In the context of the virtual Consumer Electronics Show CES 2021, Nvidia has also announced another Ampere PCIe graphics card that is somewhat out of the ordinary, in addition to many mobile solutions.
In contrast to the current, far more expensive 8GB cards with Ampere chips (RTX 3060 Ti, RTX 3070 and RTX 3080), the RTX3060 without Ti comes with a whopping 12GB and is said to cost "only" 320 euros. In return, its DDR6 memory interface has been trimmed to 192 bits, which was also typical for earlier Nvidia model series in this price range.
In the best case, the RTX3060 12G only achieves a data throughput of 336 GB/s, while its 256-bit siblings achieve significantly more with 448 GB/s. In the past, our correlations between the two are not so great.
In the past, the memory throughput in our tests correlated particularly with the GPU effect performance under Resolve. For this reason, this mid-range card might not be a hot tip for video editing despite the larger memory.
However, 
Videocardz claims -without naming a source- that the card will also be equipped with slightly faster memory (16 instead of 14 Gbps), which would mean 384 GByte/s after all.
However, we will have to be patient until we learn more about this. The RTX3060 with 12 GB is not due to be delivered until the end of February. What the availability will look like then is another matter...
