The model seems based on a full TU107 GPU with 14 CUs, which results in 896 CUDA cores if there have been no architectural changes:
The new SKU is listed with 14 Compute Units, which means 896 CUDA Cores, that’s if the architecture has not changed. After all, entry-level GPUs have no need for RT or Tensor cores. The free space could easily be used for more cores or even smaller die.We will probably learn more in January.
The clock speed of 1.56 GHz points towards GDDR5 memory. This model would offer up to 4 GB of capacity.
