If you really, really, really, need a graphics card for a low-end build, the Asus Dual Radeon RX 6400 is it. Performance is lower than the entry-level RX 6500 XT, but the good news is that the RX 6400 doesn't require extra power. However, the double-slot dual-fan design from Asus means it may not be ideal for small form factor PCs where this card would really shine.
- Dual axial cooling fans
- Up to 2,321MHz clock speed, 4GB GDDR6 video memory
- 768 Stream Processors, 64-bit memory interface
- 500W PSU needed, requires 2 slots
The RX 6400 doesn't require much power — in fact you don't even need to plug it into your PSU. The card has a power draw of 53 watts, and we're not expecting too much performance from this card. But if you're comfortable with playing games at the lowest graphical level, you may get away with it. If you're using an older machine with PCIe 3.0 slots, performance will also be lowered by around 10% or so less. The card only has a DisplayPort and HDMI 2.1 out.
We tested the Asus RX 6400 on our benchmark rig from Aftershock PC, which features a 12th-gen Intel Core i5-12600KF processor. Like the RX 6500 XT, there's only 4GB of video memory (which is low), and will impact the frame rate. Thermal performance isn't that great for a low-power card, but still tolerable at around 79 degrees Celsius at max load.
In the Borderlands 3 benchmark test on DirectX 12, Medium settings gave around 60fps, but if you want a more comfortable fps, Low will give you around 84fps. That puts its performance slightly weaker than the RX 6500 XT. In Cyberpunk 2077, Ray Tracing (RT) is unplayable. You'll have to play on the lowest settings if you want around 43fps. Even then, the game does look nice, but not as great as it could be. This is with AMD's FidelityFX Super Resolution turned on.
Retailing at S$299, the Asus Dual Radeon RX 6400 offers enough performance to get away with it. But I would only recommend this if you're planning to add a card to an older PC to play older, not as graphically intensive games. Get it from Shopee or Lazada.
