An interstring post on the web shows that Nvidia has been shuffling around GPUs a little. One use purchased the flagship RTX 3090 in the Founders Edition and wanted to apply water cooling. But then when the GPU became visible, he noticed the laser engraving on the GPU was initially GA102-250-KD-A1 - a GPU intended for the GeForce RTX 3080 Ti.
That GeForce RTX 3080 Ti is now said to be based on the GA102-225 GPU. Now the remarkable thing, the meantime. The engraving on the chip has been changed back to GA102-300-A1, as is to be expected for a GeForce RTX 3090. So in short, we all know it's the same GPU series, just reconfigured. However, NVIDIA had planned GA102-250-KD-A1, and then has repurposed the same GPU to GA102-300-A1. And to actually see a changed laser etch not the chip, well that is remarkable.
