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

Earlier this week it transpired that Nvidia had begun to use new revisions of its AD103 and AD104 graphics processors for GeForce RTX 4080 and GeForce RTX 4070 add-in-boards (AIBs). Some thought the new revisions might reduce power consumption and/or increase yields, which could affect costs of actual cards. But Igor's Lab claims that the new GPUs only have a built-in comparator for fans, which will have little effect on bill-of-materials (BOM) AIB costs. 

Nvidia's AD103-300 (used for GeForce RTX 4080) and AD104-250 (used for GeForce RTX 4070 and RTX 4070 Ti) graphics processing units require makers of graphics cards to add a comparator circuit which ensures that fans rotate at the right speed by comparing fans PWM signal with actual values, according to Igor's Lab. The new AD104-251 and AD103-301 integrate the comparator into the GPU, which means that AIBs no longer need to carry external comparator circuitry. 

At the end of the day, all GeForce RTX 4070 Ti and GeForce RTX 4080 graphics boards are still among the best graphics cards available today.

    The only way any cards are getting a price cut is if no one buys them, all cards this generation are over priced IMHO.
