The mythical Navi 12 based mining GPU from AMD has surfaced. The pictures shared by Videocardz show a robust design from XFX aimed at the Chinese market. It features the Navi 12 die (RDNA 1.x), the same as the Radeon Pro 5600M powering the MacBook Pro with 8GB of HBM2 memory. The Navi 12 core has been cut down from 2,560 to 2,304 shaders, with the high-bandwidth memory delivering the necessary bandwidth for potent mining performance.
As per the leaked slide, the HBM2 memory is clocked at 4 Gbps and the bus width is a massive 2048-bit split into two 1024-bit channels. The GPU itself is fabbed on TSMC’s N7 node, and (surprisingly) supports the PCIe Gen 4 standard as well.
The Navi 12 mining GPU is named the AMD BC-160, BC for Blockchain Compute, 1 for 1st Gen, and 60 indicating the mining performance (hash rate). The shared screenshot confirms the Ether hash rate of 72 MH/s, making it one of the top-end mining GPUs on the market after the GeForce RTX 3080/3080Ti/3090.
The mining system features a total of x12 Navi 12 GPUs, resulting in an insane overall mining performance of 864 MH/s. Considering the backlash against miners and the recent mining ban in China, this SKU is unlikely to see the light of the day.
