Meh, I was hesitating to post this news. As most if this is unsubstantiated guesswork and thus chatter and rumours. The level of leaks on Twitter should be dealt with caution.

New chatter about the upcoming GeForce 30 series is here again. The activity in twitter in regards to leaks has been substantial.

In his latest tweet, kopite7kimi's mentions the GeForce RTX 3070 (Ti / SUPER, etc.) would use the GA104-300 GPU. it would be based on 2944 Shader Cores; there also would be a beefed-up version under the Ti suffix. The GeForce RTX 3070 Ti would house a GA104-400 ASIC with 3072 shader cores. Both would see 8 GB of the latest fastest GDDR6X memory. Memory bandwidth could be around 512 GB/s. The Nvidia GeForce RTX 3070 would be around $400 with performance that would be comparable to a GeForce RTX 2080 SUPER, while the Nvidia GeForce RTX 3070 Ti could be about $500 with performance around that of the GeForce RTX 2080. You.

Remember that kopite7kimi's mentions no source, so it remains to be seen if this is guesswork or substantiated data. As such, treat this info like that. 

Rumor: Pricing and specs for upcoming GeForce RTX 3070 Ti and RTX 3070?
