It looks like 12 GB will be the standard memory size for the NVIDIA GeForce RTX 4070 graphics card the company plans to launch in mid-April 2023. It is very likely that the card has 12 GB of memory across the 192-bit memory bus width of the "AD104" silicon the SKU is based on. The RTX 4070 is already heavily cut down from the RTX 4070 Ti that maxes out the "AD104," with the upcoming SKU featuring just 5,888 CUDA cores, compared to the 7,680 of the RTX 4070 Ti. The memory sub-system, however, could see NVIDIA use the same 21 Gbps-rated GDDR6X memory chips, which across the 192-bit memory interface, produce 504 GB/s of memory bandwidth. Confirmation of the memory size came from regulatory filings of several upcoming custom-design RTX 4070 board models by MSI and GIGABYTE, with the Eurasian Economic Commission (EEC), and Korean NRRA.
