MSI introduced the first Crypto Mining Processor (CMP) called 50HX – the fastest accelerator card in the CMP series to date, before 90HX models appear. With MSI’s product page, the specific specifications are now known, including the graphics chip used.
Nvidia provides TU102 GPUs from the Turing generation for the CMP 50HX, which are not sufficient for a GeForce RTX 2080 Ti or Titan RTX, for example because of too many defects in the exposure process. The CMP 50HX uses 56 shader multiprocessors with 3584 shader cores – 22 percent less than the Titan RTX (4608 shaders) and 18 percent less than the GeForce RTX 2080 Ti (4352 shaders).
10 GByte memory
In addition, Nvidia switches off another 32-bit memory controller, so that 50HX cards get 10 GB of GDDR6 RAM. With 14 Gbps memory on 320 data paths, the transfer rate is 560 Gbytes / s. That should be enough for a mining performance in the crypto currency Ethereum of 45 megahashes per second.
The GPU clock frequency plays a subordinate role in Ethereum mining, with a boost of 1545 MHz it is even set quite high. With optimizations, the power consumption of 225 watts could presumably be further reduced.
Meanwhile, the CMP 50HX is not suitable for gamers. Like all CMP cards, it appears without image outputs, so it is only suitable as a GPU accelerator. In addition, Nvidia limits the PCI Express interface via driver and / or BIOS to four 1.0 lanes. What would cost a lot of fps in 3D games is irrelevant for miners: The Ethereum DAG (directed acyclic graph) is completely loaded into the graphics memory, so that GPUs do not have to fetch any data from the main memory.
