High-end NVIDIA GeForce RTX 3070 cards to use full GA104 GPU?

We know NVIDIA's Ampere consumer GPU is on the way. It's rumored that the desktop version will be revealed in September and there's still little official information about these chips. Various rumors have hit the web, as well as some photos of a potential board design that may be used by NVIDIA's reference card.

Twitter is abuzz with lots of Ampere rumors and people are paying attention when leakers have previously provided information that turned out to be correct. VideoCardz created an overview of some of the latest leaks. As always, take this with a grain of salt.

Here's a brief overview:

GDDR6X with up to 21Gbps to be used. This seems really high, which makes it a bit hard to believe.

GeForce RTX 3080 to use GA102 instead of GA104 GPU. No NVIDIA x80 series model has the used the generation's big GPU since the GTX 780 Ti. By using the GA102 GPU, NVIDIA has more options to put more memory on its RTX 3080.

GeForce RTX 3080 Founders Edition is rumored to feature a new power connector.

GeForce RTX 3070 series to use the GA104 GPU, with high-end variants using the GA104-400 model. This means the RTX 3070 Ti/SUPER will feature a full GA104 GPU with all CUDA cores enabled. Makes sense if the RTX 3080 uses the GA102.

GeForce RTX 3070 has 220W TGP and RTX 3070 SUPER has 250W TGP

Based on all the leaks and rumors, VideoCardz compiled the following table with possible RTX 30 series specifications:
