NVIDIA’s new GeForce RTX 4090 Founders Edition with AD102-301 GPU
It has been reported by Redditor “cavityserach123” that NVIDIA is now shipping a new RTX 4090 variant under its Founder Edition series.
We learned almost two months ago that NVIDIA will be shifting its production from RTX 40 GPUs to new variants. According to the original report, the company was all set to introduce new RTX 4070 and RTX 4080 variants with updated GPUs.
As mentioned, these changes were required to enable a new voltage comparator circuit on the board, it was no longer required to use the GPU comparator for this feature. Some reports claimed that this could result in slightly cheaper boards and lower build costs for AIB and NVIDIA as a result. However, the price of RTX 40 GPUs hasn’t really changed much right now, so that’s probably not true.
Redditor “cavitysearch123” has just received the latest RTX 4090 Founder Edition after 3 months of waiting. It appears that the card you were sent was one of the first to feature the AD102-301 GPU. The interesting part is that there were no reports that the RTX 4090 would also get this ‘301’ GPU update.
Taking a closer look, the owner noticed that this RTX 4090 FE has a new model ID at GPU-Z. The PCI ID of the device is the same, but the Secondary ID has changed. This means that updating the BIOS with the AD102-300 based model should not be possible and specifically this is confirmed by the user.
The maximum power limit for this variant is claimed to be lower than the original SKU. Instead of 1.1 V, the maximum voltage is supposedly 1.07 V. If this is true, we can’t be sure because this requires more samples to verify. Also, it’s unclear if only NVIDIA Founders Edition is “affected” by this cap or if we should expect a similar voltage cap to be implemented on custom RTX 4090s as well.
The maximum voltage was confirmed via the MSI Afterburner voltage/frequency curve editors and ASUS GPU Tweak. Despite the changes, the maximum voltage remains at 1.07 V. Updating the BIOS to the ‘stock’ RTX 4090 BIOS is not possible due to a PCI ID mismatch.
Hopefully this change is not major and will not have any performance impact. Of course, we can’t wait to see one of these new AD102-301 cards get tested by independent media soon.
