According to available information, it looks like AMD could offer two different models of Radeon RX 6700 XT graphics cards, each with a different TGP.
The news comes from YouTube Coretex, whose sources point to ASIC A and ASIC B variants of the GPU, where ASIC A will offer up to 230W while ASIC B will offer TGP up to 189W. This will most likely be the difference between the reference model Radeon RX 6700 XT graphics card and the customized version offered by other manufacturers.

The Radeon RX 6700 XT is expected to offer a solid performance improvement of 20-25% over the RX 5700 XT video card. The new GPU has 12GB of GDDR6 video memory, with faster 16Gbps throughput.
There will also be a standard Radeon RX 6700 graphics card variant (without the XT in the name), which is expected during April with 6GB of VRAM and the same 16Gbps memory throughput.
