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.
This is the refreshed GeForce RTX 4080 GPU Die from Nvidia
