NVIDIA GeForce RTX 4090 D Gaming GPU For China Does Not Support Overclocking, Sips Lower Power

NVIDIA’s China-Exclusive GeForce RTX 4090 D Gaming GPU might not offer overclocking support while shipping with cut-down specifications.

NVIDIA GeForce RTX 4090 D Gaming GPU Cannot Be Overclocked According To Report

Benchlife follows up on the previous leak with two new details regarding the NVIDIA GeForce RTX 4090 D which is a Gaming GPU designed exclusively for the Chinese market. The GPU will be made to replace the original RTX 4090 which has been restricted in China due to the latest US regulations imposed on various companies. As such, the RTX 4090 D will serve as the flagship and the fastest gaming chip in the country when launched.

We have been getting bits and pieces regarding the GeForce RTX 4090 D ever since we exclusively revealed its existence to the public. Based on the new information, it looks like the card will draw slightly lower power than the GeForce RTX 4090 which is rated at 450W.

The GeForce RTX 4090 D will reportedly have a TGP of 425W which is 25W lower than the original model and it should be expected since the card features a cut-down GPU known as the AD102-250 which should feature a lower number of cores to meet fall within the allowed TPP (Total Processing Performance) parameters.

The major detail that has been pointed out by Benchlife is that the NVIDIA GeForce RTX 4090 D GPU won’t feature overclocking support. Now that’s a particularly interesting decision since the GeForce RTX 4090 does support some good OC capabilities which allow the card to run at over 3000 MHz. The RTX 4090 D comes with very similar clocks so it shouldn’t be that hard to OC it but based on this report, it looks like OC is artificially or hardware-locked on the AD102-250 SKUs.

We can confirm that NVIDIA will not open any overclocking settings for the GeForce RTX 4090 D.

It will be interesting to see how AIBs respond to this as they always make an OC and a non-OC design centered around a flagship product. This means that all custom designs from AIBs that make an NVIDIA GeForce RTX 4090 D graphics card would have to stick to the reference clock speeds which are rated at 2280 MHz base and 2520 MHz boost clocks. From what we have been told, the RTX 4090 D is in full production at the moment with AIBs already finished with marketing so we are looking at a late January launch if everything goes according to plan.
