NVIDIA tipped to release two GeForce RTX 3070 Ti variants with 8 GB and 16 GB GDDR6X VRAM
More rumours about the upcoming GeForce RTX 3070 Ti have emerged online, and they point to NVIDIA releasing two SKUs. Last week, Videocardz revealed that NVIDIA plans to release the GeForce RTX 3070 Ti on its GA104-400 GPU, presumably the full version of the GA104 that it uses in the RTX 3070 and RTX 3060 Ti. The website added that the GeForce RTX 3070 Ti would have 8 GB of GDDR6X VRAM too, giving the card an edge over its GA104-based siblings.
However, Uniko's Hardware asserts that NVIDIA has developed 8 GB and 16 GB versions of the card. According to its tweet, NVIDIA has sourced MT61K256M32JE memory from Micron, although they did not explain how NVIDIA could offer 8 GB and 16 GB versions of the same card. Videocardz believes that this could be possible if NVIDIA used dual-sided memory, but there have been no indications so far that this will be the case.
MT61K256M32JE memory runs at 19 Gbps by default, which is in line with previous rumours about the GeForce RTX 3070 Ti. Micron's datasheet confirms that the memory is rated for up to 21 Gbps though, while other GDDR6X cards can exceed 20 Gbps without much effort.
If the GeForce RTX 3070 Ti does have GDDR6X VRAM, it would have a much higher memory bandwidth than the RTX 3070 (448 Gbps). The GeForce RTX 3070 Ti is expected to have a 256-bit bus though, so it will not reach the RTX 3080's 760 Gbps bandwidth.
