BIOSTAR today announced its Extreme Gaming line of custom-design AMD Radeon RX 5000 series graphics cards. These are the company's first custom-design AMD Radeon products, as the company in the past only sold reference-design RX Vega-series products. The lineup currently includes two products, the VA57T6XM82, based on the Radeon RX 5700 XT, and the VA55T6XF81, based on the RX 5500 XT (4 GB). Both cards appear to use AMD reference-design PCBs paired with custom-design cooling solutions. The RX 5700 XT card uses a large triple-fan aluminium fin-stack cooling solution that's slightly thicker than 2 slots. The RX 5500 XT card uses a more compact twin-fan, double-slot cooling solution. The BIOSTAR Extreme Gaming RX 5700 XT sticks to AMD reference clock speeds of 1755 MHz boost, while the RX 5500 XT does 1717 MHz MHz. The company didn't reveal pricing.
