2x Fans, 2x Fun
Featuring the latest AMD RDNA™ 2 architecture, ASUS Dual Radeon™ RX 6400 fuses dynamic thermal performance with broad compatibility. Advanced cooling solutions from flagship graphics cards — including two Axial-tech fans for maximising airflow to the heatsink — are packed into the 20 cm long, 2-slot card, delivering more power in less space. These enhancements make ASUS Dual the perfect choice for gamers who want heavyweight graphics performance in a compact build.
Axial-Tech Fan Design
Two tried-and-true Axial-tech fans feature a smaller hub that facilitates longer blades and a barrier ring to increase downward air pressure.
0dB Technology
To eliminate unnecessary noise, a stop mode halts all fans when the GPU temp falls below 52 degrees and power consumption is low.
Dual Ball Fan Bearings
Different bearing types have unique pros and cons. Ball bearings excel at durability and can last up to twice as long as sleeve bearing designs.
2-Slot Design
A carefully designed shroud, heatsink, and heatpipe layout allows the two Axial-tech fans to leverage chassis side-panel ventilation and deliver thermal performance that belies the card’s size.
Auto-Extreme Technology
Auto-Extreme Technology is an automated manufacturing process that sets new standards in the industry by allowing all soldering to be completed in a single pass. This reduces thermal strain on components and avoids the use of harsh cleaning chemicals, resulting in less environmental impact, lower manufacturing power consumption, and a more reliable product overall.
Protective Backplate
The PCB is reinforced by an aluminium backplate that adds structural rigidity, helping to prevent flex and protect components and trace pathways from damage.
Stainless Steel Bracket
The mounting bracket of the Dual has been beefed up with 304 Stainless Steel that is harder and more resistant to corrosion.
144-Hour Validation Program
Each card must meet rigorous performance and reliability standards before it ships. Performance and stress tests are run with the latest chart-topping titles like Fortnite, League of Legends, Overwatch, and PlayerUnknown's Battlegrounds. We also carry out reliability trials that include a 144-hour stability test and a series of 3DMark benchmarking runs to ensure the card performs well when pushed to the limits.
Subtle Lighting
The shroud features a subtle illuminated strip that creates a stylish accent for your build.
AMD Radeon™ Software
The latest Radeon™ Software unleashes the full potential of your GPU with day-0 drivers optimised for new game releases and a highly customisable gaming experience.
