This is the refreshed GeForce RTX 4080 GPU Die from Nvidia
n image of the new AD103-301 silicon, which will be used in the GeForce RTX 4080 graphics card, has been shared on the Chiphell forum. This revised die could allow manufacturers to reduce cost for the GeForce RTX 4080 and increase their margins.
However, it is not expected to improve the performance or power of the graphics card. According to reports, the change was made to the voltage comparator, which is now housed within the GPU, requiring partners to update their PCB designs for custom GeForce RTX 4080 graphics cards.
While it is unclear if there is a significant cost savings associated with the AD103-301 silicon, it could add up over time for manufacturers who produce large numbers of units. The AD103-301 silicon has reportedly been around for a while, and it is possible that it is already being used in some GeForce RTX 4080 graphics cards on the market.

I'd rather the the silicon used in 4060 (Ti) and 4070, as an indication of a release in the near future.

Igor thinks it due to how Nvidia cut the 4090 die down to make this new die for the 4080. He suspects they chopped something in the design they should not have which is why the 4090 isnt getting a new version.
It appears that it hasn't been done "to reduce costs" (it's just a side effect, although the part is said to not actually cost much anyway) and the original chip had a problem with the internal comparator used for fan speed and required an external comparator to work around the problem. The fixed chips don't require it anymore as their internals are working properly.

if i'm not mistaken, initial launch dies had a non-functional comparator so the task required a board side implementation, the new dies have this fixed so the board can have the circuit removed or fused off.
these chips might even have slightly better voltage transients at the same asic quality.

They want to reduce costs? Then think about going back to the form factor that was used for earlier cards that used the same amount of power, or even less. 50% more expensive but 50% larger might sound like a way to promote the cards, but sales suggest it was an idiotic approach.
