If you are looking for a highly energy-efficient small form factor graphics card that also offers good performance then Radeon RX 6400 is one of the best options in the market right now. The card sits at the bottom of the Radeon 6000 graphics card series, just below the RX 6500 XT. RX 6400 is a card that will not be the choice of hardcore games but it will cater to the needs of casual gamers and those who want to enjoy a decent medium-level 1080p gaming on their small-form-factor systems. The major competitor of RX 6400 is the GeForce GTX 1650 from Nvidia, which is also a very good budget-level graphics card for mid-level 1080p gaming. When it comes to performance then RX 6400 performs similar to GTX 1650 and can take the performance lead in some games. In AMD only, the card that matches RX 6400 in performance is the Radeon RX 570, which is quite an older card but still capable of running the latest games at satisfactory graphics settings with playable frame rates.

After RX 6500 XT, Radeon RX 6400 is the second graphics card in the world built on the smaller 6nm fabrication process. It uses the same Navi 24 GPU chip but in a cut-down form and comes with 768 Stream Processors compared to the 1024 present in the RX 6500 XT. The RX 6400 uses RDNA 2 GPU architecture and has got 4GB GDDR6 memory having a 64-bit interface. The video memory runs at a speed of 16 Gbps and generates a memory bandwidth of 128 GB/s. The card supports PCIe 4.0 interface but the PCIe lanes are limited to x4 only. This is the main letdown of this card because even if you have a PCIe 3.0 motherboard then also RX 6400 will run at PCIe 3.0 x4 only which can lead to performance loss in some games, especially the latest ones that require larger memory bandwidth and capacity. The card supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan graphics APIs but does lack hardware encoding that includes 4K H264 Encode, H265/HEVC Encode, and even AV1 Decode is not supported. HDMI 2.1 is supported but RX 6400 cards come only with two display outputs. The power consumption of the card is on the lower side at 53W only and the card draws all of the required power from the PCI-Express x16 slot only. There are various small form factors models available from different AIB manufacturers and here I am going to list the best RX 6400 cards based on different parameters and requirements of the users.

Coolest Dual Fan RX 6400

Gigabyte Radeon RX 6400 EAGLE 4G

[Runs Cool & Quiet, Semi-passive Cooling, Compact Size]

Gigabyte Radeon RX 6400 EAGLE 4G is one of the coolest running RX 6400 cards that offer great thermal performance. Even though RX 6400 is a power-efficient GPU, the Gigabyte Radeon RX 6400 EAGLE 4G takes this one step forward by offering a very good cooling solution to cool down RX 6400 GPU. The WINDFORCE 2X cooling system on the card uses an aluminum heatsink with two copper heatpipes, a copper base plate, and dual alternate spinning fans. The fans feature a unique blade design having a triangular fan edge and 3D stripe curve for smoother and focused airflow. The fans spin in opposite directions to each other so that the airflow direction between the two fans is the same. This helps in reducing the turbulence and enhancing the airflow pressure. Moreover, the 3D Active Fan feature provides semi-passive cooling, and the fans will remain off when the GPU load is low. The card is quite silent and runs pretty quiet even when the GPU load is at maximum level.

Even with a dual-fan and dual-slot design, the card is pretty compact and is only 192mm in length. The card does not require additional power from the PSU via PCI-E power connectors. Using Gigabyte’s AORUS ENGINE software, you can adjust the graphics card clock speed, voltage, fan performance, and power target in real-time according to your game’s requirements. Display connectivity options include DisplayPort 1.4 and HDMI 2.1 ports.

Best Small Form Factor RX 6400

PowerColor AMD Radeon RX 6400 ITX

[Compact Design, Semi-passive Cooling]

PowerColor AMD Radeon RX 6400 ITX is one of the best compact RX 6400 cards for small form factor and mini-ITX systems. The card is only 165mm in length and has got dual-slot design. The card is cooled by an aluminum heatsink and a 90mm fan. The fan uses dual ball bearings for a longer lifespan and is quite silent in operation. Moreover, the Mute Fan semi-passive cooling technology stops the fan from spinning during low GPU temperatures and ensures 0db super silent operation. When the GPU temperature crosses 60°C, the fan starts automatically to keep the card cool. The card is very power efficient with a power consumption figure of 53W only. No PCI-E power connectors are required and the card draws all of its power from the PCIe x16 slot only. Display connectivity options include DisplayPort 1.4 and HDMI 2.1 ports.

Best Low-profile RX 6400

Gigabyte Radeon RX 6400 D6 LOW PROFILE 4G

[Dual-fan cooler, Runs cooler than other RX 6400 low-profile models]

The only low-profile RX 6400 card with a dual-fan cooling system. The card is 182mm in length and has got dual-slot design. The card is cooled by Gigabyte’s custom-designed low-profile cooler that comprises a low-profile aluminum heatsink and dual fans. Because of dual fans Gigabyte Radeon RX 6400 D6 LOW PROFILE 4G runs significantly cooler than other low-profile RX 6400 models. However, it can generate extra noise compared to single fan low-profile models. The card draws power from the PCIe x16 slot only and does not require supplementary power connectors from the PSU. For display output, the comes with DisplayPort 1.4 and HDMI 2.1 ports.
