A mysterious variant of AMD Radeon RX 570 Has appeared in Salaba first (Via Twitter user Oversized) Forum. The graphics card seems to be equipped with two Ellesmere GPUs, which effectively doubles its mining performance. Not sure if this is AMD’s new product or just a partner with creative design.
The dual-slot graphics seems to come from Sapphire’s camp, as the small logo under the shield proves this. According to the GPU-Z screenshot, PC Partner is an OEM that manufactures graphics cards. The model name is unknown, so the graphics card has been unofficially named Radeon RX 570 Duo for the time being.
Interestingly, GPU-Z has no problems when detecting Radeon RX 570 Duo. However, the software only detected a single Ellesmere GPU on the Radeon RX 570 Duo. However, the picture of the graphics card PCB clearly confirms the existence of the two GPUs. Radeon RX 570 Duo uses 1,120 MHz base clock and 1,150 MHz boost clock for inspection. In contrast, the clock speed is even lower than the original Radeon RX 570, but this is normal for mining graphics cards. Sapphire may keep the clock speed as low as possible to optimize power consumption.
So where did all the power budget go? Of course it is for memory. Radeon RX 570 Duo is equipped with 16GB of GDDR5 memory in an 8+8 configuration. The memory interface remains unlinked at 256 bits. According to the GPU-Z screenshot, the memory clock frequency is 2,100 MHz (8.4 Gbps effective). Radeon RX 570 memory is checked at 1750 MHz (7 Gbps valid), so the memory overclocking of Radeon RX 570 Duo has increased by 20%.
A single Radeon RX 570 8GB provides mining performance in the range of 28 MH/s before optimization. On the other hand, according to reports, the hash rate of Radeon RX 570 Duo reached 59.72 MH/s. This makes sense because there are two Ellesmere molds on board. The 60 MH/s computing power basically combines the aging AMD graphics card with GeForce RTX 3060 Ti Before Ampere mining weakened.
The screenshot claims that the Radeon RX 570 Duo has a power of 125W, which is unlikely. The original Radeon RX 570 8GB consumes 130W alone, so it is impossible for two Ellesmere GPUs to consume only 125W. Therefore, we have reservations about this power value.
The Radeon RX 570 Duo comes with a simple black shield with two cooling fans. There is even an HDMI port, so it can be used as a normal game graphics card. Each Ellesmere chip has its own heat sink and a pair of copper heat pipes for heat transfer.
The PCIe power connector is located on the back of the graphics card. Although the photo does not clearly show the connector, the PCB trace corresponds to two 8-pin PCIe power connectors, which makes us doubt the claim of 125W power consumption. For reference, the Radeon RX 570 has a power rating of 150W and relies on a single 6-pin PCIe power connector.
GlobalFoundries initially produced Ellesmere silicon for AMD at the foundry’s 14nm process node. We believe that AMD did not allow GlobalFoundries to restart the furnace, so Sapphire has some remaining inventory of Ellesmere molds, and it makes sense that the brand needs to get rid of these inventory.
A user on the Saraba1st forum stated that he paid RMB 5,300 or US$818 for the Radeon RX 570 Duo.This is a pretty high price, considering you can only pick up two Radeon RX 6600 XT And get the same mining performance.Although AMD did not design RDNA 2 for mining, the Radeon RX 6600 XT has Proved to be very effective In it. With some adjustments and patience, you can get 32 MH/s power from the Navi 23 graphics card, and the power consumption is about 75W.
