Would be interesting to hear from someone who has actually used a game console to mine
You wouldn't find anyone who's in for profit.
Those articles are doing it for publicity purposes;
The ones that actually show the process must be doing it to show that it's possible, not for mining profit.
That specific article however, is a bad example because it looks like the PS4s are there to gain "
rare FIFA players" rather than mining.
There's no shown evidence that they are mining, the GPUs in that facility must be the ones that are mining.
But technically, it can produce SHA256d hashes but not high enough to mine Bitcoins (
even pools wont accept your hashes).
It could mine altcoins though but while playing FIFA (
described in the article), still possible but not reasonable.
