At the Chinese forum Saraba1st published Photos of Sapphire’s Radeon RX 570 graphics card equipped with two Polaris 20XL GPUs (codenamed Ellesmere) at the same time. Each GPU contains 2048 stream processors, and the graphics accelerator itself is equipped with 16 GB of GDDR5 video memory. The novelty, apparently, is intended for mining.
The video card is only partially recognized by the GPU-Z program, which confirms that this instance is indeed a variation of the Radeon RX 570. One of the published images also demonstrates the performance of the video card in mining cryptocurrency (presumably Ethereum) and its power consumption.
According to the screenshot, GPU1 and GPU2 each draw 78W of power for a total of 156W. However, taking into account the history with the Radeon RX 6600 XT, this information probably indicates the so-called ASIC power, and the overall power consumption of the graphics accelerator may be 20-40 W higher.
The efficiency of the dual-processor Radeon RX 570 in mining is approaching 60 MH / s. The number is not very impressive, but it is comparable to the efficiency level of the uniprocessor Radeon RX 6600 XT, which, after optimization, provides 32 MH / s with a consumption of 75-78 watts.
It is not immediately clear that the card on the photo was developed by Sapphire. There are no identification marks on the graphics accelerator that would indicate the manufacturer. However, the company logo was found on one of the power supply subsystem (VRM) chokes located under the heatsink.
The miner’s purpose of the card is indicated by a lone external HDMI connector. The limitation in the number of video interfaces or their complete absence usually means that the card is designed for use in crypto farms.
