A prototype of Nvidia's GeForce RTX 4090 Ti was found on a Chinese marketplace. The card, which never entered serial production, features 18,176 CUDA cores – 11% more than the retail RTX 4090 – along with 192 ROPs and 568 TMUs, matching earlier leaks.
For comparison, the serial RTX 4090 has 16,384 CUDA cores, 512 TMUs and 176 ROPs. The prototype's specifications are similar to those of the RTX 6000 Ada, indicating Nvidia had prepared a more powerful variant before canceling the series launch.
