The front panel of the card features a variety of outputs, such as

Port 1.4 and HDMI 2.1. HDMI 2.1 supports up to 48 Gb/s bandwidth and a range of higher resolutions and refresh rates, including 8K @ 60 fps, 4K @ 120 fps, and even up to 10K. The Radeon RX 6400 supports APIs such as DirectX 12 Ultimate and OpenGL. These APIs can take advantage of the GPU's 768 Stream

For cooling, MSI implemented a single fan cooler.DirectX 12 UltimateDirectX12 Ultimate gives game developers the power to deliver immersive visuals with real-time DirectX Raytracing (DXR), Variable Rate Shading (VRS), Mesh Shaders, and Sampler Feedback, taking games to the next level.AMD FidelityFXAMD FidelityFX is an open-source image-quality toolkit comprising of seven different solutions available for game developers to implement into their games that are optimized for AMD RDNA and RDNA 2 architectures.AMD Radeon Image SharpeningRestores clarity to in-game images that have been softened by other post-process effects. RIS combines with GPU upscaling to provide sharp visuals at fluid frame rates on very high-resolution displays, and works across DirectX 9, 12, and Vulkan titles.AMD FreeSync TechnologyReduce screen tearing with AMD's FreeSync Technology. FreeSync enables the monitor to dynamically adjust its refresh rate to the frame rate being output by the graphics card, thereby greatly reducing screen tearing, stuttering, and other artifacts.Radeon Anti-LagOptimized for esports, Radeon Anti-Lag improves competitiveness by decreasing input-to-display response times by up to 31 percent, delivering an experience similar to higher frame rates.
