"Why NVIDIA would make RTX 4070 using the significantly larger "AD103" silicon, is anyone's guess—the company probably has a stash of chips that are good enough to match the specs of the RTX 4070, so it would make sense to harvest the RTX 4070 out of them, which could sell for at least $500 in the market. This also opens up the possibility of RTX 4070 SUPER cards based on this chip, all NVIDIA has to do is dial up the SM count to 56, and increase the L2 cache available to 48 MB. How the switch to AD103 affects power and thermals, is an interesting thing to look out for.

Our next update of TechPowerUp GPU-Z will be able to correctly detect RTX 4070 cards based on AD103 chips."

Those were probably initially for a China exclusive version of some workstation card they can no longer sell there and since the work was already done might as well firmware gimp it and send it out the door as a 4070.

Old news, saw it weeks ago :), but they're just defective chips being repurposed. It's not some big mystery.

I mean Nvidia might as well use them all up while they can, the consumer 5080 and 5090 are supposedly launching in Q4 this year and Nvidia doesn't want leftover stock on the shelves, and honestly neither do AIBs, it eats into their profits if they have to issue discounts on last gen to clear them out.

Exactly.
 
Which brands are selling these? I wonder if there is any difference in OC headroom.
 
This was the "see it really was a 4080 and not just a renamed 4070 to try and get more money out of it!" maneuver?
