Indeed, the headline is accurate. An NVIDIA GeForce RTX 5090D "China" edition GPU, not the standard RTX 5090, was able to achieve a clock speed of 3.4 GHz under liquid nitrogen cooling. With a default TDP of 575 W, Tony Yu, the general manager of ASUS China, made physical alterations to enable the card to operate at a TDP of up to 1000 W. The RTX 5090D is an exclusive variant for China that is nearly identical to the regular RTX 5090, with the only difference being limited general AI capabilities due to US export restrictions. ASUS China utilized their high-end Astral OC variant for this feat, which, as demonstrated in our review of the standard ASUS RTX 5090 Astral OC, features excellent chip binning that allows for significant overclocking. We were able to push the standard RTX 5090 Astral OC GPU to 3086 MHz on air cooling, a +277 MHz increase over the stock boost setting. However, the LN2-cooled RTX 5090D equivalent managed to reach 3,390 MHz under peak loads, a difference of +581 MHz.
Impressively, the memory overclock reached 34 Gbps. In terms of performance, the LN2-overclocked RTX 5090D outperformed stock performance by around 16%. In benchmark tests, the GPU surpassed multiple graphics cards from previous generations, including a dual RTX 3090 Ti setup in Port Royal and a quad GTX 1080 Ti configuration in Fire Strike. Power consumption data indicates that a total of 1,760 W was utilized for a system featuring the ASUS ROG Astral RTX 5090D paired with the Ryzen 7 9800X3D on the ASUS ROG X870E Hero motherboard. This translates to approximately 1,000 W of power consumption by the GPU, which underwent physical modifications to handle such high power output.
