NVIDIA GeForce RTX 4090 Gets A Silent GPU Update, Now Ships With AD102-301 Die
NVIDIA has silently started shipping a new AD102 GPU die for its flagship GeForce RTX 4090 graphics card.
A few months ago, NVIDIA started shipping revised GPU dies for its GeForce RTX 40 GPUs that were rolling out in the retail segment. The RTX 4080 and RTX 4070 Ti were the first to get the new chips & allowed AIBs to reroute the voltage comparator from the GPU to the board itself. This was not a big change but a necessary one for a more optimized and efficient operation of the Ada GPUs.
Redditor, cavitysearch123, has now discovered that the NVIDIA GeForce RTX 4090 graphics cards are also shipping with a new die known as the AD102-301 GPU.
Not only is the GPU been changed but the board number has also been revised to "16F4" whereas the original Founders Edition cards were based on the "165B" board. Based on the looks of the GPU, it is essentially the same design & the only visual change that one can make is the label with the new GPU SKU ID.
The user didn't stop there and proceeded to run a few tests on the new NVIDIA GeForce RTX 4090 Founders Edition graphics card. It looks like the maximum voltage for the new GPU is limited to a max of 1.070V while the original Founders Edition offered a maximum tuning voltage of 1.1V. Also, the older FE BIOS cannot be flashed on the new card or vice versa due to the difference in the IDs.
To confirm that the voltage was indeed lower, MSI's Afterburner was used and you can see that the card peaks out at 1.070V. Even manually adjusting the core voltage and adjusting the frequency & voltage curve didn't change anything for the newer NVIDIA GeForce RTX 4090 graphics card. The same was the case when using ASUS's GPU Tweak utility. Now the Ada Lovelace GPUs are highly efficient in the way they
