NVIDIA Turned the RTX 4070 into the RTX 4080 Earlier this year, Confusing Board Partners and Gamers [Rumor]

After the embarrassing “unlaunch” of the GeForce RTX 4080 12GB, the Ada Lovelace lineup looks more like a one-man army than a family. The RTX 4090 is a solid GPU priced at $1,599 (a little on the high side), and then you have the RTX 4080 16GB, which is half as fast but costs $1,199 (just 25% cheaper). Meanwhile, the scraped 12GB variant (likely launching as the RTX 4070 Ti) @ $699-799 is slower than the RTX 3090 Ti and on par with the RTX 3080 Ti.

Well, it turns out that NVIDIA had completely different plans for the RTX 4080 and 4070 at the beginning:

According to Tom from MLID, board partners were told that the AD103 die that now powers the RTX 4080 16GB was supposed to become RTX 4070, much like the previous generation. That means NVIDIA nuked the original RTX 4080 (based on the AD102) and promoted the 4070 as a replacement with 20-25% less performance. This would align with what various insiders on Twitter have been claiming over the past year and explain why there is such a massive delta between the RTX 4080 and 4090.
