NVIDIA's GeForce RTX 4090 D GPU was launched late last year in China—this weakened variant (of the standard RTX 4090) was designed with US trade regulations in mind. Chinese media outlets have toyed around with various custom models for several months—January 2024 evaluations indicated a 5% performance disadvantage when lined up against unrestricted models. The GeForce RTX 4090 D GPU is a potent beast despite a reduced core count and restricted TDP limit, but Chinese enthusiasts have continued to struggle with the implementation of worthwhile overclocks. HKEPC—a Hong Kong-situated PC hardware review outlet—has bucked that trend.

The mega-sized flagship ZOTAC RTX 4090 D PGF model has the technical credentials to break beyond the expected overclock increase of "2 to 5%," courtesy of a powerful 28-phase power PCB design and 530 W max. TGP limit. The Expreview team pulled a paltry 3.7% extra bit of performance from ZOTAC China's behemoth. In contrast, HKEPC wrangled out some bigger numbers with a sampled ASUS ROG STRIX RTX 4090 GAMING OC graphics card—matching unrestricted variants: "it turns out that NVIDIA only does not allow AIC manufacturers to preset overclocking, but it does not restrict users from overclocking by themselves. After a high degree of overclocking adjustment, the ROG Strix RTX 4090 D actually has a way to achieve the performance level of the RTX 4090 FE."

An MSI "Ruan Mei" special edition GeForce RTX 4090 SUPRIM X model has been teased by hongxing2020 on social media—it is not clear whether this is an intentional leak, given the formal office setting photographed in the background. Seemingly finalized retail packaging, heavily updated shroud plus backplate designs, and bundled poster and mousepad merchandise are emblazoned with a 5-star rated Honkai: Star Rail character. As noted by VideoCardz, the web link displayed on MSI's accompanying poster would indicate that the special green and gold special SUPRIM X model is destined for the Chinese PC hardware market—where miHoYo's Honkai games franchise is super popular.

The MSI GeForce RTX 4090 SUPRIM X "Ruan Mei" special edition's packaging does not make a distinction between the onboard GPU being a US sanction-compliant NVIDIA GeForce RTX 4090 D variant, or the original + uncompromised AD102-300-A1. Perhaps it is safe to assume that a first quarter 2024 launch model will sport ever so slightly downgraded internals—MSI has already prepared their standard silver range-topping GeForce RTX 4090 D SUPRIM X model for the region. A small batch of Ruan Mei limited editions could arrive at a later date, once the the standard card has cleared the way.

NVIDIA has released the latest version of its GeForce graphics drivers, the GeForce 546.34 WHQL Game Ready drivers. The GeForce 546.34 WHQL Game Ready drivers bring the same game optimizations and fixes that were previously introduced with GeForce 546.33 WHQL drivers release, which include optimizations and support for DLSS 3 in THE FINALS and Squad games, as well as support for DLSS Super Resolution in Fortnite Chapter 5. The only new thing with this release is the support for the newly announced NVIDIA GeForce RTX 4090D graphics card released in China.

The list of fixes include muted colors when streaming gameplay with Discord and multiplication of the NVIDIA system tray icon whenever user is switched in Windows.

Update: The GeForce 546.34 WHQL Game Ready drivers only support the new GeForce RTX 4090D graphics card. For other graphics cards, you can download the GeForce 546.33 WHQL Game Ready drivers.

NVIDIA is preparing to launch the GeForce RTX 4090 D, or "Dragon" edition, designed explicitly for China. Circumventing the US export rules of GPUs that could potentially be used for AI acceleration, the GeForce RTX 4090 D is reportedly cutting back on overclocking as a feature. According to BenchLife, the AD102-250 GPU used in the RTX 4090 D will be a stranger to overclocking, as the card will not support it, possibly being disabled by firmware and/or physically in the die. The information from @Zed__Wang suggests that the Dragon version will be running at 2280 MHz base frequency, higher than the 2235 MHz of AD102-300 found in the regular RTX 4090, and 2520 MHz boost, matching the regular version.

Interestingly, the RTX 4090 D for China will also feature a slightly lower Total Graphics Power (TGP) of 425 Watts, down from the 450 Watts of the regular model. With memory configuration appearing to be the same, this new China-specific model will most likely perform within a few percent of the original design. Higher base frequency probably indicates a lack of a few CUDA cores to comply with the US export regulation policy and serve the Chinese GPU market. The NVIDIA GeForce RTX 4090 D is scheduled for rollout in January 2024 in China, which is just a few weeks away.
