It looks like the AMD Radeon RX 500 series SKUs, such as the RX 580, RX 570, and RX 550, will become available later this month. According to the latest rumor from Videocardz, a few popular online stores listed various models from ASUS and Sapphire. While at the moment these cards are overpriced due the pre-launch orders, they should be just re-brands of the RX 480, RX 470, and RX 460, with slightly higher reference clock speeds and improved efficiency and therefore the price will drop already at launch.


ASUS is going to have a least six different SKUs ready. including two RX 580 8 GB STRIX models, two RX 570 4 GB STRIX cards and two RX 550 SKUs with 4 GB and/or 2 GB of VRAM. Sapphire, on the other hand, appears to be preparing 12 SKUs, which are going to be based on the three different chips as well. There will be RX 580 and RX 570 cards with 8 GB and 4 GB of VRAM, as well as RX 550 cards with 4 GB and 2 GB memory. According to Videocardz Sapphire will add two new series which go by the name Pulse and the Mini.
