AMD board partner XFX has with the “AMD BC-160” a new graphics card for calculating cryptocurrency, which is based on the previously exclusive Navi-12 GPU.
The Navi-12 graphics processor of the XFX BC-160 was previously only available in Apple’s MacBook Pro in the form of the AMD Radeon Pro 5600M or Radeon Pro V560, while the chip was not used in gaming and has now been used for around a year and a half after its market launch Mining purposes.
The BC-160 (abbreviation for “Blockchain Compute”) is intended for calculating Ethereum and Co. dispenses with display connections according to its area of application and has a blower cooler, while the Navi-12 GPU manufactured in TSMC’s N7 process 2,304 stream processors (36 compute units). Two 8-pin connectors are supposed to supply the card with 130 watts or 150 watts TGP under load, depending on the specification.
Furthermore, two stacks of 4 GiB HBM2 memories each are used, which are connected to a 1024-bit memory interface. The memory itself is clocked at 1.6 Gbps, which corresponds to a bandwidth of 512 GB / s. The BC-160 thus offers a hashrate of 70 MH / s (plus / minus 5 percent), which, according to videocardz.com, is mainly achieved thanks to the high bandwidth memory. Since the size of the “Ethereum DAG” file already requires more than 4 GiB of memory, according to the report, XFX could not fall back on a single 4 GiB stack. The hash rate achieved is higher than that of the Radeon RX 6800 XT or 6900 XT, which are both around 64 MH / s.
The new mining graphics card BC-160, meanwhile, is for sale on the Chinese trading platform Aliexpress a proud price of 2,158.53 euros including shipping and VAT listed. That is over 600 euros more than AMD’s top gaming model in the form of the Radeon RX 6900 XT, which is currently listed in the price comparison at best from around 1,500 euros.
