MSI GeForce RTX 3070 Ti SUPRIM and VENTUS 3X pictured, GDDR6X confirmed - VideoCardz.com
 
MSI will be launching at least two RTX 3070 Ti models, featuring the exact same design as RTX 3070 non-Ti. The SUPRIM X and Ventus 3X are to feature newer Ampere GA104-400 GPU with all 6144 CUDA cores enabled. These graphics cards will be equipped with 8GB of GDDR6X memory, which is an upgrade over GDDR6 on RTX 3070 non-Ti. MSI RTX 3070 Ti Ventus 3X OC is clocked at 1800 MHz, which is 45 MHz higher than RTX 3070 Ventus 3X OC. According to our information, this model will be equipped with dual 8-pin power connectors and carry a TDP of 290W, but at this moment we don’t the reference TDP of this SKU.
 
The SUPRIM X feature RTX 3070 non-Ti design, which is also based on GA104 GPU. The specifications of this model are not yet determined so there is nothing more to share at this moment.
 
NVIDIA RTX 3070 Ti is now scheduled to launch on June 10th. The graphics card will be announced along with RTX 3080 Ti on May 31st during Computex 2021 keynote.
 
I still don't see how you will be able to buy one. 
 

While several of the specs remain speculative, according to most leaks the core count will not be significantly higher than the 3070.
Theoretically it will give us the closest observable comparison between GDDR6 and GDDR6X. Looking forward to seeing the benchmarks.

Perhaps will can buy one through EVGA? Seriously.

Very pretty
