Seems like poorly hidden attempt to jump on mining market train.
There has so far been zero real discussion (by Intel) about mining and Xe Graphics. I'm not saying it hasn't looked into the possibilities mining presents, but publicly at least Intel is focused on data center stuff (machine learning, HPC, etc.) and is using gaming as a way to leverage that on the consumer side. Theoretically, Xe might work fine for mining as well, but that will be predicated almost entirely on how much memory bandwidth it brings to the table. Indications so far are that Xe DG2 stuff (aka Arc) will use GDDR6, probably in a 256-bit interface at the very top. That means similar bandwidth to the RTX 3060 Ti and RX 6800, or around 60-ish MH/s for Ethereum mining. Unless Intel has some way to boost performance without increasing bandwidth, or it decides to make a card with a 384-bit or 512-bit memory interface, mining performance will at best match the cards that already fall around the 500-650 GB/s bandwidth mark.
And of course, there's the fact that Intel started talking about Xe Graphics and its discrete GPU aspirations back in 2018, when mining was not at all a major factor in GPU sales. Nvidia and AMD weren't talking about mining in 2018/2019 either. Everyone got hot and bothered about mining (again) starting in late 2020 and early 2021. It will be interesting to see if Intel's GPUs even work with existing mining software — the DG1 at least basically failed to run any of the normal algorithms when I tried it out. But drivers and software updates can fix that, if there's a reason to do so.
