AMD’s Navi 22 silicon powers some of the best graphics cards on the market. Apparently, one of the chipmaker’s partners has repurposed the die for cryptocurrency mining. VideoCardz today shared photographs of an alleged Navi 22-powered mining graphics card.

In screenshots VideoCardz shared, most of the graphics card’s specifications are blurred out, but Navi 22 (aka Nashira Summit) is visible, letting us know that the card was fabricated on TSMC’s 7nm FinFET process node. The manufacturing date is March 17, so the graphics card recently came out of the oven. The XFX logo is also clearly stamped on the card. The Navi 22 device reportedly features 2,304 stream processors, pointing to either a rewarmed Radeon RX 6700 or Radeon RX 6700M.

The mining graphics card operates with a fixed 1,300 MHz base clock, which is understandable, since you don’t really need high clock speeds for mining Ethereum. It features 10GB of GDDR6 memory at 16 Gbps across a 160-bit memory interface. This is the same memory configuration as on the Radeon RX 6700M, leading us to believe that XFX probably recycled the mobile graphics card into a desktop unit.

According to the screenshot, the Navi 22 graphics card delivered at hash rate of 39.06 MHps in Ethereum. It got as hot as 92 degrees Celsius, which is to be expected for a passively cooled graphics card. For comparison, the mining graphics card’s performance is on par with the Radeon RX 5600 XT (39.6 MHps) and in the same alley as the GeForce RTX 3060 Ti LHR (42.9 MHps).
