AMD is planning to launch its new RX 6000 series GPU on April 20th and according to a recent tweet by the RRA bot (via Videocardz)  which monitors new releases of ICs - AMD seems to have changed its mind about not introducing any non-OEM version of the company's tiniest GPU: the RX 6400.

RRA stands for National Radio Research Agency and all-new GPUs must receive certification before they are allowed to be sold in South Korea. This means that all new GPUs will eventually, inevitably be spotted here just before release. In fact, in the past companies like AMD and NVIDIA have gotten dummy cards certified to throw off the tech press - but this card isn't exciting enough to warrant tactics like that so we are fairly sure this one is legit.
