Good decision from NVIDIA: the RTX 4080 12GB won't be launched because the name is confusing (the RTX 4080 12GB will be likely launched as the RTX 4070 in the future...):
QuoteThe 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.
