Nvidia has quietly started using a new version of its AD102 graphics processing unit for its GeForce RTX 4090 Founders Edition graphics cards. reddit Post (via video cards). The new version is marked as AD102-301 and although the information is unofficial, it is believed to have a minor impact on the graphics board bill of materials cost.
“I received one of the new batches [GeForce RTX 4090] We inspected the Founders Edition card and found it to be the new production GPU die AD102-301-A1,” writes cavitysearch123. Reddit post.[The] The board also has a new designation 16F4. No news about this. [GeForce RTX] 4080 series new arrival [AD103-301] revision. “
One of the reasons Reddit users started researching which GPU version and revision they are using is that the AD102-301’s maximum voltage is limited to 1.070V, while the AD102-300 supports a maximum voltage of Because it is 1.1V. From a normal user’s point of view, this difference doesn’t seem to matter, but from an overclocking point of view, it does. Still, the user was able to push his GPU up to his 3 GHz with liquid cooling. This makes his GeForce RTX 4090, the best graphics card available today, even faster.
“It can stabilize 3015MHz at 1.070V, but more headroom is always welcome to ensure stability,” said the user. “I don’t know if it’s stock configuration, but this is under the water block. I think the performance is even worse.” [with stock cooling] as the temperature rises. ”
The printed circuit board for this AD102-301 based GeForce RTX 4090 FE card has a different ID than the PCB for the RTX 4090 FE product with AD102-300, so you can flash it with the original firmware with higher maximum voltage. You can not. .
Earlier this year, Nvidia quietly started using their AD103-301 and AD104-251 chips in their graphics processors for their GeForce RTX 4080 and GeForce RTX 4070 add-in boards, respectively. As reported, these GPUs have built-in comparators that ensure the fans are spinning at the proper speed by comparing the fan’s PWM signal to the actual value. In previous configurations (AD103-300 and AD104-250), the comparator circuit was disabled, so the manufacturer of the actual graphics card had to add a comparator circuit to the card.
The difference between AD102-300 and AD102-301 is unknown, but if AD102-301 integrates the aforementioned circuits, it will affect the BOM cost of GeForce RTX 4090. Nvidia’s GeForce RTX 4090 Founders Edition, on the other hand, starts at $1,599, so a slightly lower BOM will have little effect on the retail price. Still, if the changes between the AD102-300 and AD102-301 weren’t a working comparison, but something else, we can only speculate how this would affect the performance or cost of his GeForce RTX 4090 board. you can’t.
