NVIDIA GeForce RTX 4080 graphics cards receive a newer GPU SKU, which changes the requirement for PCB design and is expected to lower manufacturing costs. 

To date, the AD103-300-A1 SKU has been distributed by the company to power GeForce RTX 4080 graphics cards. A new AD103-301 SKU will, however, be used to power the RTX 4080 cards the company intends to ship to its AIBs and possibly use in the reference design. The GPU performance and power envelope should remain unchanged with the 301 update.The ‘251’ GPU will enter mass production a few weeks after ‘250’, and it will require ‘a few less components’, claims our source. In the end this should lower the cost of the GPU, but not significantly.
