A Vietnamese retailer is apparently selling Radeon RX 500 graphics cards as we speak and it seems that guys from Genk website already have one.
The card is based on Polaris 20 GPU clocked at 1244 MHz. This particular variant has 2048 Stream Processors, so just like RX 470. HIS RX 570 has 4GB GDDR5 memory rated at 7 GHz effective speed.
The ‘new’ card from HIS looks almost identical to HIS RX 470 IceQX2, which has a GPU clock at 1226 MHz, so we are looking at a moderate performance boost over predecessor.
By the way, those specs match our prediction from over a month ago.
