Not enough verified runs yet for a fair pool verdict — averages appear once each side has at least five.
Verdict — RTX 3080
Great card in its era. If you have one, keep it — it's still perfectly capable. Newer cards match its performance at half the power draw.
Verdict — Arc B580
Intel finally got graphics right. The B580 is genuinely competitive on price/performance and 12 GB helps it age. Drivers are much improved but occasional oddity remains.
