AMD has finally launched the RX 6400 in a very subtle manner. The 6400 is so far AMD’s slowest discrete GPU to date which is based on the RDNA2 architecture. This isn’t really a brand-new model; it was already announced at the start of the year for OEMs. But it has now finally been launched for the DIY market as well. The other good news is that the embargo placed on various custom designs has also been lifted. Most of these custom designs were single-fan or low-profile solutions.
Featuring the Navi 24 GPU with 768 Stream Processors, the AMD Radeon RX 6400 is a rather mellowed down version of the RX 6500 XT. The graphics card comes with a base clock of 1923 MHz, a game clock of 2039 MHz, and a boost of 2321 MHz. The clock speeds remain the same as the one which was released for the OEMs in January. Additionally, the 4 GB GDDR6X memory is spread across a 64-bit memory bus.
So far, we don’t see any factory overclocked solution from the board partners which means it is likely that these are the maximum clock speeds the card will come at.
The cards launched today don’t require any external power connector; they are all powered with the PCI-Express interface. This is sufficient to deliver the required power of 53W.
