According to Neowin the release notes for the latest GCC version 23.03.02.01 lists support for colors of the RTX 4060 Gaming OC 8GB model. Gigabyte has confirmed the memory capcity of the RTX 4070. Its Aero OC RTX 4070 has 12GB VRAM, just like the RTX 4070 Ti. The last gen RTX 3060 had 12GB and 3070/Ti featured 8GB.
Here is a screenshot of the release notes showing the 4060 with 8GB and the 4070 with a 12GB memory buffer.
A report last year suggested that the RTX 4060 will have 36 steaming multiprocessors (SMs) or 4,608 CUDA cores. However, this is still unconfirmed and is unlikely. The laptop variant comes with 3,072 shaders which means the desktop counterpart might have 3,840. The RTX 4070, purportedly features 5,888 CUDA cores.
