Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure.
A 2-slot Design maximizes compatibility and cooling efficiency for superior performance in small chassis.
Dual ball fan bearings can last up to twice as long as sleeve bearing designs.
Auto-Extreme Technology uses automation to enhance reliability.
A protective backplate prevents PCB flex and trace damage.
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 maximizing 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: Better, faster, stronger
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: Quiet intelligence
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: 2x longer lifespan
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: Sink your heat into this
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 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: That's so metal!
The PCB is reinforced by an aluminum backplate that adds structural rigidity, helping to prevent flex and protect components and trace pathways from damage.
Stainless Steel Bracket: Steel yourself
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: “Extensive” may be an understatement
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: A bit lit
The shroud features a subtle illuminated strip that creates a stylish accent for your build.
AMD Radeon Software: Change the way you game
The latest Radeon Software unleashes the full potential of your GPU with day-0 drivers optimized for new game releases and a highly customizable gaming experience.
