See how different that is to Steve Burke's conclusions?
Actually, Owen has previously been positive about Arc. It all comes down to the games you run. One mix of games gives good results; another mix gives bad results. There's only so much time and they report what they find. That's why it's important to look at multiple reviews.
Having thought about his video a while I think this says more about game developers than Intel: they test their games on Nvidia and AMD GPUs well before release so bugs get reported and fixed. Notice how so often both have 'game ready drivers': this means that the old driver had problems with the game and that Nvidia and AMD have fixed those issues. But I expect they don't bother with Intel so Intel is months behind.
As for review sites, Hardware Unboxed were - much to their discredit - hugely contemptuous of Intel Arc well after release, often simply not bothering to include Arc in their tests. I'll take the honesty of Burke & Owen over HUB any day.
