Despite being developed with pre-built computers in mind, the recently announced AMD Radeon RX 6400, the simplest graphics card in the RX 6000 family, should receive a custom model from ASRock, intended for PCs in the mini-ITX format. At least that’s what new certifications from the Eurasian Economic Commission (EEC) suggest, registered in January but found only this week.
RX 6400 should win ASRock Challenger version
Documentation was found by renowned leaker @KOMACHI_ENSAKA and, in addition to citing editions of the RX 6500 XT and even the old RX 560, mentions a “CLI” model of the RX 6400. This is the codename used by the brand for the Challenger family of boards, developed with a focus on bringing a more compact for Mini-ITX builds, the super compact desktops.

The RX 6500 XT already has a Challenger version, which stands out for the very thin format of a single slot, as well as for the presence of a fan optimized to deliver high thermal efficiency and accompanied by a low noise profile, which disables the fan at loads of light work. A model from the line would make even more sense for the RX 6400, which employs a scaled-down version of its big sister chip, but is surprising given that the entry-level card is intended for OEMs.
This could mean that we will see pre-assembled machines with full-bodied versions of the solution, at least in Europe and parts of Asia, where ASRock’s custom edition has been approved.
Card is an even smaller version of the 6500 XT
Announced alongside the RX 6500 XT during CES 2022, the AMD Radeon RX 6400 is today AMD’s most entry-level desktop solution and one of the first cards released with TSMC’s 6nm lithography. Like its sister, the model is equipped with a Navi 24 chip, but in a smaller configuration, with only 12 Computing Units (CUs), or 768 cores, and 12 Ray Accelerators for Ray Tracing.
This is curiously the same configuration as the Radeon 680M, the company’s new integrated GPU based on the RDNA 2 microarchitecture, present in the Ryzen 6000 processors, but with the advantage of having high-speed dedicated memory and higher consumption. It’s 4GB of GDDR6 VRAM at 16Gbps, operating on a 64-bit interface to deliver bandwidth up to 128GB/s.
As is customary with RDNA 2 chips, the clocks are quite high, reaching 2,321 MHz, which allows the RX 6400 to deliver up to 3.57 TFLOPs of computing power. The entry-level solution is slated to power pre-assembled desktops from specialty retailers worldwide starting in March.
