In an unexpected twist, NVIDIA has “unlaunched” the GeForce RTX 4080 12GB after widespread criticism from enthusiasts and media alike. Unlike the 16GB variant, it was derived from the AD104 die, which is notably smaller and less potent than the AD103 core powering its sibling. In addition to the memory buffer, we’re talking about fewer core counts (9,728->7,680 FP32), a slimmer bus (256-bit->192-bit), slower GDDR6X chips (23Gbps->21Gbps), as well as a much smaller L2 cache reserve (64MB->48MB).

In a blog post, NVIDIA had the following to say:
The RTX 4080 12GB is a fantastic graphics card, but it’s not named right. Having two GPUs with the 4080 designation is confusing.
So, we’re pressing the “unlaunch” button on the 4080 12GB. The RTX 4080 16GB is amazing and on track to delight gamers everywhere on November 16th.
If the lines around the block and enthusiasm for the 4090 is any indication, the reception for the 4080 will be awesome.NVIDIA
It looks like Team Green won’t be entirely scrapping the RTX 4080 12GB but launching it as a separate SKU, likely the RTX 4070 Ti. It’s unclear if the price will be reduced, but given that this is a relatively mainstream GPU, anything higher than $699 would be too much. From now on, GeForce RTX 4080 will refer to the 16GB variant set to launch next month at an MSRP of $1,199.
