Radeon RX 570 Revival: Dual-GPU Mining Beast Hits 60 MH/s

A mysterious variant of AMD's Radeon RX 570 has appeared over at the Saraba1st (via Twitter user HXL) forums. The graphics card appears to feature two Ellesmere GPUs on a single PCB, effectively doubling its mining performance. It's uncertain if this is a new AMD product or just an AIB partner that got creative with the design.

The dual-slot graphics appears to hail from Sapphire's camp as evidenced by the small logo on one of the chokers hidden 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.

It's interesting that GPU-Z didn't have any problems detecting the Radeon RX 570 Duo. The software only detected a single Ellesmere GPU on the Radeon RX 570 Duo, though. However, the photograph of the graphics card's PCB clearly confirms the presence of two GPUs. The Radeon RX 570 Duo checks in with a 1,120 MHz base clock and 1,150 MHz boost clock. By comparison, the clock speeds are even lower than the original Radeon RX 570, but that's normal for a mining graphics card. Sapphire probably kept the clock speeds as low as possible to optimize power consumption.

So, where did all the power budget go? To the memory, of course. The Radeon RX 570 Duo comes equipped with 16GB of GDDR5 memory in a 8+8 configuration. The memory interface remains unchained at 256-bit. As per the GPU-Z screenshot, the memory is clocked at 2,100 MHz (8.4 Gbps effective). The Radeon RX 570's memory checks in at 1750 MHz (7 Gbps effective), so the memory overclock on the Radeon RX 570 Duo represents a 20% increase.

A single Radeon RX 570 8GB offers a mining performance in the range of 28 MH/s before optimization. The Radeon RX 570 Duo, on the other hand, reportedly hits a hash rate of 59.72 MH/s. This make sense since there are two Ellesmere dies onboard. A hash rate of 60 MH/s basically puts the aging AMD graphics card on the same level as the GeForce RTX 3060 Ti preceding the Ampere mining nerf.

The screenshot claims that the Radeon RX 570 Duo draws 125W, which is unlikely. The vanilla Radeon RX 570 8GB pulls 130W alone so there's no way two Ellesmere GPUs only sip 125W. Therefore, take that power value with a grain of salt.

The Radeon RX 570 Duo sports a simple, black shroud with two cooling fans. There's even a HDMI port so it can function as a normal gaming graphics card. Each Ellesmere die has its own heatsink with a couple of copper heat pipes for heat transfer.

The PCIe power connectors are located at the rear of the graphics card. Although the photographs don't clearly show the connectors, the PCB traces correspond to two 8-pin PCIe power connector, which puts us in doubt of the 125W power consumption claims. For reference, the Radeon RX 570 is rated for 150W and relies on a single 6-pin PCIe power connector.

GlobalFoundries originally produced the Ellesmere silicon for AMD on the foundry's 14nm process node. We don't think AMD had GlobalFoundries restart the furnace so it's plausible that Sapphire has some leftover inventory of Ellesmere dies that the brand needed to get rid of.

One user from the Saraba1st forums stated that he paid 5,300 yuan or $818 for the Radeon RX 570 Duo. That's a pretty steep price, considering that, if you hunt long enough, you can pick up two Radeon RX 6600 XT and get the same mining performance. Even though AMD didn't design RDNA 2 specifically for mining, the Radeon RX 6600 XT has proven to be very efficient at it. With some tuning and patience, you can get 32 MH/s out of the Navi 23 graphics card with a power draw around 75W.

Sapphire Radeon RX 570 Duo ‘Dual AMD Polaris’ Mining Graphics Card Pictured, Delivers 60 MH/s at 125W

Sapphire's Radeon RX 570 Duo Graphics Card With Dual AMD Polaris GPUs Pictured 1

Sapphire has released a new mining graphics card that features two Radeon RX 570 GPUs based on the AMD Polaris architecture. The graphics card is designed for mining but it also features a display output which means that the card can be used as a regular graphics card.

While AMD Polaris is a relatively old architecture by now, it still can be repurposed as a decent mining option. This particular variant looks brand new which means that Sapphire might have older Polaris GPUs still lying around in their inventory and selling them as mining graphics cards such as the one we are looking at right now.

Coming to the design, the Sapphire Radeon RX 570 Duo (not an official name) features a dual-slot design and a custom PCB solution that features two AMD Polaris 10 GPUs. The graphics card has a dual-fan cooling solution and each GPU is equipped with its own heatsink block that comprises several heat pipes. Looking at the back of the PCB, we can see traces of 8 GDDR5 memory chips so that's 16 GB of GDDR5 memory in total that runs across a 256-bit x2 bus interface.

The Radeon RX 570 is a cut-down AMD Polaris chip with 2048 cores activated out of the total 2304 cores. This variant features a GPU clock of 1150 MHz and a memory clock of 2100 MHz or 8.4 Gbps. The GPU and memory clocks are definitely optimized for maximum mining output. There are two 8-pin connectors featured on the PCB but the card only consumes 125W power and delivers a rate of 60 MH/s in Ethereum. Temperatures are also maintained at a steady 60-65C. The user reports that he was able to get hands-on the graphics card for 5300 RMB which puts the price of this card at around $850 US.

This is quite a high price for this level of performance as the RTX 3060 Ti (Non-LHR) can deliver the same performance at a much lower price point and higher efficiency. Even the recently released AMD Radeon RX 6600 XT has a higher performance per watt rating in mining than the older Polaris-based graphics card.

    Then he doesn't remember how he went to his neighborhood, how he found a house. who helped to get there. We, his parents, found the second "drinking companion" on the same night, asleep, unconscious, in that very kindergarten. The third "shot" managed to go deep into the forest in the opposite direction, get out to the bus stop, get on. The night bus, from which we "took off" it.

    Spreading her legs, she sat down pressing my penis with a wet slit. Oh, how nice it is to snuggle up to her elastic ass, she has such a silky skin of her delicate tight buttocks, and even she squeezed her legs. And my penis just burns very close to her hot pussy. That would be to stick it in the ass. But not right now.
