Unfortunately so far these are underwhelming. Hope AMD figures out a fix for the very high idle (>100 W) consumption when more than one monitor is connected (idle with a single monitor is also bad, but not quite as egregious). In terms of performance they're good, but the much lower efficiency (20-50 % lower) compared to NV Ada suggests to me that AMD aimed for a lower performance level and had to bump performance up on short notice. The high power draw through the slot, which GPUs generally avoid nowadays for a number of reasons, also seems to suggest this - AMD is clearly trying to get every single Watt into the card they can. Non-reference cards more or less all have three eight pin power connectors - I'd go so far as to say the two connectors on the reference cards are basically marketing to seem more efficient.
Though even with European electricity prices, the generally higher (real world) power consumption of these doesn't make the (more expensive) 4080 a better deal. Maybe if prices cross over the 1 buck/kWh threshold. Never say never!
The smart move is to wait a couple months and see if AMD can fix the bigger issues with these cards through drivers and only buy one of these if they do.
