A mysterious variant of AMD's Radeon RX 570 has appeared in at the Saraba1st (via HXL ) forums. The graphics card appears to feature two Ellesmere GPUs, which effectively doubles its mining performance.

The dual-slot graphics appears to hail from Sapphire's camp as evidenced by the small logo under the shroud. According to the GPU-Z screenshot, PC Partner is the OEM who manufactured the graphics card. The model name is unknown so the graphics card has been unofficially baptized as the Radeon RX 570 Duo for now.

GPU-Z only detected a single Ellesmere GPU on the Radeon RX 570 Duo. However, the photograph of the graphics card's backside clearly confirm the presence of two GPUs.

While a single Radeon RX 570 8GB offers a mining performance in the range of 28 MH/s before optimization, the Radeon RX 570 Duo reportedly hits a hash rate of 59.72 MH/s at 125W. Software-based tools aren't the best indicators for power usage so take that number with a grain of salt.
