However, the engraving on the chip has been changed again to GA102-300-A1, as is to be expected for a GeForce RTX 3090. The GPU-Z screenshot then shows a GeForce RTX 3090 as expected, but anything else would have been really surprising.
Now it would be interesting to know why the engraving was originally GA102-250-KD-A1 and was changed to GA102-300-A1. This would mean an “upgrade”, which would actually be rather unusual, because possibly partially defective chips are rather reused for smaller models. In any case, the GPU was manufactured in the 49th week of last year, which began on November 30, 2020.

* according to the latest rumors
The GA102-300 GPU with its 82 SMs is used on the GeForce RTX 3090. According to the latest rumors, the GeForce RTX 3080 Ti now uses the GA102-225 GPU with 80 SMs, while at the end of 2020 there was talk of the GA102-250-KD-A1 GPU with 78 SMs for the GeForce RTX 3080 Ti. For comparison, the GeForce RTX 3080 with the GA102-200-KD-A1-GPU and 68 SMs as well as the only 320-bit wide memory interface.
There have been several rumors about the GeForce RTX 3080 Ti in the past few weeks. A publication in April was initially suspected. The latest reports point more towards May. A GeForce RTX 3070 Ti will also be available in the coming weeks.

The second fastest amp model should have 10,240 FP32 processing units and, just like the GeForce RTX 3090, use a 384-bit wide memory interface, so that NVIDIA could use 12 GB of graphics memory here – 2 GB more than the GeForce RTX 3080 That doesn’t satisfy everyone either, but the 24 GB of the GeForce RTX 3090 are probably out of reach for such a card. Based on the previously assumed expansion stage with 80 SMs, the GeForce RTX 3080 Ti would come very close to the GeForce RTX 3090. The mentioned memory expansion would be a big difference. There are also many inconsistencies with the GeForce RTX 3080 Ti, and not just for the expected release date in May.
Finally, thanks again to isoO, who provided us with the pictures on his card so that we could create this message in the first place.
