ASUS Dual Radeon RX 6400 4GB GDDR6 with two powerful Axial-tech fans and a 2-slot design for broad compatibility 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. Cooling 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. Engineering 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. Experience 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. Software AMD Radeon Software 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.
