Apparently, specifications for NVIDIA's upcoming RTX 30-series mobile solutions have been made public. According to Videocardz via Notebookcheck, NVIDIA will introduce three mobile versions of their RTX 30-series graphics cards in the form of the RTX 3080, RTX 3070 and RTX 3060. Like past NVIDIA mobile solutions, these won't directly correspond, hardware-wise, to their desktop counterparts; NVIDIA has the habit of downgrading their mobile solutions' chips compared to their desktop counterparts. According to the leaked specifications, this means the mobile RTX 3080 will maker use of the company's GA-104 chip, instead of the GA-102 silicon found on desktop versions of the card.
The mobile RTX 3080 should thus feature a total of 6,144 CUDA cores, as present in the fully-enabled GA-104 chip (compare that to the 5,888 CUDA cores available on the desktop RTX 3070, and the 8,704 CUDA cores available on the RTX 3080). These CUDA cores would be clocked at up to 1.7 GHz. The memory bus should also see a cut down to 256-bit, which would allow NVIDIA to distribute as many as 4 versions of the RTX 3080 mobile: Max-Q (TGP 80-90 W), Max-P (TGP 115-150 W), with either 8 GB or 16 GB of GDDR6 memory. The RTX 3070 mobile keeps the GA-104 chip, 256-bit bus and GDDR6 memory subsystem (apparently with only 8 GB memory pool available), but further cuts down CUDA cores to 5,120 (Max-Q TGP 80-90 W, Max-P TGP 115-150 W). Finally, the RTX 3060 mobile should make use of the GA106 chip, set up with 3,072 available CUDA cores and a 192-bit memory bus across its 6 GB of GDDR6 VRAM pool (Max-Q TGP 60-70 W), Max-P (TGP 80-115 W). Expect these specs to be confirmed (or not) come January 12th.
