Honestly, I think the comment about LPDDR5 in the article is very telling...
Yes, TFLOPS are not truly indicative of real world performance, but considering a ~14% difference in power, why couldnt this thing EASILY run 1440p or 4k at 30 like the Series S or PS5? Series S has 4 TFLOPS and targets 1440p at 60 for most games...
