NVIDIA starts shipping GeForce RTX 4090 based on updated GPU

In January, NVIDIA began shipping the GeForce RTX 4080 based on an updated GPU with a built-in voltage comparator, which until then was a separate element on the graphics card circuit board. Bringing this element to the GPU should slightly reduce the cost of graphics cards. NVIDIA has now started shipping the reference GeForce RTX 4090, based on an updated GPU with a similar feature.

The information was shared by one of the Reddit forum users. Checking the graphics card in GPU-Z utility showed that the updated version has a different model number. The unique device PCI ID of the graphics card remained the same, but the Sub Device ID, which indicates the accelerator series, has changed. This fact excludes the possibility of using the original BIOS firmware for cards with the GPU AD102-300, with which the GeForce RTX 4090 model originally went on sale, on the updated model.

Dismantling the graphics card confirmed the initial assumptions. It turns out that instead of the AD102-300, an updated AD102-301 GPU is used. Curiously, no leaks have indicated that NVIDIA is planning to release a version of the AD102-301 GPU.


The user also claims that the updated AD102-301 GPU operates at a lower voltage of 1.07V instead of the original 1.1V that was advertised for the AD102-300. At the moment this information cannot be confirmed as additional graphics cards are required for verification. It is still unknown whether the reduction in operating voltage had an impact on the performance of the graphics card. Additionally, it’s not clear if these limitations only affect the Founders Edition model or if a similar voltage reduction will occur in custom versions of the GeForce RTX 4090.

The change in the maximum operating voltage of the updated GPU has been confirmed by the MSI Afterburner and ASUS GPU Tweak utilities.
