At the disposal of the portal VideoCardz there was information about the mysterious graphics accelerator AMD BC-160 manufactured by XFX. According to the source, this video card is intended for mining and is based on the Navi 12 GPU. Note that AMD released only one video card on this GPU – the mobile Radeon Pro 5600M for last year’s Apple MacBook Pros.
The Radeon Pro 5600M graphics card is powered by a 2560 stream processor chip and has dual HBM2 memory chips with a bandwidth of 1.54 Gbps. According to the source of the leak, the AMD BC-160 graphics card is based on a stripped-down version of the Navi 12 GPU with 2304 stream processors and is equipped with 8 GB of HBM2 video memory. However, at the same time, it is indicated that the memory bandwidth is 4 Gb / s. This memory standard does not have such a bandwidth, but it does the HBM2E memory, submitted by by Rambus back in September last year. It is very likely that in the case of AMD BC-160 is an error in the specification description.
Confirm or deny the existence of a mining accelerator AMD BC-160 through its own channels among manufacturers of computer equipment to the portal VideoCardz failed. The source of the leak, in turn, also provided several photos of the graphics accelerator as part of the mining farm.
The video card itself is equipped with a passive cooling system, two 8-pin connectors for additional power and has a declared power consumption level of 150 watts. The performance of the accelerator in mining is 69.5 MH / s, which is 25% more than, for example, the Radeon RX 5700 XT model based on GPU Navi 10. One of the photos shows that with the Ethash algorithm the card demonstrates performance at the level 72 Mhesh / s.
