti model, NVIDIA will be able to limit the number of modules to 12, this should simplify the design of the card by not requiring an actively cooled backplate (the RTX 3090 has half of the modules located on the backside). However, the requirement of active back cooling may still prevail because the card will be a true power hog. According to the rumors, the RTX 3090 Ti is to have a default TDP of 450W, over 100W more than the non-Ti model.

NVIDIA RTX 3090 Ti is the first GeForce card to feature full GA102 GPU with 10752 CUDA cores. Thanks to the faster memory and 384-bit wide memory bus, the card will be able to cross 1 TB/s of bandwidth for the time in GeForce history.

The card is now expected to launch in January, following the launch of RTX 3080 12GB and RTX 3070 Ti 16GB.
