Intel Arc A380 video card was taught to mine Ethereum, but it doesn't do it very efficiently

Nanominer, a cryptocurrency mining software developer, added support for Intel Arc graphics gas pedals to its software.
This is the first such solution.
Recall that officially Intel Arc graphics cards do not support mining.Image source: Red Panda MiningAccording to VideoCardz, the new software has already been tested by cryptominers.
The latter confirmed that the Intel card has indeed learned to mine cryptocurrency - but not very effectively.
The Arc A380 is the only Arc graphics card officially available so far.
Its performance in Ethereum cryptocurrency mining is 10.2 Mhash/s without optimizations.
If we take into account that the typical power consumption of the card is 75W (confirmed by mining tests), the efficiency is very low - worse than, for example, the GeForce GTX 1660.It is explained that the Intel card in mining suffers from low memory bus size (96-bit), as well as a relatively small number of graphics cores (8 cores Xe).
Therefore, this Arc A380 provides an efficiency of 0.136 Mhash/s per watt of power consumption, below the average of 0.38 Mhash/s for most popular GPU models.
Intel Arc A380 in ETH miningThe Arc A380 can mine Ethereum (ETH) or Ethereum Classic (ETC) depending on the settings.
This is due to the fact that the DAG size for Ethereum is 5127 Mbytes, while the Arc A380 card has 4832 Mbytes of memory available to the user.
The card itself has 6 GB of GDDR6 memory on board, but some of it is spent on operating system graphics.
Intel Arc A380 in mining Ethereum Classic (ETH) is expected to switch to Proof of Stake model in September, so mining this altcoin on any video card will not be possible.For this case Nanominer supports automatic algorithm change for Ethereum Classic (ETC) mining, as demonstrated by Red Panda Mining blogger in the video above.
