Nvidia’s New RTX 40 GPU Dies Seem to Fix Bug, Likely Won’t Cut Price

Earlier this week, it was revealed that Nvidia has started using new revisions of their AD103 and AD104 graphics processors in their GeForce RTX 4080 and GeForce RTX 4070 add-in boards (AIBs).Some thought the new revisions would reduce power consumption and improve yields, potentially impacting the cost of the actual card. Igor’s laboratory claims that newer GPUs only have a built-in comparator for the fan, which has little impact on the AIB cost of the bill of materials (BOM).

Nvidia’s AD103-300 (used in the GeForce RTX 4080) and AD104-250 (used in the GeForce RTX 4070 and RTX 4070 Ti) graphics processing units require graphics card manufacturers to add a comparison circuit.Fan PWM signal with actual value according to Igor’s laboratoryThe new AD104-251 and AD103-301 integrate the comparator into the GPU, so the AIB no longer needs to have an external comparator circuit.
