ASRock Prepares Radeon RX 6400 Challenger ITX Graphics Card, No Power Connector Required
ASRock Introduces Radeon RX 6400 Challenger ITX Model
Like it or not, custom Radeon RX 6400 graphics cards are coming.
ASRock is preparing a new model designed in an ITX form factor. Following the launch of Radeon RX 6500XT, AMD’s first graphics card with Navi 24 6nm GPU, the card partners are now preparing to unveil their RX 6400 models as well. These cards will feature custom cooling solutions.
The RX 6400 board pictured below is part of the Challenger ITX series. Although it is a relatively small card, it is still a dual slot design, just like the 6500XT model.

One can immediately notice that the coolers are not the same, in fact even the fin array behind the fan has been replaced with an aluminum heatsink and the fan itself is also smaller. The most significant change however is visible to the naked eye, the 8-pin power connector is missing. This is because the RX 6400 has lower card power than the 6500XT (53W versus 107W).

The RX 6400 graphics card has 768 stream processors and 4 GB of GDDR6 memory on a 64-bit interface. As stated earlier, Navi 24 is a power-efficient GPU, but it was not designed for gaming. The RX 6500XT was already named “the worst GPU” in the RDNA2 series due to limited bandwidth, lack of encoding capabilities and requirement for a PCIe Gen4 x4 interface, as it is noticeably slower on Gen3. With even fewer cores activated, the RX 6400 will be a sell-out for anything other than integrated GPU replacement or home theater systems.
AMD is expected to launch the Radeon RX 6400 for the DIY market on April 20. The board is already available from OEMs and system integrators.
