Gigabyte now lists as many as six different GeForce RTX 4070 graphics cards models with various memory configurations on its Thai-language website, according to VideoCardz. Nvidia is rumored to formally announce its GeForce RTX 4070 in April, so Gigabyte's listings may be placeholders or even typos since actual specifications of the product may not be finalized.
A Gigabyte game bundle giveaway in Thai language now reportedly lists GeForce RTX 4070 with 10GB, 12GB, and 16GB of GDDR6X memory, including GeForce RTX 4070 Aorus Master 12GB, GeForce RTX 4070 Eagle OC 12GB, GeForce RTX 4070 Gaming OC 10GB, GeForce RTX 4070 Gaming OC 12GB, and GeForce RTX 4070 Gaming OC 16GB. We logged into the Gigabyte Thai website, but couldn't find this giveaway, but presumably it exists as a user shared it with the staff at VideoCardz.
Nvidia's vanilla GeForce RTX 4070 is expected to be based on the AD104 graphics processor with 5888 CUDA cores operating at 1920 MHz – 2475 MHz as well as a 192-bit memory bus. Given that the board has to use 16Gb (2GB) GDDR6X memory chips, the only configurations possible on a 192-bit memory interface are 12GB (using six ICs) and 24GB (using 12 ICs).

|GeForce RTX 4060 Ti||AD106||4352 (?)||8GB 128-bit 18 GT/s GDDR6||160W (?)||<$500?|

For 10GB, an AD104-based product would have to go down to a 160-bit memory interface, which is possible, but which will lower memory bandwidth. Meanwhile, the AD104 physically does not have a 256-bit memory interface to support a 16GB configuration without using an extravagant memory organization.
For now, it looks like Gigabyte listed different versions of GeForce RTX 4070 because Nvidia either considers or considered various configurations of GeForce RTX 4070 product, including a 10GB and a 12GB verson. Meanwhile, it is impossible for an AD104-based product to support 16GB of memory with its 192-bit memory interface without using a fancy memory organization and possibly repeating the GeForce RTX 970 4GB fiasco, at least based on what we know about the AD104.
While all of GeForce RTX 4070 boards with different memory configs might join the ranks of some of the best graphics cards available, it looks like only 12GB version will make it to the market. Still, we will have to wait until later this year (possibly April) to find out.
Though most likely, it could also be a TYPO error on Gigabyte's website, or a placeholder for the upcoming RTX 4060 Ti and RTX 4060 SKUs on a different bus width/VRAM config(despite the model name being displayed as RTX 4070 on Gigabyte's page).
But the most possible explanation would be that Nvidia might have dropped/cancelled some of these planned SKUs, IMO. Because, it's going to get confusing for end users for sure if the RTX 4070 comes out in 3 different VRAM configurations.

However as per one report, AD104-250 & AD104-251 GPUs are virtually the same chip, and the latter isn't going to be featured on the RTX 4060 as we thought so.
Instead, the 251 designated chip will utilize a slightly different circuit board as pointed out by HKEPC, allowing for lower BOM costs (around $1 Less) & also helping to improve the power efficiency slightly. I doubt this will effect the VRAM config though.
I can't wait for the entry-level 4GB GT 4070, for a cool bargain price of $500
Who's to say that a 16GB RTX 4070 would be limited to the same terrible 192-bit bus width? I mean, there's no chance they would do it at this point since Jensen lost his mind and tried to get away with selling a product with a 192-bit RTX class memory bus as the "RTX 4080 12GB" ... But I bet Nvidia's engineers specced their original RTX 4070 design with the same 256-bit bus as every other RTX x070 card.
Look at the massive performance gap between the RTX 4090 and the RTX 4080 16GB. That giant performance hole could easily fit 2-3 intermediate SKUs. I think there's a very good chance that the RTX 4080 16GB was originally designed to be sold as a RTX 4070 16GB.
The way I see it, the holes in their lineup makes a lot more sense if the following late-stage brand changes are assumed:
