AMD didn't bother with crafting reference cooler designs for its respun Radeon RX 500-series graphics cards, but that's not stopping Biostar from slapping the RX 480 cooler onto 500-series silicon. The motherboard and graphics card manufacturer has five different models based on AMD's Radeon RX 580, RX 570, and RX 550.
The only all-new models in Biostar's lineup are the RX 550 models, available with 2 GB or 4 GB of 7 GT/s GDDR5 memory. The GPUs in these cards have the usual RX 550 stable of 512 stream processors and a 128-bit wide memory bus. Biostar touts the cards' use of 100% solid capacitors and ability to comfortably run on PCIe slot power alone. The card wears a tidy single-axial-fan custom cooler and comes with a DisplayPort, an HDMI output, and a DVI connector.
Moving up the product ladder nets a pair of Radeon RX 570 options, both using 7 GT/s GDDR5 memory. The model packing the entry-level memory loadout of 4 GB comes dressed in an open-air assault-rifle-themed "FPS Cooling" apparatus with a pair of fans. Meanwhile, buyers who want an RX 570 with 8 GB of VRAM will get a card wearing something that looks a lot like AMD's reference cooler for the Radeon RX 480 and RX 470. Both cards have GPU cores with 1168 MHz base and 1244 MHz boost clocks for their 2048 SPs. They also use a single six-pin PCIe power connector. Display output comes by way of a port cluster with an HDMI port, three DisplayPorts, and a DVI output.
Biostar's sole Radeon RX 580 card comes decked out with 8 GB of 8 GT/s memory and a reference-style cooler. The full complement of 2304 SPs run at 1257 MHz when not boosting to 1340 MHz. Buyers will need to have a power supply with a free eight-pin PCIe power connector. This take on the Radeon RX 580 has the same port cluster as the RX 570s mentioned above.
Biostar didn't say when the cards would hit store shelves, but it did provide suggested pricing for them. The Radeon RX 550 should run about $80 with 2 GB of memory or $100 when decked out with 4 GB. The Radeon RX 570 with 4 GB of memory and a custom cooler will set buyers back $180, while the blower cooler-equipped 8 GB version will ring in at a more substantial $220. The top-of-the-line Radeon RX 580 is expected to fetch $250.
Perhaps the most interesting bit about this announcement is the return of Biostar as an AMD graphics card vendor. Judging by a look at the company's current and discontinued products, the last time Biostar offered a card with a graphics chip from the red team was back in the days of 2010's Radeon HD 6000 series.
