NVIDIA has begun shipping a new AD102 GPU die for its flagship NVIDIA GeForce RTX 4090 graphics card quietly. As we previously reported, NVIDIA began shipping revised GPU dies for its retail-ready GeForce RTX 40 GPUs. The new chips were first introduced in the RTX 4080 and RTX 4070 Ti, allowing AIBs to reroute the voltage comparator from the GPU to the board itself. This was a minor change that was required for the Ada GPUs to operate more efficiently and effectively.
The NVIDIA GeForce RTX 4090 graphics cards are now shipping with a new die known as the AD102-301 GPU, according to Redditor cavitysearch123.
The GPU has been replaced, but the board number has also been changed to “16F4”, whereas the original Founders Edition cards were based on the “165B” board. Based on the appearance of the GPU, it is essentially the same design, with the only visual difference being the label with the new GPU SKU ID.
The user did not stop there, instead running a few tests on the new NVIDIA GeForce RTX 4090 Founders Edition graphics card. The new GPU appears to have a maximum voltage of 1.070V, whereas the original Founders Edition had a maximum tuning voltage of 1.1V. Due to the difference in the IDs, the older FE BIOS cannot be flashed on the new card or vice versa.
MSI’s Afterburner was used to confirm that the voltage was indeed lower, and the card peaks out at 1.070V. Even manually adjusting the core voltage and the frequency and voltage curve had no effect on the newer NVIDIA GeForce RTX 4090 graphics card. The same thing happened when I used ASUS’ GPU Tweak utility.
