NVIDIA’s introduction of the RTX 4090D graphics card is shaping up to be one of the most unorthodox debuts in the industry’s history. Straying from their usual launch strategy, NVIDIA made no prior announcements on social platforms or their blog. The RTX 4090D simply materialized on NVIDIA’s website, taking the place of the original RTX 4090 SKU, which vanished as quickly as it had appeared.
Chinese manufacturers were the first to acknowledge the new model, swiftly listing it on their websites. This not only brought the full specifications to light but also indicated the breadth of the new product’s release.Nvidia
The lineup consists of fourteen models that are essentially rebranded RTX 4090 cards, with a slight decrease in core count. The RTX 4090D shines with an 11% uptick in Streaming Multiprocessors (SMs) efficiency and operates at a 2% increased base clock speed. Its thermal design is optimized, boasting a 425W Thermal Design Power (TDP)—6% less than its predecessor—which hints at a minimal performance gap between the RTX 4090 and 4090D, potentially in the single digits.
However, the real-world performance of the RTX 4090D remains speculative until NVIDIA sends out review units to tech analysts in China, an event eagerly anticipated by the tech community.

The power specifications for the NVIDIA RTX 4090D are set firmly at 425 watts across several brands, indicating a solid power limit. This specification suggests that enthusiasts looking to manually boost the card’s performance through overclocking may face some hurdles.
In the realm of factory tuning, expectations were leaning towards NVIDIA capping the RTX 4090D’s overclocking capabilities. Our analysis confirms this; none of the models examined show any factory overclocking features.
Nonetheless, a handful of these models come with a dual-BIOS functionality, allowing users to switch between ‘Gaming’ and ‘Silent’ performance modes, despite not being specifically marketed for overclocking. A standout exception is the MSI SUPRIM X version of the RTX 4090D. It boasts a boost clock of 2535 MHz, which is slightly above the NVIDIA reference specification. However, this higher clock speed isn’t set by default and needs to be enabled via software, indicating that it’s more of an optional overclocking feature rather than a standard setting.

The NVIDIA RTX 4090D graphics card is now up for pre-order in China, the primary market for its launch. Despite ZOTAC listing two variants for purchase, they are not expected to remain in stock for long. Rumblings in the tech community suggest a wider release by late January, with Vietnam among the countries likely to receive the card due to specific import restrictions.
The RTX 4090D is tagged with an initial price point of 12,999 RMB, mirroring the launch price of its predecessor, the original 4090. However, ZOTAC has taken the initiative to set a higher price for their RTX4090D Trinity at 13,999 RMB and 16,999 RMB for the RTX 4090D PGF edition, indicating a premium for their flagship offerings. These pricing details have been sourced from IT Home’s latest reports.
