https://www.kitguru.net/components/graphic-cards/joao-silva/nvidia-rtx-3060-reportedly-launching-in-january-with-a-12gb-configuration/ The RTX 3050Ti was initially planned for a February release, but as reported by
VideoCardz, it’s now scheduled for a release in January, alongside the other upcoming RTX 30 series SKUs. Regarding the board used on the RTX 3060, 3050Ti, and 3050, it will be the same as the one used on the RTX 3060Ti, the PG190. This board will be compatible with both the GA104 GPU (RTX 3060Ti) and the GA106 GPU, which will be used on the RTX 3060, 3050Ti, and 3050.
One interesting thing to note is that the RTX 3060 was apparently planned to feature the PG190 SKU 30 with 6GB@14Gbps, but it was then updated to the PG190 SKU 40 featuring 6GB@16Gbps. The last update made to the SKU now includes the PG190 SKU 50, which is equipped with 12GB@16Gbps. If this information proves to be true, we will see the mid-range RTX 3060 featuring more VRAM than the RTX 3060Ti (8GB), the RTX 3070 (8GB) and the RTX 3080 (10GB).
On another note, this same report also claims that the RTX 3050Ti is expected to feature 6GB across a 192-bit bus, complementing what we already knew from this SKU, which should be using the GA106GPU with 3584 CUDA cores.
Personally if the rumors are true the mid-range NVIDIA SKUs seem a little strange to me.
