The 1050 Ti was pretty good for the time, all that gen were. I guess the RX 6400 is the closest equivalent and it does pretty well (on PCI-E 4.0) for no power connector, but many reviewers were very disappointed with the performance (it is not an upgrade to a 1050 Ti, despite releasing 5+ years later). The 6500 XT seems to have too high clocks and voltage. The 3050 is not really in the same tier anymore when it costs £300 odd. Nvidia haven't replaced the 1650 in the market for 75 watt cards yet.
Not really a 1650 replacement, but that RTX A2000 pulls <70w and provides in between 3050 and 3060 performance.
Shame about the £700 price tag!
