Pictured is the PCB for the NVIDIA GeForce RTX 4080 Founders Edition, revealing AD103 Silicon.
The rectangular die and fiberglass substrate of the AD103 silicon are similar in size to those of earlier NVIDIA GPUs with 256-bit wide memory interfaces, such the GA104. The smaller AD104 GPU is likely pin-compatible with the AD103 GPU, at least in terms of substrate size, hence the RTX 4080’s...
