AMD Radeon board partners BIOSTAR and XFX today released their custom-design RX 6400 graphics cards, in what could be a sign that board partners are allowed to quietly release the entry-level GPU. The BIOSTAR Radeon RX 6400 Gaming is a full-height graphics card with a simple aluminium mono-block fan-heatsink, and a lack of any additional power connectors. The XFX Radeon RX 6400 SWFT 105, on the other hand, is a low-profile, single-slot graphics card that may find appeal among the SFF crowd. It appears to be using an aluminium channel-type cooler with a 40-50 mm blower. The RX 6400 is carved out from the 6 nm "Navi 23" silicon by enabling 12 out of 16 RDNA2 compute units (768 stream processors), and comes with 4 GB of GDDR6 memory across the chip's 64-bit wide memory interface. We're hearing that at reference specs, the RX 6400 has a typical graphics power (TGP) of just 53 W, which is how it's able to make do without any power connectors.
