  • Built on 6nm process for efficient performance

Compact ITX graphics card for small-form-factor

The ASRock Radeon RX 6400 Challenger ITX is a low-profile graphics card built on AMD RDNA 2 architecture. It carries 4 GB of GDDR6 memory and targets compact systems that need discrete graphics for 1080p gaming or multimedia work.

Check PCIe slot version

The card uses a PCI Express 4.0 interface and will run at reduced bandwidth on older 3.0 slots. Verify that your power supply includes the required 6-pin PCIe connector and that your case can accommodate a dual-slot bracket despite the ITX-length PCB.

Single-fan cooler with zero-RPM idle mode

A single axial fan spins only when the GPU temperature rises, staying completely off during light loads for silent operation. The metal backplate stiffens the short PCB and protects the rear components during handling and installation.
